On August 31, 2026, TSMC and Amkor Technology announced a definitive agreement to collaborate on advanced packaging and testing services in Arizona. This partnership will integrate TSMC’s front--end wafer fabrication at its Phoenix fabs with Amkor’s planned back--end facility in Peoria, specifically focusing on CoWoS (Chip on Wafer on Substrate) and InFO (Integrated Fan--Out) technologies.
Key Strategic Implications:
- Supply Chain Localization: Establishes the first comprehensive, U.S.--based "one--stop" manufacturing cycle for AI and high--performance computing (HPC) chips.
- Lead Time Reduction: Minimizes logistical delays by eliminating the need to ship wafers back to Asia for advanced packaging.
- Customer Demand: Directly addresses requirements from major U.S. clients for a geographically resilient and domestic semiconductor ecosystem.
