Taiwan Semiconductor Manufacturing Co. reports higher production yields at its Arizona plant compared to similar facilities in Taiwan, according to Rick Cassidy, president of TSMC’s US division.

The company revealed in a recent webinar that the Arizona facility yields are approximately 4 percentage points higher than those in Taiwan.

The Phoenix plant began trial production using 4-nanometer technology earlier this year.

The progress is significant given the initial labor shortages and safety issues that delayed the plant’s timeline.

Originally slated for full production by 2024, the target has shifted to 2025.
