    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 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: An electron-emitting device contains an electron focusing system (37 or 37A) formed with a base focusing structure (38 or 38A) and a focus coating (39 or 39A) that penetrates partway into a focus opening (40) extending through the base focusing structure above an electron-emissive element (24). The focus coating is normally of lower resistivity than the base focusing structure and thereby provides most of the focus control over electrons emitted by the electron-emissive element. The focus coating is typically formed by an angled deposition technique.

    摘要: A gated electron-emitter having a lower non-insulating emitter region (42), an overlying insulating layer (44), and a gate layer (48A, 60A, 60B, 120A, or 180A/184) is fabricated by a process in which particles (46) are distributed over the insulating layer, the gate layer, a primary layer (50A, 62A, or 72) provided over the gate layer, a further layer (74) provided over the primary layer, or a pattern-transfer layer (182). The particles are utilized in defining gate openings (54, 66, 80, 122, or 186/188) through the gate layer. Spacer material is provided along the edges of the gate openings to form spacers (102A, 110A, 124A, 140, or 150B). Dielectric openings (80, 114, 128, 144, or 154) are formed through the insulating layer. The dielectric openings can be created before or after creating the spacers. In either case, emitter material in introduced into either the full dielectric openings, or into the portions of the dielectric openings not covered with spacer material, to form electron-emissive elements (106B, 116B, 130A, 146A, or 156B) typically filamentary in shape.

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: 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.
