MATCH Act Tightens Chip Exports
U.S. lawmakers are advancing the MATCH Act, which would broaden export controls on semiconductor equipment and explicitly target DUV immersion lithography and related tools that power foundry and memory production. The bill signals a move to constrain not just bleeding‑edge gear but also the next tier of systems, widening supply‑chain risk for hardware roadmaps (econotimes.com) (asiatimes.com) (chosun.com).
Washington is trying to close the last big door China still uses to buy the machines that make advanced chips. A bipartisan group in Congress introduced the Multilateral Alignment of Technology Controls on Hardware Act on April 2, and Senate sponsors announced their version on April 8. (baumgartner.house.gov) (foreign.senate.gov) The bill is aimed at semiconductor manufacturing equipment, which is the factory gear that prints and etches chip circuits. Lawmakers call these tools a “chokepoint” because a country can design chips on paper and still fail if it cannot buy the machines that turn designs into silicon. (foreign.senate.gov)) The specific machine in the crosshairs is deep ultraviolet immersion lithography, which is the older-but-still-powerful class of tools used to draw tiny patterns on wafers with light. Reuters reported that lawmakers chose it because China still depends on imports in this category, and Dutch company ASML dominates that market with Japan’s Nikon as a smaller rival. (money.usnews.com) That detail matters because current Dutch rules already block ASML’s most advanced extreme ultraviolet lithography systems from going to China, but older deep ultraviolet lines have still been shipping. The new bill would go after those older lines too, along with parts and servicing for the biggest Chinese chipmakers. (money.usnews.com) (asiatimes.com) The company list is not vague. Reuters said the proposal would block sales or servicing for Semiconductor Manufacturing International Corporation, Hua Hong, Huawei, ChangXin Memory Technologies, and Yangtze Memory Technologies. (money.usnews.com) Congress is also trying to solve a different problem at the same time: U.S. firms have faced tighter rules than some foreign rivals. Senate sponsors said the point of the bill is to “harmonize” controls with allies so American toolmakers are not boxed out while Dutch or Japanese suppliers keep selling. (foreign.senate.gov) That is why the bill’s name starts with “Multilateral Alignment.” House sponsors said China has been exploiting gaps between U.S. rules and allied-country rules, and the bill is written to push those countries to move in lockstep instead of leaving a side entrance open. (baumgartner.house.gov) The timing is not random. NBC News reported that China’s imports of semiconductor manufacturing machinery rose from $10.7 billion in 2016 to about $51.1 billion in 2025, which is why Washington now sees factory tools, not just finished artificial intelligence chips, as the real bottleneck to police. (nbcnews.com) The bill also lands right on ASML’s income statement. Reuters reported that China was ASML’s largest market in 2025 at 33% of sales, and ASML said in January that China was expected to fall to about 20% in 2026 even before this new proposal appeared. (money.usnews.com) (asml.com) If this becomes law, the pressure spreads beyond one Dutch supplier. South Korean and Taiwanese chipmakers still running fabs inside China have used those older deep ultraviolet lines too, so a rule that blocks machines, spare parts, and field service would hit production plans, maintenance schedules, and future capacity at the same time. (money.usnews.com) (asiatimes.com) The bigger shift is that Washington is no longer treating “older” chip gear as harmless. The MATCH Act says the next fight is over the machines one rung below the frontier, because those are still good enough to build a lot of foundry and memory capacity if nobody stops the shipments.
