Patent ID: 7772017

Claim:
A method for producing a solid-state imaging device, the solid-state imaging device containing: a photoelectric conversion section; and a charge transfer section having a charge transfer electrode for transferring an electric charge generated in the photoelectric conversion section, comprising in the following order: sequentially laminating a silicon oxide film and a metal oxide thin film on a semiconductor substrate; forming a first electrode comprising a first conductive film; forming a silicon oxide film on the top of the first electrode; anisotropically etching the silicon oxide film by using the metal oxide thin film as an etching stopper which is not etched by said anisotropic etching, to form a sidewall insulating film on the lateral wall of the first electrode and to remove said silicon oxide film from the top of the first electrode; and forming a second electrode comprising a second conductive film so as to be insulated and separated from the first electrode with intervention of the sidewall insulating film.
