Patent ID: 7842979

Claim:
A solid-state imaging device comprising: a semiconductor substrate; a first impurity region having a first conductivity type provided in a surficial portion of the semiconductor substrate; a photo-electric conversion unit in the first impurity region; a charge accumulation unit in the first impurity region, in contact with the photo-electric conversion unit, and temporarily accumulating charge generated in the photo-electric conversion unit; a charge transfer unit in the first impurity region receiving the temporarily accumulating charge from the charge accumulation unit and transferring the temporarily accumulating charge; a second impurity region in the first impurity region, provided in a surficial portion of an area including the charge accumulation unit and the charge transfer unit, the second impurity region having the first conductivity type; and an electrode provided over the second impurity region, one of a high-level signal and a low-level signal being input to the electrode.
