Abstract
PURPOSE:To prevent the decrease in the efficiency of a charge transfer device by sufficiently decreasing the length of a channel passage in a narrow part between the partial channel stoppers of low transfer efficiency, thereby alleviating the influence of the potential of the channel stopper. CONSTITUTION:An N type epitaxial layer 2 is superposed on a P type substrate 1, and channel stoppers 8a, 8b are formed across a semiconductor layer 7. Transfer electrodes 9A, 9B forming a series CCD unit 1 and a gate electrode 2 (9C) provided between the series CCD unit 1 and a parallel CCD unit 3 are formed of different conductive layers through an insulating layer 10 on the substrate S, and are superposed via an insulating film, thereby sufficiently shortening the length L of the passage (a) between the channel passage of the series CCD unit 1 and the channel passage under the gate electrode 2. Accordingly, the part affected by the influence of the potential of the channel stopper 8b is shortened to prevent the transfer efficiency decrease, and to reduce the irregularity in the transfer efficiency simultaneously.
