  • Patent number: 11670516
    Abstract: Various embodiments herein relate to methods, apparatus, and systems for etching a feature in a substrate. Typically the feature is etched in a dielectric-containing stack. The etching process involves cyclically etching the feature and depositing a protective film on sidewalls of the partially etched feature. These stages are repeated until the feature reaches its final depth. The protective film may have a particular composition, for example including at least one of a tungsten carbonitride, a tungsten sulfide, tin, a tin-containing compound, molybdenum, a molybdenum-containing compound, a ruthenium carbonitride, a ruthenium sulfide, an aluminum carbonitride, an aluminum sulfide, zirconium, and a zirconium-containing compound. A number of optional steps may be taken including, for example, doping the mask layer, pre-treating the substrate prior to deposition, removing the protective film from the sidewalls, and oxidizing any remaining protective film.

    Abstract: Fabricating a semiconductor substrate by (a) vertical etching a feature having sidewalls and a depth into one or more layers formed on the semiconductor substrate and (b) depositing an amorphous carbon liner onto the sidewalls of the feature. Steps (a) and optionally (b) are iterated until the vertical etch feature has reached a desired depth. With each iteration of (a), the feature is vertical etched deeper into the one or more layers, while the amorphous carbon liner resists lateral etching of the sidewalls of the feature. With each optional iteration of (b), the deposited amorphous carbon liner on the sidewalls of the feature is replenished.
