Exclusive | TSMC cuts ties with Singapore firm over chip found in Huawei processor: sources
Taiwan Semiconductor Manufacturing Company (TSMC) ended its relationship with PowerAIR, a low-key Singaporean firm, following a client check triggered by the discovery of a TSMC chip in a Huawei Technologies artificial intelligence (AI) processor, three sources said.
PowerAIR is the second known company singled out for possible involvement in the Huawei case. TSMC last year suspended shipments to mainland China-based chip designing firm Sophgo after a chip it ordered from the Taiwanese chipmaker was found to match one on Huawei’s Ascend 910B multi-chip system, according to a Reuters report in October citing unnamed sources.
Chinese tech champion Huawei has been under a blanket ban by the US since 2020 that effectively cuts off its access to semiconductor foundries worldwide. TSMC previously said it had not supplied products to Huawei since 2020. Huawei said it had not produced any chips via TSMC after the US implemented relevant sanctions.
Sophgo and its affiliate, bitcoin mining equipment supplier Bitmain, have denied any business relationships with Huawei.
The Post is unable to reach PowerAIR, which does not have an official website, nor any publicly-listed phone number or email address. TSMC and Huawei did not respond to a request for comment on Thursday.
