Abstract:
1. A solid-state imaging device comprising: a signal line formed on a substrate; an island-shaped semiconductor arranged on the signal line; and a pixel selection line connected to a top of the island-shaped semiconductor, wherein the island-shaped semiconductor includes: a first semiconductor layer formed as a bottom portion of the island-shaped semiconductor and connected to the signal line; a second semiconductor layer formed above and adjacent to the first semiconductor layer; a gate connected to the second semiconductor layer through a dielectric film; a charge storage section comprised of a third semiconductor layer connected to the second semiconductor layer and adapted, in response to receiving light, to undergo a change in amount of electric charges therein; and a fourth semiconductor layer formed above and adjacent to the second and third semiconductor layers, and wherein: the pixel selection line is comprised of a transparent conductive film; and a part of the gate is disposed inside a depression formed in a sidewall of the second semiconductor layer.
