Abstract

A semiconductor device having a TiN film serving as a barrier layer and a TiN.sub.x (0.3<X<0.9) film between a wiring layer and a semiconductor substrate is disclosed. Interposition of the TiN.sub.x film between the semiconductor substrate and the TiN film lowers the contact resistance in the contact region between the semiconductor substrate and the wiring layer and also the leakage current and improves the adhesion between the wiring layer and the semiconductor substrate, so that the characteristics and reliability of the semiconductor device are greatly improved.
