ARM dishes on the future of 20 nm, future nodes.

[Mondozei]

A second keynote on the second day of ISPD-14 was titled "Physical Design and FinFETs." ARM fellow Rob Aitken told the audience: "20 nanometer is the last bulk node, because it has too much leakage. FinFET is a replacement for bulk CMOS, but only for a short term of about three generations."

FinFETs are the best short-term replacement, Aitken said, but something else will replace them in about three generations. To make intelligent architectural decisions today, designers should be investigating FinFET replacements after 2020, because the solutions being considered by different foundries could lead to difficulties in terms of common tools and methodologies.

Pretty interesting stuff. Basically, we need to find new material that's workable and pretty fast. EUV 450 mm at 2023 is a non-starter at this rate.

Probably Si/Ge FinFETs:

And it will be here in 2016, not after 2020.
