1. A photodetector structure, comprising:

  • a substrate;

    at least one phototransistor, the at least one phototransistor having a base, the base is directly connected to a metal interconnect through which the base is electrically connected to the substrate, but physically separated from the substrate; and

    an n-type conductivity region adjacent to the substrate,wherein the substrate is of p-type conductivity, the at least one phototransistor is formed on the n-type conductivity region, and the metal interconnect is physically separated from the n-type conductivity region.
