Intel Corporation is facing a new wave of scrutiny after evaluating semiconductor manufacturing tools from ACM Research, a California-based equipment firm whose Shanghai and South Korea subsidiaries were added to the U.S. Entity List in 2024.
According to individuals familiar with the matter, Intel tested ACM’s wet etch tools as part of its early preparations for the company’s next-generation 14A node, a process expected to enter production in 2027. While routine qualification of new equipment is common in chipmaking, this particular choice has triggered heightened attention from both regulators and industry analysts.
At the heart of the issue is whether ACM Research’s U.S. business can operate independently of its sanctioned foreign affiliates. The Commerce Department’s Entity List typically restricts not only the listed entities but also foreign companies in which they hold at least 50% ownership.
The ambiguity surrounds more than just equipment purchases. Even if ACM’s U.S. arm is considered legally separate, analysts point out that modern semiconductor manufacturing tools often rely on global support networks.
Questions remain about whether software patches, maintenance services, or hardware components could indirectly involve ACM’s blacklisted units. If such interactions exist, supplying Intel could require export licenses that may not be granted, or may impose delays that are incompatible with Intel’s aggressive roadmap.
This regulatory uncertainty exposes Intel to procurement risks. Should BIS determine that the ACM-Intel interaction violates U.S. restrictions, Intel may be forced to replace the tools mid-development, raising the possibility of costly supply chain adjustments.
The U.S. government placed ACM’s Shanghai and Korean subsidiaries on the Entity List in December 2024 over allegations that they supported China’s military and advanced semiconductor development efforts. ACM has consistently denied the allegations, insisting that its operations comply with U.S. law.
Intel’s decision to evaluate tools associated with these subsidiaries has sparked national security concerns in Washington. Lawmakers argue that even limited cooperation with blacklisted-linked entities risks enabling sensitive technology transfer or undermining U.S. efforts to strengthen domestic chipmaking independence.
Intel has not said whether it plans to adopt the equipment for mass production, noting that tool testing does not automatically guarantee commercial use.
The uncertainty surrounding ACM’s eligibility could have broader consequences for Intel’s 14A timeline. If regulators block ACM from participating, Intel may have to pivot to alternative suppliers, potentially delaying early production milestones.
Moreover, the lack of clear BIS guidance on affiliated entities adds to the industry’s frustration over regulatory unpredictability at a time when U.S. chipmakers are already balancing geopolitical tensions, cost pressures, and rapid technological scaling.
If ACM’s equipment becomes effectively unusable for U.S. chipmakers, the impact could reshape competition in the wafer-cleaning sector. Companies such as SCREEN Holdings, Tokyo Electron, and Lam Research, already leaders in wet-processing and single-wafer cleaning systems, stand poised to capture any displaced market share.
These firms are not affected by the current sanctions landscape and can offer compliant solutions that meet the particle-removal requirements of advanced EUV manufacturing.
Investors are also monitoring cryogenic CO₂ cleaning technologies, which continue to grow at a double-digit CAGR and could become viable alternatives for fabs seeking long-term, sanction-resistant equipment partners.
