Abstract
Official abstract text for this publication.
A photoelectric conversion device comprises a high-refractive-index portion at a position close to a photoelectric conversion element therein. And, the high-refractive-index portion has first and second horizontal cross-section surfaces. The first cross-section surface is at a position closer to the photoelectric conversion element rather than the second cross-section surface, and is larger than an area of the second cross-section surface, so as to guide an incident light into the photoelectric conversion element without reflection.
First claim
Opening claim text (preview).
The invention claimed is: 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 ar…
