Abstract: A method is provided for forming improved quality interlevel aluminum contacts in semiconductor integrated circuits. A contact opening is formed through an insulating layer. A barrier layer is deposited over the surface of the integrated circuit. An aluminum layer is then deposited at relatively low deposition rates at a temperature which allows improved surface migration of the deposited aluminum atoms. Aluminum deposited under these conditions tends to fill contact vias without the formation of voids. The low temperature deposition step can be initiated by depositing aluminum while a wafer containing the integrated circuit device is being heated from cooler temperatures within the deposition chamber.
