ULTRASONIC COMPOSITE VIBRATION DEVICE AND MANUFACTURING APPARATUS OF SEMICONDUCTOR DEVICE
An ultrasonic composite vibration device includes a base end part, an enlarged part, and a tip end part arranged in a straight line from a base end side to a tip end side. The base end part has a transducer generating longitudinal vibration and torsional vibration. The enlarged part has a cross-sectional area larger than the base end part, and the tip end part has a cross-sectional area smaller than the enlarged part. A node of the torsional vibration is located at the enlarged part, and antinodes of the longitudinal vibration and the torsional vibration are located at a base end surface and a tip end surface of the ultrasonic composite vibration device. An axial position and an axial dimension of the enlarged part are set to a position and a dimension at which resonance frequencies of the longitudinal vibration and the torsional vibration are substantially equal.
DETECTION OF FOREIGN PARTICLES DURING WIRE BONDING
A method of bonding wires onto surfaces, an apparatus and a computer program product are disclosed. The method of bonding wires onto surfaces, comprises the steps of: collecting operating characteristics of a bonding tool while forming a wire bond which bonds a wire to a surface; determining whether a possible bonding failure of the wire bond has occurred as indicated by the operating characteristics; and capturing an image of the wire bond to identify whether a foreign body is present on the surface if it is determined that a possible bonding failure has occurred. In this way, imaging of the wire bond is only necessary when the operating characteristics indicate a suspect bonding failure has occurred. This avoids the need to image every bond, while still imaging suspect bonds. This approach helps to significantly increase the throughput of the wire bonding apparatus whilst still identifying and classifying bonding defects due to the presence of a foreign body.
