Abstract:
A semiconductor device includes a substrate; a laminate which is formed on one main surface side of the substrate, and includes an aluminum alloy wiring and an insulating film surrounding the aluminum alloy wiring; and a silicon nitride film covering the laminate, in which the silicon nitride film and the insulating film have an opening portion, through which the silicon nitride film and the insulating film, formed at a position overlapped with a bonding portion of the aluminum alloy wiring, and a deposition made of a residue caused by reverse sputtering, which contains silicon and nitrogen, adheres to a portion exposed from the opening portion of a surface of the aluminum alloy wiring, to form a film.

Claim (Index 8):
A semiconductor device according to  claim 2 , wherein a titanium nitride film is formed in a periphery of a portion exposed from the opening portion of a surface of the aluminum alloy wiring.
