Patent ID: 8003929

Claim:
A solid-state image pickup device having a plurality of pixels integrated on a light-receiving surface, said device comprising: photodiodes (a) which are disposed in pixel regions serving as the light-receiving surface of a semiconductor substrate and (b) which are partitioned on the pixel basis; signal transferring portions (a) which are disposed on the semiconductor substrate and (b) 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 portions of the insulating films above the photodiodes and whose sides are defined by the portions of the insulating films; and a core layer (a) which is disposed within the concave portions and fills the concave portions and (b) which contains only an inorganic substance that fills the concave portion, and a metal oxide that is ion-implanted into the inorganic substance, the core layer having a heat resistance higher than the heat resistance of a TiO-dispersion organic resin.
