Abstract
Abstract An integrated semiconductor is described in which all the interconnected circuit elements, including barrier layers and contacts, comprise only metal-semiconductor junctions, ion implanted junctions, or insulating layers, produced by low temperature processes only, to avoid detrimental effects on a supporting substrate.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
30 words
An integrated semiconductor circuit as set forth in claim 1 wherein the circuit is monolithic with all the circuit elements incorporated in a common semiconductor body serving as a substrate.
Claim 2
Dependent Claim
24 words
An integrated semiconductor circuit as set forth in claim 1 wherein the substrate is a plastic sheet incapable of withstanding temperatures exceeding 400* C.
Claim 3
Dependent Claim
43 words
An integrated semiconductor circuit as set forth in claim 1 wherein at least several of the circuit elements are electrically isolated from one another by ion-implanted striplike regions within the semiconductor body and of a conductivity type opposite to that of the body.
Claim 4
Dependent Claim
51 words
An integrated semiconductor ciRcuit as set forth in claim 1 wherein at least several of the circuit elements are electrically isolated from one another in the body by a Schottky barrier formed by a metal strip provided on the body and reverse biased to form a depletion layer through the body.
