Patent ID: 8890055

Claim:
A method of producing a solid-state imaging device comprising the steps of: forming on a substrate a photoelectric conversion portion that receives light on a light-receiving surface and that photoelectrically converts the light received on the light-receiving surface to generate a signal charge; forming above the light-receiving surface an optical waveguide that guides light to the light-receiving surface and absorbs exposure light from an exposure process during subsequent formation of a color filter; and forming, above the optical waveguide, the color filter from which colored light of selected wavelengths is emitted to the optical waveguide, wherein, in the step of forming the color filter above the optical waveguide, the color filter is formed from a photosensitive resin film containing a first dye by performing the exposure process on the photosensitive resin film and then performing a development process on the photosensitive resin film, in the step of forming the optical waveguide, a core portion of the optical waveguide is formed so that the core portion contains a second dye that absorbs exposure light radiated onto the photosensitive resin film through the color filter when the exposure process is performed in the step of forming the color filter above the optical waveguide, wherein the absorption of the exposure light reduces reflection of the exposure light to the color filter to increase a pattern accuracy of the color filter, and the exposure process is performed after the optical waveguide is formed such that the exposure process uses the optical waveguide to absorb exposure light radiated from the exposure process, wherein the second dye in the core portion absorbs an amount of the exposure light comprising an i-line wavelength light that is greater than an amount of center wavelength light.
