Semiconductor lithography processes technology
The 1.5 µm lithography process was the semiconductor process technology used by the major semiconductor companies in the mid 1980s. This process had an effective channel length of roughly 1.5 µm between the source and drain. By the late 80s this process was replaced by 1.3 µm, 1.2 µm, and 1 µm processes.
