Abstract

A method for fabricating a semiconductor device includes the steps of first forming an aluminum (Al) pad on a substrate, forming a passivation layer on the substrate and an opening exposing the Al pad, forming a cobalt (Co) layer in the opening and on the Al pad, bonding a wire onto the Co layer, and then performing a thermal treatment process to form a Co—Pd alloy on the Al pad.
