Claim Text:
1. A wire bonding method for forming a wire interconnection including a wedge wire bond, the method comprising steps in the following sequence: forming the wedge wire bond on a wire using a capillary; securing, using a wire holding device located above a wire clamp and the capillary, the wire while the wire clamp is open and not clamping onto the wire; thereafter, lifting the wire clamp and the capillary relative to the wire in a direction away from the wedge wire bond and towards the wire holding device so as to pay out a length of wire from the capillary; at a predetermined height of the capillary, closing the wire clamp to clamp onto the wire; and thereafter moving the capillary and wire clamp further away from the wedge wire bond to cause the wire to break away from the wedge wire bond so as to form the wire tail with a desired length extending from the capillary.
