Semiconductor Equipment: The Chokepoint Technology of the AI Era
No segment of the global technology supply chain has become more directly entangled with great-power competition than semiconductor manufacturing equipment. The machines that etch, deposit, clean, and pattern silicon wafers — lithography systems, deposition tools, etch equipment, and wafer cleaning systems — have become the single most consequential chokepoint in the entire technology stack, because controlling access to this equipment is, in practice, the most effective lever available for controlling which nations can manufacture the most advanced chips. 2026 has brought the most significant simultaneous restructuring of U.S. policy, allied trade relationships, and Chinese domestic capability in this market since export controls on advanced semiconductors first began tightening in earnest. Constancy Researchers assesses that the semiconductor equipment market is no longer simply a commercial industry responding to chip demand cycles — it has become a central instrument of industrial and national security policy for the world’s major powers.
Washington's January 2026 Policy Overhaul: Tariffs Replace Blanket Denial
The most significant U.S. policy shift came in mid-January 2026, when the Department of Commerce’s Bureau of Industry and Security fundamentally altered the export licensing posture for advanced computing semiconductors destined for China and Macau — moving from a presumption of denial to case-by-case licensing review, contingent on exporters meeting specific supply, security, and end-user testing conditions. This shift in licensing posture occurred in direct parallel with a separate and equally consequential trade action: on January 14, 2026, the White House announced an immediate 25% tariff on semiconductors meeting specific advanced performance thresholds, following the completion of a Section 232 national security investigation that determined imported semiconductors, semiconductor manufacturing equipment, and their derivative products threatened to impair U.S. national security. Imported semiconductors used domestically — in U.S. data centres, for domestic research and development, in U.S.-based startups, or for non-data-centre civil industrial applications — are exempted from the new tariffs, meaning the policy is structured to penalise exports rather than domestic consumption, while the proclamation explicitly left open the possibility of broader future tariffs depending on the trajectory of ongoing bilateral trade negotiations.
Taiwan's $250 Billion Commitment: Reshoring at Unprecedented Scale
Alongside the new licensing and tariff framework, the United States and Taiwan reached a landmark trade agreement, also effective January 15, 2026, that offers Taiwanese chipmakers expanding U.S. production a reduced tariff rate on semiconductors and related manufacturing equipment — in some cases excluding them entirely from the new Section 232 tariffs. In exchange, Taiwanese companies have committed to invest $250 billion in U.S. manufacturing capacity, including semiconductor fabrication. U.S. Secretary of Commerce Howard Lutnick has indicated the administration’s explicit goal is to bring 40% of Taiwan’s chip supply chain and production to the United States, with the implicit alternative being tariffs of up to 100% of value on imported Taiwanese semiconductors should that reshoring target not be met. This agreement represents one of the most consequential geographic realignments of advanced semiconductor manufacturing capacity in the industry’s history, and the scale of associated equipment procurement — lithography systems, deposition tools, etch equipment, and wafer cleaning systems required to outfit new U.S. fabrication facilities — represents a multi-year demand tailwind for the global semiconductor equipment industry, even as it complicates near-term capital planning for equipment makers navigating where exactly future fab capacity will be sited.
ASML and the Shrinking China Business
ASML, the Dutch lithography equipment maker whose extreme ultraviolet systems remain the only viable technology for manufacturing the most advanced chips, has experienced a direct and material impact from the deepening export control environment. The company has guided that China will account for approximately 20% of total 2026 sales, down sharply from 33% in 2025, reflecting the cumulative effect of multiple years of tightening restrictions on the deep ultraviolet lithography tools that remain ASML’s primary product sold into the Chinese market — the company has never exported its most advanced EUV systems to China at all. The risk environment intensified further in April 2026, when a bipartisan group of U.S. lawmakers introduced the Multilateral Alignment of Technology Controls on Hardware Act, which would, if passed, extend restrictions to cover even ASML’s deep ultraviolet lithography machines — tools that Chinese chipmakers have so far still been able to purchase and that are used to manufacture less-advanced chips including memory. Industry analysts have estimated that DUV lithography tools represent roughly 10 to 15% of ASML’s overall sales, with China accounting for approximately half of that DUV revenue — implying a potential additional hit of around 5% to total company revenue should the legislation advance, a risk that caused ASML’s share price to decline meaningfully upon the bill’s introduction.
China's Domestic Equipment Push: NAURA's Rise and the '50% Mandate'
China’s policy response to sustained export restrictions has been a determined and increasingly effective push toward domestic semiconductor equipment self-sufficiency. NAURA Technology Group entered the top tier of global semiconductor equipment vendors, ranking eighth globally in 2024 — a notable achievement, even as the domestic Chinese equipment ecosystem as a whole remains years behind ASML and Applied Materials in leading-edge capability. China has implemented what industry analysts term a ‘50% Mandate’, requiring domestic fabrication plants to source at least half of their manufacturing equipment from local vendors — a policy with direct and material implications for foreign equipment makers’ addressable market within China, regardless of whatever export licences they might otherwise be able to obtain. China’s 15th Five-Year Plan, covering 2026 to 2030, explicitly prioritises localising core equipment and materials across the entire semiconductor supply chain and developing domestic electronic design automation tools — targets that, while unlikely to bring China to parity with TSMC or Samsung at the absolute leading edge, are explicitly designed to achieve sufficient self-sufficiency to sustain China’s enormous domestic AI and electronics market independent of Western equipment access.
SMIC's Progress Without EUV: What Export Controls Have and Haven't Achieved
The clearest evidence of both the impact and the limits of export controls lies in the demonstrated progress of SMIC, China’s largest domestic chip foundry. The company has achieved measurable progress at advanced process nodes, with its N+2 and N+3 process technologies representing 7-nanometre-class and 5-nanometre-class manufacturing capability achieved entirely without access to ASML’s extreme ultraviolet lithography equipment — a genuinely significant engineering achievement given that EUV lithography has long been considered an essential, non-substitutable technology for manufacturing at these process geometries using conventional techniques. This progress illustrates a consistent pattern that semiconductor industry analysts have increasingly acknowledged: export controls have meaningfully slowed China’s access to the most advanced manufacturing capability and forced costly workarounds, but have not prevented determined, well-resourced domestic engineering efforts from achieving substantial — if not frontier-equivalent — progress, particularly for the mature and near-leading-edge nodes that satisfy the large majority of China’s domestic chip demand.
Domestic U.S. Incentives: The CHIPS Act Tax Credit Push
Even as the Trump administration has been openly critical of the CHIPS Act’s direct subsidy model and has called for elements of it to be repealed, the administration has shown clear support for tax-based incentives as an alternative vehicle to drive continued domestic semiconductor manufacturing investment. Legislative efforts have sought to increase the CHIPS Act’s federal investment tax credit for domestic semiconductor manufacturing investment from 25% to 30%, with the increased credit rate applying to projects that commence construction before the Act’s original 2026 deadline, while explicitly preserving eligibility for projects with long lead times that extend construction beyond that cut-off. This evolving political consensus around tax-based rather than direct-subsidy incentives reflects a broader recalibration of how the U.S. government intends to support continued build-out of domestic fabrication and equipment manufacturing capacity, even as the administration pursues a more confrontational tariff and export control posture toward China specifically.
