Abstract
A semiconductor device includes an interlayer insulating film INS, adjacent Cu wirings MW formed in the interlayer insulating film INS, and an insulating barrier film BRwhich is in contact with a surface of the interlayer insulating film INSand surfaces of the Cu wirings MW and covers the interlayer insulating film INSand the Cu wirings MW. Between the adjacent Cu wirings MW, the interlayer insulating film INShas a damage layer DMon its surface, and has an electric field relaxation layer ERhaving a higher nitrogen concentration than a nitrogen concentration of the damage layer DMat a position deeper than the damage layer DM
