ABSTRACT:
Photoelectric converters are arranged two-dimensionally in a semiconductor substrate. A planarizing layer, a light shielding film, a further planarizing layer and condenser lenses are formed sequentially on the semiconductor substrate and the photoelectric converters. The light shielding film has apertures at positions corresponding to the photoelectric conversion devices. Multilayer interference filters that transmit either a red, green or blue wavelength component of light are disposed in the apertures.
