Patent ID: 7851880

Claim:
A solid-state imaging device comprising: a semiconductor substrate having a foreside and an oppositely facing underside, the foreside being provided with an imaging area and an electrode pad, the imaging area having an array of optical sensors, the electrode pad being disposed around a periphery of the imaging area; a transparent substrate secured to the foreside of the semiconductor substrate with a sealant therebetween; underside wiring that extends through the semiconductor substrate from the electrode pad to the underside of the semiconductor substrate; and a protective film composed of an inorganic insulating material and interposed between the semiconductor substrate and the sealant, the protective film covering at least the electrode pad, thereby preventing the electrode pad from being sandwiched between the sealant and the underside wiring, wherein, the protective film covers the imaging area, the underside wiring, and a connection region of the electrode pad, the connection region being an area where the electrode pad contacts the underside wiring.
