US lawmakers raise concerns about Intel’s testing of tools from China-linked firm

WASHINGTON: A bipartisan group of U.S. lawmakers led by Democratic Senator Elizabeth Warren and Republican Tom Cotton on Wednesday raised national security concerns over Intel’s testing of chipmaking tools made by ACM Research, as first reported by Reuters.

ACM Research, California-based producer of chipmaking equipment, has deep roots in China and two overseas units that were targeted by U.S. sanctions. Its customers include sanctioned Chinese companies such as YMTC ‌and SMIC, sparking questions ⁠over whether ⁠ACM could pass sensitive information from Intel to Chinese customers, the lawmakers said.
