Claim 0:
1. A method for wire-bonding comprising:
feeding a wire through a wire channel of a multifaceted capillary of a wire-bonding machine;
applying a force to press the wire between a bottom surface of the multifaceted capillary and a bonding surface of a substrate, the bottom surface including:
a first face, adjacent to a wire channel, having a first face profile that includes a first surface at a first face angle with the bonding surface;
a second face, adjacent to the first face, having a second face profile that includes a second surface at a second face angle with the bonding surface; and
a third face, adjacent to the second face, having a third face profile that includes a curve having a plateau region that is substantially aligned with the bonding surface, wherein the force includes a first force applied by the first face on the wire, a second force applied by the second face on the wire, and a third force applied by the third face on the wire, the third force being larger than the first force or the second force; and

delivering a power to the wire to raise a temperature of the wire, the raised temperature and the force forming a multi-segment wire-bond.
