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. Lonnie Houck llh@mvuzr.att.com
