1 µm process

From Wikipedia, the free encyclopedia

The µm process refers to the level of semiconductor process technology that was reached around the 1984–1986 timeframe,[1][2] by leading semiconductor companies like NTT, NEC, Intel and IBM. It was the first process where CMOS was common (as opposed to NMOS).

Products featuring 1.0 µm manufacturing process[edit]

  • NTT introduced the 1 µm process for its DRAM memory chips, including its 64 kb chip in 1979 and 256 kb chip in 1980.[3]
  • NEC's 1 Mb DRAM memory chip was manufactured with the 1 µm process in 1984.[4]
  • Intel 80386 CPU launched in 1985 was manufactured using this process.[5]
