Patent ID: 8546173

Claim:
A fabrication method of a photoelectric conversion device, the method comprising: forming a first portion on a substrate having a photoelectric conversion element so that the first portion is positioned on at least a part of a light receiving surface of the photoelectric conversion element, the first portion having a thickness equal to or more than a thickness of a gate electrode disposed on the substrate; forming a first insulating layer on the substrate, after the forming of the first portion, so that the first insulating layer covers the first portion and the gate electrode and is present around the first portion in a plane along the light receiving surface, the first insulating layer having a refractive index lower than a refractive index of the first portion; forming a second insulating layer on the first insulating layer; forming a second portion on the first portion, after the forming of the second insulating layer, so that the first portion is positioned between the light receiving surface and the second portion, and the second insulating layer is present around the second portion in a plane along the substrate, the second insulating layer having a refractive index lower than a refractive index of the second portion; forming a first conductive pattern between the forming of the first insulating layer and the forming of the second insulating layer; and forming a second conductive pattern between the forming of the second insulating layer and the forming of the second portion.
