Folks: I am seeking references to high vacuum components (or systems) fabricated "on chip" with MEMS. And any info regarding the use of gas evolving explosives or "exploding wire" technology applied to MEMS fabrication, implantation, or power source to drive components.... In particular, I am considering an array of parallel/serial configured turbomolecular pumping elements, or condensation/diffusion pumps with heat exchangers. Also, have "microencapsulated" explosives been used in fabricating devices? ie: gas evolving nitro detonated by laser or e-beam and pumped out. This could provide for "coarse" excavation of large areas of material very quickly. (I have more thoughts on these matters, but need a reality check from experienced engineers!) Thank you for your responses... I am new to this fascinating and inspiring technology. Saul Malamud Pacific Polytechnic Institute agile@serv.net 206-860-7315
