Abstract
A semiconductor device includes a semiconductor substrate; an insulating film arranged on the semiconductor substrate; an electrode that contacts a portion of a side surface of the insulating film; a first passivation film that is arranged extending from the electrode to the insulating film, and contacts a surface of the insulating film, and contacts a surface of the electrode; and a second passivation film that is arranged on the first passivation film. A difference between a linear expansion coefficient of the first passivation film and a linear expansion coefficient of the insulating film is smaller than a difference between the linear expansion coefficient of the first passivation film and a linear expansion coefficient of the electrode, and a position where the first passivation film contacts a boundary between the electrode and the insulating film is positioned lower than an upper surface of the insulating film.
