US bill targets chip tools

A group of U.S. lawmakers wants to cut China off from some of the machines that actually make chips, not just the chips themselves, through a bill called the Multilateral Alignment of Technology Controls on Hardware Act, or MATCH Act, introduced on April 2 with House and Senate sponsors from both parties. (baumgartner.house.gov) The bill goes after two specific tool types: deep ultraviolet lithography machines, which print circuit patterns onto silicon like a stencil, and etching tools, which carve those patterns into the wafer like a chemical chisel. (nbcnews.com) (trendforce.com) That is a sharper move than earlier U.S. controls, because older deep ultraviolet machines were still one of the last legal paths Chinese manufacturers could use to keep pushing into more capable chips. CNBC reported on April 7 that the proposal would ban even those machines. (cnbc.com) The names attached to the fight are not obscure. Reuters reported the draft would affect suppliers such as ASML in the Netherlands and Tokyo Electron in Japan, along with Chinese firms including Semiconductor Manufacturing International Corporation, Huawei, Yangtze Memory, and ChangXin Memory. (usnews.com) The point of the bill is not only to tighten U.S. rules. It also tries to stop a work-around where foreign toolmakers can still sell gear that American companies cannot, by pushing allied governments to line up their export controls with Washington’s. (foreign.senate.gov) (scmp.com) One provision gives those allied countries 150 days to adopt matching restrictions, according to South China Morning Post and TrendForce summaries of the bill. That puts direct pressure on the Netherlands and Japan, because they are home to some of the world’s most important chip-tool companies. (scmp.com) (trendforce.com) Congress has been moving in this direction for years. A Congressional Research Service report published in September 2025 said U.S. policy since 2018 has aimed to slow China’s ability to produce advanced semiconductors and to limit military uses tied to Beijing’s “military-civil fusion” strategy. (congress.gov) The new bill reaches further into the life of machines China already has. TrendForce, citing Chinese industry analysis, said the proposal could also restrict maintenance and technical support, which means a machine sold years ago could become harder to keep running. (trendforce.com) That is why investors immediately looked at ASML. CNBC said ASML had told investors in January that China could account for about 20% of its 2026 sales, down from 33% in 2025, and Reuters reported its shares fell after the U.S. proposal surfaced. (cnbc.com) (msn.com) Beijing answered in political language, not technical language. Xinhua said China accused Washington of harming normal scientific and technological exchanges, which shows this is being framed in Beijing as part of a broader containment campaign rather than a narrow trade dispute. (english.news.cn) The timing also matters because Washington is talking about China on more than one front at once. On April 10, U.S. Trade Representative Jamieson Greer said the United States wants a stable economic relationship with China, but any Chinese involvement with Iran “in a way that is counter to U.S. interests” would complicate that effort. (usnews.com) So this bill is not just about one factory tool or one company order. It is an attempt to turn the chip supply chain into a coordinated gatekeeping system, with the United States trying to make sure the same doors close in California, Veldhoven, and Tokyo at the same time.
