Abstract
A method of producing a solid-state imaging device includes the steps of forming on a substrate a photoelectric conversion portion that receives light on a light-receiving surface and that photoelectrically converts the received light to generate a signal charge, forming above the light-receiving surface an optical waveguide that guides light to the light-receiving surface, and forming above the optical waveguide a color filter which colors light and from which colored light is emitted to the optical waveguide, wherein, in forming the color filter, the color filter is formed from a photosensitive resin film containing a dye by performing an exposure process and then performing a development process on the film, and in forming the optical waveguide, a core portion of the optical waveguide is formed so that the core portion absorbs exposure light radiated onto the photosensitive resin film when the exposure process is performed.
