Patent ID: 7262124

Claim:
A wire bonding method for bonding a wire between a first bonding point and a second bonding point using a capillary, comprising the steps of: (a) bonding a ball formed on a tip end of the wire to said first bonding point; (b) moving said capillary horizontally and vertically while carrying out loop control, to thereby form a kink in a neck portion of the wire adjacent to said ball; (c) bonding the wire to a top or the vicinity of the top of said ball bonded to said first bonding point; and (d) thereafter, moving said capillary horizontally and vertically to said second bonding point while delivering the wire from said capillary and carrying out loop control, and then bonding the wire to said second bonding point; wherein the step (c) includes crushing a part of the wire and the top of said ball with said capillary to form a crushed part in the wire, and wherein the step (d) includes operating said capillary to form an additional kink in a portion of the wire located between said crushed part and said second bonding point.
