1. A method comprising:

  • providing a substrate having a material selected from the group consisting of polymeric materials, ceramic materials, glass materials, metal materials, composites thereof, and laminates thereof, wherein the substrate comprises a first surface having an initial surface area; and

    performing a surface-altering process utilizing a partially transmissive mask that allows a fraction of light to pass therethrough, the surface-altering process altering the first surface of the substrate resulting in a surface area of the first surface that is greater than the initial surface area.
