Abstract: According to one aspect of the invention, a field emission display is provided comprising: an anode; a phosphor screen located on the anode; a cathode; an evacuated space between the anode and the cathode; an emitter located on the cathode opposite the phosphor; wherein the emitter comprises an electropositive element both in a body of the emitter and on a surface of the emitter. According to another aspect of the invention a process for manufacturing an FED is provided comprising the steps of: forming an emitter comprising an electropositive element in the body of the tip; positioning the emitter in opposing relation to a phosphor display screen; creating an evacuated space between the emitter tip and the phosphor display screen; and causing the electropositive element to migrate to the an emission surface of the emitter.

Abstract: A field emission display includes a substrate, a plurality of emitters formed on the substrate, a semiconductor device formed in or on the substrate for controlling the flow of electrons to the emitters and a dielectric layer formed on the substrate. An extraction grid is formed on the dielectric layer substantially in a plane of tips of the plurality of emitters and includes openings each surrounding one of the emitters. The display also includes a transparent viewing screen, a transparent conductor formed on the viewing screen and a cathodoluminescent layer formed on the transparent conductor. The semiconductor device includes a gate dielectric and a field oxide. Significantly, the field oxide includes an interfacial region acting as a trapping and recombination site for mobile charge carriers. As a result, the semiconductor device is more robust and is better able to resist parameter shifts or performance degradation due to exposure to X-rays and photons that are incidentally generated along with the desired images on the display. This results in a more robust field emission display.
