    Abstract: Methods for processing a substrate are described herein. Methods can include positioning a substrate comprising silicon in a processing chamber, delivering a plasma to the surface of the substrate while biasing the substrate, exposing the surface of the substrate to ammonium fluoride (NH4F), and annealing the substrate to a first temperature to sublimate one or more volatile byproducts.

    Abstract: Methods of depositing pure metal and aluminum alloy metal films. Certain methods comprises contacting a substrate surface with first and second precursors, the first precursor comprising an aluminum precursor selected from dimethylaluminum hydride, alane coordinated to an amine, and a compound having a structure represented by: wherein R is a C1-C6 alkyl group, and the second precursor comprising a metal halide. Other methods relate to sequentially exposing a substrate to a first and second precursor, the first precursor comprising an aluminum precursor as described above, and the second precursor comprising Ti(NR′2)4 or Ta(NR′2)5, wherein R′ is an alkyl, alkenyl, alkynyl, keto or aldehyde group.
