Electrical device of semi-conducting material with non-conducting areas

Abstract

An electrical device is provided forming an electrical component or circuit capable of performing such functions as storing, switching or gating electrical signals. The electrical device or circuit is formed at least in part of an anodizable, semi-conducting material by the controlled anodization or oxidation of a selected portion of such material to form a non-conducting portion thereof or a portion thereof in which the semi-conducting material has its capability of conducting electricity substantially reduced. In one form, the portion of the electrical device or circuit which is rendered non-conducting by oxidation or anodization serves to separate semi-conducting portions of the original semi-conducting material from each other. In another form, oxidation or anodization is effected to only partially insulate or isolate portions of the semi-conducting material from each other.
