ABSTRACT:
A solid-state imaging device includes an N-type semiconductor substrate, an N-type impurity region provided in the surficial portion of the N-type semiconductor substrate, a photo-electric conversion unit formed in the N-type impurity region, a charge accumulation unit formed in the N-type impurity region so as to contact with the photo-electric conversion unit, and temporarily accumulating charge generated in the photo-electric conversion unit, a charge hold region (barrier unit) formed in the N-type impurity region so as to contact with the charge accumulation unit, and allowing the charge accumulation unit to accumulate the charge, and a charge accumulating electrode provided to the charge accumulation unit. The charge accumulation unit and the charge hold region are formed to be N−-type.
