Abstract
A solid-state imaging device has a progressive-scan structure and includes, in a unit pixel area of a semiconductor substrate, a photoelectric conversion region and a vertical transfer CCD region for reading and transferring a signal charge stored in the photoelectric conversion region by performing four-phase driving using two vertical transfer electrodes each having a two-layer structure formed over the semiconductor substrate with a gate insulation layer disposed therebetween. Among the two vertical transfer electrodes each having a two-layer structure, lead parts of one vertical transfer electrode having the two-layer structure are positioned on the photoelectric conversion region in the unit area.
