TSMC’s 2 nm Fabs Lock Out China OEMs, Securing ALD and Process Tool Demand for US, European, and Japanese Tier-1 Suppliers

TSMC’s decision to exclude Chinese equipment vendors from its 2 nm fabs in Taiwan and the US reshapes the competitive landscape in favor of Japanese, American, and European suppliers. With the 2 nm node set to become the largest in history by wafer volume and revenue potential, this policy shift effectively concentrates demand among a handful of Tier 1 players —ASMI, TEL, Applied Materials, and Lam Research—who already dominate in deposition, etch, and cleaning tools essential for nanosheet GAA and backside power delivery. No need to mention ASML.


Announced in January: TSMC is advancing with its 2 nm (N2) technology, establishing a pilot line at its Hsinchu Baoshan Fab 20 with an initial monthly output of around 3,000–3,500 wafers. By combining production from Hsinchu and Kaohsiung, the company expects to exceed 50,000 wafers per month by the end of 2025 and reach about 125,000 wafers per month by the end of 2026. Output at Hsinchu should rise to 20,000–25,000 wafers per month by late 2025 and 60,000–65,000 by early 2027, while Kaohsiung is projected to produce 25,000–30,000 wafers monthly by late 2025 and also expand to 60,000–65,000 by early 2027. Chairman C.C. Wei has highlighted that demand for 2 nm exceeds that of 3 nm, driven by its 24–35% lower power consumption, 15% performance boost at the same power, and 15% higher transistor density. Apple will be the first adopter, followed by MediaTek, Qualcomm, Intel, NVIDIA, AMD and Broadcom.

TSMC will start 2 nm mass production in Taiwan in the second half of 2025, initially with Fab 22 in Kaohsiung as the anchor site for yield learning. The first ramp is set at 40,000 wafers per month, expanding to 100,000 wafers per month in 2026 and reaching 200,000 wafers per month by 2027, making N2 the largest and most profitable node in TSMC’s history.

In the US, Arizona Fab 21 is being developed in phases. Phase 1 is already producing 4 nm chips, Phase 2 will start 3 nm by late 2025 or early 2026, and Phase 3 is planned for 2 nm and A16-class chips toward the end of the decade. This ensures that while Taiwan remains the cost-optimized base for N2 production, Arizona provides premium, subsidy-supported capacity for US customers, diversifying geographic and geopolitical risk.

Overall, Taiwan will carry the bulk of N2 output and cost efficiency, while Arizona secures local supply for strategic US clients like Apple, Nvidia, AMD, and Intel. By 2027, with 200,000 wafers per month globally, N2 alone could generate nearly $50 billion annually, cementing TSMC’s central role in powering AI and HPC expansion.

The move aligns directly with Washington’s Chip EQUIP Act, which ties subsidies to avoiding “foreign entities of concern.” By pre-emptively removing Chinese tools, TSMC safeguards its access to US incentives while giving its global customers—Apple, Nvidia, AMD, and Intel—assurance that supply chains are insulated from geopolitical risk. This codifies the leading suppliers as the “trusted” baseline for advanced-node capacity worldwide, effectively reinforcing their moat at the most profitable process node ever.

For ASMI, TEL, AMAT, and Lam, the outlook is very positive. With Chinese competitors pushed out, these companies can win more business and have stronger pricing power. At the same time, 2 nm wafer prices are climbing toward $30,000, far above older smartphone-focused nodes. TSMC is reviewing its suppliers for profit margins and China ties, but these four are essential for 2 nm production, so they are more likely to gain from rising demand and higher-value tools than lose ground. Put simply, the 2 nm era is set to drive lasting growth and profits for them as AI adoption accelerates through 2027.

