Abstract
Disclosed are approaches for forming semiconductor patterning features. One method may include providing a plurality of openings through a patterning layer of a semiconductor device, wherein each opening of the plurality of openings is defined by a sidewall of the patterning layer, and wherein the patterning layer is a resist layer or a carbon-based layer. The method may further include removing a portion of the patterning layer by directing a beam of neutral reactive radicals into the sidewall, wherein the beam of neutral reactive radicals is directed at a non-zero angle relative to a perpendicular extending from an upper surface of the patterning layer.
