Patent ID: 8025201

Claim:
Apparatus for performing a wire-bonding operation in an integrated circuit, the apparatus comprising: a bonding tool; a memory; and at least one processor, coupled to the memory; wherein the processor is programmed to cause the bonding tool to perform, for each of a plurality of wires in the integrated circuit, an operation of ball bonding the wire to a corresponding first bond site in the integrated circuit; an operation of forming at least one bend in the wire; and an operation of terminating the wire at a corresponding second bond site, thereby creating a plurality of bonded wires having respective profiles and being associated with respective pairs of first and second bond sites; wherein the profiles of a first set of the plurality of bonded wires in the integrated circuit are substantially perpendicular to respective profiles of a second set of the plurality of bonded wires in the integrated circuit at respective crossing points thereof, with the profiles of the first and second sets of bonded wires residing in respective planes that are substantially parallel to one another, and either the first bond sites or the second bond sites associated with said first and second sets of bonded wires all being located on a given die of the integrated circuit; wherein the operation of forming at least one bend in the wire comprises an operation of applying at least one reverse motion with the bonding tool; wherein a first reverse motion forming a bend adjacent to the first bond site is applied at a greater distance from the first bond site along a length of the wire for a first wire from the first set of the plurality of bonded wires than for a second wire from the second set of the plurality of bonded wires; and wherein the first set of the plurality of bonded wires has a lower bond profile height relative to the second set of the plurality of bonded wires.
