350 nm process

The 350 nm process refers to the level of MOSFET semiconductor process technology that was reached around the 1993–1996 timeframe, by leading semiconductor companies like Sony, Intel and IBM.

A MOSFET with a 300 nm channel length was fabricated by a research team led by K. Deguchi and Kazuhiko Komatsu at Nippon Telegraph and Telephone (NTT) in 1985.[1]
