The Taiwan Semiconductor Manufacturing Co. is officially producing advanced manufacturing chips in Phoenix, the company confirmed on an overnight earnings call. Why it matters: According to U.S. Commerce Secretary Gina Raimondo,

Apple's first batch of 'Made in USA' chips from TSMC Arizona are in the 'final test stage' chips being tested against 'Made in Taiwan' variants.

TSMC's N2 (2nm) process node is "well on track" for volume production in the second half of 2025, as scheduled, Wei said. This is expected to offer a 10 to 15 percent speed improvement at the same power versus N3E technology, or a 20 to 30 percent power improvement at the same speed, and an increase of more than 15 percent in density.

Taiwan Semiconductor Manufacturing Co has begun producing advanced four-nanometer chips for U.S. customers in Arizona, Commerce Secretary Gina Raimondo told Reuters, a milestone in the Biden administration's semiconductor efforts.

Apple is already testing the initial batch of processors produced for its devices by TSMC Arizona, reports Nikkei Asia. To begin with, the tests intend to compare the Arizona output to see if the quality is similar to chips produced in TSMC’s cutting-edge fabs in Taiwan.

TSMC's chip foundry in Arizona is not just making one Apple chip, as a second Apple design is reportedly now in production at the facility.
