ABSTRACT:
A method of forming an electron emitter for an FED by means of successive evaporative material depositions, providing a flexibility of electron emitter formation which removes geometry constraints that limited the form of prior art field emission device electron emitters. The resultant field emission device yields improved performance as a result of increased insulator layer thickness and electron emitter aspect ratio.
