Semiconductor lithography processes technology
The 14 nm lithography process is a half-node semiconductor manufacturing process used as a stopgap between the 16 nm and 10 nm processes. As is the case with all recent process nodes, while the term "14 nm" is used by a number of companies, the exact feature sizes various wildly from one manufacturer to another. 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.
