China's Ministry of Commerce has warned that US chip export legislation would disrupt global semiconductor supply chains. The MATCH Act, the Multilateral Alignment of Technology Controls on Hardware, passed the House Foreign Affairs Committee on April 22 as part of what lawmakers described as the largest markup on semiconductor export controls in congressional history. The bill would require the Netherlands and Japan to align their DUV lithography export restrictions with US rules within 150 days or face unilateral US enforcement. It would also cut off ASML’s remaining China sales and ban servicing of existing machines. China has already implemented supply chain security regulations and rare earth restrictions, while the US builds domestic capacity through the CHIPS Act investments and the $25B Terafab project. If implemented, the MATCH act would cut off China’�s access to the DUV immersion lithography machines that ASML still sells there and affect all advanced and near-advanced fabs in the country. The legislation also includes the Chip Security Act requiring advanced chips to include location verification mechanisms before export.
