Abstract

Methods and systems for depositing a layer comprising silicon oxide on the substrate are disclosed. Exemplary methods include cyclical deposition methods that include providing a first silicon precursor to the reaction chamber, providing a second silicon precursor, and using a reactant or a non-reactant gas forming silicon oxide on a surface of the substrate. Exemplary methods can further include a treatment step.
