ABSTRACT:
A method is provided for creating gated filament structures for a field emission display. A multi-layer structure is provided that includes a substrate, an insulating layer, a metal gate layer positioned on a top surface of the insulating layer and a gate encapsulation layer positioned on a top surface of the metal gate layer. A plurality of gates are provided and define a plurality of apertures on the top of the insulating layer. A plurality of spacers are formed in the apertures at their edges on the top surface of the insulating layer. The spacers are used as masks for etching the insulating layer and form a plurality of pores in the insulating layer. The pores are plated with a filament material to create a plurality of filaments. The pores can be overplated to create the plurality of filaments. The filaments are vertically self-aligned in the pores.
