Abstract
Al-Si-Pd alloy with high stress-induced migration resistance was developed for VLSI interconnects. Pd was selected to depress grain boundary diffusion of Al alloys. The microstructures of Al matrices alloyed with Pd and Cu were investigated. The morphologies of precipitation in Al alloy conductors were examined after high-temperature heat treatment. The stress-induced migration resistances of the Al-Si-Pd and Al-Si-Cu were found to be influenced by the microstructures of Al matrices.<>
