Intel said to test tools from firm with sanctioned China unit

Intel has tested wet etch tools from ACM Research, a California-based firm with units in China and South Korea that are under US sanctions, according to sources familiar with the matter.

The tools were evaluated for possible use in Intel’s advanced 14A chipmaking process, set to launch in 2027.

ACM’s Shanghai and South Korea units were added to a US export blacklist in 2024 over concerns about their support for China’s military and advanced chipmaking efforts, allegations which ACM denies.

Intel’s decision to test equipment from a firm with sanctioned units has raised national security concerns among US policymakers, who cite risks related to technology transfer and the possible displacement of Western suppliers.

ACM said its US operations are separate from its sanctioned Chinese unit and that it maintains safeguards to protect customer trade secrets.

Intel has not disclosed whether it will use ACM’s equipment in its manufacturing process.

🧠 Food for thought

Implications, context, and why it matters.

Intel’s ACM testing hinges on unclear export rules for affiliated entities

A key question is whether ACM Research’s California unit can supply Intel without Bureau of Industry and Security (BIS) limits 1. ACM Research (Shanghai), Inc. and its Korean units landed on the Entity List, a U.S. export blacklist, in December 2024 1.
Entity List rules cover foreign entities owned 50% or more by listed parties 2, while ACM says its US arm is separate from Shanghai 1. This raises the question of whether tool builds, software updates, or field service pass through the sanctioned affiliates, which would drive license needs under BIS rules.
BIS guidance on affiliated entities in the Federal Register lacks clarity, so Intel faces procurement risk. If BIS reads ACM’s structure as needing licenses, wet etch tools tested for Intel’s 14A process in 2027 may not be viable. Intel would then qualify other suppliers, which could delay advanced node ramps.

Compliant wet cleaning suppliers can capture displaced share

If ACM gear gets restricted, other wafer cleaning and wet-process tool makers can gain share at US and European fabs. Names include SCREEN Holdings (Japan), Tokyo Electron (Japan), and Lam Research (US) 3. Single-wafer cleaning held 33.2% revenue share in 2024 3.
Vendors should pursue Intel’s 14A qualification and advanced node fabs with contamination control data for sub-10 nm particle removal needed for extreme ultraviolet (EUV) lithography 3. Asia-Pacific had 72.5% of the wafer cleaning market 3, so Western tool makers can pitch sanction-compliant options.
Components suppliers and investors can map installed base leaders in wet cleaning to steer capital to firms with records in automated platforms and cryogenic CO2 systems (which use carbon dioxide at very low temperatures for particle removal) 3. These systems post a 12.2% compound annual growth rate (CAGR) 3, so partnerships can form before qualification cycles lock in equipment choices.
