    摘要： A solid-state imaging device includes pixel cells that are formed on a substrate having a first substrate surface side, on which light is irradiated, and a second substrate surface side, on which elements are formed, and separated by an adjacent cell group and an element separation layer for each of the pixel cells or with plural pixel cells as a unit. Each of the pixel cells has a first conductive well formed on the first substrate surface side and a second conductive well formed on the second substrate surface side. The first conductive well receives light from the first substrate surface side and has a photoelectric conversion function and a charge accumulation function for the received light. A transistor that detects accumulated charges in the first conductive well and has a threshold modulation function is formed in the second conductive well.
