Abstract:
A method for driving a solid-state imaging device, comprising the steps of:providing a solid-state imaging device having a first one-conductive type region, a second one-conductive type region having a one-conductive type impurity concentration lower than that of said first one-conductive type region and provided on said first one-conductive type region in contact with said first one-conductive type region, an opposite-conductive type region in contact with said second one-conductive type region, and a one-conductive type layer forming a p-n junction together with said opposite-conductive type region and constituting a photodiode portion together with said opposite-conductive type region; andapplying a blooming suppressing voltage of a reverse bias between said opposite-conductive type region and said first one-conductive type region so as to form a depletion layer edge within said second one-conductive type region.
