Abstract
Abstract Electrical connection means are formed on surface means of an electronic device. One end of the electrical connection means is connected to electrical contact means provided by the electronic device. The free end of the electrical connection means is engaged and lifted from the surface means thereby lifting at least a section of the electrical connection means free of the surface means and the free end is electrically connected to another electrical contact means.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
142 words
A method of forming an electrical connection member on a semi-conductor device and connecting one end thereof to an electrical conductive member comprising the steps of: fabricating a junction member in said semiconductor device; depositing a layer of metal onto said semiconductor device with a portion of the metal layer adhering to and electrically connected to said junction member; applying photoresist onto said metal layer; masking said photoresist thereby outlining an electrical connection member including said junction and a peelable section extending outwardly therefrom along said semiconductor device; etching said photoresist in its unmasked section thereby leaving said electrical connection member and junction; engaging an outer end of said peelable section; lifting said outer end thereby peeling said peelable section from said semiconductor device; bending said peelable section back across said junction; and connecting said outer end to said electrical conductive means.
Claim 2
Independent Claim
142 words
A method of forming an electrical connection member on a semi-conductor device and connecting one end thereof to an electrical conductive member comprising the steps of: fabricating a junction member in said semiconductor device; depositing a layer of metal onto said semiconductor device with a portion of the metal layer adhering to and electrically connected to said junction member; applying photoresist onto said metal layer; masking said photoresist thereby outlining an electrical connection member including said junction and a peelable section extending outwardly therefrom along said semiconductor device; etching said photoresist in its unmasked section thereby leaving said electrical connection member and junction; engaging an outer end of said peelable section; lifting said outer end thereby peeling said peelable section from said semiconductor device; bending said peelable section back across said junction; and connecting said outer end to said electrical conductive means.
Claim 3
Dependent Claim
25 words
The method of claim 1 wherein said junction has thereon a deposit of metal to form a metal adhesion layer for said electrical connection member.
Claim 4
Dependent Claim
27 words

Claim 5
Dependent Claim
13 words
A method according to claim 1 wherein said layer of metal is gold.
Claim 6
Dependent Claim
15 words
A method according to claim 1 wherein said electrical connection member comprises a plurality thereof.
