The 3 μm process is the level of MOSFET semiconductor process technology that was reached around 1977,[1][2] by leading semiconductor companies such as Intel.
Products featuring 3 μm manufacturing process
- Intel's 8085, 8086, 8088 CPU's launched in 1976, 1978, 1979, respectively, were manufactured using its 3.2 μm NMOS (HMOS) process.[1] [failed verification].[3][dubious ]
- Hitachi's 4 kbit HM6147 SRAM memory chip, launched in 1978, introduced the twin-well CMOS process, at 3 μm.[4]
- Motorola 68000 (MC68000) CPU, launched in 1979, was originally fabricated using an HMOS process with a 3.5 μm feature size.[5][circular reference]
- The ARM1 was launched in 1985 and manufactured on a 3 μm process.[6]
