摘要： Fabrication of an electron-emitting device entails providing an electron-emitting structure in which multiple sets of electron-emissive elements (24) overlying an emitter electrode (12) are arranged in a line extending generally in a specified direction. Each of a group of control electrodes (28) in the electron-emitting structure contain (a) a main control portion (30) penetrated by a control opening (34) that laterally circumscribes one of the sets of electron-emissive elements and (b) a gate portion (32) that extends across the control opening and has gate openings (36) through which the electron-emissive elements are exposed. Actinic material (38P) is provided over the control electrodes and processed to form a base focusing structure (38) penetrated by multiple focus openings (40) such that each focus opening is centered on a corresponding one of the control openings in the specified direction.

摘要： An electron-emitting device contains an emitter electrode (12), a group of sets of electron-emitting elements (24), a group of control electrodes (28), and a focusing system (37) for focusing electrons emitted by the electron-emissive elements. The sets of electron-emissive elements are arranged generally in a line extending in a specified direction. Each control electrode has a main portion (30) and a gate portion (32). the electron-emissive elements are exposed through gate openings (36) in the gate portion. The main portion of each control electrode crosses over the emitter electrode and has a large control opening (34) which laterally circumscribes one of the sets of electron-emissive elements. The focusing system has a group of focus openings (40) located respectively above the control openings. Each control opening is largely centered on, or/and is no more than 50% as large as, the corresponding focus opening in the specified direction.

摘要： An electron-emitting device utilizes an emitter electrode (12) shaped like a ladder in which a line of emitter openings (18) extend through the electrode. In fabricating the device, the emitter openings can be utilized to self-align certain edges, such as edges (38C) of a focusing system (37), to other edges, such as edges (28C) of control electrodes (28), to obtain desired lateral spacings. The self-alignment is typically achieved with the assistance of a backside photolithographic exposure operation. The ladder shape of the emitter electrode also facilitates the removal of short-circuit defects involving the electrode.

摘要： A flat panel display and a method for forming a flat panel display. In one embodiment, the flat panel display includes a cathodic structure which is formed within an active area on a backplate. The cathodic structure includes a emitter electrode metal composed of strips of aluminum overlain by a layer of cladding material. The use of aluminum and cladding material to form emitter electrode metal gives emitter electrode metal segments which are highly conductive due to the high conductivity of aluminum. By using a suitable cladding material and processing steps, a bond between the aluminum and the cladding material is formed which has good electrical conductivity. In one embodiment, tantalum is used as a cladding material. Tantalum forms a bond with the overlying resistive layer which has good electrical conductivity. Thus, the resulting structure has very high electrical conductivity through the aluminum layer and high conductivity into the resistive layer. Electrode structures that use resistor material, chromium-containing material, nickel and vanadium alloy, and gold are also disclosed.

摘要： An electron-emitting device contains an electron focusing system (37 or 37A) formed with a base focusing structure (38 or 38A), a focus coating (39 or 39A), and an access conductor (106 or 116). The focus coating overlies the base focusing structure and extends into a focus opening (40). The access conductor is electrically coupled to the lower surface of the focus coating. A potential for controlling the focusing of electrons that travel through the focus opening is provided to the focus coating via the access conductor. The focus coating is typically formed by an angled deposition technique.

摘要： Excess emitter material (52B) is removed in multiple steps during the fabrication of an electron-emitting device. A structure is initially provided in which a dielectric layer (44) overlies a non-insulating region (42), control electrodes (80 or 46/80) overlie the dielectric layer, openings (48/50) extend through the control electrodes and dielectric layer, electron-emissive elements (52A) formed with emitter material are situated in the openings, and an excess layer (52B) of the emitter material overlies the control electrodes and the dielectric layer. Portions of the excess emitter material overlying the dielectric layer in the spaces between the control electrodes are initially removed, preferably with etchant that directly attacks the emitter material. Portions (52C) of the excess emitter material overlying the control electrodes above the electron-emissive elements are subsequently removed to expose the electron-emissive elements.

摘要： An electrochemical technique is employed for removing certain material from a partially finished structure without significantly chemically attacking certain other material of the same chemical type as the removed material. The partially finished structure contains a first electrically non-insulating layer (52C) consisting at least partially of first material, typically excess emitter material that accumulates during the deposition of the emitter material to form electron-emissive elements (52A) in an electron emitter, that overlies an electrically insulating layer (44). An electrically non-insulating member, such as an electron-emissive element, consisting at least partially of the first material is situated at least partly in an opening (50) extending through the insulating layer. With the partially finished structure so arranged, at least part of the first material of the first non-insulating layer is electrochemically removed such that the non-insulating member is exposed without significantly attacking the first material of the non-insulating member.

摘要： A flat-panel display including a substrate, a viewing screen, a non-conductive ring, many row conductive electrodes, conductive pads and column buses. The ring vacuum-seals a cavity between the substrate and the viewing screen. Coupled to one surface of the substrate, the row conductive electrodes have a conductivity that is higher than the conductive pads. Each pad is connected to one row electrode, and each pad extends through the ring to allow electrical coupling to its corresponding row electrode from outside the cavity while vacuum is maintained inside the cavity. The row electrodes are substantially parallel to each other, and are substantially perpendicular to the column buses. The conductive electrodes are protected from exposure to the ring. In one embodiment, the ring is a frit seal, the row conductive electrodes are made of aluminum, and the column buses and the pads are made of chromium.
