Abstract:
1. A method of forming a material over a substrate, comprising at least one iteration of the following sequence within a reaction chamber: utilizing a first precursor to form a first species comprising a first metal selected from the group consisting of aluminum, lanthanides, niobium, tantalum, yttrium and zirconium across at least a portion of the substrate; prior to providing any reactant, utilizing a second precursor within the reaction chamber, in the substantial absence of the first precursor, to form a second species in contact with the first species, the second precursor having a different composition than the first precursor and comprising a second metal selected from the group consisting of aluminum, hafnium, lanthanides, niobium, tantalum, titanium, yttrium and zirconium; and providing a reactant within the reaction chamber, in the substantial absence of the first and second precursors, and reacting said reactant with at least one of the first and second species.
