Micron backs tougher U.S. export curbs on China chipmaking equipment

Micron Technology has moved into the center of Washington’s fight over China’s chipmaking capacity, backing a bill that would tighten export restrictions on the equipment and servicing that keep advanced fabs running. The proposal, called the MATCH Act, would close gaps in current controls and would hit Chinese chipmakers including ChangXin Memory Technologies, Yangtze Memory Technologies Corp. and Semiconductor Manufacturing International Corporation, while also raising the stakes for foreign suppliers that service those plants.

The House Foreign Affairs Committee advanced the bill on April 22, one day after the push drew new attention. Rep. Michael Baumgartner introduced the measure in the House on April 2, with House Select Committee on China Chair John Moolenaar among the original cosponsors and a bipartisan group joining him. A Senate companion was introduced by Sens. Pete Ricketts and Andy Kim. During the drafting process, Micron CEO Sanjay Mehrotra held closed-door roundtables with members of the House Foreign Affairs Committee and Senate Banking Republicans, underscoring how directly the company has engaged in shaping the policy.

The bill’s scope is broad. It would target additional semiconductor manufacturing equipment, including certain DUV immersion machines, and require licenses for service work at covered facilities. The text names a long list of Chinese companies, including Huawei, Hua Hong Semiconductor, Advanced Micro-Fabrication Equipment Inc. China, NAURA Technology Group, Piotech Semiconductor Equipment, ACM Research, PNC Process Systems, Skyverse Technology, Shanghai Micro Electronics Equipment, Kingsemi and Hwatsing Technology. Analysts at the Center for a New American Security said the measure would prohibit the sale and servicing of critical chipmaking tools to advanced fabrication facilities in China, including deep ultraviolet immersion lithography and cryogenic etch systems.

That is where national security and corporate self-interest meet. Micron is the largest U.S. memory chipmaker and the only major U.S. supplier in a market dominated by Samsung Electronics and SK Hynix. Tougher controls could make it harder for Chinese rivals to climb the memory ladder, preserving an advantage for the lone U.S. player while giving Washington more leverage over a strategic technology. But the same policy would also force allied firms such as ASML to seek licenses before servicing equipment at covered sites, pulling the Netherlands and other partners into the dispute.

China has spent tens of billions of dollars on domestic chip support since its 2015 Made in China 2025 strategy, and the MATCH Act is designed to slow that drive by constraining the tools, upgrades and repairs that make modern fabrication possible. What Washington is weighing now is whether that is a necessary security response, or a policy sharpened by an industry that knows exactly who benefits when China’s chipmakers hit a wall.
