摘要： 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.

摘要： A charge-transfer device contains a high-resistance p-well layer formed in the surface of an n-type semiconductor substrate. In the surface of the well layer, a charge-transfer n-channel layer, a charge storage n-channel layer, a charge release n-channel layer, and a charge release n-type drain are formed continuously. An output gate electrode is provided above the junction of the transfer channel layer and the storage channel layer, with an insulating film interposed therebetween. Provided above the release channel layer is a reset gate electrode with an insulating film interposed therebetween. In the surface of the storage channel layer, a charge-sensing p-channel layer of a charge-sensing transistor is formed. The charge-sensing channel layer is arranged so as to be in contact with neither the transfer channel layer nor the release channel layer. The storage channel layer is arranged so as to contain a first surface portion which adjoins the transfer channel layer and is in contact with a covering insulating film, and a second surface portion which adjoins the release channel layer and is in contact with the covering insulating film. In the surface of the substrate, a p-type source and drain layers of the charge-sensing transistor are formed so as to face each other with the sensing channel interposed therebetween. The potential of the storage channel layer without charges is set higher than that of the release drain layer.
