A bipartisan group of U.S. senators has proposed a new law that would impose an almost blanked ban on exports of advanced wafer fabrication equipment (WFE) to select entities in adversary nations, a rule that would complement the existing fab-based bans. If imposed, leading China-based chipmakers like CXMT, Hua Hong, SMIC, and YMTC would lose the ability to procure advanced tools for outdated fabs and use them to advance their leading-edge facilities.
