US tells ASML it's concerned one of its chipmaking tools may be in China: Report - ET Telecom

This development highlights the complex interplay between global semiconductor supply chains and geopolitical tensions, particularly between the US and China. The US government's concern over potentia... Read original →

Washington’s scrutiny of ASML stems less from a single tool’s whereabouts and more from fear that EUV-enabled sub-3nm capabilities could proliferate beyond U.S. control. If Chinese foundries gain even indirect access, it erodes the leverage of American EDA, IP, and equipment ecosystems. Compliance burdens now extend beyond paperwork into full supply-chain redesign—evident in TSMC’s stalled Nanjing expansion. In response, ASML may push DUV multi-patterning as a regulatory workaround, but at significant cost and yield penalties for Chinese clients. Over the next 18 months, expect intensified U.S.-led export controls with Japan and the Netherlands, while China doubles down on immersion lithography and chiplet-based scaling to bypass EUV dependency. Geopolitical risk is no longer a footnote—it’s now priced into every semiconductor capex decision.
