Abstract
Exemplary processing methods may include providing a silicon-containing precursor and a carbon-containing precursor to a processing region of a semiconductor processing chamber. A substrate may be housed in the processing region. The substrate may define a feature within the substrate. The methods may include forming plasma effluents of the silicon-containing precursor and the carbon-containing precursor. The methods may include depositing a silicon-and-carbon-containing material on the substrate. The methods may include providing a hydrogen-containing precursor to the processing region of the semiconductor processing chamber, forming plasma effluents of the hydrogen-containing precursor, and etching the silicon-and-carbon-containing material from a sidewall of the feature within the substrate. The methods may include providing a nitrogen-containing precursor to the processing region of the semiconductor processing chamber, forming plasma effluents of the nitrogen-containing precursor, and doping the silicon-and-carbon-containing material with nitrogen.
