- How about generating a pattern of randomly distributed 1 micron circles of a
- metal on the glass. If the metal did not etch in HF or a F plasma then a very
- rough surface could be generated by etching the glass around these circles.
- With an isotropic etch and close spacing of the circles a field of random
- glass cones would be produced. The metal could then be stripped off and
- further processing could continue. Let me know whether this idea works out.
