Patent ID: 8692345

Claim:
An image sensing device comprising: a substrate having a plurality of photoelectric conversion portions; a first film disposed over the substrate, the first film covering the photoelectric conversion portions; a light-shielding film disposed between the first film and the substrate, the light-shielding film having apertures for the photoelectric conversion portions, each of the apertures acting as a transit portion through which visible light enters a corresponding photoelectric conversion portion, the light-shielding film having an upper surface and a side wall, the upper surface facing the first film such that the first film is closely adjacent to the upper surface, and the side wall facing the transit portion; and a second film disposed between the first film and the substrate, the second film comprising a first layer having a refractive index different from the first film, the first layer lying within at least the transit portions, and the first layer forming interfaces with the first film, wherein at least one of the upper surface and the side wall comprises a material having maximum spectral reflectance for visible light of 75% or less, and the upper surface comprises a material having minimum spectral reflectance for visible light of ¾ or more of the maximum, and wherein the distance between the interface and the corresponding photoelectric conversion portion is greater than the distance between the photoelectric conversion portion and the lower end of the corresponding transit portion.
