Abstract:
A charge coupled device fabricated on a semiconductor substrate of a first conductivity type, said charge coupled device comprising:isolating regions having a second conductivity type opposite to said first conductivity type, and spaced from each other in a surface portion of said semiconductor substrate; a charge accumulating layer of said first conductivity type formed in said surface portion between said isolating regions; an insulating layer formed on said isolating regions and said charge accumulating layer; transfer electrodes formed on said insulating layer along said charge accumulating layer; and a local impurity region of said second conductivity type formed in said semiconductor substrate, projecting into a central region of said charge accumulating layer for forming a p-n junction, and spaced from said isolating regions such that no portion of said local impurity region contacts said isolating regions.
