Claim 18:
19. A method for wire-bonding comprising:
applying a force to press a wire between a bottom surface of a 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; 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 including the plateau region defined by the curve of the third face.
