On Friday, the US announced a new set of semiconductor export restrictions aiming at cutting China off from accessing certain high-end chips and further limiting the country’s ability to try to make advanced chips themselves.
The Department of Commerce’s Bureau of Industry and Security of the US issued nine new rules, detailing that new rules aims to impose export controls on advanced chips, transactions for supercomputer centers, and transactions involving certain entities on the Entity List. In addition, the new rules also impose new controls on certain semiconductor manufacturing equipment and on transactions for certain integrated circuit end uses.
These rules will be less strict on firms “owned by multinationals,” according to the file. Twenty-eight Chinese entities on the US’s Entity List are affected by the expanded rules, most of which are supercomputer institutions and AI firms. Some new rules take effect immediately, with others effective before Oct. 21.
The US’s Bureau of Industry and Security adds 31 new Chinese entities to an “Unverified List,” including major Chinese memory chip maker YMTC. Firms that tend to export or transit products listed on the Commerce Control List to China now have to ask permission from the US. Entities listed on the Unverified List are one step away from being added to the Entity List if they do not meet the US’s requirements within 60 days.
These new rules follow a months-long effort of the US trying to contain China’s ability to obtain advanced chips and chipmaking tools. Since July, the Biden administration has barred Chinese chipmaking firms from acquiring tools for 14 nm and more advanced chips, focusing heavily on central logic chips like CPUs and GPUs. Since August, the US has also considered broader restorations in fields such as memory chips as major Chinese chipmakers YMTC and SMIC continue to develop their own chips.
Below, TechNode summarizes the key moments from the US’s attempts to hobble China’s semiconductor industry since July.
July 6 – Lithography machinery
July 30 – Tools to make 14 nm chips
August 2 – Memory chips
August 12 – EDA software
August 31 – High-performance GPU chips
September 21 – Nvidia looked to bypass US ban, providing alternative GPU to China
