Abstract: A field emission array includes a plurality of pixels. Each pixel includes at least one resistor, at least one emitter tip overlying each resistor, and at least one substantially vertically oriented conductive line positioned laterally adjacent each resistor. The pixels may be arranged in substantially parallel lines. Adjacent pixels are separated and electrically isolated from one another by recessed areas located therebetween. Each conductive line is located within a recessed area. The conductive lines of a field emission array that includes lines of pixels may contact the resistors of each pixel of the corresponding line of pixels. Base portions of at least some of the emitter tips of the field emission array may overlie a portion of the conductive line that corresponds to the pixel of which such emitter tips are a part. Field emission displays that include such field emission arrays are also disclosed.

Abstract: A system and method for fabricating a FED device is disclosed. The system and method provide for use of PECVD hydrogenation followed by nitrogen plasma treatment of the tip of the current emitter of the FED device. The use of this process greatly reduces the native oxides in the tip of the current emitter. Such native oxides function as undesirable insulators degrading current emission. By reducing the amount of oxides in the tip, this invention provides for an increase in the current emission of the FED device.

Abstract: A method for fabricating a field emission structure is disclosed. A first dielectric layer and a second material layer are disposed over a substrate and at least one emitter tip thereon. Planarization of the second layer exposes regions of the first layer that cover the emitter tip, which regions may then be removed through the second layer. Substantially Substantial removal of the second layer reduces any conductive defects that protrude from a surface of the first layer. A third, dielectric layer and fourth, grid layer are then formed. Planarization of the fourth layer forms grid openings and exposes dielectric material of the third layer which overlies the emitter tip. Dielectric material of one or both underlying layers may then be removed to expose the outer surfaces of the emitter tip.
