1. A method of fabricating a cathode plate for use in a diode display unit comprising the steps of:

  • forming a first layer of conductive material on a face of a substrate;

    patterning and etching the first layer of conductive material to define a plurality of cathode stripes spaced by regions of the substrate;

    forming a second layer of conductive material on the cathode stripes and the regions of the substrate therebetween;

    forming a mask on the second layer of conductive material having a plurality of apertures defining locations for the formation of a plurality of spacers;

    forming said plurality of spacers by introducing a selected material into the apertures;

    selectively removing portions of the second layer of conductive material to expose portions of the cathode stripes; and

    selectively forming a plurality of amorphic diamond emitter regions on selected portions of the cathode stripes.
