Abstract

A method of manufacturing a semiconductor device is provided. A bonding tool with a wire tail extending out of the tip thereof is lowered to bring the tip of the wire tail into contact with a bonding surface of the semiconductor device. Next, the bonding tool in a direction intersecting with the axial direction of the bonding tool (Z direction) is moved to bend the wire tail with the tip of the wire tail in contact with the bonding surface. Then the bonding tool is lowered to form the wire tail into a predetermined shape such that the tip of the wire tail points upward. And then, a wire looping step, a second bonding step and a wire cutting step are performed. This allows the wire tail to be formed easily and efficiently into a predetermined shape.
