MATCH Act: How New U.S. Chip Legislation Could Freeze China's Semiconductor Ambitions

American lawmakers are advancing one of the most aggressive semiconductor export control bills ever proposed. The Multilateral Alignment of Technology Controls on Hardware Act, widely known as the MATCH Act, has drawn sharp attention from Bernstein analysts who describe it as significantly stricter than any prior restriction — one that could effectively lock China's advanced chipmaking capacity at its current level while making it nearly impossible to maintain existing equipment.

At the core of the legislation is a blanket national prohibition on selling advanced immersion Deep Ultraviolet lithography systems to China, covering tools from manufacturers like ASML and Nikon, along with cryogenic etch equipment. What sets this bill apart from earlier measures is its elimination of any remaining licensing workarounds that companies previously relied on. It also invokes the Foreign Direct Product Rule to legally compel allied nations, particularly the Netherlands and Japan, to align their export policies with U.S. standards within 150 days, replacing inconsistent diplomatic agreements with a hard statutory deadline.

Five Chinese companies face the harshest consequences under the bill: SMIC, CXMT, YMTC, Hua Hong, and Huawei. Because these firms are named directly in the legislative text, their restrictions fall outside administrative review. Foreign vendor engineers would be barred from servicing or repairing tools already operating inside these facilities, U.S. personnel would be prohibited from offering any technical support globally, and license applications would be categorically denied with no room for individual case reviews.

Although China's recent $30 billion investment in lithography equipment may sustain some capacity growth through 2027, analysts believe the MATCH Act would ultimately confine future production to older 65/55nm process nodes. The legislation could also push Beijing to accelerate domestic chipmaking alternatives, though likely at the expense of production yields and overall efficiency.
