ABSTRACT:
In a CCD image sensor, a plurality of horizontal CCD registers are disposed adjacent to an image sensing area having matrix-arrayed image sensing cells and a plurality of vertical CCD registers. In the CCD image sensor, the channel impurity concentration of second horizontal CCD register, located away from the image sensing area, is more higher than that of first horizontal CCD register. With this feature, when the charges are transferred to the second horizontal CCD register across the first horizontal register, the residual charges in the first horiozntal CCD register are remarkably reduced.
