Abstract
An object of the present invention is to provide a photoelectric conversion device, wherein improvement of charge transfer properties when charge is output from a charge storage region and suppression of dark current generation during charge storage are compatible with each other. This object is achieved by forming a depletion voltage of a charge storage region in the range from zero to one half of a power source voltage (V), forming a gate voltage of a transfer MOS transistor during a charge transfer period in the range from one half of the power source voltage to the power source voltage (V) and forming a gate,voltage of the transfer MOS transistor during a charge storage period in the range from minus one half of the power source voltage to zero (V).
