U.S. Expands Ban on Sales of Chipmaking Gear to China

A recent expansion of U.S. restrictions on China’s access to chipmaking technology will have a broad impact on the Chinese semiconductor industry, analysts said.

American authorities broadened their ban on sales of chipmaking equipment to China, according to Tim Archer, the chief executive officer of Lam Research Corp., a California-based supplier of silicon wafer fabrication gear. After previously barring shipments of machinery to produce advanced technology nodes of 10 nanometers or less, the U.S. expanded the restrictions to apply to chips of up to 14 nanometers, Archer said.
