US lawmakers scale back bill targeting Chinese chipmaking

A US bill to keep more chipmaking equipment from China has been scaled back, ​according to the latest version seen by ​Reuters, but still includes a new countrywide restriction on ASML’s deep ultraviolet (DUV) immersion lithography ​machines.

Netherlands-based ASML, by far the world’s dominant supplier of the critical technology, declined to comment.

The “MATCH Act” was introduced in the U.S. House of Representatives on April 2 with bipartisan support, to close gaps in restrictions on chipmaking equipment sold to China and align the U.S. ‌and other countries, ⁠including Japan ⁠and the Netherlands.
