COPPER PAD FOR COPPER WIRE BONDING

摘要

An integrated circuit package comprising an integrated circuit that includes transistors coupled to copper interconnect structures. The integrated circuit package also comprises copper pads located on the integrated circuit and directly contacting uppermost ones of the copper interconnect structures. Each of copper pads has a thickness of at least about 2 microns. The integrated circuit package further comprises copper wires pressure-welded directly to the copper pads.
