  • SHADOW MASK APPARATUS AND METHODS FOR VARIABLE ETCH DEPTHS
    Publication number: 20220238295
    Abstract: Methods of producing grating materials with variable height are provided. In one example, a method may include providing a grating material atop a substrate, and positioning a shadow mask between the grating material and an ion source, wherein the shadow mask is separated from the grating material by a distance. The method may further include etching the grating material using an ion beam passing through a set of openings of the shadow mask, wherein a first depth of a first portion of the grating material is different than a second depth of a second portion of the grating material.
    Type: Application

  • DEVICES AND METHODS FOR VARIABLE ETCH DEPTHS
    Publication number: 20220100078
    Abstract: Methods and devices for producing substrates with variable height features are provided. In one example, a proximity mask may include a plate positioned over a substrate, wherein at least a portion of the plate is separated from the substrate by a distance. The plate may include a first opening and a second opening, wherein the first opening is defined by a first perimeter having a first shape, wherein the second opening is defined by a second perimeter having a second shape, and wherein the first shape is different than the second shape.
