Abstract:
1. A semiconductor device comprising: a circuit portion in which a plurality of wiring layers that include circuit elements are laminated; a first light-shielding film that covers an uppermost layer of the wiring layers and light-shields light that is illuminated at the circuit portion; and a plurality of second light-shielding films that are covered by the first light-shielding film and formed so as to respectively encircle the wiring layers in ring forms, wherein outer peripheries of the plurality of second light-shielding films are formed to be successively smaller from an upper layer to a lower layer, so that an outer periphery of each second light-shielding film is at an inner side relative to an outer periphery of a second light-shielding film disposed at an upper layer side thereof; and wherein outer edge portions of the first light-shielding film and the second light-shielding films are curved downward.