Chinese semiconductor equipment OEMs that are cut out from TSMC’s 2 nm fabs under the new restrictions and supplier realignment:

  • AMEC (Advanced Micro-Fabrication Equipment Inc.) – leading Chinese etch tool supplier, with relevance in dielectric etch and epitaxy
  • Naura Technology Group – broad portfolio in etch, deposition, and cleaning tools
  • Mattson Technology (China-owned, via E-Town Dragon Semiconductor) – focuses on dry strip, rapid thermal processing (RTP), and etch
  • SMEE (Shanghai Micro Electronics Equipment) – China’s only domestic lithography tool maker (far behind in capability, but relevant in domestic fabs)
  • Kingsemi – maker of ALD/CVD equipment, mainly for memory and advanced logic
  • Piotech – deposition (CVD, PECVD, ALD) equipment vendor
  • ACM Research (China) – cleaning and electrochemical deposition tools (though headquartered in the US, its operations are China-based and increasingly seen as China OEM)

At TSMC’s 2 nm fabs, the exclusion of Chinese equipment vendors channels ALD equipment demand entirely to US, European, and Japanese suppliers. ASM International (Europe) remains the clear leader in single-wafer ALD for high-k metal gate stacks and nanosheet spacers, with Applied Materials and Lam Research (US) competing in selective and plasma ALD for gate-all-around and backside power steps, while Tokyo Electron and Kokusai Electric (Japan) cover both single-wafer and batch ALD, particularly for spacer and liner deposition. By contrast, Chinese ALD players such as Naura, Kingsemi, and Piotech, while active in domestic logic and memory at 28–14 nm and some 7 nm non-EUV capacity, will not gain any capability at N2 and are explicitly excluded under TSMC’s supplier policy and US subsidy rules, leaving the largest and most profitable ALD opportunity in history to be divided among the established US, European, and Japanese Tier-1 suppliers.

Lam anticipates a recovery in NAND spending in 2025, largely driven by technology upgrades rather than new capacity expansions. Key factors include a transition from tungsten to molybdenum in NAND structures, which improves performance by reducing resistivity. Lam is well-positioned in this area due to its extensive installed base and production wins, projecting an advantageous position as these upgrades scale into 2025.

NAND Technology Upgrades Set to Drive Etch and Deposition Demand in 2025

While the NAND segment has been in a prolonged downturn, Lam anticipates a recovery in 2025 as manufacturers upgrade to advanced nodes. The push toward 3D NAND layers exceeding 200 is essential to meet the growing demand for high-speed, high-capacity storage in data centers and client devices. Currently, about two-thirds of NAND capacity remains at older technology nodes, highlighting significant room for technology upgrades. Lam’s extensive installed base of NAND equipment positions it well to benefit as customers look to improve efficiency and performance.

Furthermore, Archer highlighted a shift from tungsten to molybdenum as a key materials change in NAND, addressing word line resistance challenges. This transition is particularly favorable for Lam, as it has already secured production wins in molybdenum deposition, which will scale up throughout 2025. These advancements are expected to enhance Lam's leadership position in NAND technology transitions.

Lam's product offerings mentioned in the reporting, along with their primary applications and strategic impacts.

Advanced Logic and Foundry Nodes: Key Growth Segments for Lam

Lam is also poised to benefit from shifts in advanced logic and foundry nodes, which are increasingly adopting gate-all-around architectures, backside power distribution, and advanced EUV patterning. These cutting-edge technologies require more intensive use of etch and deposition processes, aligning with Lam’s expertise and product offerings.

Archer noted the company's recent wins in selective etch tools and other innovations that support these advanced nodes, positioning Lam favorably as customers transition to architectures with greater power and performance needs. This expanding demand from foundry and logic customers offers a substantial growth opportunity for Lam’s advanced etch and deposition technologies.

Advanced Packaging Driven by AI Fuels Revenue Growth

The AI and high-performance computing boom has intensified demand for advanced packaging, particularly for high-bandwidth memory (HBM). Lam’s copper plating technology, SABRE 3D, has experienced substantial adoption, doubling its market share this year. This growth has been fueled by the rising complexity of 2.5D and 3D packages, which require high-performance interconnections to support AI-driven systems.

