| Tema Actuator ETF | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | As with all funds, a shareholder is subject to the risk that his or her investment could lose money. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any government agency. The principal risks affecting shareholders’ investments in the Fund are set forth below.
|
|||||||||||||||||||||
| Tema Actuator ETF | Absence Of Prior Active Market Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Absence of Prior Active Market Risk. While the Fund’s shares are listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained. The Fund’s Distributor does not maintain a secondary market in shares.
|
|||||||||||||||||||||
| Tema Actuator ETF | Actively Managed Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Actively Managed Risk. The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns, which may cause the Fund to fail to meet its investment objective or to underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active trading that can accompany active management may result in high portfolio turnover, which may have a negative impact on performance. Active trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund. Active trading may also result in adverse tax consequences.

|||||||||||||||||||||
| Tema Actuator ETF | Artificial Intelligence Technology Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Artificial Intelligence Technology Risk. Companies in the artificial intelligence (“AI”) and technology industries typically have high research and capital expenditures and, as a result, their profitability can vary widely, if they are profitable at all. The space in which they are engaged is highly competitive and issuers’ products and services may become obsolete very quickly. These companies are heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. The issuers are also subject to legal, regulatory and political changes that may have a large impact on their profitability. A failure in an issuer’s product or even questions about the safety of the product could be devastating to the issuer, especially if it is the marquee product of the issuer. It can be difficult to accurately capture what qualifies as an AI and Technology company.
|
|||||||||||||||||||||
| Tema Actuator ETF | Authorized Participant Concentration Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Authorized Participant Concentration Risk. Only an Authorized Participant (as defined below) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that act as Authorized Participants. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may trade at a discount to net asset value per share (“NAV”) and possibly face trading halts and/or delisting.
|
|||||||||||||||||||||
| Tema Actuator ETF | Common Stock Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Common Stock Risk. Common stock holds the lowest priority in the capital structure of a company, and, therefore, takes the largest share of the company’s risk and its accompanying volatility. The value of the common stock held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or facts relating to specific companies in which the Fund invests.
|
|||||||||||||||||||||
| Tema Actuator ETF | Currency Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Currency Risk. The Fund may invest its assets in securities denominated in non-U.S. currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of the shares. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of the non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the value of the Fund’s holdings, measured in the foreign currency, increases. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.
|
|||||||||||||||||||||
| Tema Actuator ETF | Cybersecurity And Disaster Recovery Risks [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Cybersecurity and Disaster Recovery Risks. Information and technology systems relied upon by the Fund, the Adviser, the Fund’s other service providers (including, but not limited to, the Fund Accountant, Custodian, Transfer Agent, Administrator and Distributor), market makers, Authorized Participants, financial intermediaries and/or the issuers of securities in which the Fund invests may be vulnerable to damage or interruption from computer viruses, network failures, computer and telecommunication failures, infiltration by unauthorized persons, security breaches, usage errors, power outages and catastrophic events such as fires, tornadoes, floods, hurricanes and earthquakes. Although the Adviser and the Fund’s other service providers have implemented measures to manage risks relating to these types of events, if these systems are compromised, become inoperable for extended periods of time or cease to function properly, significant investment may be required to fix or replace them. The failure of these systems and/or of disaster recovery plans could cause significant interruptions in the operations of the Fund, the Adviser, the Fund’s other service providers, market makers, Authorized Participants, financial intermediaries and/or issuers of securities in which the Fund invests and may result in a failure to maintain the security, confidentiality or privacy of sensitive data, impact the Fund’s ability to calculate its NAV or impede trading.
|
|||||||||||||||||||||
| Tema Actuator ETF | Depositary Receipt Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Depositary Receipt Risk. The Fund may invest in depositary receipts which involve similar risks to those associated with investments in foreign securities. Investments in depositary receipts may be less liquid than the underlying shares in their primary trading market.
ADRs and GDRs may be subject to some of the same risks as direct investment in foreign companies, which includes international trade, currency, political, regulatory and diplomatic risks. In a sponsored ADR or GDR arrangement, the foreign issuer assumes the obligation to pay some or all of the depositary’s transaction fees. Under an unsponsored ADR or GDR arrangement, the foreign issuer assumes no obligations and the depositary’s transaction fees are paid directly by the ADR or GDR holders. Because unsponsored ADR and GDR arrangements are organized independently and without the cooperation of the issuer of the underlying securities, available information concerning the foreign issuer may not be as current as for sponsored ADRs and GDRs and voting rights with respect to the deposited securities that are not passed through.
|
|||||||||||||||||||||
| Tema Actuator ETF | Earlystage And Prerevenue Company Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Early-Stage and Pre-Revenue Company Risk. The Fund may invest in early-stage, development-phase, or recently public companies that may not yet generate meaningful revenues or profits. These companies may face significant uncertainty regarding the successful development, commercialization, and market acceptance of their products and technologies.
|
|||||||||||||||||||||
| Tema Actuator ETF | Early Closetrading Halt Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Early Close/Trading Halt Risk. An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.
|
|||||||||||||||||||||
| Tema Actuator ETF | Etf Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | ETF Risk. The Fund is structured as an ETF. As a result, the Fund is subject to special risks, including:
Additionally, purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund’s NAV to the extent not offset by a transaction fee payable by an AP.
|
|||||||||||||||||||||
| Tema Actuator ETF | Fluctuation Of Net Asset Value Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Fluctuation of Net Asset Value Risk. The NAV of the Fund’s shares will generally fluctuate with changes in the market value of the Fund’s holdings. The market prices of the shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of and demand for shares on [ ] (the “Exchange”). The Adviser cannot predict whether the shares will trade below, at or above their NAV. The Fund’s market price may deviate from the value of its underlying portfolio holdings, particularly in times of market stress, with the result that investors may pay significantly more or receive significantly less than the underlying value of the Fund shares bought or sold. This can be reflected as a spread between the bid and ask prices for the Fund quoted during the day or a premium or discount in the closing price from the Fund’s NAV. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material effect on the market price of the Fund’s shares.
|
|||||||||||||||||||||
| Tema Actuator ETF | Foreign Custody Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.
|
|||||||||||||||||||||
| Tema Actuator ETF | Foreign Securities Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Foreign Securities Risk. Investments in securities (including ADRs and GDRs) of foreign issuers involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers. The values of foreign investments may be affected by changes in exchange control regulations, application of foreign tax laws (including withholding tax) changes in governmental administration or economic or monetary policy (in this country or abroad) or changed circumstances in dealings between nations. The value of foreign securities is also affected by the value of the local currency relative to the U.S. Dollar. GDRs may be other than dollar denominated and may be issued in several countries.
|
|||||||||||||||||||||
| Tema Actuator ETF | Geographic Investment Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Geographic Investment Risk. To the extent the Fund is significantly comprised of securities of issuers from a single country, the Fund would be more likely to be impacted by events or conditions affecting that country.
Chinese Securities Risk. A portion of the Fund’s assets may be invested in companies exposed to China. Risks affecting investments in China include a potential downturn in the Chinese economy, reduced liquidity or increased price volatility in the Chinese securities markets as a result of trading suspensions affecting Chinese issuers or other factors, the potential that the Chinese government may expand restrictions on foreign investments or the repatriation of capital, and the implementation of new tariffs or other trade barriers by China or its trading partners. A lack of transparency respecting Chinese companies may also reduce the Fund’s ability to conduct diligence respecting those companies’ accounting and governance standards, which may in turn reduce the Fund’s ability to detect fraudulent practices that may adversely affect the companies’ stock prices.
European Securities Risk. The Fund is more exposed to the economic and political risks of Europe and of the European countries in which it invests than funds whose investments are more geographically diversified. Adverse economic and political events, including war, in Europe may cause the Fund’s investments to decline in value. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member states of the European Union (the “EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have historically experienced volatility and adverse trends and these events have and may in the future adversely affect the exchange rate of the euro and may significantly affect other European countries.
Japanese Securities Risk. Because a portion of the assets of the Fund may be invested in Japanese securities, the Fund’s performance may be tied to the political, social and economic conditions within Japan. The Japanese economy has at times in the past been negatively affected by government intervention and protectionism, a deflationary macroeconomic environment, a heavy reliance on international trade and natural disasters. These factors, as well as an aging population, increases in government debt and changes to fiscal, monetary, or trade policies, may affect Japanese markets and the Fund’s performance. As such, the Fund’s performance may be more volatile than the performance of funds that are more geographically diverse.
South Korean Securities Risk. Investments in South Korean issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to South Korea. In addition, economic and political developments of South Korea’s neighbors, including escalated tensions involving North Korea and any outbreak of hostilities involving North Korea, or even the threat of an outbreak of hostilities, may have a severe adverse effect on the South Korean economy.
|
|||||||||||||||||||||
| Tema Actuator ETF | Industry Concentration Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Industry Concentration Risk. Because the Fund’s assets will be concentrated in an industry or group of industries, the Fund is subject to loss due to adverse occurrences that may affect that industry or group of industries.
|
|||||||||||||||||||||
| Tema Actuator ETF | Investment Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Investment Risk. An investment in the Fund is subject to investment risk including the possible loss of the entire principal amount that you invest.
|
|||||||||||||||||||||
| Tema Actuator ETF | Issuerspecific Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Issuer-Specific Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund.
|
|||||||||||||||||||||
| Tema Actuator ETF | Largecapitalization Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Large-Capitalization Risk. Returns on investments in securities of large companies could trail the returns on investments in securities of smaller and mid-sized companies. The securities of large-capitalization companies may also be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
|
|||||||||||||||||||||
| Tema Actuator ETF | Market Risk And Selection Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Market Risk and Selection Risk. The prices of securities held by the Fund may decline in response to certain events taking place around the world, including those directly involving the companies whose securities are owned by the Fund; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency, interest rate and commodity price fluctuations. The equity securities purchased by the Fund may involve large price swings and potential for loss. Investors in the Fund should have a long-term perspective and be able to tolerate potentially sharp declines in value. The market’s daily movements, sometimes called volatility, may be greater or less depending on the types of securities the Fund owns and the markets in which the securities trade. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, climate change or climate related risks, natural disasters, pandemics, epidemics, war, terrorism, regulatory events, governmental or quasi-governmental actions, and public health emergencies. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets.
|
|||||||||||||||||||||
| Tema Actuator ETF | Microcapitalization Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Micro-Capitalization Risk. The micro-capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies, and may underperform other segments of the market or the equity market as a whole. Securities of micro-capitalization companies generally trade in lower volumes, are often more vulnerable to market volatility, and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole.
|
|||||||||||||||||||||
| Tema Actuator ETF | National Closed Market Trading Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | National Closed Market Trading Risk. To the extent that securities or other assets held by the Fund trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between such asset’s current price and its last quoted price (i.e., the quote from the closed foreign market to the Fund). The impact of a closed foreign market on the Fund is likely to be greater where a large portion of the Fund’s holdings trade on a closed foreign market or when a foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other funds.
|
|||||||||||||||||||||
| Tema Actuator ETF | New Fund Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | New Fund Risk. A new or smaller fund is subject to the risk that its performance may not represent how the fund is expected to or may perform in the long term. In addition, new funds have limited operating histories for investors to evaluate and new and smaller funds may not attract sufficient assets to achieve investment and trading efficiencies. There can be no assurance that the Fund will achieve an economically viable size. Further, an active trading market for shares of the Fund may not develop or be maintained.
|
|||||||||||||||||||||
| Tema Actuator ETF | Nondiversified Fund Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Non-Diversified Fund Risk. The Fund is a non-diversified investment company under the Investment Company Act of 1940 (the “1940 Act”), meaning that, as compared to a diversified fund, it can invest a greater percentage of its assets in securities issued by or representing a small number of issuers. As a result, the performance of these issuers can have a substantial impact on the Fund’s performance.
|
|||||||||||||||||||||
| Tema Actuator ETF | Operational Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third parties, failed or inadequate processes and technology or systems failures. The Fund seeks to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.
|
|||||||||||||||||||||
| Tema Actuator ETF | Privately Placed Securities Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Privately Placed Securities Risk. The Fund may invest in non-exchange traded securities, including privately placed securities, which are subject to liquidity and valuation risks. These risks may make it difficult for those securities to be traded or valued, especially in the event of adverse economic and liquidity conditions or adverse changes in the issuer’s financial condition. The market for certain non-exchange traded securities may be limited to institutional investors, subjecting such investments to further liquidity risk if a market were to limit institutional trading. There may also be less information available regarding such non-exchange traded securities than for publicly traded securities, which may make it more difficult for the Adviser to fully evaluate the risks of investing in such securities and as a result place the Fund’s assets at greater risk of loss than if the Adviser had more complete information. In addition, the issuers of non-exchange traded securities may be distressed, insolvent, or delinquent in filing information needed to be listed on an exchange. Disposing of nonexchange traded securities, including privately placed securities, may involve time-consuming negotiation and legal expenses, and selling them promptly at an acceptable price may be difficult or impossible. Securities purchased in private placements may be subject to legal or contractual restrictions on resale. The Fund may have to bear the expense of registering restricted securities for resale and the risk of substantial delay in effecting registration.
The Fund may have exposure to restricted securities. Restricted securities are securities with restrictions on public resale, such as securities offered in accordance with an exemption under Rule 144A under the Securities Act of 1933 (the “1933 Act”), or commercial paper issued under Section 4(a)(2) of the 1933 Act. Restricted securities are often required to be sold in private sales to institutional buyers, markets for restricted securities may or may not be well developed, and restricted securities can be illiquid. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions or other economic and market impediments. Funds with principal investment strategies that involve investments in securities of companies with smaller market capitalizations, foreign securities, derivatives, or securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk. Exposure to liquidity risk may be heightened for funds that invest in securities of emerging markets and related derivatives that are not widely traded, and that may be subject to purchase and sale restrictions.
|
|||||||||||||||||||||
| Tema Actuator ETF | Proprietary Infrastructure Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Proprietary Infrastructure Risk. The success of the Fund’s investment strategy depends in part on the ability of the companies in which it invests to maintain proprietary technology used in their products and services. Companies in which the Fund invests will rely, in part, on patent, trade secret and trademark law to protect that technology, but competitors may misappropriate their intellectual property, and disputes as to ownership of intellectual property may arise. Consequently, companies in which the Fund invests may, from time to time, be required to institute litigation in order to enforce their patents, copyrights or other intellectual property rights, to protect their trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement. Such litigation could result in substantial costs and diversion of resources. Similarly, if a company is found to infringe upon or misappropriate a third-party’s patent or other proprietary rights, that company could be required to pay damages to such third-party, alter its own products or processes, obtain a license from the third-party and/or cease activities utilizing such proprietary rights, including making or selling products utilizing such proprietary rights.
|
|||||||||||||||||||||
| Tema Actuator ETF | Rare Earth And Critical Materials Companies Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Rare Earth and Critical Materials Companies Risk. The Fund will be sensitive to, and its performance will depend to a greater extent on, the overall condition of Rare Earth and Critical Materials Companies. Rare earth and critical materials are industrial metals that are typically mined as by-products or secondary metals in operations focused on precious metals and base metals. Compared to base metals, they have more specialized uses. Rare earth metals (or rare earth elements) are a collection of chemical elements that are crucial to many of the world’s most advanced technologies. Consequently, the demand for rare earth and critical materials has strained supply, which has the potential to result in a shortage of such materials which could adversely affect the companies in the Fund’s portfolio. Companies involved in the various activities that are related to the mining, production, recycling, mineral sands, processing and/or refining of rare earth and critical materials tend to be small-, medium- and micro-capitalization companies with volatile share prices, are highly dependent on the price of rare earth and critical materials, which may fluctuate substantially over short periods of time. The value of such companies may be significantly affected by events relating to international, national and local political and economic developments, energy conservation efforts, the success of exploration projects, commodity prices, tax and other government regulations, depletion of resources, and mandated expenditures for safety and pollution control devices. The mining, production, recycling, processing and/or refining of rare earth and critical metals can be capital intensive and, if companies involved in such activities are not managed well, the share prices of such companies could decline even as prices for the underlying rare earth and critical metals are rising. In addition, companies involved in the various activities that are related to the mining, production, recycling, processing and/or refining of rare earth and critical metals may be at risk for environmental damage claims.
|
|||||||||||||||||||||
| Tema Actuator ETF | Sector Focus Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Sector Focus Risk. The Fund may invest a significant portion of its assets in one or more sectors and thus will be more susceptible to the risks affecting those sectors than funds that have more diversified holdings across a number of sectors. The Fund anticipates that it may be subject to some or all of the risks described below.
Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on their profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of any of these rights may adversely affect the profitability of these companies or the Fund’s performance.
|
|||||||||||||||||||||
| Tema Actuator ETF | Semiconductor Company Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Semiconductor Company Risk. Competitive pressures may have a significant effect on the financial condition of companies in the semiconductor industry. As product cycles shorten and manufacturing capacity increases, these companies may become increasingly subject to aggressive pricing, which hampers profitability. Semiconductor companies are vulnerable to wide fluctuations in securities prices due to rapid product obsolescence. Many semiconductor companies may not successfully introduce new products, develop and maintain a loyal customer base or achieve general market acceptance for their products, and failure to do so could have a material adverse effect on their business, results of operations and financial condition. Reduced demand for end-user products, underutilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductor industry. Semiconductor companies typically face high capital costs and these companies may need additional financing, which may be difficult to obtain. They also may be subject to risks relating to research and development costs and the availability and price of components. Moreover, they may be heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. Some of the companies involved in the semiconductor sector are also engaged in other lines of business unrelated to the semiconductor business, and they may experience problems with these lines of business, which could adversely affect their operating results. The international operations of many semiconductor companies expose them to risks associated with instability and changes in economic and political conditions, foreign currency fluctuations, changes in foreign regulations, tariffs and trade disputes, competition from subsidized foreign competitors with lower production costs and other risks inherent to international business. The semiconductor industry is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. Companies in the semiconductor industry also may be subject to competition from new market entrants. The stock prices of companies in the semiconductor industry have been and will likely continue to be extremely volatile compared to the overall market.
|
|||||||||||||||||||||
| Tema Actuator ETF | Securities Lending Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Securities Lending Risk. Although the Fund will receive collateral in connection with all loans of its securities holdings, the Fund would be exposed to a risk of loss should a borrower default on its obligation to return the borrowed securities (e.g., the loaned securities may have appreciated beyond the value of the collateral held by the Fund). In addition, the Fund will bear the risk of loss of any cash collateral that it invests.
|
|||||||||||||||||||||
| Tema Actuator ETF | Small And Midcapitalization Company Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Small- and Mid-Capitalization Company Risk. The small- and mid-capitalization companies in which the Fund invests may be more vulnerable to adverse business or economic events than larger, more established companies, and may underperform other segments of the market or the equity market as a whole. Securities of small- and mid-capitalization companies generally trade in lower volumes, are often more vulnerable to market volatility, and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole.
|
|||||||||||||||||||||
| Tema Actuator ETF | Valuation Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons.
|
|||||||||||||||||||||
| Tema Actuator ETF | Valueoriented Investment Strategies Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Value-Oriented Investment Strategies Risk. The Fund seeks to invest in stocks that are believed to be undervalued in comparison to their fundamentals and growth opportunities. Value investing is subject to the risk that the market will not recognize a security’s inherent value for a long time or at all, or that a stock judged to be undervalued may actually be appropriately priced or overvalued. In addition, during some periods (which may be extensive), value stocks generally may be out of favor in the markets. |
|||||||||||||||||||||
| Tema Actuator ETF | Risk Lose Money [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | As with all funds, a shareholder is subject to the risk that his or her investment could lose money. | |||||||||||||||||||||
| Tema Actuator ETF | Risk Not Insured [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any government agency. | |||||||||||||||||||||
| Tema Actuator ETF | Risk Nondiversified Status [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | The Fund is a non-diversified investment company under the Investment Company Act of 1940 (the “1940 Act”), meaning that, as compared to a diversified fund, it can invest a greater percentage of its assets in securities issued by or representing a small number of issuers. As a result, the performance of these issuers can have a substantial impact on the Fund’s performance. | |||||||||||||||||||||
| Tema CPU ETF | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | As with all funds, a shareholder is subject to the risk that his or her investment could lose money. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any government agency. The principal risks affecting shareholders’ investments in the Fund are set forth below.
|
|||||||||||||||||||||
| Tema CPU ETF | Absence Of Prior Active Market Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Absence of Prior Active Market Risk. While the Fund’s shares are listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained. The Fund’s Distributor does not maintain a secondary market in shares.
|
|||||||||||||||||||||
| Tema CPU ETF | Actively Managed Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Actively Managed Risk. The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns, which may cause the Fund to fail to meet its investment objective or to underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active trading that can accompany active management may result in high portfolio turnover, which may have a negative impact on performance.

