Methods and apparatus for processing a substrate are provided herein. In some embodiments, a method for processing a substrate includes: directing a stream of material from a PVD source toward a surface of a substrate at a first non-perpendicular angle to the plane of the surface to deposit the material on one or more features on the substrate and form a first overhang; etching the layer of the substrate beneath the features selective to the deposited material to form a first part of a pattern; removing the material from the features; directing the stream of material from the PVD source toward the surface of the substrate at a second non-perpendicular angle to the plane of the surface to deposit the material on the features on the substrate and form a second overhang; and etching the layer of the substrate beneath the features selective to the deposited material to form a second part of the pattern.
