Abstract:
1. A solid-state imaging device comprising: a semiconductor substrate having a signal readout circuit, wherein the signal readout circuit is an MOS transistor circuit, and the signal readout circuit comprises an output transistor; a photoelectric conversion film that generates a signal charge in accordance with an intensity of an incident light; a wiring that leads the signal charge to the semiconductor substrate; a connection portion that connects the wiring to the semiconductor substrate; a charge path that connects the connection portion to a gate portion of the output transistor; and a potential barrier unit provided in the charge path and near the connection portion, wherein the potential barrier unit serves as a potential barrier against a charge of the connection portion so that the signal charge flowing into the connection portion flows into the gate portion of the output transistor while the signal charge is not retained between the potential barrier and the photoelectric conversion film.
