Abstract
In some embodiments of the present invention, methods are developed wherein a gas flow of an electron donating compound (EDC) is introduced in sequence with a precursor pulse and alters the deposition of the precursor material. In some embodiments, the EDC pulse is introduced sequentially with the precursor pulse with a purge step used to remove the non-adsorbed EDC from the process chamber before the precursor is introduced. In some embodiments, the EDC pulse is introduced using a vapor draw technique or a bubbler technique. In some embodiments, the EDC pulse is introduced in the same gas distribution manifold as the precursor pulse. In some embodiments, the EDC pulse is introduced in a separate gas distribution manifold from the precursor pulse.
