For a few holes, you could try a wire of the desired diameter in a small
drill press, diamond abrasive, and a support for the glass that controls the
force to small values, such as setting the glass on urethane foam.


Dear MEMS colleagues,

    As a part of my thesis I am interested in making several small =
diameter holes (100-200 micron) in a thin layer of glass (400-500 =
micron), along a 20 mm line. Then I need to fill the holes with gold or =
any other metal.
    I would like to know if anyone knows any methods to drill or etch =
those holes in glass ( Pyrex, BK-7, CdTe, BaF2 or any other material =
that allows transmission in the visible and IR wavelengths as well).
I would appreciate if anyone can tell me of a manufacturer that can make =
these holes.=20
   =20
P.S.   I choose glass because of its relative high thermal isolation =
property.

Thank you in advance,

Danny Klein
