TSMC halts chip supply to customer after finding it in Huawei product, source says

Taiwan Semiconductor Manufacturing Co has suspended shipments to a customer after it discovered that one of its chips supplied to the client ended up in a Huawei product, according to a Taiwan official familiar with the situation. About two weeks ago, TSMC suspended shipments to the client and began a detailed investigation, the trade and economic official said, speaking on condition of anonymity given the sensitivity of the situation. The company has notified the U.S. and Taiwanese governments, the official said as it was an “important warning event” within TSMC, and can, at its earliest, be traced back to Oct. 11.
