800 nm process

From Wikipedia the free encyclopedia

The 800 nanometer process (800 nm process) is a level of semiconductor process technology that was reached in the 1989–1990 timeframe, by most leading semiconductor companies, such as Intel, ATI Technologies, and IBM.[1]

Products featuring 800 nm manufacturing process[edit]

  • 50-MHz i486DX CPU launched in 1991 was manufactured using this process.[2]
  • microSPARC I launched in 1992
  • First Intel P5 Pentium CPUs at 60 MHz and 66 MHz launched in 1993
