1. An image sensor having a plurality of pixels arranged in a series of row and columns comprising:

  • a semiconductor material of a first conductivity type;

    at least two adjacent pixels formed within the semiconductor material, each of the pixels having a charge to voltage conversion region operatively coupled to a photodetector such that the charge to voltage conversion regions are spatially isolated from each other; and

    an interconnect layer that permanently shorts together the charge to voltage conversion regions.
