Abstract
A method of producing an FED including a central conductive region having a surface perpendicular to the supporting structure forming a device anode, a structure including first and second layers of intrinsic semiconductor material with a conductive layer, forming an emitter, sandwiched therebetween and stacked to each provide a surface parallel to and spaced from the conductive region surface, and conductive layers disposed on the provided surfaces of the first and second layers, perpendicular to the sandwiched conductive layer, in spaced relation to each other and the sandwiched conductive layer to form gate extraction electrodes.
