    Abstract: Methods for processing substrates are provided herein. In some embodiments, a method for processing substrates includes providing to a process chamber a substrate comprising an exposed dielectric layer having a feature formed therein. A mask layer comprising titanium nitride may be selectively deposited atop corners of the feature. A barrier layer may be selectively deposited atop the mask layer and into a bottom portion of the feature. The barrier layer deposited on the bottom portion of the feature may be etched to redistribute at least a portion of the barrier layer onto sidewalls of the feature.
