WASHINGTON, Jan 15 (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. ( TSM )

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 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.
