Fab builds cost $15B–$20B, EUV tools $150M each; TSMC targeting $32B capex
TSM•Advanced 5nm fabs require roughly $15–20 billion in combined construction and equipment costs, with each EUV lithography tool priced above $150 million. TSMC plans to allocate about $32 billion in 2026 capital expenditures to expand 3nm and 5nm capacity in Taiwan and Arizona.
1. Massive capital outlay per advanced fab
Building and outfitting a state-of-the-art semiconductor fabrication plant at the 5nm node costs between $15 billion and $20 billion, driven by cleanroom construction, ultra-pure materials and environmental controls.
2. Equipment dominates costs with pricey EUV tools
Equipment represents about 80% of total fab investment, led by ASML’s EUV lithography machines, each exceeding $150 million, crucial for sub-5nm patterning precision.
3. TSMC’s 2026 capex commitment and strategic impact
TSMC has earmarked approximately $32 billion in 2026 capital expenditures to develop new 3nm and 5nm fabs in Taiwan and Arizona, aiming to boost advanced-node output and reinforce its market leadership.
