Currently N3, which entered volume production in Q4 2022, is the most advanced process.
Following it up is N3E which has passed technology qualification and achieved its performance and yield targets. It has received the first wave of customer product tape-outs and will start volume production in the second half of 2023.
The number of new tape–outs for N3E is 1.5 to 2X that of N5 over the same period.
