US Patent 7750376 Solid-state imaging device and imaging apparatus

A CCD type solid-state imaging device includes: a photoelectric conversion element (n layer 2, p layer 3) formed in a semiconductor substrate 1; a charge transfer channel 5 that transfers electric charges generated in the photoelectric conversion element; a charge read region 6 that reads out the electric charges accumulated in the photoelectric conversion element into the charge transfer channel 5; and a charge read electrode 8 formed above the charge read region 6 with a gate insulating film 10 disposed therebetween. The charge read electrode 8 controls the reading out of the electric charges into the charge transfer channel 5. A gap is formed between the photoelectric conversion element and the charge read electrode 8 in plan view.
