Method to form self-aligned gate structures and focus rings










Image Number 5 for United States Patent #5653619.

A selective etching and chemical mechanical planarization process is employed for the formation of self-aligned gate and focus ring structures surrounding an electron emission tip for use in field emission displays. The process is employed to construct an emission grid whereby the gate structure is capable of producing a field strength at the cathode tip sufficient to generate electron emission. The gate is disposed at a location above the tip such that the gate physically intercepts the outermost lateral portions of the beam, yet does not induce a significant electrostatic outward divergence of the beam, thereby reducing the cross-section of the beam.
