The U.S. government is said to be considering further restrictions on China’s access to cutting-edge semiconductor technology. Now, people familiar with the matter say the Biden administration wants to further restrict the gate-all-around (GAA) transistor technology used to manufacture leading-edge chips. The administration is also considering limits on high-bandwidth memory (HBM), which is critical for AI accelerators.
GAA nanosheet transistors improve density while delivering power and performance benefits, but they are only used on the most cutting-edge process nodes. Currently, …
