    摘要: The semiconductor device having both vertically arranged CCDs and a horizontal CCD, such as, in connection with a solid state image pickup device, is provided with a horizontal CCD in which the transfer speed and the transfer efficiency of a horizontal CCD thereof is improved substantially. In such a device, a plurality of photodiodes are provided on a semiconductor substrate, vertical CCDs are provided on the semiconductor substrate for transferring signal charges of the photodiodes and a horizontal CCD is provided on the semiconductor substrate for transferring signal charges received from the vertical CCDs. The vertical and horizontal CCDs of such a semiconductor device are formed in a well structure provided on the substrate such that the depletion region extending from the channel of the horizontal CCD and a depletion region produced between the underlying substrate and the well are configured to meet each other under each of the transfer electrodes of the horizontal CCD. The depletion region extending from a channel of the vertical CCDs and the depletion region produced between the underlying substrate and the well, however, do not meet each other under each of the transfer electrodes thereof.
