Abstract
A solid-state imaging device having a plurality of light-receiving sections which are disposed in a substrate and which generate charge in response to incident light, a planarizing layer which covers predetermined elements disposed on the substrate to perform planarization, a plurality of signal lines disposed above the planarizing layer and a waveguide which guides incident light to each of the light-receiving sections, the waveguide passing through the space between the plurality of signal lines.
Claims6
A solid-state imaging device comprising:
- a substrate;
- a light-receiving section on the substrate, the light-receiving section generates a charge in response to receiving light;
- an insulating film on the substrate:
- a plurality of signal lines located within the insulating film;
- a waveguide in the insulating film and associated with the light-receiving section, the waveguide effective to receive incident light and guide incident light to the light-receiving section;
- and
- a planarizing layer located above the waveguide and the plurality of signal lines;
- wherein,
- the waveguide is tapered from a point of receipt of incident light to the light-receiving section, and
- some of the plurality of signal lines extend over a portion of the light-receiving section.
