ABSTRACT:
A CCD image sensor having an N type photodetecting region, an N type VCCD region and an N type HCCD region, comprising a P type layer formed underneath and surrounding said N type VCCD region, an N type layer formed underneath and surrounding said P type layer, a P type well formed underneath and surrounding said N type layer, and an N type substrate formed under said P type well, said substrate being adapted and arranged for the application thereto of a shutter voltage. In accordance with the present invention, the CCD image sensor is capable of preventing an overflow drain caused by error charges or excess charges resulting from a smear. Therefore, the photoelectric efficiency can be increased in a wavelength of the red color type wherein the amount of light energy is small.
