Patent ID: 7034333

Claim:
A semiconductor sensor, comprising: a semiconductor layer having a top surface; a plurality of pixel surface coatings positioned above the top surface of the semiconductor layer to form a corresponding plurality of pixels, wherein each pixel surface coating is separated from each adjacent pixel surface coating, wherein the plurality of pixel surface coatings are conductive, wherein electrons incident one of the plurality of pixel surface coatings are absorbed by the one of the plurality of pixel surface coatings resulting in a charge associated with the pixel corresponding to the one of the plurality of pixel surface coatings such that the charge produces a readable voltage associated with the pixel corresponding to the one of the plurality of pixel surface coatings; and a conductive layer positioned above the top surface of the semiconductor layer and positioned so that electrons passing between adjacent pixel surface coatings are incident on the conductive layer and prevented from penetrating into the semiconductor layer, wherein the conductive layer is insulated from the plurality of pixel surface coatings.
