Abstract

A semiconductor device includes a semiconductor substrate, an interlayer dielectric film, a plurality of pad parts, a wiring layer, and a surface protection film. The semiconductor substrate includes a semiconductor element on a surface of the semiconductor substrate. The interlayer dielectric film is disposed on the surface of the semiconductor substrate. The wiring layer is disposed in the interlayer dielectric film. The hard film is disposed opposite to the semiconductor substrate with respect to the interlayer dielectric film, and is harder than the interlayer dielectric film. The pad parts are disposed opposite to the interlayer dielectric film with respect to the hard film. The surface protection film is disposed in at least an opposing region where the pad parts oppose to each other. The surface protection film is a silicon nitride film or a silicon oxide film.