Lam anticipates this trend will continue into 2025 as the industry moves toward more advanced and intricate packaging solutions. According to Archer, advanced packaging will play a critical role in the semiconductor ecosystem for the foreseeable future, and Lam’s early investment in this technology has positioned it for continued market share gains.

Supporting Installed Base and Productivity in Memory Markets

Lam’s Customer Support Business Group (CSBG) has also shown growth, focusing on productivity enhancements and tool reuse. With Lam’s extensive tool installations in both DRAM and NAND, customers are prioritizing upgrades over entirely new systems, especially as they look to improve cost efficiency during NAND’s down cycle. This focus on tool reuse has led to recent market share gains for Lam, as existing tools are upgraded for better value than new installations.

Lam has already secured production wins for ALD applications with molybdenum, expected to ramp up significantly in 2025. This capability extends beyond NAND, with potential applications in DRAM and advanced logic/foundry nodes, underscoring ALD’s growing importance in meeting next-generation semiconductor demands.

Lam Research Adapts to Regulatory Challenges as China Revenue Set to Decline in 2025

In its Q1 2025 earnings presentation, Lam Research highlighted key developments and expectations for the China market. China accounted for roughly 37% of Lam's revenue in the September quarter, but the company anticipates this share will decrease to around 30% by December and potentially decline further in 2025. This projected downturn reflects both anticipated shifts in demand and the impact of U.S. export restrictions on advanced semiconductor equipment sales to China. Lam acknowledged the challenges posed by ongoing and potential new U.S. export controls, which could limit its ability to sell to certain advanced technology segments in China. Nevertheless, Lam remains committed to supporting its domestic Chinese customers within the boundaries of regulatory compliance, expecting demand in restricted segments to normalize as global WFE (wafer fabrication equipment) spending adjusts.


Much of Lam's business in China now focuses on servicing domestic fabs with tools for trailing-edge and specialty node processes, areas that generally remain unaffected by export controls. Through its Reliant product line, Lam continues to support these nodes, emphasizing upgrades and maintenance services as primary offerings in a market constrained by new advanced technology sales. Despite potential reductions in advanced equipment sales, the company is confident that its service and support model will help stabilize revenue in the region. By prioritizing productivity solutions and customer support, Lam is adapting to a complex regulatory environment while anticipating that China’s share of its revenue will gradually normalize amid a broader decline in WFE spending in the country.

Strategic Positioning in 2025 and Beyond

In summary, Lam Research is set to capitalize on a growing demand for etch and deposition technology driven by the industry’s shift to advanced architectures. Archer concluded the call with optimism, stating that the company is well-positioned to capture market share as the semiconductor industry increasingly relies on complex, three-dimensional structures. With its advanced product offerings, Lam expects to outperform overall wafer fabrication equipment (WFE) growth in 2025, strengthening its leadership across multiple semiconductor sectors.

Applied Materials to present New Innovations Needed to Continue Scaling Advanced Logic (June 16)

Applied Materials (Santa Clara, USA): The semiconductor industry is at a crossroads. Demand for chips has never been greater as we enter the early stages of a new wave of growth fueled by the Internet of Things, Big Data and AI. At the same time, it’s become apparent that conventional Moore’s Law 2D scaling techniques are no longer able to deliver the consistent improvements in power, performance, area-cost and time to market (PPACt) that chipmakers have long relied on. This is particularly the case for logic chips, which serve as the main processing engine in nearly every electronic product and where power efficiency and performance are critical.

To shed light on this issue, Applied Materials is hosting an online Logic Master Class on Wednesday, June 16. I will be joined by other experts from Applied and the industry to discuss the logic scaling roadmap, including challenges and solutions for delivering continued improvements in PPACt. We will be exploring several different areas, including transistor and interconnect scaling, patterning and design technology co-optimization (DTCO). The common denominator underlying all of these areas is the need to supplement classic 2D scaling with a combination of approaches that includes new chip architectures, new 3D structures, novel materials, new ways to shrink features and new ways to connect chips with advanced packaging.
