There's also some word about 7nm and EUV:
As for TSMC's 7nm process development, volume production is set to kick off in 2018. The company has had 13 7nm tape-outs for mobile devices, with about half of the tape-outs for HPC designs, Wei said. The process has also received positive feedback from customers specializing in the development of mid-range and high-end smartphone chips, according to Wei.Via: DigiTimes
TSMC has also been engaged in R&D for an improved version of the 7nm process using extreme ultraviolet (EUV), which will be ready for volume production in 2019, said Wei. As for 5nm, risk production is scheduled to start in the first quarter of 2019, Wei indicated.
