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. P.S. I choose glass because of its relative high thermal isolation property. Thank you in advance, Danny Klein ----------------------------------------------------- Danny Klein Faculty of Mechanical Engineering Technion, Israel Institute of Technology Haifa, 32000 Israel Tel: 972-4-8292946 Email: dannykl@tx.technion.ac.il ----------------------------------------------------
