U.S. Escalates Chip War with Sweeping Tech Restrictions on China
The Biden administration implements expansive export controls that block advanced semiconductor equipment from reaching Chinese chipmakers. The new rules leverage U.S. market dominance to keep China's military technology several generations behind the global leading edge.
The Biden administration implements a sweeping set of export restrictions that severely limits Chinese access to advanced semiconductor chips and manufacturing equipment. These new rules go far beyond previous measures by leveraging U.S. dominance in the semiconductor equipment market to create a choke point against Chinese military advancement.
Specifically, the regulations block the sale of tools required to produce advanced nonplanar transistor designs like FinFET and GAAFET at 14 to 16 nanometers, along with high-density DRAM memory at 18 nanometers or smaller and NAND flash memory with 128 layers or more. By targeting these specific technologies, the U.S. effectively prevents Chinese chipmakers from keeping pace with the global leading edge.
The restrictions halt deliveries by default, forcing foreign companies with Chinese factories like Intel and SK Hynix to apply for specific exemptions to continue operations. Meanwhile, U.S. suppliers like KLA and Lam already halt deliveries and support for existing tools at Chinese firms like Yangtze Memory Technologies, which recently lands on the unverified list alongside 30 other companies.
