TSMC Removes Chinese Equipment From 2nm Fabs as U.S. Policy Reshapes Its Supply Chain

A new generation of chips brings a change in suppliers

Taiwan Semiconductor Manufacturing Company (TSMC), the world's largest contract chipmaker, is removing all Chinese equipment from its new production lines for 2-nanometer chips as it prepares to launch its most advanced manufacturing process. As of August 31, 2025, the shift connects a major technological upgrade with decisions about American subsidies, supplier costs and the growing rivalry between the United States and China.

TSMC's 2nm process promises a performance increase of 10% to 15% and a reduction in power consumption of 25% to 30% compared with its current 3nm chips, according to the company. Apple, Nvidia, AMD and Qualcomm are already lining up for production, with Apple reportedly securing nearly half of the initial capacity.

The equipment change reaches beyond the machines inside a semiconductor factory, known as a fab. TSMC is also auditing materials, chemicals and gases used in Taiwan and the United States, while examining the costs and business exposure of Taiwanese suppliers that could appear on its approved vendor list for 2026.

A central concern is the proposed U.S. Chip EQUIP Act. The bipartisan bill would restrict semiconductor equipment supplied by foreign entities of concern, a category that includes Chinese companies, for businesses receiving American subsidies or tax credits. TSMC stands to receive billions in U.S. government incentives for its Arizona factories.

The bill is still moving through Congress. TSMC's decision is therefore a response to anticipated restrictions as well as the technical demands of its next generation of chips. For equipment makers, the change means that access to advanced production lines increasingly depends on ownership and political exposure alongside price and manufacturing capability.

What makes the 2nm process different?

TSMC's 2nm technology represents the next step in making chips faster and more efficient. In chipmaking, the nanometer designation refers to the size of the smallest features that can be etched onto a silicon wafer. Smaller features allow more transistors to fit on a chip, supporting faster performance, lower power consumption and greater efficiency.

A transistor is a tiny switch that controls electrical signals. A chip contains many of these switches working together to carry out calculations. The way a transistor is built matters because it affects how effectively the chip controls electricity and how much energy it uses.

TSMC's 2nm process will be its first to use gate-all-around (GAA) transistors. This is a major architectural change from the FinFET design that has dominated the industry for more than a decade. In simple terms, the gate controls the flow of electricity through a transistor, and the new design surrounds the channel through which that electricity travels.

The company's projected gains matter for smartphones, artificial intelligence (AI) accelerators and high-performance computing devices. A faster chip can handle more work, while a chip that consumes less power can perform its tasks with a smaller energy requirement. Both are valuable for devices and computing systems that face growing demands.

The transition also places greater demands on the manufacturing equipment. Producing these chips requires precise, reliable tools throughout the factory. TSMC's supplier choices therefore sit at the meeting point of transistor design, production quality and government policy.

Why Chinese equipment is being removed

TSMC has used Chinese tools in earlier advanced manufacturing processes, including etching machines from Advanced Micro-Fabrication Equipment Inc. China (AMEC) and systems from Mattson Technology. Mattson was acquired by a Chinese investor in 2016. Etching equipment removes selected material from a wafer as chip structures are formed.

The proposed Chip EQUIP Act creates a financial reason to change those relationships. TSMC is proactively phasing out the suppliers to protect access to American markets and government incentives as U.S. lawmakers seek tighter restrictions.

An industry analyst described the removal of Chinese tools as a strategic decision that extends beyond the engineering requirements of the new process:

TSMC's removal of Chinese tools from 2nm production marks more than a technical shift—it's a strategic realignment in a world where chipmaking is as political as it is technological.

TSMC also needs equipment capable of meeting the demands of 2nm production and GAA transistors. ASML of the Netherlands, Applied Materials of the United States and Tokyo Electron of Japan are among the global leaders supplying advanced tools. In critical areas such as lithography, metrology and process control, these established suppliers are far ahead of Chinese competitors.

Lithography creates the patterns used to build chip structures. Metrology measures those structures, while process control helps keep production consistent. Small errors can matter when the features being manufactured are extremely small, making precision central to the equipment decision.

Standardizing on leading tools serves two purposes for TSMC: supporting its technological position and reducing regulatory risk. The company is making that adjustment while the proposed American legislation is still under consideration.

How U.S. incentives shape the decision

The Chip EQUIP Act would amend the CHIPS and Science Act to prevent federally funded projects from buying semiconductor manufacturing equipment from Chinese companies or other foreign entities of concern. Its proposed restrictions also address companies receiving American tax credits or subsidies.

The U.S. government's wider effort to restrict Chinese technology in advanced chipmaking is tied to maintaining an advantage in the global technology race, particularly in AI and defense. Semiconductor supply chains have consequently become part of national security policy as well as industrial planning.

TSMC's Arizona expansion makes this policy especially consequential for the company. Billions in anticipated government incentives give it a strong reason to ensure that its U.S. facilities meet equipment requirements. The company's plans also suggest that American production could eventually account for a substantial share of its most advanced chips.

TSMC chief executive C.C. Wei described the potential scale of that expansion:

TSMC is accelerating its U.S. expansion, with up to 30 percent of our most advanced production—2nm and below—potentially coming from U.S. plants in the future.