| Tema CPU ETF | Artificial Intelligence Technology Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Artificial Intelligence Technology Risk. Companies in the AI and technology industries typically have high research and capital expenditures and, as a result, their profitability can vary widely, if they are profitable at all. The space in which they are engaged is highly competitive and issuers’ products and services may become obsolete very quickly. These companies are heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. The issuers are also subject to legal, regulatory and political changes that may have a large impact on their profitability. A failure in an issuer’s product or even questions about the safety of the product could be devastating to the issuer, especially if it is the marquee product of the issuer. It can be difficult to accurately capture what qualifies as an AI and Technology company.

| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Authorized Participant Concentration Risk. Only an Authorized Participant (as defined below) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that act as Authorized Participants. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may trade at a discount to net asset value per share (“NAV”) and possibly face trading halts and/or delisting.

| Tema CPU ETF | Common Stock Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Common Stock Risk. Common stock holds the lowest priority in the capital structure of a company, and, therefore, takes the largest share of the company’s risk and its accompanying volatility. The value of the common stock held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or facts relating to specific companies in which the Fund invests.

| Tema CPU ETF | Currency Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Currency Risk. The Fund may invest its assets in securities denominated in non-U.S. currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of the shares. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of the non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the value of the Fund’s holdings, measured in the foreign currency, increases. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

| Risk [Text Block] | Cybersecurity and Disaster Recovery Risks. Information and technology systems relied upon by the Fund, the Adviser, the Fund’s other service providers (including, but not limited to, the Fund Accountant, Custodian, Transfer Agent, Administrator and Distributor), market makers, Authorized Participants, financial intermediaries and/or the issuers of securities in which the Fund invests may be vulnerable to damage or interruption from computer viruses, network failures, computer and telecommunication failures, infiltration by unauthorized persons, security breaches, usage errors, power outages and catastrophic events such as fires, tornadoes, floods, hurricanes and earthquakes. Although the Adviser and the Fund’s other service providers have implemented measures to manage risks relating to these types of events, if these systems are compromised, become inoperable for extended periods of time or cease to function properly, significant investment may be required to fix or replace them. The failure of these systems and/or of disaster recovery plans could cause significant interruptions in the operations of the Fund, the Adviser, the Fund’s other service providers, market makers, Authorized Participants, financial intermediaries and/or issuers of securities in which the Fund invests and may result in a failure to maintain the security, confidentiality or privacy of sensitive data, impact the Fund’s ability to calculate its NAV or impede trading.

| Tema CPU ETF | Depositary Receipt Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Depositary Receipt Risk. The Fund may invest in depositary receipts which involve similar risks to those associated with investments in foreign securities. Investments in depositary receipts may be less liquid than the underlying shares in their primary trading market.
ADRs and GDRs may be subject to some of the same risks as direct investment in foreign companies, which includes international trade, currency, political, regulatory and diplomatic risks. In a sponsored ADR or GDR arrangement, the foreign issuer assumes the obligation to pay some or all of the depositary’s transaction fees. Under an unsponsored ADR or GDR arrangement, the foreign issuer assumes no obligations and the depositary’s transaction fees are paid directly by the ADR or GDR holders. Because unsponsored ADR and GDR arrangements are organized independently and without the cooperation of the issuer of the underlying securities, available information concerning the foreign issuer may not be as current as for sponsored ADRs and GDRs and voting rights with respect to the deposited securities that are not passed through.

An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

| Risk [Text Block] | ETF Risk. The Fund is structured as an ETF. As a result, the Fund is subject to special risks, including:
Additionally, purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund’s NAV to the extent not offset by a transaction fee payable by an AP.

|||||||||||||||||||||
| Tema CPU ETF | Fluctuation Of Net Asset Value Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Fluctuation of Net Asset Value Risk. The NAV of the Fund’s shares will generally fluctuate with changes in the market value of the Fund’s holdings. The market prices of the shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of and demand for shares on NYSE Arca, Inc. (the “Exchange”). The Adviser cannot predict whether the shares will trade below, at or above their NAV. The Fund’s market price may deviate from the value of its underlying portfolio holdings, particularly in times of market stress, with the result that investors may pay significantly more or receive significantly less than the underlying value of the Fund shares bought or sold. This can be reflected as a spread between the bid and ask prices for the Fund quoted during the day or a premium or discount in the closing price from the Fund’s NAV. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material effect on the market price of the Fund’s shares.

| Risk [Text Block] | Foreign Securities Risk. Investments in securities (including ADRs and GDRs) of foreign issuers involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers. The values of foreign investments may be affected by changes in exchange control regulations, application of foreign tax laws (including withholding tax) changes in governmental administration or economic or monetary policy (in this country or abroad) or changed circumstances in dealings between nations. The value of foreign securities is also affected by the value of the local currency relative to the U.S. Dollar. GDRs may be other than dollar denominated and may be issued in several countries.

| Tema CPU ETF | Geographic Investment Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Geographic Investment Risk. To the extent the Fund is significantly comprised of securities of issuers from a single country, the Fund would be more likely to be impacted by events or conditions affecting that country.
Chinese Securities Risk. A portion of the Fund’s assets may be invested in companies exposed to China. Risks affecting investments in China include a potential downturn in the Chinese economy, reduced liquidity or increased price volatility in the Chinese securities markets as a result of trading suspensions affecting Chinese issuers or other factors, the potential that the Chinese government may expand restrictions on foreign investments or the repatriation of capital, and the implementation of new tariffs or other trade barriers by China or its trading partners. A lack of transparency respecting Chinese companies may also reduce the Fund’s ability to conduct diligence respecting those companies’ accounting and governance standards, which may in turn reduce the Fund’s ability to detect fraudulent practices that may adversely affect the companies’ stock prices.
European Securities Risk. The Fund is more exposed to the economic and political risks of Europe and of the European countries in which it invests than funds whose investments are more geographically diversified. Adverse economic and political events, including war, in Europe may cause the Fund’s investments to decline in value. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member states of the European Union (the “EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have historically experienced volatility and adverse trends and these events have and may in the future adversely affect the exchange rate of the euro and may significantly affect other European countries.
Japanese Securities Risk. Because a portion of the assets of the Fund may be invested in Japanese securities, the Fund’s performance may be tied to the political, social and economic conditions within Japan. The Japanese economy has at times in the past been negatively affected by government intervention and protectionism, a deflationary macroeconomic environment, a heavy reliance on international trade and natural disasters. These factors, as well as an aging population, increases in government debt and changes to fiscal, monetary, or trade policies, may affect Japanese markets and the Fund’s performance. As such, the Fund’s performance may be more volatile than the performance of funds that are more geographically diverse.
South Korean Securities Risk. Investments in South Korean issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to South Korea. In addition, economic and political developments of South Korea’s neighbors, including escalated tensions involving North Korea and any outbreak of hostilities involving North Korea, or even the threat of an outbreak of hostilities, may have a severe adverse effect on the South Korean economy.

| Tema CPU ETF | Industry Concentration Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Industry Concentration Risk. Because the Fund’s assets will be concentrated in an industry or group of industries, the Fund is subject to loss due to adverse occurrences that may affect that industry or group of industries.
AI Companies Risk. AI companies may be characterized by concentrated product offerings, limited market reach, constrained financial resources, or restricted personnel capacity. The securities of such companies may exhibit greater price volatility relative to securities of companies that rely less on technology. The accelerated pace of technological evolution affecting a company’s product portfolio may exert materially adverse effects on its operating performance. Companies operating within the AI sector rely substantially upon a framework of intellectual property protections, including patents, copyrights, trademarks, and trade secret laws, to establish and maintain proprietary rights in their products and technological innovations. No assurance can be provided that protective measures implemented by such companies will prove sufficient to prevent misappropriation of their technology, nor that competitors will not independently develop substantially equivalent or superior technologies. AI companies typically allocate significant capital expenditures toward research and development initiatives. However, there is no guarantee that products or services resulting from such investments will achieve commercial viability or success.
Semiconductor Industry Risk. Semiconductor companies face intense competition, both domestically and internationally, and such competition may have an adverse effect on profit margins. Semiconductor companies may have limited product lines, markets, financial resources or personnel. The products of semiconductor companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Capital equipment expenditures could be substantial, and equipment generally suffers from rapid obsolescence. Companies in the semiconductor industry are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights would adversely affect the profitability of these companies.

Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

| Tema CPU ETF | Market Risk And Selection Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Market Risk and Selection Risk. The prices of securities held by the Fund may decline in response to certain events taking place around the world, including those directly involving the companies whose securities are owned by the Fund; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency, interest rate and commodity price fluctuations. The equity securities purchased by the Fund may involve large price swings and potential for loss. Investors in the Fund should have a long-term perspective and be able to tolerate potentially sharp declines in value. The market’s daily movements, sometimes called volatility, may be greater or less depending on the types of securities the Fund owns and the markets in which the securities trade. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, climate change or climate related risks, natural disasters, pandemics, epidemics, war, terrorism, regulatory events, governmental or quasi-governmental actions, and public health emergencies. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets.

The micro-capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies, and may underperform other segments of the market or the equity market as a whole. Securities of micro-capitalization companies generally trade in lower volumes, are often more vulnerable to market volatility, and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole.

| Risk [Text Block] | National Closed Market Trading Risk. To the extent that securities or other assets held by the Fund trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between such asset’s current price and its last quoted price (i.e., the quote from the closed foreign market to the Fund). The impact of a closed foreign market on the Fund is likely to be greater where a large portion of the Fund’s holdings trade on a closed foreign market or when a foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other funds.

| Risk [Text Block] | New Fund Risk. A new or smaller fund is subject to the risk that its performance may not represent how the fund is expected to or may perform in the long term. In addition, new funds have limited operating histories for investors to evaluate and new and smaller funds may not attract sufficient assets to achieve investment and trading efficiencies. There can be no assurance that the Fund will achieve an economically viable size. Further, an active trading market for shares of the Fund may not develop or be maintained.

The Fund seeks to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

| Tema CPU ETF | Privately Placed Securities Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Privately Placed Securities Risk. The Fund may invest in non-exchange traded securities, including privately placed securities, which are subject to liquidity and valuation risks. These risks may make it difficult for those securities to be traded or valued, especially in the event of adverse economic and liquidity conditions or adverse changes in the issuer’s financial condition. The market for certain non-exchange traded securities may be limited to institutional investors, subjecting such investments to further liquidity risk if a market were to limit institutional trading. There may also be less information available regarding such non-exchange traded securities than for publicly traded securities, which may make it more difficult for the Adviser to fully evaluate the risks of investing in such securities and as a result place the Fund’s assets at greater risk of loss than if the Adviser had more complete information. In addition, the issuers of non-exchange traded securities may be distressed, insolvent, or delinquent in filing information needed to be listed on an exchange. Disposing of nonexchange traded securities, including privately placed securities, may involve time-consuming negotiation and legal expenses, and selling them promptly at an acceptable price may be difficult or impossible. Securities purchased in private placements may be subject to legal or contractual restrictions on resale. The Fund may have to bear the expense of registering restricted securities for resale and the risk of substantial delay in effecting registration.
The Fund may have exposure to restricted securities. Restricted securities are securities with restrictions on public resale, such as securities offered in accordance with an exemption under Rule 144A under the Securities Act of 1933 (the “1933 Act”), or commercial paper issued under Section 4(a)(2) of the 1933 Act. Restricted securities are often required to be sold in private sales to institutional buyers, markets for restricted securities may or may not be well developed, and restricted securities can be illiquid. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions or other economic and market impediments. Funds with principal investment strategies that involve investments in securities of companies with smaller market capitalizations, foreign securities, derivatives, or securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk. Exposure to liquidity risk may be heightened for funds that invest in securities of emerging markets and related derivatives that are not widely traded, and that may be subject to purchase and sale restrictions.

| Tema CPU ETF | Proprietary Infrastructure Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Proprietary Infrastructure Risk. The success of the Fund’s investment strategy depends in part on the ability of the companies in which it invests to maintain proprietary technology used in their products and services. Companies in which the Fund invests will rely, in part, on patent, trade secret and trademark law to protect that technology, but competitors may misappropriate their intellectual property, and disputes as to ownership of intellectual property may arise. Consequently, companies in which the Fund invests may, from time to time, be required to institute litigation in order to enforce their patents, copyrights or other intellectual property rights, to protect their trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement. Such litigation could result in substantial costs and diversion of resources. Similarly, if a company is found to infringe upon or misappropriate a third-party’s patent or other proprietary rights, that company could be required to pay damages to such third-party, alter its own products or processes, obtain a license from the third-party and/or cease activities utilizing such proprietary rights, including making or selling products utilizing such proprietary rights.

The Fund anticipates that it may be subject to some or all of the risks described below.
Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on their profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of any of these rights may adversely affect the profitability of these companies or the Fund’s performance.

| Tema CPU ETF | Semiconductor Company Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Semiconductor Company Risk. Competitive pressures may have a significant effect on the financial condition of companies in the semiconductor industry. As product cycles shorten and manufacturing capacity increases, these companies may become increasingly subject to aggressive pricing, which hampers profitability. Semiconductor companies are vulnerable to wide fluctuations in securities prices due to rapid product obsolescence. Many semiconductor companies may not successfully introduce new products, develop and maintain a loyal customer base or achieve general market acceptance for their products, and failure to do so could have a material adverse effect on their business, results of operations and financial condition. Reduced demand for end-user products, underutilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductor industry. Semiconductor companies typically face high capital costs and these companies may need
additional financing, which may be difficult to obtain. They also may be subject to risks relating to research and development costs and the availability and price of components. Moreover, they may be heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. Some of the companies involved in the semiconductor sector are also engaged in other lines of business unrelated to the semiconductor business, and they may experience problems with these lines of business, which could adversely affect their operating results. The international operations of many semiconductor companies expose them to risks associated with instability and changes in economic and political conditions, foreign currency fluctuations, changes in foreign regulations, tariffs and trade disputes, competition from subsidized foreign competitors with lower production costs and other risks inherent to international business. The semiconductor industry is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. Companies in the semiconductor industry also may be subject to competition from new market entrants. The stock prices of companies in the semiconductor industry have been and will likely continue to be extremely volatile compared to the overall market.

Developed countries tend to represent a significant portion of the global economy and have generally experienced slower economic growth than some less developed countries. Certain developed countries have experienced security concerns, such as war, terrorism, and strained international relations. Incidents involving a country’s or region’s security may cause uncertainty in its markets and may adversely affect its economy and the Fund’s investments.

| Tema Analog Semiconductor ETF | Common Stock Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Common Stock Risk. Common stock holds the lowest priority in the capital structure of a company, and, therefore, takes the largest share of the company’s risk and its accompanying volatility. The value of the common stock held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or facts relating to specific companies in which the Fund invests.

| Tema Analog Semiconductor ETF | Currency Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Currency Risk. The Fund may invest its assets in securities denominated in non-U.S. currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of the shares. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of the non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the value of the Fund’s holdings, measured in the foreign currency, increases. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

| Risk [Text Block] | Cybersecurity and Disaster Recovery Risks. Information and technology systems relied upon by the Fund, the Adviser, the Fund’s other service providers (including, but not limited to, the Fund Accountant, Custodian, Transfer Agent, Administrator and Distributor), market makers, Authorized Participants, financial intermediaries and/or the issuers of securities in which the Fund invests may be vulnerable to damage or interruption from computer viruses, network failures, computer and telecommunication failures, infiltration by unauthorized persons, security breaches, usage errors, power outages and catastrophic events such as fires, tornadoes, floods, hurricanes and earthquakes. Although the Adviser and the Fund’s other service providers have implemented measures to manage risks relating to these types of events, if these systems are compromised, become inoperable for extended periods of time or cease to function properly, significant investment may be required to fix or replace them. The failure of these systems and/or of disaster recovery plans could cause significant interruptions in the operations of the Fund, the Adviser, the Fund’s other service providers, market makers, Authorized Participants, financial intermediaries and/or issuers of securities in which the Fund invests and may result in a failure to maintain the security, confidentiality or privacy of sensitive data, impact the Fund’s ability to calculate its NAV or impede trading.

| Tema Analog Semiconductor ETF | Depositary Receipt Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Depositary Receipt Risk. The Fund may invest in depositary receipts which involve similar risks to those associated with investments in foreign securities. Investments in depositary receipts may be less liquid than the underlying shares in their primary trading market.
ADRs and GDRs may be subject to some of the same risks as direct investment in foreign companies, which includes international trade, currency, political, regulatory and diplomatic risks. In a sponsored ADR or GDR arrangement, the foreign issuer assumes the obligation to pay some or all of the depositary’s transaction fees. Under an unsponsored ADR or GDR arrangement, the foreign issuer assumes no obligations and the depositary’s transaction fees are paid directly by the ADR or GDR holders. Because unsponsored ADR and GDR arrangements are organized independently and without the cooperation of the issuer of the underlying securities, available information concerning the foreign issuer may not be as current as for sponsored ADRs and GDRs and voting rights with respect to the deposited securities that are not passed through.

An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

| Tema Analog Semiconductor ETF | Etf Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | ETF Risk. The Fund is structured as an ETF. As a result, the Fund is subject to special risks, including:
Additionally, purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund’s NAV to the extent not offset by a transaction fee payable by an AP.

|||||||||||||||||||||
| Tema Analog Semiconductor ETF | Fluctuation Of Net Asset Value Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Fluctuation of Net Asset Value Risk. The NAV of the Fund’s shares will generally fluctuate with changes in the market value of the Fund’s holdings. The market prices of the shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of and demand for shares on [ ] (the “Exchange”). The Adviser cannot predict whether the shares will trade below, at or above their NAV. The Fund’s market price may deviate from the value of its underlying portfolio holdings, particularly in times of market stress, with the result that investors may pay significantly more or receive significantly less than the underlying value of the Fund shares bought or sold. This can be reflected as a spread between the bid and ask prices for the Fund quoted during the day or a premium or discount in the closing price from the Fund’s NAV. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material effect on the market price of the Fund’s shares.

| Risk [Text Block] | Foreign Securities Risk. Investments in securities (including ADRs and GDRs) of foreign issuers involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers. The values of foreign investments may be affected by changes in exchange control regulations, application of foreign tax laws (including withholding tax) changes in governmental administration or economic or monetary policy (in this country or abroad) or changed circumstances in dealings between nations. The value of foreign securities is also affected by the value of the local currency relative to the U.S. Dollar. GDRs may be other than dollar denominated and may be issued in several countries.

| Tema Analog Semiconductor ETF | Geographic Investment Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Geographic Investment Risk. To the extent the Fund is significantly comprised of securities of issuers from a single country, the Fund would be more likely to be impacted by events or conditions affecting that country.
Chinese Securities Risk. A portion of the Fund’s assets may be invested in companies exposed to China. Risks affecting investments in China include a potential downturn in the Chinese economy, reduced liquidity or increased price volatility in the Chinese securities markets as a result of trading suspensions affecting Chinese issuers or other factors, the potential that the Chinese government may expand restrictions on foreign investments or the repatriation of capital, and the implementation of new tariffs or other trade barriers by China or its trading partners. A lack of transparency respecting Chinese companies may also reduce the Fund’s ability to conduct diligence respecting those companies’ accounting and governance standards, which may in turn reduce the Fund’s ability to detect fraudulent practices that may adversely affect the companies’ stock prices.
European Securities Risk. The Fund is more exposed to the economic and political risks of Europe and of the European countries in which it invests than funds whose investments are more geographically diversified. Adverse economic and political events, including war, in Europe may cause the Fund’s investments to decline in value. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member states of the European Union (the “EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have historically experienced volatility and adverse trends and these events have and may in the future adversely affect the exchange rate of the euro and may significantly affect other European countries.
Japanese Securities Risk. Because a portion of the assets of the Fund may be invested in Japanese securities, the Fund’s performance may be tied to the political, social and economic conditions within Japan. The Japanese economy has at times in the past been negatively affected by government intervention and protectionism, a deflationary macroeconomic environment, a heavy reliance on international trade and natural disasters. These factors, as well as an aging population, increases in government debt and changes to fiscal, monetary, or trade policies, may affect Japanese markets and the Fund’s performance. As such, the Fund’s performance may be more volatile than the performance of funds that are more geographically diverse.
South Korean Securities Risk. Investments in South Korean issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to South Korea. In addition, economic and political developments of South Korea’s neighbors, including escalated tensions involving North Korea and any outbreak of hostilities involving North Korea, or even the threat of an outbreak of hostilities, may have a severe adverse effect on the South Korean economy.

Semiconductor Companies Risk. The Fund invests in companies primarily involved in the development, design, distribution, manufacture and sale of semiconductors. Semiconductor companies are significantly affected by rapid obsolescence, intense competition and global demand. The Fund is also subject to the risk that the securities of such issuers may underperform the market as a whole due to legislative or regulatory changes. The prices of securities of semiconductor companies may fluctuate widely in response to such events.

