Abstract

PURPOSE: To provide a semiconductor devices in which a conventional wire bonding terminal is converted to a bump structure suitable for wireless bonding by providing a pad which is formed by cutting and taking off part of a conventional aluminum connector pad for wire bonding.
CONSTITUTION: The surface of a semiconductor substrate 11 is covered with an insulating film 12. On top of the insulating film 12 is formed a pad 13, that is one part of a conventional aluminum connector pad to be used for wire bonding. Part of the pad 13 is covered with a protecting film 14, while a multi-layered conductor is provided in the portion corresponding to the other part, cut and taken off, of the aluminum connector pad. The multi-layered conductor is overlaid with a protruding bump 16, to top of which is connected a lead 17, so that the provision of a protrode is made available to existing semiconductor devices without protruded electrodes by not necessarily correcting the existing aluminum wiring patterns by using masks to the minumum necessity. The absence of the aluminum pad just below the gold bump serves to avoid the occurrence of cracks the otherwise might be inevitable due to heat and pressure applied during the bonding processes.
