ABSTRACT:
A solid-state image pickup device includes a plurality of pixels on a light-receiving surface, photodiodes disposed on the light-receiving surface of a semiconductor substrate while being partitioned on the pixel basis, signal transferring portions which are disposed on the semiconductor substrate and which read signal charges generated and stored in the photodiodes or voltages corresponding to the signal charges, insulating films disposed on the semiconductor substrate while covering the photodiodes, concave portions disposed in the insulating films, pad electrodes disposed on the insulating films, a passivation film which covers inner walls of the concave portions, which is disposed on the pad electrodes, and which has a refractive index higher than that of silicon oxide, and a core layer which is disposed on the passivation film while being filled in the concave portions and which has a refractive index higher than that of silicon oxide.
