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.
An electrical device comprising a device supporting substate, a semi-conducting material on said substrate, said semi-conducting material having a portion thereof converted to its non-conducting oxide to a selected depth with non-converted semi-conducting material adjacent at least two opposed sides of said non-conducting oxide, said non-conducting oxide comprising means for restraining the flow of electrons between the separated non-converted portions of said semi-conducting material.

Claim 3
Dependent Claim
28 words
An electrical device in accordance with claim 1 wherein said oxide portion of said semi-conducting material serves as a barrier between portions of said semi-conducting material adjacent thereto.
Claim 4
Dependent Claim
24 words
An electrical device in accordance with claim 1 wherein said oxide portion of said semi-conducting material extends completely through said layer of semi-conducting material.
Claim 5
Dependent Claim
25 words
An electrical device in accordance with claim 1 wherein said oxide portion of said semi-conducting material extends only partially through said layer of semi-conducting material.