The securities of large-capitalization companies may also be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

| Tema Analog Semiconductor ETF | Market Risk And Selection Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Market Risk and Selection Risk. The prices of securities held by the Fund may decline in response to certain events taking place around the world, including those directly involving the companies whose securities are owned by the Fund; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency, interest rate and commodity price fluctuations. The equity securities purchased by the Fund may involve large price swings and potential for loss. Investors in the Fund should have a long-term perspective and be able to tolerate potentially sharp declines in value. The market’s daily movements, sometimes called volatility, may be greater or less depending on the types of securities the Fund owns and the markets in which the securities trade. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, climate change or climate related risks, natural disasters, pandemics, epidemics, war, terrorism, regulatory events, governmental or quasi-governmental actions, and public health emergencies. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets.

The micro-capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies, and may underperform other segments of the market or the equity market as a whole. Securities of micro-capitalization companies generally trade in lower volumes, are often more vulnerable to market volatility, and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole.

| Risk [Text Block] | National Closed Market Trading Risk. To the extent that securities or other assets held by the Fund trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between such asset’s current price and its last quoted price (i.e., the quote from the closed foreign market to the Fund). The impact of a closed foreign market on the Fund is likely to be greater where a large portion of the Fund’s holdings trade on a closed foreign market or when a foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other funds.

| Tema Analog Semiconductor ETF | New Fund Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | New Fund Risk. A new or smaller fund is subject to the risk that its performance may not represent how the fund is expected to or may perform in the long term. In addition, new funds have limited operating histories for investors to evaluate and new and smaller funds may not attract sufficient assets to achieve investment and trading efficiencies. There can be no assurance that the Fund will achieve an economically viable size. Further, an active trading market for shares of the Fund may not develop or be maintained.

The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third parties, failed or inadequate processes and technology or systems failures. The Fund seeks to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

|||||||||||||||||||||
| Tema Analog Semiconductor ETF | Privately Placed Securities Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Privately Placed Securities Risk. The Fund may invest in non-exchange traded securities, including privately placed securities, which are subject to liquidity and valuation risks. These risks may make it difficult for those securities to be traded or valued, especially in the event of adverse economic and liquidity conditions or adverse changes in the issuer’s financial condition. The market for certain non-exchange traded securities may be limited to institutional investors, subjecting such investments to further liquidity risk if a market were to limit institutional trading. There may also be less information available regarding such non-exchange traded securities than for publicly traded securities, which may make it more difficult for the Adviser to fully evaluate the risks of investing in such securities and as a result place the Fund’s assets at greater risk of loss than if the Adviser had more complete information. In addition, the issuers of non-exchange traded securities may be distressed, insolvent, or delinquent in filing information needed to be listed on an exchange. Disposing of nonexchange traded securities, including privately placed securities, may involve time-consuming negotiation and legal expenses, and selling them promptly at an acceptable price may be difficult or impossible. Securities purchased in private placements may be subject to legal or contractual restrictions on resale. The Fund may have to bear the expense of registering restricted securities for resale and the risk of substantial delay in effecting registration.
The Fund may have exposure to restricted securities. Restricted securities are securities with restrictions on public resale, such as securities offered in accordance with an exemption under Rule 144A under the Securities Act of 1933 (the “1933 Act”), or commercial paper issued under Section 4(a)(2) of the 1933 Act. Restricted securities are often required to be sold in private sales to institutional buyers, markets for restricted securities may or may not be well developed, and restricted securities can be illiquid. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions or other economic and market impediments. Funds with principal investment strategies that involve investments in securities of companies with smaller market capitalizations, foreign securities, derivatives, or securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk. Exposure to liquidity risk may be heightened for funds that invest in securities of emerging markets and related derivatives that are not widely traded, and that may be subject to purchase and sale restrictions.

| Tema Analog Semiconductor ETF | Proprietary Infrastructure Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Proprietary Infrastructure Risk. The success of the Fund’s investment strategy depends in part on the ability of the companies in which it invests to maintain proprietary technology used in their products and services. Companies in which the Fund invests will rely, in part, on patent, trade secret and trademark law to protect that technology, but competitors may misappropriate their intellectual property, and disputes as to ownership of intellectual property may arise. Consequently, companies in which the Fund invests may, from time to time, be required to institute litigation in order to enforce their patents, copyrights or other intellectual property rights, to protect their trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement. Such litigation could result in substantial costs and diversion of resources. Similarly, if a company is found to infringe upon or misappropriate a third-party’s patent or other proprietary rights, that company could be required to pay damages to such third-party, alter its own products or processes, obtain a license from the third-party and/or cease activities utilizing such proprietary rights, including making or selling products utilizing such proprietary rights.

The Fund may invest a significant portion of its assets in one or more sectors and thus will be more susceptible to the risks affecting those sectors than funds that have more diversified holdings across a number of sectors. The Fund anticipates that it may be subject to some or all of the risks described below.
Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on their profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of any of these rights may adversely affect the profitability of these companies or the Fund’s performance.

| Tema Analog Semiconductor ETF | Semiconductor Company Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Semiconductor Company Risk. Competitive pressures may have a significant effect on the financial condition of companies in the semiconductor industry. As product cycles shorten and manufacturing capacity increases, these companies may become increasingly subject to aggressive pricing, which hampers profitability. Semiconductor companies are vulnerable to wide fluctuations in securities prices due to rapid product obsolescence. Many semiconductor companies may not successfully introduce new products, develop and maintain a loyal customer base or achieve general market acceptance for their products, and failure to do so could have a material adverse effect on their business, results of operations and financial condition. Reduced demand for end-user products, underutilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductor industry. Semiconductor companies typically face high capital costs and these companies may need additional financing, which may be difficult to obtain. They also may be subject to risks relating to research and development costs and the availability and price of components. Moreover,
they may be heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. Some of the companies involved in the semiconductor sector are also engaged in other lines of business unrelated to the semiconductor business, and they may experience problems with these lines of business, which could adversely affect their operating results. The international operations of many semiconductor companies expose them to risks associated with instability and changes in economic and political conditions, foreign currency fluctuations, changes in foreign regulations, tariffs and trade disputes, competition from subsidized foreign competitors with lower production costs and other risks inherent to international business. The semiconductor industry is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. Companies in the semiconductor industry also may be subject to competition from new market entrants. The stock prices of companies in the semiconductor industry have been and will likely continue to be extremely volatile compared to the overall market.

| Risk [Text Block] | Artificial Intelligence Technology Risk. Companies in the artificial intelligence (“AI”) and technology industries typically have high research and capital expenditures and, as a result, their profitability can vary widely, if they are profitable at all. The space in which they are engaged is highly competitive and issuers’ products and services may become obsolete very quickly. These companies are heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. The issuers are also subject to legal, regulatory and political changes that may have a large impact on their profitability. A failure in an issuer’s product or even questions about the safety of the product could be devastating to the issuer, especially if it is the marquee product of the issuer.

Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of the shares. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of the non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the value of the Fund’s holdings, measured in the foreign currency, increases.

The failure of these systems and/or of disaster recovery plans could cause significant interruptions in the operations of the Fund, the Adviser, the Fund’s other service providers, market makers, Authorized Participants, financial intermediaries and/or issuers of securities in which the Fund invests and may result in a failure to maintain the security, confidentiality or privacy of sensitive data, impact the Fund’s ability to calculate its NAV or impede trading.

| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Depositary Receipt Risk. The Fund may invest in depositary receipts which involve similar risks to those associated with investments in foreign securities. Investments in depositary receipts may be less liquid than the underlying shares in their primary trading market.
ADRs and GDRs may be subject to some of the same risks as direct investment in foreign companies, which includes international trade, currency, political, regulatory and diplomatic risks. In a sponsored ADR or GDR arrangement, the foreign issuer assumes the obligation to pay some or all of the depositary’s transaction fees. Under an unsponsored ADR or GDR arrangement, the foreign issuer assumes no obligations and the depositary’s transaction fees are paid directly by the ADR or GDR holders. Because unsponsored ADR and GDR arrangements are organized independently and without the cooperation of the issuer of the underlying securities, available information concerning the foreign issuer may not be as current as for sponsored ADRs and GDRs and voting rights with respect to the deposited securities that are not passed through.

An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

| Risk [Text Block] | ETF Risk. The Fund is structured as an ETF. As a result, the Fund is subject to special risks, including:
Additionally, purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund’s NAV to the extent not offset by a transaction fee payable by an AP.

| Tema MLCC ETF | Fluctuation Of Net Asset Value Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Fluctuation of Net Asset Value Risk. The NAV of the Fund’s shares will generally fluctuate with changes in the market value of the Fund’s holdings. The market prices of the shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of and demand for shares on [ ] (the “Exchange”). The Adviser cannot predict whether the shares will trade below, at or above their NAV. The Fund’s market price may deviate from the value of its underlying portfolio holdings, particularly in times of market stress, with the result that investors may pay significantly more or receive significantly less than the underlying value of the Fund shares bought or sold. This can be reflected as a spread between the bid and ask prices for the Fund quoted during the day or a premium or discount in the closing price from the Fund’s NAV. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material effect on the market price of the Fund’s shares.

| Risk [Text Block] | Foreign Securities Risk. Investments in securities (including ADRs and GDRs) of foreign issuers involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers. The values of foreign investments may be affected by changes in exchange control regulations, application of foreign tax laws (including withholding tax) changes in governmental administration or economic or monetary policy (in this country or abroad) or changed circumstances in dealings between nations. The value of foreign securities is also affected by the value of the local currency relative to the U.S. Dollar. GDRs may be other than dollar denominated and may be issued in several countries.

| Tema MLCC ETF | Geographic Investment Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Geographic Investment Risk. To the extent the Fund is significantly comprised of securities of issuers from a single country, the Fund would be more likely to be impacted by events or conditions affecting that country.
Chinese Securities Risk. A portion of the Fund’s assets may be invested in companies exposed to China. Risks affecting investments in China include a potential downturn in the Chinese economy, reduced liquidity or increased price volatility in the Chinese securities markets as a result of trading suspensions affecting Chinese issuers or other factors, the potential that the Chinese government may expand restrictions on foreign investments or the repatriation of capital, and the implementation of new tariffs or other trade barriers by China or its trading partners. A lack of transparency respecting Chinese companies may also reduce the Fund’s ability to conduct diligence respecting those companies’ accounting and governance standards, which may in turn reduce the Fund’s ability to detect fraudulent practices that may adversely affect the companies’ stock prices.
European Securities Risk. The Fund is more exposed to the economic and political risks of Europe and of the European countries in which it invests than funds whose investments are more geographically diversified. Adverse economic and political events, including war, in Europe may cause the Fund’s investments to decline in value. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member states of the European Union (the “EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have historically experienced volatility and adverse trends and these events have and may in the future adversely affect the exchange rate of the euro and may significantly affect other European countries.
Japanese Securities Risk. Because a portion of the assets of the Fund may be invested in Japanese securities, the Fund’s performance may be tied to the political, social and economic conditions within Japan. The Japanese economy has at times in the past been negatively affected by government intervention and protectionism, a deflationary macroeconomic environment, a heavy reliance on international trade and natural disasters. These factors, as well as an aging population, increases in government debt and changes to fiscal, monetary, or trade policies, may affect Japanese markets and the Fund’s performance. As such, the Fund’s performance may be more volatile than the performance of funds that are more geographically diverse.
South Korean Securities Risk. Investments in South Korean issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to South Korea. In addition, economic and political developments of South Korea’s neighbors, including escalated tensions involving North Korea and any outbreak of hostilities involving North Korea, or even the threat of an outbreak of hostilities, may have a severe adverse effect on the South Korean economy.

The securities of large-capitalization companies may also be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

| Tema MLCC ETF | Market Risk And Selection Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Market Risk and Selection Risk. The prices of securities held by the Fund may decline in response to certain events taking place around the world, including those directly involving the companies whose securities are owned by the Fund; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency, interest rate and commodity price fluctuations. The equity securities purchased by the Fund may involve large price swings and potential for loss. Investors in the Fund should have a long-term perspective and be able to tolerate potentially sharp declines in value. The market’s daily movements, sometimes called volatility, may be greater or less depending on the types of securities the Fund owns and the markets in which the securities trade. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, climate change or climate related risks, natural disasters, pandemics, epidemics, war, terrorism, regulatory events, governmental or quasi-governmental actions, and public health emergencies. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets.

The micro-capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies, and may underperform other segments of the market or the equity market as a whole. Securities of micro-capitalization companies generally trade in lower volumes, are often more vulnerable to market volatility, and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole.

| Risk [Text Block] | National Closed Market Trading Risk. To the extent that securities or other assets held by the Fund trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between such asset’s current price and its last quoted price (i.e., the quote from the closed foreign market to the Fund). The impact of a closed foreign market on the Fund is likely to be greater where a large portion of the Fund’s holdings trade on a closed foreign market or when a foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other funds.

| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | New Fund Risk. A new or smaller fund is subject to the risk that its performance may not represent how the fund is expected to or may perform in the long term. In addition, new funds have limited operating histories for investors to evaluate and new and smaller funds may not attract sufficient assets to achieve investment and trading efficiencies. There can be no assurance that the Fund will achieve an economically viable size. Further, an active trading market for shares of the Fund may not develop or be maintained.

The Fund is a non-diversified investment company under the Investment Company Act of 1940 (the “1940 Act”), meaning that, as compared to a diversified fund, it can invest a greater percentage of its assets in securities issued by or representing a small number of issuers. As a result, the performance of these issuers can have a substantial impact on the Fund’s performance.

