Abstract:
1. A semiconductor device comprising: a first interlayer insulating film formed over a main surface of a semiconductor substrate; first wirings buried in the insides of first wiring grooves formed in the first interlayer insulating film; a first barrier insulating film covering the first wirings; a second interlayer insulating film formed over the first interlayer insulating film; a fuse buried in the inside of a second wiring groove formed in the second interlayer insulating film; a second wiring buried in the inside of a third wiring groove formed in the second interlayer insulating film; a second barrier insulating film covering the fuse and the second wiring; an uppermost layer wiring formed over the second barrier insulating film through a first insulating film; a surface protective film covering the uppermost layer wiring; a first polyimide film formed over the surface protective film; a leader line formed over the first polyimide resin film and electrically connected to the uppermost layer wiring; a second polyimide resin film for covering the leader line; and an external connection terminal formed over the leader line and exposed from part of the second polyimide resin film, wherein the second barrier insulating film is thicker than the first barrier insulating film, wherein a first opening reaching the surface of the second barrier insulating film is formed in the first insulating film and the surface protective film above the fuse, and wherein a second opening reaching the uppermost layer wiring is formed in the surface protective film above the uppermost layer wiring.
