Abstract:
1. A method of fabricating a photoelectric conversion device, comprising the steps of: forming on a substrate a film covering a photoelectric conversion element and a gate electrode of a transistor; forming a first portion on at least a part of a light receiving surface of the photoelectric conversion element, and a side wall on the gate electrode for a lightly doped drain (LDD) structure of the transistor, wherein the first portion and the side wall are formed from the film by etching the film; forming on the substrate a first insulating layer that covers the first portion; forming a copper pattern on the substrate after forming the first insulating layer; forming on the substrate a second insulating layer that covers the first portion and the copper pattern; forming a well-shaped portion by etching the second and first insulating layers, said first portion being positioned between the light receiving surface and the well-shaped portion in a direction vertical to the light receiving surface; forming a second portion by embedding a transparent material in the well-shaped portion, said first portion being positioned between the light receiving surface and the second portion in the direction vertical to the light receiving surface, and said first and second insulating layers being present around the second portion in a direction horizontal to the light receiving surface.
