Abstract:
A wire bonding method for wire bonding a bonding pad and wire of a semiconductor device, comprising:providing a semiconductor device having a semiconductor element, a bonding pad formed on the semiconductor element, and a wire; preparing the bonding ad by defining thereon a wire bonding region and a test region, the test region being separate from the wire bonding region; forming a first protective film over an upper surface of the bonding pad, so that the first protective film is over both the test region and the wire bonding region; removing the first protective film from over the test region while retaining the first protective film over the wire bonding region; while the first protective film is disposed over the wire bonding region, performing, in the test region of the bonding pad, a characteristic test on the semiconductor element; forming a second protective film over an upper surface of the test region; removing the first protective film from over the wire bonding region; and connecting the wire to the wire bonding region.
