US Senators Press Intel Over Ties to Firm With Sanctioned Units

A bipartisan group of six US senators pressed Intel Corp. for more information about its relationship with ACM Research Inc., a maker of semiconductor equipment whose subsidiaries remain on a Commerce Department blacklist, following a 2024 listing for national security reasons.

In a letter addressed to Intel Chief Executive Officer Lip-Bu Tan, the senators cited a Reuters report from December that the chipmaker had tested equipment from ACM used to create precise patterns in semiconductors. The lawmakers said that ACM units based in Shanghai and South Korea have previously done work with Chinese companies that the Pentagon has publicly connected to China’s military, including Semiconductor Manufacturing International Corp., Yangtze Memory Technologies Co. and ChangXin Memory Technologies Inc.
