Abstract
A field emission device () is provided that prevents electrical breakdown. The field emission device () comprises an anode () distally disposed from a cathode plate that includes an insulating substrate () having a portion exposed to the anode (), and a cathode metal () overlying another portion of the insulating substrate (). A gate electrode () overlies an oxide () above at least a portion of the cathode metal () and optionally above a portion of the substrate. A dielectric layer () is positioned between a resistive layer () and the cathode metal (), and substantially all of the exposed substrate, and underlies substantially all of the gate electrode () including its edges (), providing a resistance between the cathode metal () and the edges ().
