Patent ID: 7075164

Claim:
A semiconductor photoelectric conversion device, comprising: a semiconductor substrate having a principal surface; a number of photoelectric conversion elements formed in the principal surface of said semiconductor substrate; a surface insulating film comprising a silicon oxide film, formed on the principal surface of said semiconductor substrate; functional devices formed on and in the principal surface of said semiconductor substrate adjacent to a number of said photoelectric conversion elements; a light shielding film formed above said semiconductor substrate to contact portions of said surface insulating film, said light shielding film shielding light above said functional devices and having windows for opening an upper space of a predetermined region of each of said photoelectric conversion elements; an effective wavelength shortening member filling a space defined by each of the windows of said light shielding film, occupying a space of low stepped structure formed by the light shielding film, being in direct contact with said surface insulating film, separated from an adjacent window, and being made of transmissive material having a refractive index higher than a refractive index of silicon oxide, in such a manner that an effective wavelength of light passing through the windows is shortened by insertion of the effective wavelength shortening member; and an antireflection film formed between said effective wavelength shortening member and said surface insulating layer, said antireflection film having a refractive index lower than the refractive index of said effective wavelength shortening member and higher than the refractive index of said surface insulating layer.
