Chinese technology news site Moore reported (May 19) that the Taiwan Semiconductor Manufacturing Company (TSMC) received a US$ 700 million emergency order from Huawei on May 18. However, sources from Japan said TSMC has refused that order. TSMC is the world’s largest chip-maker and manufactures most of Huawei’s critical high-end chips. On May 15, the U.S. Department of Commerce released new regulations on approval requirements for manufacturers using U.S. technologies. The new rules will effectively ban any suppliers from helping Huawei. TSMC just reached an agreement with the U.S. government and announced a plan to construct a new cutting-edge 5nm chip manufacturing facility in Arizona. The Chinese government has already threatened retaliation against U.S. high-tech companies.
