Abstract
Disclosed is a solid state imaging device, comprising a unit pixel including a photo diode and a MOS transistor for optical signal detection provided with a high-density buried layer for storing optically generated charges generated by light irradiation in the photo diode , a vertical scanning signal driving scanning circuit for outputting a scanning signal to a gate electrode , and a voltage boost scanning circuit for outputting a boosted voltage higher than a power source voltage to a source region . In this case, a boosted voltage is applied from the voltage boost scanning circuit to the source region , and the optically generated charges stored in the high-density buried layer are swept out from the high-density buried layer by a source voltage and a gate voltage risen by the boosted voltage.
