    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 contains a different metal selected from titanium, zirconium, hafnium, aluminum, or lanthanum.

    Abstract: A method of monitoring a plasma-based process in a process chamber includes measuring a first temperature at a first location associated with a process chamber during a plasma-based process; and determining a value representative of a first radical species flux associated with the plasma-based process based on the first temperature. The method includes a trained machine learning model to determine if a value representative of a radical species flux satisfies a radical species flux drift threshold.
