Patent ID: 8223234

Claim:
A solid-state imaging device, comprising: a substrate; and a plurality of pixel portions arranged over the substrate, wherein: each of the pixel portions includes a photoelectric conversion portion provided over the substrate and a color filter provided over the photoelectric conversion portion; the solid-state imaging device includes partitions for preventing light that is incident on the color filter of each pixel portion from entering adjacent pixel portions; the partitions are provided between the color filters of the adjoining pixel portions so as to cover side surfaces of the color filters; each of the photoelectric conversion portions includes a lower electrode provided over the substrate, an upper electrode provided over the lower electrode, and a photoelectric conversion layer provided between the lower electrode and the upper electrode; each of the pixel portions further includes a protective layer provided between the color filter and the upper electrode, for protecting the photoelectric conversion portion; and the protective layer has a thickness of greater than 0 μm and smaller than or equal to 1.0 μm; and wherein a width of each of the partitions in a direction that is parallel with surfaces of the color filters is in a range of from 0.05 μm to 0.2 times a size of each of the pixel portions; and a sum of a thickness of the color filters and the thickness of the protective layer is greater than 0.2 μm and smaller than or equal to 1.4 μm.
