US lawmakers aim to ban export of DUV chipmaking and etching tools to leading firms in China — bipartisan proposal would ban lithography equipment for Huawei, SMIC, and others

A bipartisan group of U.S. senators has proposed a law to ban the export of advanced wafer fabrication equipment to select entities in adversary nations like China, affecting chipmakers such as Huawei and SMIC. The proposed MATCH Act aims to shift export controls from fab-based to company-based, preventing entities from accessing U.S. technology for advanced chip production. The bill introduces a 75% threshold to limit controls to crucial technological chokepoints. While it may not eliminate all leakage, the act seeks to disrupt reliable supply chains used by Chinese entities to obtain advanced fabrication equipment. The goal is to maintain strategic leverage and potentially relax restrictions if domestic alternatives reach sufficient scale.
