TSMC has stopped supplying production to China-based Sophgo, which is believed to be a proxy that Huawei used to make its Ascend 910B, Reuters reports. The decision is directly connected with the recent discovery that TSMC supplied Huawei via a proxy despite the U.S. export restrictions.
Reuters says that Sophgo had ordered a chip (allegedly called the Ascend 910B) from TSMC that closely resembled the Ascend 910 processor originally made by TSMC. TechInsights uncovered the 'close resemblance' and issued a paper detailing that the chip was indeed manufactured by TSMC and not by SMIC, as reported at some point previously.
