Abstract : A field-emitter-array device includes a substrate supporting thin-film layers of conductive material and intervening thin-film layers of insulative material. The lateral edges of the thin-film layers form a field emitter array including a field-emitter edge electrode interposed between a pair of control electrodes. The control electrode edges produce a symmetric field causing the flow of field emitted electrons to be substantially parallel to the plane of the control and field-emitter edge electrodes. The direction of electron flow can be further controlled by additional electrodes in the form of additional thin-film conductive layers or external electrodes. A process for making the emitter device includes forming on a support member a plurality of planar first and second thin-film layers of insulative material alternately disposed between first, second and third thin-film layers of conductive material, forming a channel through the thickness of the layers and oriented perpendicular thereto, exposing the lateral edges of the layers of conductive and insulative materials adjacent to the channel to form a field emitter edge electrode interposed between a pair of control electrodes. Additional electrodes may be provided to form and deflect the electron flow.
