Abstract:
A method for fabricating a baseplate in the manufacturing of a field emission display, comprising:covering an emitter substrate having a plurality of emitters projecting from the emitter substrate to an emitter tip elevation with an insulating material to form an insulator layer, the insulator layer generally conforming to the emitter substrate and the emitters;depositing a single, metal interconnect/grid layer over the insulator layer to generally conform to the insulator layer and the emitters;planarizing the interconnect/grid layer with a chemical-mechanical planarization method to an endpoint at which holes are formed in the interconnect/grid layer over the emitters at an elevation above the emitter tip elevation; andselectively removing portions of the insulator layer in the holes of the interconnect/grid layer and adjacent to the emitters to form cavities that expose the emitters.
