Patent ID: 7371675

Claim:
A method of wire bonding, comprising: providing a carrier with at least a first pad and a semiconductor chip arranged on the carrier with at least a second pad, the second pad being smaller than the first pad; forming a conductive first stud bump on the second pad; and forming a first bonding wire that has two terminal portions, which are respectively bonded to the first pad and the first stud bump to electrically connect the first pad and the second pad, wherein one end of the terminal portion includes a first prominence formed by ball bonding and the first prominence has a larger diameter than the first stud bump, the first stud bump is bonded to the second pad by ball bonding using a wire that has a smaller diameter than the first bonding wire, and the forming of the first stud bump and the forming of the first bonding wire connected to the first pad are performed by an identical wire bonding machine by alternately providing wires having different diameters to a capillary.
