Abstract:
A wire bonding method for bonding wires to connection pads, comprising:touching the wires to a bonding wedge and applying a predetermined load between the wires and connection pads; then vibrating the bonding wedge with a predetermined ultrasonic wave vibration with the predetermined load for a predetermined time providing the predetermined ultrasonic wave vibration with the predetermined load between the wires and connection pads, while measuring an amount of wire transformation until the amount of wire transformation reaches a predetermined set value, the amount of wire transformation being set at an initial value, wherein the amount of wire transformation is achieved by the predetermined load after the predetermined time in the time controlling step; and wherein the set value for the amount of wire transformation in the transformation amount controlling step increases according to the number of times of the use of the bonding wedge.
