Patent ID: 7522204

Claim:
A solid-state imaging device comprising: a semiconductor substrate of a first conductivity type; a photodiode provided in the semiconductor substrate; a diffusion layer of a second conductivity type provided in the semiconductor substrate, the diffusion layer being spaced away from the photodiode; a gate wiring layer provided on the semiconductor substrate between the photodiode and the diffusion layer; a gate insulating film interposed between the semiconductor substrate and the gate wiring layer; a first wiring layer provided on the semiconductor substrate at a position which faces the gate wiring layer across the photodiode in a first direction, the first wiring layer being adjacent to the photodiode; an interlayer insulating film provided over the semiconductor substrate, the gate wiring layer, and the first wiring layer; a microlens provided on the interlayer insulating film at a position which faces the photodiode across the interlayer insulating film; and a second wiring layer electrically connected to the diffusion layer, the second wiring layer provided over the semiconductor substrate and the gate wiring layer, wherein a distance from an optical axis of the microlens to a side surface of the gate wiring layer is smaller than a distance from the optical axis of the microlens to a side surface of the second wiring layer in a second direction perpendicular to the first direction.
