6 μm process

The 6 μm process (6 micrometers) is the level of semiconductor process technology that was reached around 1974^[1][2] by companies such as Intel.

The 6 μm 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 6 micrometers wide.

Products featuring 6 μm manufacturing process

• Intel 8080 CPU launched in 1974 was manufactured using this process.^[3]
• Zilog Z80 launched in 1976 was manufactured in 4 μm.^[4][5]
• Intel 2116 and Mostek 4116 16K DRAMs were introduced in 1975 and 1976, respectively. ^[6]
