Odaily Planet Daily News: The artificial intelligence company Sophgo, associated with Bitmain, stated in a written statement that it has never had any direct or indirect business relationship with Huawei, but also did not deny reports of being cut off from chip supplies by TSMC. In addition, the company stated, "We have provided TSMC with a detailed investigation report to prove that our investigation is unrelated to Huawei." According to reports, the U.S. Department of Commerce initiated an investigation into TSMC earlier this month to confirm whether it provided chips to Huawei, after which TSMC ceased supplying chips to the AI company Sophgo associated with Bitmain. Two insiders stated that 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 it uses U.S. technology in its chip manufacturing process and will comply with U.S. laws. Previously, related news indicated that semiconductor research company TechInsights claimed that after disassembling Huawei's highest-end AI accelerator chip, Ascend 910B, it found that the chip may have been manufactured by TSMC, which also suggests that TSMC may have violated U.S. export controls.