The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third parties, failed or inadequate processes and technology or systems failures. The Fund seeks to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

|||||||||||||||||||||
| Tema MLCC ETF | Privately Placed Securities Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Privately Placed Securities Risk. The Fund may invest in non-exchange traded securities, including privately placed securities, which are subject to liquidity and valuation risks. These risks may make it difficult for those securities to be traded or valued, especially in the event of adverse economic and liquidity conditions or adverse changes in the issuer’s financial condition. The market for certain non-exchange traded securities may be limited to institutional investors, subjecting such investments to further liquidity risk if a market were to limit institutional trading. There may also be less information available regarding such non-exchange traded securities than for publicly traded securities, which may make it more difficult for the Adviser to fully evaluate the risks of investing in such securities and as a result place the Fund’s assets at greater risk of loss than if the Adviser had more complete information. In addition, the issuers of non-exchange traded securities may be distressed, insolvent, or delinquent in filing information needed to be listed on an exchange. Disposing of nonexchange traded securities, including privately placed securities, may involve time-consuming negotiation and legal expenses, and selling them promptly at an acceptable price may be difficult or impossible. Securities purchased in private placements may be subject to legal or contractual restrictions on resale. The Fund may have to bear the expense of registering restricted securities for resale and the risk of substantial delay in effecting registration.
The Fund may have exposure to restricted securities. Restricted securities are securities with restrictions on public resale, such as securities offered in accordance with an exemption under Rule 144A under the Securities Act of 1933 (the “1933 Act”), or commercial paper issued under Section 4(a)(2) of the 1933 Act. Restricted securities are often required to be sold in private sales to institutional buyers, markets for restricted securities may or may not be well developed, and restricted securities can be illiquid. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions or other economic and market impediments. Funds with principal investment strategies that involve investments in securities of companies with smaller market capitalizations, foreign securities, derivatives, or securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk. Exposure to liquidity risk may be heightened for funds that invest in securities of emerging markets and related derivatives that are not widely traded, and that may be subject to purchase and sale restrictions.

| Tema MLCC ETF | Proprietary Infrastructure Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Proprietary Infrastructure Risk. The success of the Fund’s investment strategy depends in part on the ability of the companies in which it invests to maintain proprietary technology used in their products and services. Companies in which the Fund invests will rely, in part, on patent, trade secret and trademark law to protect that technology, but competitors may misappropriate their intellectual property, and disputes as to ownership of intellectual property may arise. Consequently, companies in which the Fund invests may, from time to time, be required to institute litigation in order to enforce their patents, copyrights or other intellectual property rights, to protect their trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement. Such litigation could result in substantial costs and diversion of resources. Similarly, if a company is found to infringe upon or misappropriate a third-party’s patent or other proprietary rights, that company could be required to pay damages to such third-party, alter its own products or processes, obtain a license from the third-party and/or cease activities utilizing such proprietary rights, including making or selling products utilizing such proprietary rights.

The Fund anticipates that it may be subject to some or all of the risks described below.
Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on their profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of any of these rights may adversely affect the profitability of these companies or the Fund’s performance.

| Tema MLCC ETF | Semiconductor Company Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Semiconductor Company Risk. Competitive pressures may have a significant effect on the financial condition of companies in the semiconductor industry. As product cycles shorten and manufacturing capacity increases, these companies may become increasingly subject to aggressive pricing, which hampers profitability. Semiconductor companies are vulnerable to wide fluctuations in securities prices due to rapid product obsolescence. Many semiconductor companies may not successfully introduce new products, develop and maintain a loyal customer base or achieve general market acceptance for their products, and failure to do so could have a material adverse effect on their business, results of operations and financial condition. Reduced demand for end-user products, underutilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductor industry. Semiconductor companies typically face high capital costs and these companies may need additional financing, which may be difficult to obtain. They also may be subject to risks relating to research and development costs and the availability and price of components. Moreover, they may be heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. Some of the companies involved in the semiconductor sector are also engaged in other lines of business unrelated to the semiconductor business, and they may experience problems with these lines of business, which could adversely affect their operating results. The international operations of many semiconductor companies expose them to risks associated with instability and changes in economic and political conditions, foreign currency fluctuations, changes in foreign regulations, tariffs and trade disputes, competition from subsidized foreign competitors with lower production costs and other risks inherent to international business. The semiconductor industry is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. Companies in the semiconductor industry also may be subject to competition from new market entrants. The stock prices of companies in the semiconductor industry have been and will likely continue to be extremely volatile compared to the overall market.

| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Multilayer Ceramic Capacitor (MLCC) Company Risk. MLCC companies may be subject to rapid changes in technology, intense competition, government regulation, and obsolescence risk. Securities of such companies may be subject to greater price volatility than securities of companies in other sectors, particularly over the short term. The prices of securities of MLCC companies may fluctuate widely due to competitive pressures, cyclical demand patterns, changes in the regulatory environment, and shifts in supply and demand dynamics. Many MLCC companies operate in capital-intensive manufacturing segments that require significant ongoing investment in production capacity, advanced materials, and process technology, making them particularly sensitive to fluctuations in end-market demand and capacity utilization rates. The technologies in which these companies are engaged are subject to continuous evolution, including miniaturization requirements, higher layer counts, tighter tolerances, and increasingly complex substrate architectures, and there is no guarantee that any particular manufacturing process, materials platform, or packaging technology will maintain its competitive position or prove commercially viable over the long term. MLCC companies may also be dependent upon a limited number of large customers, particularly original equipment manufacturers and contract electronics manufacturers, and the loss of, or a significant reduction in orders from, any such customer could have a disproportionate impact on revenues. Additionally, the growth and profitability of MLCC companies may be contingent upon the broader adoption of artificial intelligence, high-performance computing, 5G and advanced telecommunications infrastructure, electric vehicles, and advanced semiconductor packaging technologies. A slowdown or disruption in the growth of these related sectors, or a shift in industry standards, supply chain configurations, or trade policies—including tariffs, export controls, or restrictions on the sourcing of critical raw materials—could materially and adversely affect the revenues and profitability of MLCC companies in which the Fund invests.

| Risk [Text Block] | Artificial Intelligence Technology Risk. Companies in the artificial intelligence (“AI”) and technology industries typically have high research and capital expenditures and, as a result, their profitability can vary widely, if they are profitable at all. The space in which they are engaged is highly competitive and issuers’ products and services may become obsolete very quickly. These companies are heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. The issuers are also subject to legal, regulatory and political changes that may have a large impact on their profitability. A failure in an issuer’s product or even questions about the safety of the product could be devastating to the issuer, especially if it is the marquee product of the issuer. It can be difficult to accurately capture what qualifies as an AI and Technology company.

Common stock holds the lowest priority in the capital structure of a company, and, therefore, takes the largest share of the company’s risk and its accompanying volatility.

Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of the shares. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of the non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the value of the Fund’s holdings, measured in the foreign currency, increases. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

In a sponsored ADR or GDR arrangement, the foreign issuer assumes the obligation to pay some or all of the depositary’s transaction fees. Under an unsponsored ADR or GDR arrangement, the foreign issuer assumes no obligations and the depositary’s transaction fees are paid directly by the ADR or GDR holders. Because unsponsored ADR and GDR arrangements are organized independently and without the cooperation of the issuer of the underlying securities, available information concerning the foreign issuer may not be as current as for sponsored ADRs and GDRs and voting rights with respect to the deposited securities that are not passed through.

An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

| Risk [Text Block] | ETF Risk. The Fund is structured as an ETF. As a result, the Fund is subject to special risks, including:
Additionally, purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund’s NAV to the extent not offset by a transaction fee payable by an AP.

| Tema Physical AI ETF | Fluctuation Of Net Asset Value Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Fluctuation of Net Asset Value Risk. The NAV of the Fund’s shares will generally fluctuate with changes in the market value of the Fund’s holdings. The market prices of the shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of and demand for shares on [ ] (the “Exchange”). The Adviser cannot predict whether the shares will trade below, at or above their NAV. The Fund’s market price may deviate from the value of its underlying portfolio holdings, particularly in times of market stress, with the result that investors may pay significantly more or receive significantly less than the underlying value of the Fund shares bought or sold. This can be reflected as a spread between the bid and ask prices for the Fund quoted during the day or a premium or discount in the closing price from the Fund’s NAV. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material effect on the market price of the Fund’s shares.

| Risk [Text Block] | Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Foreign Securities Risk. Investments in securities (including ADRs and GDRs) of foreign issuers involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers. The values of foreign investments may be affected by changes in exchange control regulations, application of foreign tax laws (including withholding tax) changes in governmental administration or economic or monetary policy (in this country or abroad) or changed circumstances in dealings between nations. The value of foreign securities is also affected by the value of the local currency relative to the U.S. Dollar. GDRs may be other than dollar denominated and may be issued in several countries.

| Tema Physical AI ETF | Geographic Investment Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Geographic Investment Risk. To the extent the Fund is significantly comprised of securities of issuers from a single country, the Fund would be more likely to be impacted by events or conditions affecting that country.
Chinese Securities Risk. A portion of the Fund’s assets may be invested in companies exposed to China. Risks affecting investments in China include a potential downturn in the Chinese economy, reduced liquidity or increased price volatility in the Chinese securities markets as a result of trading suspensions affecting Chinese issuers or other factors, the potential that the Chinese government may expand restrictions on foreign investments or the repatriation of capital, and the implementation of new tariffs or other trade barriers by China or its trading partners. A lack of transparency respecting Chinese companies may also reduce the Fund’s ability to conduct diligence respecting those companies’ accounting and governance standards, which may in turn reduce the Fund’s ability to detect fraudulent practices that may adversely affect the companies’ stock prices.
European Securities Risk. The Fund is more exposed to the economic and political risks of Europe and of the European countries in which it invests than funds whose investments are more geographically diversified. Adverse economic and political events, including war, in Europe may cause the Fund’s investments to decline in value. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member states of the European Union (the “EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have historically experienced volatility and adverse trends and these events have and may in the future adversely affect the exchange rate of the euro and may significantly affect other European countries.
Japanese Securities Risk. Because a portion of the assets of the Fund may be invested in Japanese securities, the Fund’s performance may be tied to the political, social and economic conditions within Japan. The Japanese economy has at times in the past been negatively affected by government intervention and protectionism, a deflationary macroeconomic environment, a heavy reliance on international trade and natural disasters. These factors, as well as an aging population, increases in government debt and changes to fiscal, monetary, or trade policies, may affect Japanese markets and the Fund’s performance. As such, the Fund’s performance may be more volatile than the performance of funds that are more geographically diverse.
South Korean Securities Risk. Investments in South Korean issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to South Korea. In addition, economic and political developments of South Korea’s neighbors, including escalated tensions involving North Korea and any outbreak of hostilities involving North Korea, or even the threat of an outbreak of hostilities, may have a severe adverse effect on the South Korean economy.

| Tema Physical AI ETF | Industry Concentration Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Industry Concentration Risk. Because the Fund’s assets will be concentrated in an industry or group of industries, the Fund is subject to loss due to adverse occurrences that may affect that industry or group of industries.
AI Companies Risk. AI companies may be characterized by concentrated product offerings, limited market reach, constrained financial resources, or restricted personnel capacity. The securities of such companies may exhibit greater price volatility relative to securities of companies that rely less on technology. The accelerated pace of technological evolution affecting a company’s product portfolio may exert materially adverse effects on its operating performance. Companies operating within the AI sector rely substantially upon a framework of intellectual property protections, including patents, copyrights, trademarks, and trade secret laws, to establish and maintain proprietary rights in their products and technological innovations. No assurance can be provided that protective measures implemented by such companies will prove sufficient to prevent misappropriation of their technology, nor that competitors will not independently develop substantially equivalent or superior technologies. AI companies typically allocate significant capital expenditures toward research and development initiatives. However, there is no guarantee that products or services resulting from such investments will achieve commercial viability or success.

The securities of large-capitalization companies may also be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

| Tema Physical AI ETF | Market Risk And Selection Risk [Member] | ||||||||||||||||||||||

| Risk [Text Block] | Market Risk and Selection Risk. The prices of securities held by the Fund may decline in response to certain events taking place around the world, including those directly involving the companies whose securities are owned by the Fund; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency, interest rate and commodity price fluctuations. The equity securities purchased by the Fund may involve large price swings and potential for loss. Investors in the Fund should have a long-term perspective and be able to tolerate potentially sharp declines in value. The market’s daily movements, sometimes called volatility, may be greater or less depending on the types of securities the Fund owns and the markets in which the securities trade. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, climate change or climate related risks, natural disasters, pandemics, epidemics, war, terrorism, regulatory events, governmental or quasi-governmental actions, and public health emergencies. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets.

| Risk [Text Block] | National Closed Market Trading Risk. To the extent that securities or other assets held by the Fund trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between such asset’s current price and its last quoted price (i.e., the quote from the closed foreign market to the Fund). The impact of a closed foreign market on the Fund is likely to be greater where a large portion of the Fund’s holdings trade on a closed foreign market or when a foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other funds.

| Risk [Text Block] | New Fund Risk. A new or smaller fund is subject to the risk that its performance may not represent how the fund is expected to or may perform in the long term. In addition, new funds have limited operating histories for investors to evaluate and new and smaller funds may not attract sufficient assets to achieve investment and trading efficiencies. There can be no assurance that the Fund will achieve an economically viable size. Further, an active trading market for shares of the Fund may not develop or be maintained.

The Fund is a non-diversified investment company under the Investment Company Act of 1940 (the “1940 Act”), meaning that, as compared to a diversified fund, it can invest a greater percentage of its assets in securities issued by or representing a small number of issuers.

