Patent ID: 8563392

Claim:
A method for forming a capacitor stack comprising: forming a first material above a substrate, wherein the first material is operable as a first electrode of the capacitor stack, wherein the first material is one of a conductive metal oxide, conductive metal silicide, conductive metal carbide, conductive metal nitride, or combinations thereof; forming a second material above the first material, wherein the second material is operable as a dielectric of the capacitor stack; and forming a third material above the second material, wherein the third material is operable as a second electrode of the capacitor stack, and wherein the forming of the first material, comprises: a) providing the substrate to a reaction chamber; b) pulsing an electron donating compound into the reaction chamber to form an adsorbed electron donating compound on the substrate; c) purging the reaction chamber to remove non-adsorbed electron donating compound; d) pulsing a metal-containing precursor into the reaction chamber to react with the adsorbed electron donating compound on the substrate, forming an electron donating compound stabilized metal-containing layer on the substrate; e) purging the reaction chamber to remove non-adsorbed metal-containing precursor; f) pulsing an reactant gas into the reaction chamber to react with the electron donating compound stabilized metal-containing layer, forming a metal compound layer on the substrate; g) purging the reaction chamber to remove unreacted reactant gas; h) repeating steps b) through g) until a desired thickness of the metal compound layer is reached.
