TSMC: N2 in volume production, A16 (1.6nm with backside power) ramping in H2 2026
Per TSMC's published roadmap and recent updates, the 2nm (N2) node hit volume production in Q4 2025; A16 — 1.6nm with Super Power Rail backside-power delivery — is on track for second-half 2026 production with customer ramp following in 2027. Capacity targeting 70% CAGR through 2028.
TSMC's roadmap progression through 2026: N2 entered volume production in Q4 2025 as planned; N2P (enhanced N2) is scheduled for volume in the second half of 2026; and A16, which combines N2's nanosheet transistors with the Super Power Rail backside-power architecture, is also on track for H2 2026 production. Per TSMC's specs, A16 delivers ~8-10% speed at the same voltage vs N2P, 15-20% lower power at the same speed, and up to 10% density improvement.
Capacity-wise, TSMC has signaled 70% CAGR growth in 2nm and A16 capacity from 2026-2028. NVIDIA is reported as A16's first customer; Apple is rumored to skip A16 and go directly to A14.
Worth noting alongside: industry coverage points at slight slippage in some of TSMC's longer-out roadmap (A12/A13/N2U specs disclosed; A16 schedule depends on customer ramp).
