“Under the new rule, any foreign company that uses American technology to produce microchips would need a license to sell to Huawei. That makes it difficult for major chip contract manufacturers like Taiwan’s T.S.M.C. to sell to Huawei, because its supply chains rely heavily on American manufacturing tools. It could also clamp down on sales by makers of semiconductor equipment, like Applied Materials and KLA, and chip design software companies like Cadence.”
