ABSTRACT:
A solid-state imaging device of the present invention includes a vertical charge transfer portion and a horizontal charge transfer portion that is connected to at least one end of the vertical charge transfer portion. The vertical charge transfer portion includes a vertical transfer channel region and a plurality of vertical transfer electrodes formed on the vertical transfer channel region. The horizontal charge transfer portion includes 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. 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 the solid-state imaging device of the present invention, in a connection portion of the vertical charge transfer portion and the horizontal charge transfer portion, a distance between 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 is equal to or smaller than a distance between the first horizontal transfer electrodes in the horizontal charge transfer portion.
