US Bill Aims to Kill DUV Chip Tool Exports to China
The MATCH Act would ban DUV lithography exports to China, targeting a critical AI supply chain chokepoint.
New legislation called the MATCH Act wants to slam the door on exporting deep ultraviolet (DUV) lithography technology to China. The bill would expand existing restrictions on chipmaking tools, hitting a crucial bottleneck in semiconductor manufacturing that underpins the entire AI industry.
The numbers tell the story of why Washington is nervous. China's imports of chipmaking equipment have ballooned from $10.7 billion in 2016 to roughly $51.1 billion in 2025. That's nearly a 5x increase in under a decade.
DUV lithography sits at the heart of chip fabrication. Without it, producing advanced semiconductors becomes nearly impossible. The proposed ban would cover exports of certain manufacturing tools across China, tightening what's already a heavily restricted trade corridor.
This is the latest move in an escalating tech cold war over who controls the future of chip production.
