Abstract:
1. A CCD type solid-state imaging device comprising: a photoelectric conversion element formed in a semiconductor substrate; a charge transfer channel that transfers electric charges generated in the photoelectric conversion element; a charge read region that reads out the electric charges into the charge transfer channel; a charge read electrode formed above the charge read region with a gate insulating film disposed therebetween, the charge read electrode that controls the reading out of the electric charges into the charge transfer channel; and a light shielding layer, wherein: a gap is formed between the photoelectric conversion element and the charge read electrode in plan view, the gate insulating film is provided between the light shielding layer and the charge read region so that the gate insulating film is in direct contact with the light shielding layer and the charge read region, and the light shielding layer is formed on the charge read region in a portion which is unoccupied by the charge read electrode along the gate insulating film.
