TechFlow news, on October 26, according to The Information, the U.S. Department of Commerce launched an investigation into TSMC earlier this month to determine whether it had supplied chips to Huawei. Subsequently, TSMC halted chip deliveries to Sophgo, an AI company linked to Bitmain. Two people familiar with the matter said TSMC has cut off chip supplies to the relevant companies. Since 2020, Huawei has been banned from purchasing chips made using U.S. technology, including those produced by TSMC. TSMC stated that its chip manufacturing process involves U.S. technology and affirmed its commitment to comply with U.S. laws.
Earlier reports indicated that semiconductor research firm TechInsights claimed, after reverse-engineering Huawei's current most advanced artificial intelligence (AI) accelerator chip, the Ascend 910B, that the chip might have been manufactured by TSMC—suggesting TSMC may have violated U.S. export controls.
