6 μm process

(Redirected from 4 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

edit
  • 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]
