Abstract:
Provided is a semiconductor device that is resistant to the corrosion of titanium nitride forming an anti-reflection film. The semiconductor device includes: a wiring layer which includes a wiring film made of aluminum or an aluminum alloy and formed on a substrate and a titanium nitride film formed on the wiring film; a protection layer which covers a top surface and a side surface of the wiring layer; and a pad portion which penetrates the protection layer and the titanium nitride film, and which exposes the wiring film, the protection layer including a first silicon nitride film, an oxide film, and a second silicon nitride film which are layered in the stated order from the side of the wiring layer.

Claim (Index 3):
A method of manufacturing a semiconductor device, comprising:\n forming a wiring layer by forming, on a substrate, a wiring film and a titanium nitride film in the order stated, and then patterning the wiring film and the titanium nitride film; forming a protection layer so as to cover a top surface and a side surface of the wiring layer, by forming a first silicon nitride film, an oxide film, and a second silicon nitride film in the order stated; and forming a pad portion which penetrates the protection layer and the titanium nitride film, and which exposes the wiring film, by etching the protection layer and the titanium nitride film.
