Abstract: An improved high-frequency field-emission microelectronic device (10) has a substrate (20) and an ultra-thin emitter electrode (30) extending parallel to the substrate and having an electron-emitting lateral edge (110) facing an anode (40) across an emitter-to-anode gap (120). A control electrode (70), having a lateral dimension only a minor fraction of the emitter-to-anode gap width, is disposed parallel to the emitter and spaced apart from the emitter by an insulator (60) of predetermined thickness. A vertical dimension of the control electrode is only a minor fraction of the height of the anode. The control electrode may substantially surround a portion of the anode, spaced from the anode in concentric relationship. Inter-electrode capacitance between the emitter and the control electrode has only an extremely small value, consisting of only a very small area term and a very small fringing-field term, thus allowing operation of the microelectronic device at higher frequencies or switching speeds than heretofore. Inter-electrode capacitance between the control electrode and the anode also has only an extremely small value, thus improving higher frequency performance further. Devices having a plurality of control electrodes may also be made with improved inter-electrode capacitance.

Abstract: A an electron source utilizes a novel extraction grid conductor (20,40,41) to assist in focusing an electron beam emitted by the electron source. The extraction grid conductor (20,40,41) has a collimating conductor (29,31) that separate an extraction grid section (17,21,22) of the extraction grid conductor from conducting strips (26,24,32,33) that electrically connect the extraction grid section (17,21,22) to an external voltage source. The collimating conductor (29,31) creates an electric field that prevents emitted electrons from being attracted to the conducting strips (26,24,32,33) thereby maintaining the emitted electron beam in a substantially column-like configuration.
