Claim 5:
6. An image sensor comprising:
a substrate, the substrate comprising a conductive substrate;
a first electrode spaced apart from and above the substrate;
a plurality of photodetection layers between the first electrode and the substrate and configured to convert incident light into an electrical signal, the plurality of photodetection layers including a semiconductor material;
an interlayer between and separating a pair of photodetection layers of the plurality of photodetection layers and including a metallic or semi-metallic material continuously along a width of the interlayer and having anisotropy in electrical conductivity such that the interlayer has lower electrical conductivity parallel to a thickness of the interlayer; and
an insulating layer between the substrate and a photodetection layer of the plurality of photodetection layers above the substrate, the insulation layer including an opening and a lower one of the pair of photodetection layers of the plurality of photodetection layers extends through the opening to contact the substrate.
