TSMC's 1.6nm-Class A16 Process Enters Volume Production
- TSMC's 2026 roadmap lists A16 as a 2027 technology; Kevin Zhang said "A16 will be ready for production in 2026. However, actual product ramp depends on customers, and we expect volume production to begin in 2027"[1]
- A16 is essentially N2P with Super Power Rail backside power delivery, aimed at AI and HPC data-center chips; A12, due in 2029, succeeds it[1]
- Moving power rails to the back of the wafer frees front-side routing for signals and cuts IR drop; against N2P, A16 gives 8-10% more speed at the same Vdd, 15-20% less power at the same speed and up to 1.10x chip density[2]
- TSMC's A16 page still says the node "will be production-ready in 2H26"[2]
- TSMC unveiled A16 at its 2024 North America Technology Symposium "for planned production in 2026"[5], and in November 2024 said it remained on track for late 2026[4]
- TrendForce reads the 2026 roadmap as A16 volume production "delayed to 2027"[3]

TSMC's[2][5] Kevin Zhang told Tom's Hardware "A16 will be ready for production in 2026... we expect volume production to begin in 2027", and TSMC's roadmap slide lists A16 under 2027; with no quarter named, the year's last day stands in.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
