Abstract:
Provided are methods of depositing films comprising alloys of aluminum, which may be suitable as N-metal films. Certain methods comprise exposing a substrate surface to a metal halide precursor comprising a metal halide selected from TiCl4, TaCl5 and HfCl4 to provide a metal halide at the substrate surface; purging metal halide; exposing the substrate surface to an alkyl aluminum precursor comprising one or more of dimethyaluminum hydride, diethylhydridoaluminum, methyldihydroaluminum, and an alkyl aluminum hydrides of the formula [(CxHy)3-aAlHa]n, wherein x has a value of 1 to 3, y has a value of 2x+2, a has a value of 1 to 2, and n has a value of 1 to 4; and exposing the substrate surface to an alane-containing precursor comprising one or more of dimethylethylamine alane, methylpyrrolidinealane, di(methylpyrolidine)alane, and trimethyl amine alane borane. Other methods comprise exposing a substrate surface to a metal precursor and trimethyl amine alane borane.
