The MATCH Act and China’s DUV Imports

Deep Ultraviolet (DUV) lithography serves as a critical strategic choke point in the U.S.-China AI competition, as it remains the most difficult semiconductor manufacturing technology for China to indigenize. Guest Nick Brown, co-founder of the Center for Technology and Statecraft, highlights a significant "cannonball-sized hole" in current export controls that allows China to import vast quantities of DUV immersion systems, potentially enabling parity in advanced chip production within a decade. The proposed MATCH Act seeks to close this gap by mandating countrywide controls on semiconductor manufacturing equipment and aligning allied export policies with U.S. standards. While China’s current stockpile of lithography tools is insufficient to match U.S. AI chip production through 2035, continued imports threaten to erode this advantage. Restricting equipment exports and servicing at advanced fabs remains a necessary, long-term strategy to maintain a decisive lead in global computational power.
