Patent ID: 8922691

Claim:
A solid-state imaging device comprising: a photodetector on a substrate, the photodetector configured to generate a signal charge by converting incident light into the signal charge; a floating diffusion region configured to receive the signal charge generated by the photodetector; a plurality of metal oxide semiconductor transistors including a transfer transistor that transfers the signal charge to the floating diffusion region and an amplification transistor that outputs a pixel signal corresponding to a potential of the floating diffusion region; a multi-wiring layer in a layer carried on the substrate, the multi-wiring layer composed of a plurality of wiring layers electrically connected to the metal oxide semiconductor transistors via contact portions; and a light-shielding film constituted by a bottom wiring layer that is disposed between the substrate and the multi-wiring layer, the light-shielding film (a) being over the floating diffusion region to shield the floating diffusion region from the light such that the light-shielding film extends from a region over the floating diffusion region to a region surrounding the photodetector except for a region directly above an aperture of the photodetector, (b) electrically connected to the floating diffusion region via a first contact portion, and (c) electrically connected to a gate electrode of the amplification transistor via a second contact portion, wherein, each of the MOS transistors are electrically connected to the wiring layers in the multi-wiring layer by contact portions via an intermediate film constituted by the bottom wiring layer.
