Abstract
A solid-state imaging device includes a transfer element line for transferring an electric charge that is photoelectrically converted in a photoelectric conversion element line formed of a plurality of photoelectric conversion elements, and a charge detector for detecting an electric charge that is transferred by the transfer element line. The charge detector includes output gates disposed adjacently to a final transfer gate of the transfer element line, a reset gate for resetting an electric charge in the charge detector, a floating diffusion formed on a substrate surface adjacently to the output gates and the reset gate, and addition gates formed above the floating diffusion and along the direction from the output gates to the reset gate.

A solid-state imaging device comprising:
- a transfer element line transferring an electric charge photoelectrically converted in a photoelectric conversion element line formed of a plurality of photoelectric conversion elements;
- and
- a charge detector detecting an electric charge transferred by the transfer element line, the charge detector including:
- an output gate connected to a final stage of the transfer element line;
- a floating diffusion converting an electric charge transferred through the output gate into a voltage;
- a reset gate resetting the floating diffusion;
- and
- an addition gate formed above the floating diffusion and along an end from the output gate to the reset gate and supplied with a constant voltage.
