Abstract

A semiconductor device according to an exemplary embodiment includes a semiconductor substrate, an interlayer insulating layer, at least one electrode, an inorganic protective layer, and an organic protective layer. The interlayer insulating layer is formed on the semiconductor substrate and has at least one opening. The at least one electrode has part formed on an edge of the at least one opening, and has other part electrically connected, in the at least one opening, to the semiconductor substrate. The inorganic protective layer includes an inner edge portion and an outer edge portion. The inner edge portion covers an edge of the at least one electrode. The inorganic protective layer, except for the inner edge portion, is formed on the interlayer insulating layer. The organic protective layer covers the inorganic protective layer. One of the inner edge portion and the outer edge portion of the inorganic protective layer has an undercut.
