Claim:
1. A method of depositing a film on a substrate, comprising: placing the substrate on a support; depositing material comprising aluminum onto the substrate while the substrate is supported by but is unclamped relative to the support and under a condition in which the temperature of the substrate increases, to thereby form a first metallic layer consisting of aluminum or an aluminum alloy on the substrate; and subsequently depositing material comprising aluminum directly onto the first layer to form a second metallic layer, consisting of aluminum or an aluminum alloy, continuously on the first layer, and wherein the depositing of the material to form the second layer is carried out while the substrate is supported by and clamped to a support and is actively cooled to a temperature of less than about 22° C., and until the second layer is thicker than the first layer.
