Abstract:
Techniques for ball bonding wires in an integrated circuit are provided which allow formation of desired wire bond profile shapes for optimal performance. A wire is ball bonded to a first bond site in the integrated circuit with a bonding tool and at least one bend is formed in the wire. The wire is terminated at a second bond site with the bonding tool, thereby creating a wire bond profile. The technique is repeated for a plurality of additional wire bonds of the integrated circuit, and at least two wire bond profiles in the integrated circuit are substantially perpendicular to one another at a crossing point of the profiles.
