US tells ASML it’s concerned China may have top chip tool - The Edge Malaysia

US Commerce Secretary Howard Lutnick raised concerns with ASML executives over the potential entry of extreme ultraviolet (EUV) lithography machines into China, violating US-led export controls. These... Read original →

The U.S. scrutiny of ASML reveals a deeper fracture in global semiconductor control—not just compliance, but technological sovereignty. Even without full EUV systems, if critical subsystems or calibration modules reach China, they could accelerate its immersion DUV-based multi-patterning path toward 3nm-equivalent nodes, eroding TSMC and Samsung’s process leadership. Compliance burdens will inflate ASML’s operational costs and likely extend delivery timelines by over 15%, disrupting NVIDIA and Taiwan, China foundries alike. Competitors like Nikon and Tokyo Electron may leverage U.S.-Japan alignment to capture mid-tier lithography share, while Huawei doubles down on chiplet and 3D stacking workarounds. Over the next 18 months, Washington will expand its tech blockade from tools to materials and EDA, pressuring the Dutch to restrict ArF shipments—ultimately forcing China’s domestic lithography ecosystem toward ‘trusted’ rather than just ‘available’ status, though yield and scale limitations will persist.
