(under the class definition) Process for manufacturing a structure which gives off electrons into free space utilizing a semiconductor substrate.
(1) Note. Some materials may variously be conductive, semiconductive, or insulative. See section A. above for an expansion of what comprises a semiconductor substrate for the purposes of this class.
