ABSTRACT:
In a horizontal transfer section of a solid state imager, a horizontal transfer efficiency can be improved while other element sections are prevented from being substantially affected. In a solid state imager having a horizontal transfer section comprised of a well-region of a second conductivity type formed on the surface of a semiconductor substrate of a first conductivity type and a signal charge transfer region formed on the surface of the well-region of the second conductivity type, the well-region is formed completely in a depletion state by the implantation of impurities into this well-region. The horizontal transfer efficiency is thus improved.
