TSMC’s Arizona Trials Put Plant Productivity on Par with Taiwan

Taiwan Semiconductor Manufacturing Co. achieved production yields at its Arizona facility on par with established plants back home, an early indicator that its marquee US project is on track to achieve its targets.

The Taiwanese chipmaker’s yield rate in trial production at its first advanced US plant is similar to comparable facilities in the southern Taiwanese city of Tainan, according to a person familiar with the company, who asked not to be identified discussing private corporate matters. TSMC had said it started engineering wafer production in April with advanced 4-nanometer process technology.
