Titanium nitride is the most commonly encountered barrier material. It was introduced by Nicolet in the 1970''s. Titanium nitride is a hard, dense, refractory material with unusually high electrical conductivity. TiN is very hard and has a very high melting point, and it is a poor thermal expansion match to silicon; thus stress is often an issue ...
