Abstract:
Embodiments described and discussed herein provide methods for selectively depositing a metal oxides on a substrate. In one or more embodiments, methods for forming a metal oxide material includes positioning a substrate within a processing chamber, where the substrate has passivated and non-passivated surfaces, exposing the substrate to a first metal alkoxide precursor to selectively deposit a first metal oxide layer on or over the non-passivated surface, and exposing the substrate to a second metal alkoxide precursor to selectively deposit a second metal oxide layer on the first metal oxide layer. The method also includes sequentially repeating exposing the substrate to the first and second metal alkoxide precursors to produce a laminate film containing alternating layers of the first and second metal oxide layers. Each of the first and second metal alkoxide precursors contain different types of metals which are selected from titanium, zirconium, hafnium, aluminum, or lanthanum.
