Semiconductor lithography processes technology
The 14 nanometer (14 nm) lithography process is a semiconductor manufacturing process node serving as shrink from the 22 nm process. 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. The 14 nm node was introduced in 2014/2015 and is currently getting replaced by the 10 nm process.

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.
