TSMC prepares for 3nm mass production at Arizona fab in late 2027
Sunday, March 29, 2026 at 03:16 AM
TSMC is preparing to begin mass production of 3nm chips at its Arizona fabrication plant in the second half of 2027. This expansion is expected to increase N3 production capacity by approximately 30,000 wafers per month.
Context
Recent reports indicate that TSMC is accelerating its expansion in the United States, with its second Arizona fabrication plant (Fab 21 Phase 2) now expected to begin mass production of 3nm chips by the second half of 2027. This timeline reflects an effort to compress construction schedules from the original 2028 target, as the company gains experience with local regulations and project management. The phase is anticipated to add approximately 30,000 wafers per month in capacity, significantly bolstering the domestic supply of advanced silicon.
This development is part of a massive $165 billion total planned investment by TSMC in Arizona, which includes six fabs and advanced packaging facilities. The site has already achieved volume production of 4nm chips at its first fab as of late 2024. By bringing 3nm capabilities online sooner, TSMC aims to better serve key U.S. customers like Apple, NVIDIA, and AMD who are driving a surge in demand for high-performance AI and data center hardware.
