The SU-8 thick resist process can be used to fabricate the high aspect ratio microstructures that can add the strength and the electrical properties of microdevices. Moreover, the SU-8 resist is used as the body material of micromechanism; this can directly avoid the stripped difficulty and inconvenient assembly like MUMPs process. Besides, the microactuator fabricated by SU-8 can make the driving response larger than the one fabricated by metal. We have finished electrostatic actuator that was all in one not assembled. Advantages of electrostatic actuator are low cost, decrease microstructures assembled tolerances and increase active range of micromechanism by being driven indirectly. In our study, Electrostatic actuators that was sputtered metal, are driven by DC 150 V.SU-8厚膜光阻蝕刻釋放技術連桿驅動機構靜電式微致動器SU-8 thick resistetch release techniquelinkage-drive mechanismelectrostatic actuator