That possible share links the supplier decision to a large part of TSMC's future advanced manufacturing. Other global chipmakers are also reviewing their supply chains to reduce reliance on Chinese equipment and materials as governments place greater weight on security and control over critical technologies.

The review extends to chemicals and materials

TSMC is conducting comprehensive audits of the materials, chemicals and gases used in its Taiwan and U.S. fabs, aiming to minimize exposure to Chinese suppliers. The equipment change is therefore one part of a broader effort to manage where essential factory inputs come from.

High-purity chemicals, specialty gases and wafers without defects are critical to advanced chip production. These inputs support the manufacturing steps that turn a silicon wafer into working chips. A disruption in their supply could have consequences worth billions of dollars.

TSMC is also scrutinizing Taiwanese equipment and materials vendors. Suppliers with high profit margins or heavy reliance on sales to China may be excluded from its approved vendor list for 2026. The review brings supplier pricing and commercial exposure into the same assessment as technical capability.

The company is pursuing two connected goals: aligning its supply chain with U.S. policy and exercising tighter control over costs and supplier risks. A factory needs dependable inputs, but the companies providing them must also fit the financial and regulatory conditions under which TSMC operates.

Taiwanese firms face their own difficult choices. Vendors excluded from TSMC's supply chain may turn further toward China for business. That could deepen the division TSMC is trying to manage, even as the chipmaker seeks to reduce its own exposure to Chinese suppliers.

China has strengths, but advanced equipment gaps persist

China has made substantial progress in developing semiconductor equipment for etching, thin-film deposition and cleaning. Thin-film deposition adds layers of material to a wafer, while cleaning removes unwanted material during manufacturing. Companies such as Naura have become major global players.

The strongest remaining gaps are in the most advanced areas, including lithography, sophisticated metrology and ion implantation. Ion implantation is a manufacturing process used to change the electrical properties of selected parts of a chip. Localization rates in these advanced equipment segments remain below 10%.

Those gaps help explain why TSMC and other leading chipmakers continue to rely on suppliers outside China for their most advanced production lines. Progress in one type of equipment cannot supply every tool needed to manufacture a leading chip.

China is investing heavily in domestic innovation and efforts to localize its semiconductor supply chain. Its objective is greater self-sufficiency in manufacturing. TSMC's decision adds commercial pressure to that effort by removing access to a major customer at the leading edge of chip production.

AMEC and Mattson Technology face the loss of business from TSMC's new 2nm lines. Their situation illustrates how a supplier's market access can be shaped by geopolitical considerations alongside the quality and price of its equipment.

What the shift means for customers and vendors

Apple is expected to take nearly half of TSMC's initial 2nm capacity, and the new chips are likely to appear in the iPhone 18 series in 2026. That expected allocation makes Apple a central customer in the first stage of the manufacturing transition.

Nvidia, AMD and Qualcomm are also among the major customers seeking the new process. AMD, Broadcom, Intel, MediaTek and Qualcomm are among the companies expected to benefit from its gains in performance and efficiency. Their interest reflects the importance of advanced chips across smartphones, AI and demanding computing applications.

TSMC's customers have a practical interest in dependable production. A manufacturing interruption can affect the supply of the chips needed for their devices and systems. TSMC's equipment choices and broader audits aim to support uninterrupted access to advanced manufacturing while maintaining eligibility for American support.

Equipment and materials vendors face a wider set of requirements. Technical quality and competitive costs remain essential, but suppliers must also demonstrate that their ownership, business exposure and risk management fit the conditions surrounding TSMC's factories.

An industry observer described how those pressures are changing the competition around the new process:

The race to 2nm is being shaped as much by politics and economics as by transistor physics. The supply chain is narrowing to a smaller pool of politically acceptable players.

TSMC gains a route toward regulatory compliance, continued government support and technological leadership. Chinese suppliers lose access to advanced manufacturing business, while Taiwanese vendors must balance the value of serving TSMC against their costs and exposure to China.

The dates behind the transition

TSMC's supplier shift connects an earlier change in equipment ownership with decisions affecting the next generation of factories and products. The key dates and stated expectations are:

• 2016: Mattson Technology was acquired by a Chinese investor.
• August 31, 2025: TSMC is preparing to launch its 2nm production lines and removing Chinese equipment as the proposed Chip EQUIP Act moves through Congress.
• 2026: TSMC's supplier review may exclude some Taiwanese vendors from its approved list.
• 2026: Chips made with the new process are expected to appear in Apple's iPhone 18 series.

The supplier decisions reach into a global industry whose products power smartphones, data centers, cars and medical devices. Disruptions in semiconductor production can consequently spread across industries and countries, far beyond the companies manufacturing chips.

TSMC must balance compliance and control with the realities of a global supply chain. Its move reflects a broader division between the United States and its allies on one side and China on the other, driven by concerns about security, technological leadership and economic competitiveness.

For China, the decision adds urgency to closing advanced equipment gaps. For TSMC, it ties the success of its new transistor architecture to the reliability, cost and political acceptability of the companies supplying its factories.
