Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
47 words
Method for the preparation of electronic and electro-optical components and circuits, which comprises melting a meltable conducting polymer in contact with at least one substrate surface of a material other than the conducting polymer to form a boundary surface between the conducting polymer and said other material.
Claim 2
Dependent Claim
47 words
Method for the preparation of electronic and electro-optical components and circuits, which comprises melting a meltable conducting polymer in contact with at least one substrate surface of a material other than the conducting polymer to form a boundary surface between the conducting polymer and said other material.
Claim 3
Dependent Claim
55 words
Method according to claim 1 wherein a boundary surface between said conducting polymer and said other material which is a metal is formed by pressing the surfaces of the conducting polymer and the metal against each other under sufficient heat to melt the polymer, whereby the polymer and the metal become fixed to each other.
Claim 4
Dependent Claim
49 words
Method according to claim 1 wherein the other material is an insulating material and the boundary surface is formed by pressing the polymer and insulating material against each other under sufficient heat to melt the polymer in such manner that the polymer and insulator become fixed to each other.
Claim 5
Dependent Claim
42 words
Method according to claim 1 wherein the other material is a semiconductor and the boundary surface is formed by pressing the conducting polymer and semiconductor together under sufficient heat to melt the polymer whereby the conducting polymer becomes fixed to the semiconductor.
Claim 6
Dependent Claim
15 words
Method according to claim 2 wherein the metal provides ohmic contact with the contacting polymer.
Claim 7
Dependent Claim
15 words
Method according to claim 2 wherein the metal is Au, Cr, Ti, In or Pt.
Claim 8
Dependent Claim
14 words
Method according to claim 3 wherein the insulator is an inorganic or polymeric insulator.
Claim 9
Dependent Claim
22 words
Method according to claim 4 wherein the semiconductor is Si, an amorphous silicon hydride (a-Si;H), GaAs, CuInSe or a polymer semiconducting polymer.
Claim 10
Dependent Claim
18 words
Method according to claim 1 wherein the conducting polymer is a meltable poly(3-octylthiophene), poly(3-alkylthiophene), poly(alkylthiophene vinyl) or polyalkylpyrrolidine.
