Abstract:
A method of manufacturing a field emitter cell, comprising the steps of:providing a conductive substrate layer; forming a catalyst layer on said conductive substrate layer; forming an insulating layer either on an upper surface of said catalyst layer or directly on said substrate layer; forming a conductive gate layer on an upper surface of said insulating layer; making at least one perforation through said gate layer that extends downward into said insulating layer thereby forming a gate aperture in said gate layer, with said perforation comprising sidewalls and being in electrical contact with either said catalyst layer or substrate layer; forming a standoff layer on said gate layer, said sidewalls, and said catalyst layer or substrate layer; removing the portion of said standoff layer on said gate layer, catalyst or substrate layer while retaining said standoff layer on said sidewalls; and growing an electrically conductive group of nanofilaments on said catalyst layer conductively associated with said substrate layer, said group of nanofilaments being electrically isolated from the said gate layer.
