The U.S. Commerce Department ordered American equipment manufacturers to halt specific shipments to Hua Hong last week. The directive targets China’s second-largest chipmaker and its subsidiary, Huali Microelectronics. Affected suppliers include Applied Materials, Lam Research, and KLA Corp.
Washington aims to block China from acquiring 7-nanometer process technology. The restrictions focus on facilities developing advanced semiconductors for artificial intelligence. National security concerns drive this effort to impede China’s advanced chip production.
U.S. equipment suppliers face billions of dollars in potential lost sales. These companies derive a significant portion of their total revenue from the Chinese market. Stock prices for the affected manufacturers fell following the announcement.
