Embodiments herein provide systems and methods for forming an optical component. A method may include providing a plurality of proximity masks between a plasma source and a workpiece, the workpiece including a plurality of substrates secured thereto. Each of the plurality of substrates may include first and second target areas. The method may further include delivering, from the plasma source, an angled ion beam towards the workpiece, wherein the angled ion beam is then received at one of the plurality of masks. A first proximity mask may include a first set of openings permitting the angled ion beam to pass therethrough to just the first target area of each of the plurality of substrates. A second proximity mask may include a second set of openings permitting the angled ion beam to pass therethrough just to the second target area of each of the plurality of substrates.

System and method for forming diffracted optical element having varied gratings

A method of processing a layer. The method may include providing the layer on a substrate, the substrate defining a substrate plane; directing an ion beam to an exposed surface of the layer in an ion exposure when the substrate is disposed in a first rotational position, the ion beam having a first ion trajectory, the first ion trajectory extending along a first direction, wherein the first ion trajectory forms a non-zero angle of incidence with respect to a perpendicular to the substrate plane; performing a rotation by rotating the substrate with respect to the ion beam about the perpendicular from the first rotational position to a second rotational position; and directing the ion beam to the exposed surface of the layer in an additional ion exposure along the first ion trajectory when the substrate is disposed in the second rotational position.
