Patent ID: 8829635

Claim:
An electronic apparatus comprising: an optical system arranged such that light is concentrated toward an imaging surface of a solid-state imaging device, the solid state imaging device comprising: a semiconductor layer including a photoelectric conversion element formed in a pixel region and a semiconductor element formed in a surface side opposite to a surface through which light enters; a wiring layer provided over a surface of the semiconductor layer so as to cover the semiconductor element; a support substrate provided over the wiring layer at an opposite side of the semiconductor layer; a bonding layer provided between the wiring layer and the support substrate, wherein the wiring layer includes a pad electrode and an opening formed so that a surface of the pad electrode is exposed; and first and second convex sections provided in a region where the pad electrode is formed, the first convex section provided at a surface of the wiring layer which opposes the support substrate and the second convex section provided at a surface of the support substrate which opposes the wiring layer, wherein the first and second convex sections are formed between a portion of the pad electrode and the support substrate.
