ABSTRACT:
A serial-parallel-serial, charged-coupled device includes an array of horizontal rows and columns of closely spaced charge storage cells. Each storage cell is formed by an electrode covering an insulation layer above a semiconductor substrate. The semiconductor substrate of each storage cell includes a channel region for conducting carriers laterally through the storage cell. The channel region of each storage cell included both in a first row of the array and in any column of the array has a tilted potential gradient providing an electric field facilitating charge carrier drift within the channel region in two lateral directions, toward a neighboring storage cell of the first row and also toward a neighboring storage cell of its column.
