Overview
- TSMC's Arizona Fab 21 has officially begun high-volume production of 4nm chips, with yields comparable to its facilities in Taiwan.
- The U.S. facility faces significantly higher costs due to complex regulations, labor shortages, and supply chain challenges, including chemical costs five times higher than in Taiwan.
- TSMC has invested $35 million to establish 18,000 compliance rules to navigate U.S. regulatory requirements, which have doubled construction timelines compared to Taiwan.
- The company confirmed that its most advanced chip technologies, such as N3 and N2 nodes, will continue to be developed and ramped up in Taiwan first due to proximity to R&D teams.
- Products from the Arizona plant, including Apple and AMD chips, are currently shipped back to Taiwan for packaging until a new facility in Peoria, Arizona, is operational.
