Abstract:
1. A solid-state imaging device comprising: a semiconductor substrate; a photoelectric conversion section; a gate oxide film comprising a two-layer film containing a silicon oxide film and a metal oxide thin film; a charge transfer section comprising a charge transfer electrode for transferring an electric charge generated in the photoelectric conversion section, the charge transfer electrode comprising: a first electrode comprising a first conductive film; and a second electrode comprising a second conductive film, the first electrode and the second electrode being disposed on a surface of the semiconductor substrate through the gate oxide film and alternatively arranged; and an interelectrode insulating film which is a sidewall insulating film covering the lateral wall of the first electrode, the interelectrode insulating film separating and insulating the first electrode from the second electrode, wherein the interelectrode insulating film does not extend over the first electrode or over the second electrode.
