    Abstract: Methods of producing grating materials with variable height fins are provided. In one example, a method may include providing a mask layer atop a substrate, the mask layer including a first opening over a first processing area and a second opening over a second processing area. The method may further include etching the substrate to recess the first and second processing areas, forming a grating material over the substrate, and etching the grating material in the first and second processing areas to form a plurality of structures oriented at a non-zero angle with respect to a vertical extending from a top surface of the substrate.

    Abstract: A carrier proximity mask and methods of assembling and using the carrier proximity mask may include providing a first carrier body, second carrier body, and set of one or more clamps. The first carrier body may have one or more openings formed as proximity masks to form structures on a first side of a substrate. The first and second carrier bodies may have one or more contact areas to align with one or more contact areas on a first and second sides of the substrate. The set of one or more clamps may clamp the substrate between the first carrier body and the second carrier body at contact areas to suspend work areas of the substrate between the first and second carrier bodies. The openings to define edges to convolve beams to form structures on the substrate.

    Abstract: A plasma source may include a plasma chamber, where the plasma chamber has a first side, defining a first plane and an extraction assembly, disposed adjacent to the side of the plasma chamber, where the extraction assembly includes at least two electrodes. A first electrode may be disposed immediately adjacent the side of the plasma chamber, wherein a second electrode defines a vertical displacement from the first electrode along a first direction, perpendicular to the first plane, wherein the first electrode comprises a first aperture, and the second electrode comprises a second aperture. The first aperture may define a lateral displacement from the second aperture along a second direction, parallel to the first plane, wherein the vertical displacement and the lateral displacement define a non-zero angle of inclination with respect to a perpendicular to the first plane.

    Abstract: Embodiments described herein relate to methods and apparatus for forming gratings having a plurality of fins with different slant angles on a substrate and forming fins with different slant angles on successive substrates using angled etch systems and/or an optical device. The methods include positioning portions of substrates retained on a platen in a path of an ion beam. The substrates have a grating material disposed thereon. The ion beam is configured to contact the grating material at an ion beam angle ϑ relative to a surface normal of the substrates and form gratings in the grating material.
