1. A method of texturing a surface of a substrate, comprising:

  • providing a substrate;

    distributing separate particles of an overlayer material in a substantially random pattern over at least a part of a surface of the substrate;

    subjecting the distributed separate particles to a predetermined environment, which reduces the size of the particles; and

    using the substantially random pattern of separate particles as a mask for a subsequent processing of the substrate.
