{{Semiconductor manufacturing processes}}

The 1.5 μm process (1.5 micrometer process) is the level of MOSFET semiconductor process technology that was reached around 1981{{ndash}}1982, by companies such as Intel and IBM.

The 1.5 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 1.5 micrometers wide.
