摘要： An electron emitter plate (110) for an FED image display has an extraction (gate) electrode (22) spaced by an insulating spacer (125) from a cathode electrode including a conductive mesh (18). Arrays of microtips (14) are located in mesh spacings (16), within apertures (26) formed in extraction electrode (22) and subcavities (141) formed through apertures (26) in insulating spacer (125). Subcavities (141a) are open to row-adjacent and column-adjacent subcavities (141b, 141c) to form larger main cavities (144). Posts (143) of insulating spacer (125) separate diagonally-adjacent cavities (141d). Subcavities (141) are formed by over-etching a layer of insulating spacer material (25) through apertures (26) before or after forming microtips (14) through the same apertures (26). Over-etching reduces the dielectric constant factor of gate-to-cathode capacitance in the finished structure.

摘要： A size-arrayed emitter structure is disclosed for use in a field emission display device. The emitter structure is designed such that each emitter array (illustratively, an array comprising microtips 40 in a 5.times.5 matrix) has an emitter hole 52 size (critical dimension) distribution that is centered on the optimum hole critical dimension and extends past the point at which the emitter tip 40 will operate. If the manufacturing process varies and produces an actual critical dimension larger than the designed value, emitters with the designed critical dimensions smaller than optimal will shift toward optimal, and emitters with critical dimensions smaller than the minimum operating value will become operational, while emitters with designed critical dimensions larger than optimal will cease to function. Similarly, if the actual critical dimension is smaller than the designed value, emitters with the designed critical dimensions larger than optimal will shift toward optimal, and emitters with critical dimensions larger than the maximum operating value will become operational, while emitters with designed critical dimensions smaller than optimal will cease to function. This will result in a distribution of active emitters in each array that are centered on the optimal value and that extend from the minimum functional emitter critical dimension to the maximum functional emitter critical dimension. Where the number of emitter arrays per display pixel is relatively large, the critical dimension of all of the emitter holes within each array may be designed to be equal, and the totality of arrays within each pixel may be designed such that their emitter hole critical dimensions are centered on the optimum hole critical dimension and extend past the point at which the emitter tips will operate.
