ABSTRACT:
A plurality of edge emitters in a FED array include a plate shaped substrate having parallel, laterally spaced apart grooves formed in a first surface and parallel, laterally spaced apart grooves formed in the opposite surface so that each second groove crosses each first groove at an angle. The combined depths of the grooves is greater than the thickness of the plate substrate so that an opening is formed through the substrate at each point where a second groove crosses a first groove. Gate metal is deposited on the surfaces in the openings and emitter material is deposited on the lands of the first surface to form FED emitters in each opening.
