Intel tested chipmaking tools from ACM Research, a firm with sanctioned units in China and South Korea, for its advanced chipmaking process. Concerns arise over national security implications and potential technology transfer to China. U.S. lawmakers reintroduce legislation to block chipmakers from using Chinese equipment. ACM denies allegations and highlights its U.S. operations’ safeguards against national security threats.

ACM Research, founded by an American citizen with Chinese permanent residence, sells equipment to sanctioned Chinese chipmakers and has significant ties to China. Most of ACM’s research and development take place in China, with a new facility recently opened in Oregon’s ‘Silicon Forest’ near Intel’s flagship plant. ACM aims to expand outside China through global engagements.

ACM is a minor player on the global semiconductor equipment market but is gaining market share in China’s push for semiconductor self-sufficiency. Chinese tools are cheaper than rivals, creating pricing pressure on established competitors. Intel tested ACM’s tools, raising concerns about technology transfer and national security risks. Lawmakers push to block chipmakers from using Chinese equipment.
