According to reports on November 21, Chang Chung-mou ，ounder of Taiwan Semiconductor Manufacturing Company (TSMC), said that the company planned to produce advanced 3-nanometer technology chips in a new factory in Arizona, USA, but the plan has not yet been fully finalized. TSMC, a major Apple supplier and the world’s largest foundry chipmaker, is building a $12 billion factory in Arizona. Chang Chung-mou said that both the 5nm and the 3nm plants will be set up at the same location in Arizona, with the former being the first stage and the latter being the second stage. TSMC will hold the arrival ceremony of its first batch of manufacturing equipment on December 6 in Arizona. Chang will be joined by TSMC customers and suppliers, as well as U.S. Secretary of Commerce Gina Raimondo. Taiwan’s dominance as a manufacturing center for chips used in smartphones, automobiles and fighter jet technology has raised concerns about the world’s over-reliance on it, especially amid CCP’s growing military pressure and saber-rattling. The U.S. and Europe have passed bills and provide billions of dollars in incentives for semiconductor manufacturers to produce chips closer to home. In the long run, TSMC’s investment in the U.S. is Washington’s necessary move to ensure the security of the supply chain.