The Fund seeks to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

| Tema Physical AI ETF | Privately Placed Securities Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Privately Placed Securities Risk. The Fund may invest in non-exchange traded securities, including privately placed securities, which are subject to liquidity and valuation risks. These risks may make it difficult for those securities to be traded or valued, especially in the event of adverse economic and liquidity conditions or adverse changes in the issuer’s financial condition. The market for certain non-exchange traded securities may be limited to institutional investors, subjecting such investments to further liquidity risk if a market were to limit institutional trading. There may also be less information available regarding such non-exchange traded securities than for publicly traded securities, which may make it more difficult for the Adviser to fully evaluate the risks of investing in such securities and as a result place the Fund’s assets at greater risk of loss than if the Adviser had more complete information. In addition, the issuers of non-exchange traded securities may be distressed, insolvent, or delinquent in filing information needed to be listed on an exchange. Disposing of nonexchange traded securities, including privately placed securities, may involve time-consuming negotiation and legal expenses, and selling them promptly at an acceptable price may be difficult or impossible. Securities purchased in private placements may be subject to legal or contractual restrictions on resale. The Fund may have to bear the expense of registering restricted securities for resale and the risk of substantial delay in effecting registration.
The Fund may have exposure to restricted securities. Restricted securities are securities with restrictions on public resale, such as securities offered in accordance with an exemption under Rule 144A under the Securities Act of 1933 (the “1933 Act”), or commercial paper issued under Section 4(a)(2) of the 1933 Act. Restricted securities are often required to be sold in private sales to institutional buyers, markets for restricted securities may or may not be well developed, and restricted securities can be illiquid. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions or other economic and market impediments. Funds with principal investment strategies that involve investments in securities of companies with smaller market capitalizations, foreign securities, derivatives, or securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk. Exposure to liquidity risk may be heightened for funds that invest in securities of emerging markets and related derivatives that are not widely traded, and that may be subject to purchase and sale restrictions.

| Tema Physical AI ETF | Proprietary Infrastructure Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Proprietary Infrastructure Risk. The success of the Fund’s investment strategy depends in part on the ability of the companies in which it invests to maintain proprietary technology used in their products and services. Companies in which the Fund invests will rely, in part, on patent, trade secret and trademark law to protect that technology, but competitors may misappropriate their intellectual property, and disputes as to ownership of intellectual property may arise. Consequently, companies in which the Fund invests may, from time to time, be required to institute litigation in order to enforce their patents, copyrights or other intellectual property rights, to protect their trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement. Such litigation could result in substantial costs and diversion of resources. Similarly, if a company is found to infringe upon or misappropriate a third-party’s patent or other proprietary rights, that company could be required to pay damages to such third-party, alter its own products or processes, obtain a license from the third-party and/or cease activities utilizing such proprietary rights, including making or selling products utilizing such proprietary rights.

The Fund may invest a significant portion of its assets in one or more sectors and thus will be more susceptible to the risks affecting those sectors than funds that have more diversified holdings across a number of sectors. The Fund anticipates that it may be subject to some or all of the risks described below.
Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on their profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of any of these rights may adversely affect the profitability of these companies or the Fund’s performance.

| Tema Semicap ETF | Artificial Intelligence Technology Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Artificial Intelligence Technology Risk. Companies in the artificial intelligence (“AI”) and technology industries typically have high research and capital expenditures and, as a result, their profitability can vary widely, if they are profitable at all. The space in which they are engaged is highly competitive and issuers’ products and services may become obsolete very quickly. These companies are heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. The issuers are also subject to legal, regulatory and political changes that may have a large impact on their profitability. A failure in an issuer’s product or even questions about the safety of the product could be devastating to the issuer, especially if it is the marquee product of the issuer. It can be difficult to accurately capture what qualifies as an AI and Technology company.

The Fund has a limited number of institutions that act as Authorized Participants. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may trade at a discount to net asset value per share (“NAV”) and possibly face trading halts and/or delisting.

| Tema Semicap ETF | Common Stock Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Common Stock Risk. Common stock holds the lowest priority in the capital structure of a company, and, therefore, takes the largest share of the company’s risk and its accompanying volatility. The value of the common stock held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or facts relating to specific companies in which the Fund invests.

| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Currency Risk. The Fund may invest its assets in securities denominated in non-U.S. currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of the shares. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of the non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the value of the Fund’s holdings, measured in the foreign currency, increases. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

Although the Adviser and the Fund’s other service providers have implemented measures to manage risks relating to these types of events, if these systems are compromised, become inoperable for extended periods of time or cease to function properly, significant investment may be required to fix or replace them. The failure of these systems and/or of disaster recovery plans could cause significant interruptions in the operations of the Fund, the Adviser, the Fund’s other service providers, market makers, Authorized Participants, financial intermediaries and/or issuers of securities in which the Fund invests and may result in a failure to maintain the security, confidentiality or privacy of sensitive data, impact the Fund’s ability to calculate its NAV or impede trading.

Under an unsponsored ADR or GDR arrangement, the foreign issuer assumes no obligations and the depositary’s transaction fees are paid directly by the ADR or GDR holders.

The market prices of the shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of and demand for shares on [ ] (the “Exchange”). The Adviser cannot predict whether the shares will trade below, at or above their NAV. The Fund’s market price may deviate from the value of its underlying portfolio holdings, particularly in times of market stress, with the result that investors may pay significantly more or receive significantly less than the underlying value of the Fund shares bought or sold. This can be reflected as a spread between the bid and ask prices for the Fund quoted during the day or a premium or discount in the closing price from the Fund’s NAV. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material effect on the market price of the Fund’s shares.

| Tema Semicap ETF | Foreign Securities Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Foreign Securities Risk. Investments in securities (including ADRs and GDRs) of foreign issuers involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers. The values of foreign investments may be affected by changes in exchange control regulations, application of foreign tax laws (including withholding tax) changes in governmental administration or economic or monetary policy (in this country or abroad) or changed circumstances in dealings between nations. The value of foreign securities is also affected by the value of the local currency relative to the U.S. Dollar. GDRs may be other than dollar denominated and may be issued in several countries.

| Tema Semicap ETF | Geographic Investment Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Geographic Investment Risk. To the extent the Fund is significantly comprised of securities of issuers from a single country, the Fund would be more likely to be impacted by events or conditions affecting that country.
Chinese Securities Risk. A portion of the Fund’s assets may be invested in companies exposed to China. Risks affecting investments in China include a potential downturn in the Chinese economy, reduced liquidity or increased price volatility in the Chinese securities markets as a result of trading suspensions affecting Chinese issuers or other factors, the potential that the Chinese government may expand restrictions on foreign investments or the repatriation of capital, and the implementation of new tariffs or other trade barriers by China or its trading partners. A lack of transparency respecting Chinese companies may also reduce the Fund’s ability to conduct diligence respecting those companies’ accounting and governance standards, which may in turn reduce the Fund’s ability to detect fraudulent practices that may adversely affect the companies’ stock prices.
European Securities Risk. The Fund is more exposed to the economic and political risks of Europe and of the European countries in which it invests than funds whose investments are more geographically diversified. Adverse economic and political events, including war, in Europe may cause the Fund’s investments to decline in value. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member states of the European Union (the “EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have historically experienced volatility and adverse trends and these events have and may in the future adversely affect the exchange rate of the euro and may significantly affect other European countries.
Japanese Securities Risk. Because a portion of the assets of the Fund may be invested in Japanese securities, the Fund’s performance may be tied to the political, social and economic conditions within Japan. The Japanese economy has at times in the past been negatively affected by government intervention and protectionism, a deflationary macroeconomic environment, a heavy reliance on international trade and natural disasters. These factors, as well as an aging population, increases in government debt and changes to fiscal, monetary, or trade policies, may affect Japanese markets and the Fund’s performance. As such, the Fund’s performance may be more volatile than the performance of funds that are more geographically diverse.
South Korean Securities Risk. Investments in South Korean issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to South Korea. In addition, economic and political developments of South Korea’s neighbors, including escalated tensions involving North Korea and any outbreak of hostilities involving North Korea, or even the threat of an outbreak of hostilities, may have a severe adverse effect on the South Korean economy.

| Tema Semicap ETF | Industry Concentration Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Industry Concentration Risk. Because the Fund’s assets will be concentrated in an industry or group of industries, the Fund is subject to loss due to adverse occurrences that may affect that industry or group of industries.
Semicap Company Risk. Semiconductor Capital Equipment (semicap) companies build and manufacture the machinery, tools, and materials used to manufacture microchips. While they offer heavy exposure to AI infrastructure and digital tech, their prospectuses warn of high industry cyclicality, supply chain bottlenecks, and severe geographic/issuer concentration.
Semiconductor Companies Risk. The Fund invests in companies primarily involved in the development, design, distribution, manufacture and sale of semiconductors. Semiconductor companies are significantly affected by rapid obsolescence, intense competition and global demand. The Fund is also subject to the risk that the securities of such issuers may underperform the market as a whole due to legislative or regulatory changes. The prices of securities of semiconductor companies may fluctuate widely in response to such events.

| Tema Semicap ETF | Largecapitalization Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Large-Capitalization Risk. Returns on investments in securities of large companies could trail the returns on investments in securities of smaller and mid-sized companies. The securities of large-capitalization companies may also be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
|
|||||||||||||||||||||
| Tema Semicap ETF | Market Risk And Selection Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Market Risk and Selection Risk. The prices of securities held by the Fund may decline in response to certain events taking place around the world, including those directly involving the companies whose securities are owned by the Fund; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency, interest rate and commodity price fluctuations. The equity securities purchased by the Fund may involve large price swings and potential for loss. Investors in the Fund should have a long-term perspective and be able to tolerate potentially sharp declines in value. The market’s daily movements, sometimes called volatility, may be greater or less depending on the types of securities the Fund owns and the markets in which the securities trade. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, climate change or climate related risks, natural disasters, pandemics, epidemics, war, terrorism, regulatory events, governmental or quasi-governmental actions, and public health emergencies. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets.

| Risk [Text Block] | Micro-Capitalization Risk. The micro-capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies, and may underperform other segments of the market or the equity market as a whole. Securities of micro-capitalization companies generally trade in lower volumes, are often more vulnerable to market volatility, and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole.

| Tema Semicap ETF | National Closed Market Trading Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | National Closed Market Trading Risk. To the extent that securities or other assets held by the Fund trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between such asset’s current price and its last quoted price (i.e., the quote from the closed foreign market to the Fund). The impact of a closed foreign market on the Fund is likely to be greater where a large portion of the Fund’s holdings trade on a closed foreign market or when a foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other funds.
|
|||||||||||||||||||||
| Tema Semicap ETF | New Fund Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | New Fund Risk. A new or smaller fund is subject to the risk that its performance may not represent how the fund is expected to or may perform in the long term. In addition, new funds have limited operating histories for investors to evaluate and new and smaller funds may not attract sufficient assets to achieve investment and trading efficiencies. There can be no assurance that the Fund will achieve an economically viable size. Further, an active trading market for shares of the Fund may not develop or be maintained.

| Tema Semicap ETF | Nondiversified Fund Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Non-Diversified Fund Risk. The Fund is a non-diversified investment company under the Investment Company Act of 1940 (the “1940 Act”), meaning that, as compared to a diversified fund, it can invest a greater percentage of its assets in securities issued by or representing a small number of issuers. As a result, the performance of these issuers can have a substantial impact on the Fund’s performance.

|||||||||||||||||||||
| Tema Semicap ETF | Operational Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third parties, failed or inadequate processes and technology or systems failures. The Fund seeks to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.
|
|||||||||||||||||||||
| Tema Semicap ETF | Privately Placed Securities Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Privately Placed Securities Risk. The Fund may invest in non-exchange traded securities, including privately placed securities, which are subject to liquidity and valuation risks. These risks may make it difficult for those securities to be traded or valued, especially in the event of adverse economic and liquidity conditions or adverse changes in the issuer’s financial condition. The market for certain non-exchange traded securities may be limited to institutional investors, subjecting such investments to further liquidity risk if a market were to limit institutional trading. There may also be less information available
regarding such non-exchange traded securities than for publicly traded securities, which may make it more difficult for the Adviser to fully evaluate the risks of investing in such securities and as a result place the Fund’s assets at greater risk of loss than if the Adviser had more complete information. In addition, the issuers of non-exchange traded securities may be distressed, insolvent, or delinquent in filing information needed to be listed on an exchange. Disposing of nonexchange traded securities, including privately placed securities, may involve time-consuming negotiation and legal expenses, and selling them promptly at an acceptable price may be difficult or impossible. Securities purchased in private placements may be subject to legal or contractual restrictions on resale. The Fund may have to bear the expense of registering restricted securities for resale and the risk of substantial delay in effecting registration.
The Fund may have exposure to restricted securities. Restricted securities are securities with restrictions on public resale, such as securities offered in accordance with an exemption under Rule 144A under the Securities Act of 1933 (the “1933 Act”), or commercial paper issued under Section 4(a)(2) of the 1933 Act. Restricted securities are often required to be sold in private sales to institutional buyers, markets for restricted securities may or may not be well developed, and restricted securities can be illiquid. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions or other economic and market impediments. Funds with principal investment strategies that involve investments in securities of companies with smaller market capitalizations, foreign securities, derivatives, or securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk. Exposure to liquidity risk may be heightened for funds that invest in securities of emerging markets and related derivatives that are not widely traded, and that may be subject to purchase and sale restrictions.

| Tema Semicap ETF | Proprietary Infrastructure Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Proprietary Infrastructure Risk. The success of the Fund’s investment strategy depends in part on the ability of the companies in which it invests to maintain proprietary technology used in their products and services. Companies in which the Fund invests will rely, in part, on patent, trade secret and trademark law to protect that technology, but competitors may misappropriate their intellectual property, and disputes as to ownership of intellectual property may arise. Consequently, companies in which the Fund invests may, from time to time, be required to institute litigation in order to enforce their patents, copyrights or other intellectual property rights, to protect their trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement. Such litigation could result in substantial costs and diversion of resources. Similarly, if a company is found to infringe upon or misappropriate a third-party’s patent or other proprietary rights, that company could be required to pay damages to such third-party, alter its own products or processes, obtain a license from the third-party and/or cease activities utilizing such proprietary rights, including making or selling products utilizing such proprietary rights.

| Risk [Text Block] | Sector Focus Risk. The Fund may invest a significant portion of its assets in one or more sectors and thus will be more susceptible to the risks affecting those sectors than funds that have more diversified holdings across a number of sectors. The Fund anticipates that it may be subject to some or all of the risks described below.
Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on their profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of any of these rights may adversely affect the profitability of these companies or the Fund’s performance.

Although the Fund will receive collateral in connection with all loans of its securities holdings, the Fund would be exposed to a risk of loss should a borrower default on its obligation to return the borrowed securities (e.g., the loaned securities may have appreciated beyond the value of the collateral held by the Fund). In addition, the Fund will bear the risk of loss of any cash collateral that it invests.

