Abstract
In this paper, we report a research effort to design, analyze, and fabricate a novel type of microaccelerometer using UV lithography of SU-8 and UV-LIGA process. Instead of using SU-8 only as photo resist as in silicon-based MEMS fabrication processes, cured SU-8 was used as the primary structural material in fabricating the micro sensors. A commercial software, ANSYS, was used to design the suitable size for the spring-mass and capacitors to achieve the desired bandwidth and the maximum sensitivity. The preliminary results obtained so far have proved the feasibility of fabrication of micro accelerometer using cured SU-8 polymer as the primary structural material and using UV-LIGA as the major fabrication tool.
