Patent ID: 7795654

Claim:
A solid-state imaging device comprising: a semiconductor substrate; a photoelectric conversion section; a charge transfer section comprising a charge transfer electrode transferring an electric charge generated in the photoelectric conversion section, the charge transfer electrode comprising: a first electrode comprising a first conductive film; and an adjacent second electrode comprising a second conductive film; a gate oxide film at least below the first electrode consists of a silicon oxide film, the silicon oxide film is in direct contact with both of the first electrode and the semiconductor substrate, the first electrode and the adjacent second electrode being disposed on the gate oxide film and alternatively arranged; and a interelectrode insulating film comprising a sidewall insulating film covering a lateral wall of the first electrode, the interelectrode insulating film separating and insulating the first electrode from the adjacent second electrode, the sidewall insulating film comprises: a first insulating film including a lateral wall portion covering and directly contacting the lateral wall of the first electrode and an L-shaped portion forming a substantially right angled region between the lateral wall portion and the L-shaped portion covering and directly contacting with the top of the gate oxide film between the first electrode and the adjacent second electrode; and a second insulating film different from the first insulating film, provided on the first insulating film in the substantially right angled region between lateral sides of the first and the adjacent second electrodes and the second insulating film directly contacting the adjacent second electrode.
