An image sensor includes a semiconductor substrate having first and second opposing surfaces thereon and a photoelectric conversion region of first conductivity type therein, which extends between the first and second surfaces. A two-dimensional array of semiconductor photoelectric conversion devices of second conductivity type is provided within the photoelectric conversion region. A first grid-shaped isolation region is provided, which extends into the photoelectric conversion region from the first surface, and has a first electrically conductive material therein. A second grid-shaped isolation region is provided, which extends into the photoelectric conversion region from the second surface. An electrically conductive contact region is provided, which (i) extends on the second surface and into a portion of the photoelectric conversion region that is outside the two-dimensional array of semiconductor photoelectric conversion devices, and (ii) electrically contacts a portion of the first electrically conductive material within the first grid-shaped isolation region.
