The 150 nm lithography process is a half-node semiconductor manufacturing process used as a stopgap between the 180 nm and 130 nm processes. Commercial integrated circuit manufacturing using 55 nm process began in early 2000s. This technology superseded by commercial 130 nm, 110 nm, and 90 nm processes.
