Abstract
A method is provided. The method may include providing a substrate, the substrate comprising a substrate surface, the substrate surface having a three-dimensional shape. The method may further include directing a depositing species from a deposition source to the substrate surface, wherein a layer is deposited on a deposition region of the substrate surface. The method may include performing a substrate scan during the directing or after the directing to transport the substrate from a first position to a second position. The method may also include directing angled ions to the substrate surface, in a presence of the layer, wherein the layer is sputter-etched from a first portion of the deposition region, and wherein the layer remains in a second portion of the deposition region.
