TSMC's A16 1.6nm process is expected to start mass production in the fourth quarter of 2026

According to reports from Liberty Times and other media, TSMC has completed the development and verification of the angstrom-level A16 (1.6nm) process, which is expected to enter mass production in the fourth quarter of 2026. This process uses TSMC's back-end power delivery network technology Super Power Rail (SPR), separating signal routing from power routing, with the power located on the back of the wafer to reduce bottlenecks.

Compared to the 2nm process, the A16 is said to improve computing speed by 8% to 10%, reduce energy consumption by 15% to 20%, and increase chip density by 8% to 10%. TSMC views the 1.6nm process as a transitional step towards 1.4nm, with the goal of starting 1.4nm mass production in 2028.
