TSMC's Arizona fab reaches yields about 4 points above comparable Taiwan fabs, Bloomberg reports

TSMC/TSMC Arizona

Early production at TSMC's first Arizona fab achieved yields about 4 percentage points higher than comparable Taiwan facilities, according to TSMC's US president Rick Cassidy. The turnaround reversed earlier setbacks from worker shortages and labour disputes.

• TSMC Arizona fab yields roughly 4 percentage points above comparable Taiwan fabs, a significant improvement for semiconductor manufacturing economics.
• Earlier labour challenges resolved through agreements with construction unions, overcoming worker shortages in advanced equipment installation.
• Early yields validate TSMC's US manufacturing expansion strategy, critical for CHIPS Act funding and US semiconductor self-sufficiency goals.
