  • Abstract
    A novel MEMS gyroscope sensing pendulum was etched with KOH by isothermal magnetic stirrer, and the etching rate relation with temperature and concentration was investigated in the mask of SiO2. The results reveal that a rate of etching Si(100), Si(100) to SiO2 and Si(100) to Si(111) is 4.0 μm/min, 550:1 and 90:1 respectively, a uniformity etching surface and ideal etching rate are obtained for a concentration of 30%KOH at 110°C, meet the production of MEMS gyroscope requirements.
