As TSMC Arizona is manufacturing under an N4 four-nanometer process to make the A16 chip already, and the S9 is derived from the A16, it makes sense for this SiP to be made at the same facility. TSMC finally started to produce chips at its Arizona foundry, which had been under construction since 2020. Four months later, the facility is seemingly expanding its capabilities.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. Is TSMC dominating the chip industry ?
