Patent ID: 6846695

Claim:
A solid-state imaging device comprising: a vertical charge transfer portion comprising a vertical transfer channel region, and a plurality of vertical transfer electrodes formed on the vertical transfer channel region; and a horizontal charge transfer portion that is connected to at least one end of the vertical charge transfer portion and receives a charge transferred from the vertical charge transfer portion and then transfers the charge, the horizontal charge transfer portion comprising a horizontal transfer channel region, a plurality of first horizontal transfer electrodes formed on the horizontal transfer channel region, and a plurality of second horizontal transfer electrodes arranged between the plurality of first horizontal transfer electrodes; wherein a potential below the first horizontal transfer electrode is higher than a potential below the second horizontal transfer electrode that is arranged adjacent to the first horizontal transfer electrode and backward along a transfer direction with respect to the first horizontal transfer electrode, in a connection portion of the vertical charge transfer portion and the horizontal charge transfer portion, a final vertical transfer electrode arranged at a terminating end of the vertical charge transfer portion and the first horizontal transfer electrode in the horizontal charge transfer portion are arranged so as to have a space therebetween where the second horizontal transfer electrode is arranged, and a distance between the final vertical transfer electrode and the first horizontal transfer electrode in the connection portion is equal to or smaller than a distance between the first horizontal transfer electrodes in the horizontal charge transfer portion.
