Abstract:
1. A solid-state imaging device, comprising: a pixel including a photoelectric conversion section, and a conversion section that converts a signal generated by photoelectric conversion into a pixel signal, wherein an element isolation region has a gate insulation film formed over a substrate directly under a gate electrode, wherein a thickness of the gate insulation film is substantially the same across the substrate, the element isolation region being formed of first and second impurity regions in the substrate, a gate extension of the gate electrode formed directly above the first and second impurity regions, wherein the first impurity region is formed to a depth that is lower than a depth of the second impurity region and the second impurity region is wider than the first impurity region; the element isolation region having no insulation material within the first and second impurity regions are formed, and further comprising the gate electrode of a transistor in the solid-state imaging device extends wider than a channel portion under the gate electrode, and the channel portion has a different doping type than adjacent regions of the gate electrode, wherein the adjacent regions extending over the element isolation region.
