TSMC Ramps Five 2nm Plants to Double AI Chip Capacity

TSMC is doubling its advanced-node capacity expansion to address explosive demand for artificial intelligence and high-performance computing. The company is ramping up five 2nm fabrication plants simultaneously in 2026, marking its most aggressive expansion effort to date.

Total capacity output for the 2nm process is projected to be 45% higher than that of 3nm facilities at the same production stage. Although the 2nm process utilizes a complex nanosheet architecture, it entered mass production in the fourth quarter of 2025 with yields that reportedly outperform the previous 3nm generation.

To sustain this scale, the company intends to install nine new factories and execute capacity conversion projects annually. This expansion includes existing sites in Arizona, USA; Kumamoto, Japan; and Dresden, Germany. Simultaneously, the manufacturer is developing its next-generation A16 node, which will feature backside power delivery.
