Abstract:
The present invention relates to a solid-state imaging device. In a pixel array section in the solid-state imaging device, a vertical signal line is provided right under power supply wiring apart from a floating diffusion region in order to reduce load capacitance of the vertical signal line. Furthermore, the power supply wiring is wired to make a cover rate of each vertical signal line with respect to the power supply wiring nearly uniform. As a result, it is possible to suppress variation of load capacitance of the vertical signal line for each pixel. It becomes possible to suppress deviation in a black level, variation of charge transfer, and variation of settling. It becomes possible to obtain an image with higher quality.

Claim (Index 1):
An imaging device comprising:\n a substrate including a plurality of pixels, wherein each pixel of the plurality of pixels includes a photoelectric conversion section; a first wiring layer including a plurality of wirings coupled to the plurality of pixels, wherein the plurality of wirings of the first wiring layer extend in a first direction parallel to a light-incident surface of the substrate; and a second wiring layer including one or more power supply wirings that overlap adjacent wirings of the plurality of wirings of the first wiring layer in a second direction perpendicular to the light-incident surface of the substrate, wherein,\n an area of regions where the one or more power supply wirings overlap the plurality of wirings of the first wiring layer are substantially uniform, and the one or more power supply wirings extend in a third direction parallel to the light-incident surface of the substrate and overlap the plurality of wirings of the first wiring layer at an oblique angle.
