.Application of UV depth lithography in micro system technology[J].Optoelectronics Letters,2008,4(1):1-4 Application of UV depth lithography in micro system technology Stephanus Büttgenbach Stephanus Büttgenbach(Institute for Microtechnology, Technical University of Braunschweig Langer Kamp 8, 38106 Braunschweig, Germany) ; Marco Feldmann(Institute for Microtechnology, Technical University of Braunschweig Langer Kamp 8, 38106 Braunschweig, Germany) ; Abstract:       This letter reports on new types of photo resists allowing UV-light exposure of thick layers. Optimized processes Cthat for the positive resistAZ 9260 and the negative resist Epon SU-8 have been developed enabling the fabrication of high aspect ratio metallic and polymer micro components. The high potential of this technology will be demonstrated on the basis of two examples, a variable reluctance micro motor with compensated attractive force and an optical microphone developed for application in electro-magnetic interference en environments.
