ABSTRACT:
A cold cathode field emission device having a cone shaped emitter (112, 208) formed with a substantially normal (but not absolutely normal) vapor deposition process (109) wherein the substrate (101, 201) need not be rotated with respect to the vapor deposition target. The vapor deposition process forms an encapsulating layer (111, 207) that can either be utilized as an electrode within the completed device, or that can be removed to allow subsequent construction of additional layers.
