Abstract

Embodiments are directed to a method and resulting structures for smoothing the sidewall roughness of a post-etched film. A sacrificial layer is formed on a substrate. A patterned mask is formed by removing portions of the sacrificial layer to expose a surface of the substrate. The sidewalls of the patterned mask are smoothed and a target layer is formed over the patterned mask and the substrate. Portions of the target layer are removed to expose a surface of the patterned mask and the patterned mask is removed.
