800 nm process

The 800 nm process (800 nanometer process) is a level of semiconductor process technology that was reached in the 1987–1990 timeframe, by companies, such as Intel, ATI Technologies, and IBM.

The 800 nm 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 800 nanometers wide.
