ABSTRACT:
A field emission cathode and a method of manufacturing a field emission cathode, wherein a primitive tip is formed under a first thermal oxide layer, and a nitride layer is formed on the surface of the first thermal oxide layer covering the primitive tip so that only the lower portion of the tip is oxidized without the upper portion of the tip being oxidized by a second thermal oxidation process. The method can attain a constant and controllable tip height.
