    Abstract: Provided are methods of depositing tantalum-containing films via atomic layer deposition and/or chemical vapor deposition. The method comprises exposing a substrate surface to flows of a first precursor comprising TaClxR5-x, TaBrxR5-x or TaIxR5-x, wherein R is a non-halide ligand, and a second precursor comprising an aluminum-containing compound, wherein x has a value in the range of 1 to 4. The R group may be C1-C5 alkyl, and specifically methyl. The resulting films comprise tantalum, aluminum and/or carbon. Certain other methods relate to reacting Ta2Cl10 with a coordinating ligand to provide TaCl5 coordinated to the ligand. A substrate surface may be exposed to flows of a first precursor and second precursor, the first precursor comprising the TaCl5 coordinated to a ligand, the second precursor comprising an aluminum-containing compound.

    Abstract: Embodiments described herein relate to a thermal chlorine gas cleaning process. In one embodiment, a method for cleaning N-Metal film deposition in a processing chamber includes positioning a dummy substrate on a substrate support. The processing chamber is heated to at least about 50 degrees Celsius. The method further includes flowing chlorine gas into the processing chamber and evacuating chlorine gas from the processing chamber. In another embodiment, a method for cleaning titanium aluminide film deposition in a processing chamber includes heating the processing chamber to a temperature between about 70 about degrees Celsius and about 100 degrees Celsius, wherein the processing chamber and the substrate support include one or more fluid channels configured to heat or cool the processing chamber and the substrate support.
