Patent ID: 7442973

Claim:
A solid state imaging device comprising: 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, wherein, the waveguide comprises a light-transmissive film having a relatively high refractive index, the light-transmissive film is embedded in a hole formed by etching an insulating film having a relatively low refractive index, the light-transmissive film includes a first material portion containing at least hydrogen, the light receiving section contains hydrogen released from the first material portion by heat treatment in a hydrogen atmosphere, and the first material portion has an opening at the top, and a second material portion having a refractive index lower than that of the first material portion is disposed in the opening.
