The 14 nanometer (14 nm) lithography process is a half-node semiconductor manufacturing process used as a stopgap between the 16 nm and 10 nm processes. The term "14 nm" is simply a commercial name for a generation of a certain size and its technology, as opposed to gate length or half pitch. Commercial integrated circuit manufacturing using 14 nm process began in 2014. This technology is set to be replaced with 10 nm process in 2017.

Industry

14 nm became Intel's 2nd generation finFET transistors. This process became Samsungs' and GlobalFoundries first generation of finFet-based transistors. Intel uses TiN pMOS / TiAlN nMOS while Samsung uses TiN pMOS / TiAIC nMOS as work function metals. Intel makes use of Self-Aligned Double Patterning (SADP) with 193 nm immersion lithography at critical patterning layers.
