Abstract

Al and AI-1%Si 900 nanometer thin films were deposited on 100 nanometer Cu films on thermally oxidized (100 nanometer) Si wafers. The Al and Cu films were deposited using evaporation techniques, and the Al-1%Si film was sputter deposited. Different thin film samples were heated in vacuum to 175, 250, 330 and 400°C for 1 hour. The various annealed and original samples were compared using surface morphology, as well as composition versus sample depth. Differences between the Al and Al-1%Si samples are discussed.
