The 350 nanometer process is a level of semiconductor process technology that was reached in the 1995–1996 timeframe
The new stuff is 3nm
350 nm is massive and ancient relative to new processes, but the name of a new process stopped physically meaning anything a while ago. for instance, the 3 nm process smallest distance between traces is only 24 nm.
now the industry just names a new process when enough techniques for improving performance (without much actual size difference) exist.
