TECHNIQUE TO DEPOSIT METAL-CONTAINING SIDEWALL PASSIVATION FOR HIGH ASPECT RATIO CYLINDER ETCH

Various embodiments herein relate to methods, apparatus and systems for forming a recessed feature in a dielectric-containing stack on a semiconductor substrate. Separate etching and deposition operations are employed in a cyclic manner. Each etching operation partially etches the feature. Each deposition operation forms a protective coating (e.g., a metal-containing coating) on the sidewalls of the feature to prevent lateral etch of the dielectric material during the etching operations. The protective coating may be deposited using methods that result in formation of the protective coating along substantially the entire length of the sidewalls. The protective coating may be deposited using particular reaction mechanisms that result in substantially complete sidewall coating. Metal-containing coatings have been shown to provide particularly good resistance to lateral etch during the etching operation. In some cases, a bilayer approach may be used to deposit the protective coating on sidewalls of partially etched features.
