Taiwan Semiconductor Manufacturing Co. discovered this month that chips it made for a specific customer ended up with Huawei Technologies Co., a potential violation of US sanctions intended to sever the flow of technology to a Chinese national champion.
TSMC halted shipments to the client around mid-October after it realized semiconductors fabricated for that entity had found their way into Huawei products, a person with direct knowledge of the matter said. The chipmaker has since notified the US and Taiwanese governments and is investigating the matter more thoroughly, the person said, asking not to be identified discussing a sensitive situation.
