Abstract

Abstract A method of bonding an electrical conductor to a contact of an integrated circuit (IC) device comprises bonding the conductor to a support member and to a contact of the IC device. The conductor is then severed to release the IC device and conductor from the support. This allows the IC device to be tested while connected to the support member and provides it with a conductor lead for connection to a carrier for use.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 53 words
A method of bonding an electrical conductor to a contact of an integrated circuit device comprising bonding a conductor to a support member and to a contact of an integrated circuit device; and subsequently severing said bonded conductor to release said integrated circuit device and the bonded conductor from said conductor support member.
Claim 2
Independent Claim 53 words
A method of bonding an electrical conductor to a contact of an integrated circuit device comprising bonding a conductor to a support member and to a contact of an integrated circuit device; and subsequently severing said bonded conductor to release said integrated circuit device and the bonded conductor from said conductor support member.
Claim 3
Dependent Claim 15 words
A method according to claim 1, wherein said integrated circuit device comprises a silicon chip.
Claim 4
Dependent Claim 20 words
A method according to claim 1, wherein said conductor is in the form of one of a wire and ribbon.
Claim 5
Dependent Claim 26 words
A method according to claim 1, wherein said conductor is first bonded to said support member and the free end subsequently joined to said circuit device.
Claim 6
Dependent Claim 20 words
A method according to claim 4, wherein said conductor is broken off beyond the bond with said integrated circuit device.
Claim 7
Dependent Claim 18 words
A method according to claim 1, wherein the bonding steps are carried out using a wedge bonding technique.
Claim 8
Dependent Claim 30 words
A method according to claim 1, wherein the temporary bonds on the support member are reinforced by bonding a cap or lid to entrap said conductor on the support member.
Claim 9
Dependent Claim 17 words
A method according to claim 1, wherein said conductor is in the form of a rectangular ribbon.
Claim 10
Dependent Claim 26 words
A method according to claim 1, wherein subsequent to said severing step, the integrated circuit device is connected to a host device via the severed conductor.
