6 μm process

The 6 μm process (6 micrometers) is the level of semiconductor process technology that was reached around 1974 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.
