Patent ID: 8593538

Claim:
A solid state imaging device, comprising: a semiconductor substrate; first, second, and third photoelectric conversion portions provided in a surface region of the semiconductor substrate; a blue color filter provided at a position corresponding to the first photoelectric conversion portion, the blue color filter having a first film thickness to give a first light path length; a green color filter provided at a position corresponding to the second photoelectric conversion portion, the green color filter having a second film thickness to give a second light path length longer than the first light path length; a red color filter provided at a position corresponding to the third photoelectric conversion portion, the red color filter having a third film thickness to give a third light path length longer than the second light path length; a flattening film formed on the blue color filter, the green color filter, and the red color filter, the flattening film flattening steps of the color filters; and micro lenses provided on the flattening film, each of the micro lenses being formed at a position corresponding to each of the first, the second, and the third photoelectric conversion portions, wherein each of the film thicknesses d of the color filters is set approximately to satisfy d=(λ×m)/(2×n) or more, where λ is a central wavelength of each color band of the color filters, m is an integer of three or more, and n is each refractive index of the color filters.
