Dear All, I am a very new comer in this list as well as in the field of MEMS. I've been wrestling with a question for couple of days. The question is: Is it possible to make a microhole of a diameter of 1 um on a microlayer of a thickness of 5 um and control (increase or decrease) the diameter of the microhole by any way such as electric field, magnetic field, or heating etc.? Any help would be highly appriciated. Thanking you Abmi Get your free and private web-based e-mail from our new partner at http://www.mailexcite.com
