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
What happened
US lawmakers proposed a bipartisan bill to ban exports of DUV lithography and etching tools to Chinese entities like SMIC and Huawei. This policy shifts controls from specific fabs to the owning entities, potentially blocking access to advanced equipment for trailing-node and leading-edge fabs. The move signals a tightening of supply constraints for Chinese chipmakers, likely supporting equipment prices.