Value investing is subject to the risk that the market will not recognize a security’s inherent value for a long time or at all, or that a stock judged to be undervalued may actually be appropriately priced or overvalued. In addition, during some periods (which may be extensive), value stocks generally may be out of favor in the markets. |

| Tema Semicap ETF | Developed Country Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Developed Country Risk. The Fund’s investments in developed country issuers subject the Fund to legal, regulatory, political, currency, security, economic, and other risks associated with developed countries. Developed countries tend to represent a significant portion of the global economy and have generally experienced slower economic growth than some less developed countries. Certain developed countries have experienced security concerns, such as war, terrorism, and strained international relations. Incidents involving a country’s or region’s security may cause uncertainty in its markets and may adversely affect its economy and the Fund’s investments. In addition, developed countries may be adversely impacted by changes in the economic conditions of key trading partners, regulatory burdens, debt levels, and the price or availability of certain commodities.

| Risk [Text Block] | Actively Managed Risk. The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns, which may cause the Fund to fail to meet its investment objective or to underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active trading that can accompany active management may result in high portfolio turnover, which may have a negative impact on performance. Active trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund. Active trading may also result in adverse tax consequences.

| Tema Semiconductor Manufacturing ETF | Artificial Intelligence Technology Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Artificial Intelligence Technology Risk. Companies in the artificial intelligence (“AI”) and technology industries typically have high research and capital expenditures and, as a result, their profitability can vary widely, if they are profitable at all. The space in which they are engaged is highly competitive and issuers’ products and services may become obsolete very quickly. These companies are heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. The issuers are also subject to legal, regulatory and political changes that may have a large impact on their profitability. A failure in an issuer’s product or even questions about the safety of the product could be devastating to the issuer, especially if it is the marquee product of the issuer. It can be difficult to accurately capture what qualifies as an AI and Technology company.

| Risk [Text Block] | Authorized Participant Concentration Risk. Only an Authorized Participant (as defined below) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that act as Authorized Participants. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may trade at a discount to net asset value per share (“NAV”) and possibly face trading halts and/or delisting.

| Tema Semiconductor Manufacturing ETF | Common Stock Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Common Stock Risk. Common stock holds the lowest priority in the capital structure of a company, and, therefore, takes the largest share of the company’s risk and its accompanying volatility. The value of the common stock held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or facts relating to specific companies in which the Fund invests.

| Tema Semiconductor Manufacturing ETF | Currency Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Currency Risk. The Fund may invest its assets in securities denominated in non-U.S. currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of the shares. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of the non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the value of the Fund’s holdings, measured in the foreign currency, increases. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

Information and technology systems relied upon by the Fund, the Adviser, the Fund’s other service providers (including, but not limited to, the Fund Accountant, Custodian, Transfer Agent, Administrator and Distributor), market makers, Authorized Participants, financial intermediaries and/or the issuers of securities in which the Fund invests may be vulnerable to damage or interruption from computer viruses, network failures, computer and telecommunication failures, infiltration by unauthorized persons, security breaches, usage errors, power outages and catastrophic events such as fires, tornadoes, floods, hurricanes and earthquakes. Although the Adviser and the Fund’s other service providers have implemented measures to manage risks relating to these types of events, if these systems are compromised, become inoperable for extended periods of time or cease to function properly, significant investment may be required to fix or replace them. The failure of these systems and/or of disaster recovery plans could cause significant interruptions in the operations of the Fund, the Adviser, the Fund’s other service providers, market makers, Authorized Participants, financial intermediaries and/or issuers of securities in which the Fund invests and may result in a failure to maintain the security, confidentiality or privacy of sensitive data, impact the Fund’s ability to calculate its NAV or impede trading.

| Tema Semiconductor Manufacturing ETF | Depositary Receipt Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Depositary Receipt Risk. The Fund may invest in depositary receipts which involve similar risks to those associated with investments in foreign securities. Investments in depositary receipts may be less liquid than the underlying shares in their primary trading market.
ADRs and GDRs may be subject to some of the same risks as direct investment in foreign companies, which includes international trade, currency, political, regulatory and diplomatic risks. In a sponsored ADR or GDR arrangement, the foreign issuer assumes the obligation to pay some or all of the depositary’s transaction fees. Under an unsponsored ADR or GDR arrangement, the foreign issuer assumes no obligations and the depositary’s transaction fees are paid directly by the ADR or GDR holders. Because unsponsored ADR and GDR arrangements are organized independently and without the cooperation of the issuer of the underlying securities, available information concerning the foreign issuer may not be as current as for sponsored ADRs and GDRs and voting rights with respect to the deposited securities that are not passed through.

| Risk [Text Block] | ETF Risk. The Fund is structured as an ETF. As a result, the Fund is subject to special risks, including:
Additionally, purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund’s NAV to the extent not offset by a transaction fee payable by an AP.

|||||||||||||||||||||
| Tema Semiconductor Manufacturing ETF | Fluctuation Of Net Asset Value Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Fluctuation of Net Asset Value Risk. The NAV of the Fund’s shares will generally fluctuate with changes in the market value of the Fund’s holdings. The market prices of the shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of and demand for shares on [ ] (the “Exchange”). The Adviser cannot predict whether the shares will trade below, at or above their NAV. The Fund’s market price may deviate from the value of its underlying portfolio holdings, particularly in times of market stress, with the result that investors may pay significantly more or receive significantly less than the underlying value of the Fund shares bought or sold. This can be reflected as a spread between the bid and ask prices for the Fund quoted during the day or a premium or discount in the closing price from the Fund’s NAV. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material effect on the market price of the Fund’s shares.

| Risk [Text Block] | Foreign Securities Risk. Investments in securities (including ADRs and GDRs) of foreign issuers involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers. The values of foreign investments may be affected by changes in exchange control regulations, application of foreign tax laws (including withholding tax) changes in governmental administration or economic or monetary policy (in this country or abroad) or changed circumstances in dealings between nations. The value of foreign securities is also affected by the value of the local currency relative to the U.S. Dollar. GDRs may be other than dollar denominated and may be issued in several countries.

| Tema Semiconductor Manufacturing ETF | Geographic Investment Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Geographic Investment Risk. To the extent the Fund is significantly comprised of securities of issuers from a single country, the Fund would be more likely to be impacted by events or conditions affecting that country.
Chinese Securities Risk. A portion of the Fund’s assets may be invested in companies exposed to China. Risks affecting investments in China include a potential downturn in the Chinese economy, reduced liquidity or increased price volatility in the Chinese securities markets as a result of trading suspensions affecting Chinese issuers or other factors, the potential that the Chinese government may expand restrictions on foreign investments or the repatriation of capital, and the implementation of new tariffs or other trade barriers by China or its trading partners. A lack of transparency respecting Chinese companies may also reduce the Fund’s ability to conduct diligence respecting those companies’ accounting and governance standards, which may in turn reduce the Fund’s ability to detect fraudulent practices that may adversely affect the companies’ stock prices.
European Securities Risk. The Fund is more exposed to the economic and political risks of Europe and of the European countries in which it invests than funds whose investments are more geographically diversified. Adverse economic and political events, including war, in Europe may cause the Fund’s investments to decline in value. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member states of the European Union (the “EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have historically experienced volatility and adverse trends and these events have and may in the future adversely affect the exchange rate of the euro and may significantly affect other European countries.
Japanese Securities Risk. Because a portion of the assets of the Fund may be invested in Japanese securities, the Fund’s performance may be tied to the political, social and economic conditions within Japan. The Japanese economy has at times in the past been negatively affected by government intervention and protectionism, a deflationary macroeconomic environment, a heavy reliance on international trade and natural disasters. These factors, as well as an aging population, increases in government debt and changes to fiscal, monetary, or trade policies, may affect Japanese markets and the Fund’s performance. As such, the Fund’s performance may be more volatile than the performance of funds that are more geographically diverse.
South Korean Securities Risk. Investments in South Korean issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to South Korea. In addition, economic and political developments of South Korea’s neighbors, including escalated tensions involving North Korea and any outbreak of hostilities involving North Korea, or even the threat of an outbreak of hostilities, may have a severe adverse effect on the South Korean economy.

| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Industry Concentration Risk. Because the Fund’s assets will be concentrated in an industry or group of industries, the Fund is subject to loss due to adverse occurrences that may affect that industry or group of industries.
Semiconductor Industry Risk. Semiconductor companies face intense competition, both domestically and internationally, and such competition may have an adverse effect on profit margins. Semiconductor companies may have limited product lines, markets, financial resources or personnel. The products of semiconductor companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Capital equipment expenditures could be substantial, and equipment generally suffers from rapid obsolescence. Companies in the semiconductor industry are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights would adversely affect the profitability of these companies.

| Risk [Text Block] | Large-Capitalization Risk. Returns on investments in securities of large companies could trail the returns on investments in securities of smaller and mid-sized companies. The securities of large-capitalization companies may also be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

| Tema Semiconductor Manufacturing ETF | Market Risk And Selection Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Market Risk and Selection Risk. The prices of securities held by the Fund may decline in response to certain events taking place around the world, including those directly involving the companies whose securities are owned by the Fund; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency, interest rate and commodity price fluctuations. The equity securities purchased by the Fund may involve large price swings and potential for loss. Investors in the Fund should have a long-term perspective and be able to tolerate potentially sharp declines in value. The market’s daily movements, sometimes called volatility, may be greater or less depending on the types of securities the Fund owns and the markets in which the securities trade. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, climate change or climate related risks, natural disasters, pandemics, epidemics, war, terrorism, regulatory events, governmental or quasi-governmental actions, and public health emergencies. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets.

| Risk [Text Block] | National Closed Market Trading Risk. To the extent that securities or other assets held by the Fund trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between such asset’s current price and its last quoted price (i.e., the quote from the closed foreign market to the Fund). The impact of a closed foreign market on the Fund is likely to be greater where a large portion of the Fund’s holdings trade on a closed foreign market or when a foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other funds.

| Risk [Text Block] | New Fund Risk. A new or smaller fund is subject to the risk that its performance may not represent how the fund is expected to or may perform in the long term. In addition, new funds have limited operating histories for investors to evaluate and new and smaller funds may not attract sufficient assets to achieve investment and trading efficiencies. There can be no assurance that the Fund will achieve an economically viable size. Further, an active trading market for shares of the Fund may not develop or be maintained.

| Tema Semiconductor Manufacturing ETF | Privately Placed Securities Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Privately Placed Securities Risk. The Fund may invest in non-exchange traded securities, including privately placed securities, which are subject to liquidity and valuation risks. These risks may make it difficult for those securities to be traded or valued, especially in the event of adverse economic and liquidity conditions or adverse changes in the issuer’s financial condition. The market for certain non-exchange traded securities may be limited to institutional investors, subjecting such investments to further liquidity risk if a market were to limit institutional trading. There may also be less information available regarding such non-exchange traded securities than for publicly traded securities, which may make it more difficult for the Adviser to fully evaluate the risks of investing in such securities and as a result place the Fund’s assets at greater risk of loss than if the Adviser had more complete information. In addition, the issuers of non-exchange traded securities may be distressed, insolvent, or delinquent in filing information needed to be listed on an exchange. Disposing of nonexchange traded securities, including privately placed securities, may involve time-consuming negotiation and legal expenses, and selling them promptly at an acceptable price may be difficult or impossible. Securities purchased in private placements may be subject to legal or contractual restrictions on resale. The Fund may have to bear the expense of registering restricted securities for resale and the risk of substantial delay in effecting registration.
The Fund may have exposure to restricted securities. Restricted securities are securities with restrictions on public resale, such as securities offered in accordance with an exemption under Rule 144A under the Securities Act of 1933 (the “1933 Act”), or commercial paper issued under Section 4(a)(2) of the 1933 Act. Restricted securities are often required to be sold in private sales to institutional buyers, markets for restricted securities may or may not be well developed, and restricted securities can be illiquid. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions or other economic and market impediments. Funds with principal investment strategies that involve investments in securities of companies with smaller market capitalizations, foreign securities, derivatives, or securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk. Exposure to liquidity risk may be heightened for funds that invest in securities of emerging markets and related derivatives that are not widely traded, and that may be subject to purchase and sale restrictions.

| Tema Semiconductor Manufacturing ETF | Proprietary Infrastructure Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Proprietary Infrastructure Risk. The success of the Fund’s investment strategy depends in part on the ability of the companies in which it invests to maintain proprietary technology used in their products and services. Companies in which the Fund invests will rely, in part, on patent, trade secret and trademark law to protect that technology, but competitors may misappropriate their intellectual property, and disputes as to ownership of intellectual property may arise. Consequently, companies in which the Fund invests may, from time to time, be required to institute litigation in order to enforce their patents, copyrights or other intellectual property rights, to protect their trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement. Such litigation could result in substantial costs and diversion of resources. Similarly, if a company is found to infringe upon or misappropriate a third-party’s patent or other proprietary rights, that company could be required to pay damages to such third-party, alter its own products or processes, obtain a license from the third-party and/or cease activities utilizing such proprietary rights, including making or selling products utilizing such proprietary rights.

