WASHINGTON (Reuters) -The Biden administration added more than a dozen Chinese entities to its restricted trade list on Wednesday, including a company whose TSMC-made chip was illegally incorporated into a Huawei artificial intelligence processor.
Sophgo and other entities linked to it were among 14 China-based companies and two Singapore-based companies added to the U.S. Commerce Department’s Entity List, according to a federal government notice. Companies on the list cannot receive goods or technology exports without a license, which is generally denied.
Sophgo drew attention after a chip found on Huawei’s Ascend 910B multi-chip AI system matched one it ordered from Taiwan Semiconductor Manufacturing Co.
Sophgo is among numerous companies that have been punished by the U.S. for helping Huawei. Late last year, the Commerce Department added other companies viewed as part of Huawei’s shadow network to the U.S. Commerce Department’s restricted trade list.
The U.S. also on Wednesday strengthened restrictions on advanced computing semiconductors, including chips used for AI, to stop them from reaching China.
The new rules impose broader curbs for chip factories and packaging companies seeking to export certain advanced chips, building on earlier measures aimed at hampering China’s access to chips for its military.
The new controls affecting chips at 14 or 16 nanometer nodes or below that can be used in AI applications, and impact companies beyond TSMC.
Samsung (KS:) sales may also be affected. Neither TSMC nor Samsung immediately responded to requests for comment.
Chipmakers can bypass licensing requirements if certain conditions are met, such as working with an approved designers and trusted chip packagers.
