Abstract
A method for depositing a boron doped silicon germanium (SiGe) film is disclosed. The method may include: providing a substrate within a reaction chamber; heating the substrate to a deposition temperature; flowing a silicon precursor, a germanium precursor, and a halide gas into the reaction chamber through a first gas injector; flowing a boron dopant precursor into the reaction chamber through a second gas injector independent from the first gas injector; contacting the substrate with the silicon precursor, the germanium precursor, the halide gas and the boron dopant precursor; and depositing the boron doped silicon germanium (SiGe) film over a surface of the substrate.
