Patent ID: 7985947

Claim:
A method of designing antireflective films for a photoelectric conversion apparatus that includes: a plurality of light receiving portions, an antireflective film arranged on each of the plurality of light receiving portions, and color filter layers of a plurality of colors arranged on each of the antireflective films, the method comprising steps of: determining a thickness range of antireflective films such that, within a range of wavelengths that includes wavelengths corresponding to a plurality of colors of color filter layers of a photoelectric conversion apparatus, a transmittance of a relatively thin antireflective film is always less than a transmittance of a relatively thick antireflective film, or the transmittance of the relatively thin antireflective film is always greater than the transmittance of the relatively thick antireflective film; and designing an antireflective film to be used in a photoelectric conversion apparatus based on the thickness range determined in the determining step.
