On April 23rd, the U.S. House Foreign Affairs Committee passed the MATCH Act, escalating the U.S. chip war against China


- MATCH: Multilateral Coordination Act for Hardware Technology Controls
- Core goal: Shift from "I won't sell to China" to "Force all allies to stop selling to China."
Three strategies:
- Ban equipment: Fully prohibit the sale of key semiconductor manufacturing equipment such as DUV lithography machines and low-temperature etching machines to China, including equipment maintenance, software upgrades, and parts replacement.
- Name five companies: SMIC, Huawei, Yangtze Memory Technologies, Hefei Changxin, and Huahong Semiconductor and their subsidiaries are included in "Controlled Facilities," effectively an expanded entity list, cutting off supply of both new and old equipment.
- Pressure allies to choose sides: Require allies like the Netherlands and Japan to align their semiconductor export controls to China with U.S. standards within 150 days. Non-compliance may invoke the "Foreign Direct Product Rule"—any technology, software, or parts using U.S. technology are subject to U.S. controls.
Additional steps needed for implementation:
- Full House vote in the House (committee has approved, awaiting full chamber vote)
- Senate passage of a supporting bill (a version already exists in the Senate, possibly added as an amendment to the National Defense Authorization Act (NDAA))
- Reconciliation of the two chambers' versions (if there are differences, negotiations are required)
- Presidential signing into law
- Estimated timeline: High likelihood of enforcement in the second half of 2026
Core promoters:
Micron, fearing China will dominate storage chips as it does solar energy.
Impacts:
- ASML is most affected, with about 36% of its revenue coming from mainland China
- Tokyo Electron, Lam Research, Applied Materials, and KLA are lobbying against it
- Acquisition of DUV equipment for China's 28nm mature process has been significantly restricted; existing equipment is breaking down without repairs, accelerating domestic substitution