The Fund may invest a significant portion of its assets in one or more sectors and thus will be more susceptible to the risks affecting those sectors than funds that have more diversified holdings across a number of sectors. The Fund anticipates that it may be subject to some or all of the risks described below.
Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on their profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of any of these rights may adversely affect the profitability of these companies or the Fund’s performance.

| Tema Semiconductor Manufacturing ETF | Semiconductor Company Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Semiconductor Company Risk. Competitive pressures may have a significant effect on the financial condition of companies in the semiconductor industry. As product cycles shorten and manufacturing capacity increases, these companies may become increasingly subject to aggressive pricing, which hampers profitability. Semiconductor companies are vulnerable to wide fluctuations in securities prices due to rapid product obsolescence. Many semiconductor companies may not successfully introduce new products, develop and maintain a loyal customer base or achieve general market acceptance for their products, and failure to do so could have a material adverse effect on their business, results of operations and financial condition. Reduced demand for end-user products, underutilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductor industry. Semiconductor companies typically face high capital costs and these companies may need additional financing, which may be difficult to obtain. They also may be subject to risks relating to research and development costs and the availability and price of components. Moreover, they may be heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. Some of the companies involved in the semiconductor sector are also engaged in other lines of business unrelated to the semiconductor business, and they may experience problems with these lines of business, which could adversely affect their operating results. The international operations of many semiconductor companies expose them to risks associated with instability and changes in economic and political conditions, foreign currency fluctuations, changes in foreign regulations, tariffs and trade disputes, competition from subsidized foreign competitors with lower production costs and other risks inherent to international business. The semiconductor industry is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. Companies in the semiconductor industry also may be subject to competition from new market entrants. The stock prices of companies in the semiconductor industry have been and will likely continue to be extremely volatile compared to the overall market.

| Risk [Text Block] | Artificial Intelligence Technology Risk. Companies in the artificial intelligence (“AI”) and technology industries typically have high research and capital expenditures and, as a result, their profitability can vary widely, if they are profitable at all. The space in which they are engaged is highly competitive and issuers’ products and services may become obsolete very quickly. These companies are heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. The issuers are also subject to legal, regulatory and political changes that may have a large impact on their profitability. A failure in an issuer’s product or even questions about the safety of the product could be devastating to the issuer, especially if it is the marquee product of the issuer. It can be difficult to accurately capture what qualifies as an AI and Technology company.

| Risk [Text Block] | Common Stock Risk. Common stock holds the lowest priority in the capital structure of a company, and, therefore, takes the largest share of the company’s risk and its accompanying volatility.

| Risk [Text Block] | Currency Risk. The Fund may invest its assets in securities denominated in non-U.S. currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of the shares. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of the non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the value of the Fund’s holdings, measured in the foreign currency, increases. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

Information and technology systems relied upon by the Fund, the Adviser, the Fund’s other service providers (including, but not limited to, the Fund Accountant, Custodian, Transfer Agent, Administrator and Distributor), market makers, Authorized Participants, financial intermediaries and/or the issuers of securities in which the Fund invests may be vulnerable to damage or interruption from computer viruses, network failures, computer and telecommunication failures, infiltration by unauthorized persons, security breaches, usage errors, power outages and catastrophic events such as fires, tornadoes, floods, hurricanes and earthquakes. Although the Adviser and the Fund’s other service providers have implemented measures to manage risks relating to these types of events, if these systems are compromised, become inoperable for extended periods of time or cease to function properly, significant investment may be required to fix or replace them. The failure of these systems and/or of disaster recovery plans could cause significant interruptions in the operations of the Fund, the Adviser, the Fund’s other service providers, market makers, Authorized Participants, financial intermediaries and/or issuers of securities in which the Fund invests and may result in a failure to maintain the security, confidentiality or privacy of sensitive data, impact the Fund’s ability to calculate its NAV or impede trading.

| Risk [Text Block] | Depositary Receipt Risk. The Fund may invest in depositary receipts which involve similar risks to those associated with investments in foreign securities. Investments in depositary receipts may be less liquid than the underlying shares in their primary trading market.
ADRs and GDRs may be subject to some of the same risks as direct investment in foreign companies, which includes international trade, currency, political, regulatory and diplomatic risks. In a sponsored ADR or GDR arrangement, the foreign issuer assumes the obligation to pay some or all of the depositary’s transaction fees. Under an unsponsored ADR or GDR arrangement, the foreign issuer assumes no obligations and the depositary’s transaction fees are paid directly by the ADR or GDR holders. Because unsponsored ADR and GDR arrangements are organized independently and without the cooperation of the issuer of the underlying securities, available information concerning the foreign issuer may not be as current as for sponsored ADRs and GDRs and voting rights with respect to the deposited securities that are not passed through.

| Tema Semiconductor Substrates ETF | Fluctuation Of Net Asset Value Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Fluctuation of Net Asset Value Risk. The NAV of the Fund’s shares will generally fluctuate with changes in the market value of the Fund’s holdings. The market prices of the shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of and demand for shares on [ ] (the “Exchange”). The Adviser cannot predict whether the shares will trade below, at or above their NAV. The Fund’s market price may deviate from the value of its underlying portfolio holdings, particularly in times of market stress, with the result that investors may pay significantly more or receive significantly less than the underlying value of the Fund shares bought or sold. This can be reflected as a spread between the bid and ask prices for the Fund quoted during the day or a premium or discount in the closing price from the Fund’s NAV. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material effect on the market price of the Fund’s shares.

Investments in securities (including ADRs and GDRs) of foreign issuers involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers. The values of foreign investments may be affected by changes in exchange control regulations, application of foreign tax laws (including withholding tax) changes in governmental administration or economic or monetary policy (in this country or abroad) or changed circumstances in dealings between nations.

| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Geographic Investment Risk. To the extent the Fund is significantly comprised of securities of issuers from a single country, the Fund would be more likely to be impacted by events or conditions affecting that country.
Chinese Securities Risk. A portion of the Fund’s assets may be invested in companies exposed to China. Risks affecting investments in China include a potential downturn in the Chinese economy, reduced liquidity or increased price volatility in the Chinese securities markets as a result of trading suspensions affecting Chinese issuers or other factors, the potential that the Chinese government may expand restrictions on foreign investments or the repatriation of capital, and the implementation of new tariffs or other trade barriers by China or its trading partners. A lack of transparency respecting Chinese companies may also reduce the Fund’s ability to conduct diligence respecting those companies’ accounting and governance standards, which may in turn reduce the Fund’s ability to detect fraudulent practices that may adversely affect the companies’ stock prices.
European Securities Risk. The Fund is more exposed to the economic and political risks of Europe and of the European countries in which it invests than funds whose investments are more geographically diversified. Adverse economic and political events, including war, in Europe may cause the Fund’s investments to decline in value. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member states of the European Union (the “EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have historically experienced volatility and adverse trends and these events have and may in the future adversely affect the exchange rate of the euro and may significantly affect other European countries.
Japanese Securities Risk. Because a portion of the assets of the Fund may be invested in Japanese securities, the Fund’s performance may be tied to the political, social and economic conditions within Japan. The Japanese economy has at times in the past been negatively affected by government intervention and protectionism, a deflationary macroeconomic environment, a heavy reliance on international trade and natural disasters. These factors, as well as an aging population, increases in government debt and changes to fiscal, monetary, or trade policies, may affect Japanese markets and the Fund’s performance. As such, the Fund’s performance may be more volatile than the performance of funds that are more geographically diverse.
South Korean Securities Risk. Investments in South Korean issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to South Korea. In addition, economic and political developments of South Korea’s neighbors, including escalated tensions involving North Korea and any outbreak of hostilities involving North Korea, or even the threat of an outbreak of hostilities, may have a severe adverse effect on the South Korean economy.

The prices of securities held by the Fund may decline in response to certain events taking place around the world, including those directly involving the companies whose securities are owned by the Fund; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency, interest rate and commodity price fluctuations. The equity securities purchased by the Fund may involve large price swings and potential for loss. Investors in the Fund should have a long-term perspective and be able to tolerate potentially sharp declines in value. The market’s daily movements, sometimes called volatility, may be greater or less depending on the types of securities the Fund owns and the markets in which the securities trade. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, climate change or climate related risks, natural disasters, pandemics, epidemics, war, terrorism, regulatory events, governmental or quasi-governmental actions, and public health emergencies. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets.

| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Micro-Capitalization Risk. The micro-capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies, and may underperform other segments of the market or the equity market as a whole. Securities of micro-capitalization companies generally trade in lower volumes, are often more vulnerable to market volatility, and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole.

| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | National Closed Market Trading Risk. To the extent that securities or other assets held by the Fund trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between such asset’s current price and its last quoted price (i.e., the quote from the closed foreign market to the Fund). The impact of a closed foreign market on the Fund is likely to be greater where a large portion of the Fund’s holdings trade on a closed foreign market or when a foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other funds.

| Tema Semiconductor Substrates ETF | New Fund Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | New Fund Risk. A new or smaller fund is subject to the risk that its performance may not represent how the fund is expected to or may perform in the long term. In addition, new funds have limited operating histories for investors to evaluate and new and smaller funds may not attract sufficient assets to achieve investment and trading efficiencies. There can be no assurance that the Fund will achieve an economically viable size. Further, an active trading market for shares of the Fund may not develop or be maintained.

| Tema Semiconductor Substrates ETF | Nondiversified Fund Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Non-Diversified Fund Risk. The Fund is a non-diversified investment company under the Investment Company Act of 1940 (the “1940 Act”), meaning that, as compared to a diversified fund, it can invest a greater percentage of its assets in securities issued by or representing a small number of issuers. As a result, the performance of these issuers can have a substantial impact on the Fund’s performance.

| Tema Semiconductor Substrates ETF | Operational Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third parties, failed or inadequate processes and technology or systems failures. The Fund seeks to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

| Tema Semiconductor Substrates ETF | Privately Placed Securities Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Privately Placed Securities Risk. The Fund may invest in non-exchange traded securities, including privately placed securities, which are subject to liquidity and valuation risks. These risks may make it difficult for those securities to be traded or valued, especially in the event of adverse economic and liquidity conditions or adverse changes in the issuer’s financial condition. The market for certain non-exchange traded securities may be limited to institutional investors, subjecting such investments to further liquidity risk if a market were to limit institutional trading. There may
also be less information available regarding such non-exchange traded securities than for publicly traded securities, which may make it more difficult for the Adviser to fully evaluate the risks of investing in such securities and as a result place the Fund’s assets at greater risk of loss than if the Adviser had more complete information. In addition, the issuers of non-exchange traded securities may be distressed, insolvent, or delinquent in filing information needed to be listed on an exchange. Disposing of nonexchange traded securities, including privately placed securities, may involve time-consuming negotiation and legal expenses, and selling them promptly at an acceptable price may be difficult or impossible. Securities purchased in private placements may be subject to legal or contractual restrictions on resale. The Fund may have to bear the expense of registering restricted securities for resale and the risk of substantial delay in effecting registration.
The Fund may have exposure to restricted securities. Restricted securities are securities with restrictions on public resale, such as securities offered in accordance with an exemption under Rule 144A under the Securities Act of 1933 (the “1933 Act”), or commercial paper issued under Section 4(a)(2) of the 1933 Act. Restricted securities are often required to be sold in private sales to institutional buyers, markets for restricted securities may or may not be well developed, and restricted securities can be illiquid. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions or other economic and market impediments. Funds with principal investment strategies that involve investments in securities of companies with smaller market capitalizations, foreign securities, derivatives, or securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk. Exposure to liquidity risk may be heightened for funds that invest in securities of emerging markets and related derivatives that are not widely traded, and that may be subject to purchase and sale restrictions.

| Tema Semiconductor Substrates ETF | Proprietary Infrastructure Risk [Member] | ||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Proprietary Infrastructure Risk. The success of the Fund’s investment strategy depends in part on the ability of the companies in which it invests to maintain proprietary technology used in their products and services. Companies in which the Fund invests will rely, in part, on patent, trade secret and trademark law to protect that technology, but competitors may misappropriate their intellectual property, and disputes as to ownership of intellectual property may arise. Consequently, companies in which the Fund invests may, from time to time, be required to institute litigation in order to enforce their patents, copyrights or other intellectual property rights, to protect their trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement. Such litigation could result in substantial costs and diversion of resources. Similarly, if a company is found to infringe upon or misappropriate a third-party’s patent or other proprietary rights, that company could be required to pay damages to such third-party, alter its own products or processes, obtain a license from the third-party and/or cease activities utilizing such proprietary rights, including making or selling products utilizing such proprietary rights.

| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Sector Focus Risk. The Fund may invest a significant portion of its assets in one or more sectors and thus will be more susceptible to the risks affecting those sectors than funds that have more diversified holdings across a number of sectors. The Fund anticipates that it may be subject to some or all of the risks described below.
Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on their profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of any of these rights may adversely affect the profitability of these companies or the Fund’s performance.

| Prospectus [Line Items] | ||||||||||||||||||||||
| Risk [Text Block] | Semiconductor Company Risk. Competitive pressures may have a significant effect on the financial condition of companies in the semiconductor industry. As product cycles shorten and manufacturing capacity increases, these companies may become increasingly subject to aggressive pricing, which hampers profitability. Semiconductor companies are vulnerable to wide fluctuations in securities prices due to rapid product obsolescence. Many semiconductor companies may not successfully introduce new products, develop and maintain a loyal customer base or achieve general market acceptance for their products, and failure to do so could have a material adverse effect on their business, results of operations and financial condition. Reduced demand for end-user products, underutilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductor industry. Semiconductor companies typically face high capital costs and these companies may need additional financing, which may be difficult to obtain. They also may be subject to risks relating to research and development costs and the availability and price of components. Moreover, they may be heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. Some of the companies involved in the semiconductor sector are also engaged in other lines of business unrelated to the semiconductor business, and they may experience problems with these lines of business, which could adversely affect their operating results. The international operations of many semiconductor companies expose them to risks associated with instability and changes in economic and political conditions, foreign currency fluctuations, changes in foreign regulations, tariffs and trade disputes, competition from subsidized foreign competitors with lower production costs and other risks inherent to international business. The semiconductor industry is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. Companies in the semiconductor industry also may be subject to competition from new market entrants. The stock prices of companies in the semiconductor industry have been and will likely continue to be extremely volatile compared to the overall market.

| Risk [Text Block] | Securities Lending Risk. Although the Fund will receive collateral in connection with all loans of its securities holdings, the Fund would be exposed to a risk of loss should a borrower default on its obligation to return the borrowed securities (e.g., the loaned securities may have appreciated beyond the value of the collateral held by the Fund). In addition, the Fund will bear the risk of loss of any cash collateral that it invests.

| Risk [Text Block] | Value-Oriented Investment Strategies Risk. The Fund seeks to invest in stocks that are believed to be undervalued in comparison to their fundamentals and growth opportunities. Value investing is subject to the risk that the market will not recognize a security’s inherent value for a long time or at all, or that a stock judged to be undervalued may actually be appropriately priced or overvalued. In addition, during some periods (which may be extensive), value stocks generally may be out of favor in the markets. |

Additionally, purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund’s NAV to the extent not offset by a transaction fee payable by an AP.
