Abstract
Methods of semiconductor processing may include providing a hydrogen-containing precursor to a processing region of a semiconductor processing chamber. A substrate may be disposed on a substrate support within the processing region. A layer of silicon-and-nitrogen-containing material may be disposed on the substrate. The methods may include forming plasma effluents of the hydrogen-containing precursor. The methods may include contacting the layer of silicon-and-nitrogen-containing material with plasma effluents of the hydrogen-containing precursor. The contacting may etch a portion of the layer of silicon-and-nitrogen-containing material.
