    摘要: A semiconductor device includes an interlayer insulating film formed above a semiconductor substrate. The interlayer insulating film has a concave portion. A barrier metal layer is formed along a bottom and a sidewall of the concave portion. The barrier metal layer has a first portion provided along the sidewall of the concave portion and a second portion provided along the bottom of the concave portion. A metal wiring layer is formed in the concave portion via the barrier metal layer. The first portion of the barrier metal layer is composed of a titanium nitride layer whose titanium content is more than 50 at %, and the second portion of the barrier metal layer is composed of a titanium nitride layer whose titanium content is relatively larger than the titanium content of the first portion or of a Ti layer.
