Patent ID: 7638804

Claim:
A solid-state imaging device in which plural unit areas, each having a photoelectric conversion region converting incident light into electric signals are provided adjacently, wherein each photoelectric conversion region is provided being deviated from the central position of each unit area to a boundary position between the plural unit areas, wherein a high refractive index material layer is arranged over the deviated photoelectric conversion region, and a low refractive index material layer is provided over the photoelectric conversion region at the inverse side of the deviated direction, being adjacent to the high refractive index material layer, and wherein optical paths of the incident light are changed by the high refractive index material layer and the low refractive index material layer, and incident light enters the photoelectric conversion region; and wherein the high refractive index material layer and the low refractive index material layer are provided between a passivation film on an insulating layer and a filter layer below an on-chip lens region.
