Abstract:
1. A method for producing a solid-state imaging device, which comprises: a photoelectric conversion section; a charge transfer section having a charge transfer electrode for transferring an electric charge generated in the photoelectric conversion section; and an antireflection film covering a light-receiving region in the photoelectric conversion section, wherein forming the antireflection film comprises: forming a sidewall on a lateral wall of the charge transfer electrode after forming the charge transfer electrode; forming an antireflection film on a substrate surface where the sidewall is formed; forming a resist on the antireflection film; melting and flattening the resist to expose the antireflection film on the charge transfer electrode; removing the antireflection film by using the resist as the mask; removing the sidewall; covering the charge transfer electrode with an insulating film; and forming a light-shielding film that reaches a level lower than the top surface of the antireflection film, and that surrounds the periphery of the antireflection film.
