Wire ball bonding in semiconductor devices
A method of interconnecting components of a semiconductor device using wire bonding is presented. The method includes creating a free air ball at a first end of an aluminum wire that has a coating surrounding the aluminum wire, wherein the coating comprises palladium, and wherein the free air ball is substantially free of the coating. The method further includes the step of bonding the free air ball to a bond pad on a semiconductor chip, the bond pad having an aluminum surface layer, wherein the resultant ball bond and the bond pad form a substantially homogenous, aluminum-to-aluminum bond. The method may further include bonding a second, opposing end of the coated-aluminum wire to a bond site separate from the semiconductor chip, the bond site having a palladium surface layer, wherein the second end of the coated-aluminum wire and the bond site form a substantially homogenous, palladium-to-palladium bond.
