14 nm lithography process

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.

Intel[edit]

14 nm became Intel's 2nd generation FinFET transistors. Intel uses TiN pMOS / TiAlN nMOS as work function metals. Intel makes use of Self-Aligned Double Patterning (SADP) with 193 nm immersion lithography at critical patterning layers. Compared to all other "14 nm nodes", Intel's process is the densest and considerably so, with >1.5x raw logic density.

Intel improved on their original process with the "14nm+" offering 12% higher drive current. They later improved on that with the "14nm++" process which allows for +23-24% higher drive current for 52% less power. The 14nm++ process also appear to have slightly relaxed the CPP from 70 to 84 nm.

Samsung[edit]

This process became Samsungs' and GlobalFoundries first generation of FinFET-based transistors. Samsung uses TiN pMOS / TiAIC nMOS as work function metals.
