Overview
- TSMC confirmed its N2 technology entered mass production in Q4 2025, with initial output at Fab 22 in Kaohsiung using a nanosheet transistor structure for performance and power gains.
- Local reports say 2nm production is also underway at Fab 20 in Hsinchu, though the company’s statement specifically cites Kaohsiung.
- Reporting indicates Samsung is retooling its Taylor, Texas facility to jump from a planned 4nm ramp to 2nm GAA and raising its initial target to about 50,000 wafers per month, with mass production in 2026 described as the goal and a large Tesla order cited but not confirmed.
- Industry reports say TSMC is moving up 3nm mass production in Arizona to 2027 to meet demand and counter rivals, tightening the gap between U.S. and Taiwan capacity.
- Analysts note only a handful of firms can produce at the 2nm class, and Taiwanese officials reiterate that the island intends to keep the most advanced chipmaking at home despite overseas fab investments.
