800 nm process

The 800 nm process (800 nanometer process) is a level of semiconductor process technology that was reached in the 1987–1990 timeframe, by companies, such as Intel, ATI Technologies, and IBM.^[1]

The 800 nm process refers to the minimum size that could be reliably produced. The smallest transistors and other circuit elements on a chip made with this process were around 800 nanometers wide.

Products featuring 800 nm manufacturing process

• 50-MHz i486DX CPU launched in 1991 was manufactured using this process.^[2]
• Both 25/50 and 33/66 MHz Intel486 DX2 CPU using this process.^[3]
• Early version of Intel486 SX2 using this process.^[4]
• microSPARC I launched in 1992
• First Intel P5 Pentium CPUs at 60 MHz and 66 MHz launched in 1993
