6 µm process

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

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]
