Patent ID: 8390134

Claim:
A semiconductor device, wherein a semiconductor substrate has a wire formation region and a guard ring formation region, wherein there are formed in the wire formation region: (a1) a first pad formed in an upper layer of the semiconductor substrate; (b1) a first surface protective film in which a first opening is formed over the first pad; and (c1) a second surface protective film in which a second opening is formed over the first pad and which is formed over the first pad and the first surface protective film, wherein the first pad has: (a11) a first conductive film; and (a12) an antireflection film formed over the first conductive film, wherein the second opening is included in an inner region of the first opening, wherein the antireflection film is removed in the inner region of the first opening, wherein there are formed in the guard ring formation region: (a2) a second pad formed in an upper layer of the semiconductor substrate; (b2) the first surface protective film in which a third opening is formed over the second pad; and (c2) the second surface protective film in which the third opening is embedded and which is formed over the second pad and the first surface protective film, wherein the second pad has: (a21) the first conductive film; and (a22) the antireflection film formed over the first conductive film, and wherein the antireflection film is removed in an inner region of the third opening.
