Appeal No. 1996-1552
Application 08/241,976
29 being the sole independent claim on appeal.
The subject matter on appeal is directed to a method of producing a field emitter device. As
indicated in the specification (page 3), a field emission current output can be controlled using the field
emitter device formed with the method recited in claims 25 to 29 on appeal.
Representative independent method claim 29 is reproduced below:
29. A method of producing a field emitter device, comprising the steps of:
(a) forming a field effect transistor structure having a drain which that is without an external
electrical contact; and
(b) monolithically forming an electron field emitter structure on the drain of the field effect
transistor.
