  • MANUFACTURE OF SURFACE RELIEF STRUCTURES
    Publication number: 20220342297
    Abstract: A method and apparatus for the etching of variable depth features in a substrate is described. Movement of the substrate relative to an etchant (e.g. into or out of the etchant) during the etching process is utilised to provide a varying etch time, and hence depth, across the substrate, and in various examples this is enabled without requiring a varying mask.
