  • Abstract
    An angular resonance silicon gyroscope was fabricated by deep RIE and XeF2 gas etching. Using these two etching methods, a sensor which has beams in the center of the thickness of its mass could be fabricated very precisely. The sensor has a glass-silicon-glass structure and its resonator is excited electrostatically and the vibration caused by the angular rate is measured capacitively. Sensor sensitivity obtained was 2.1 fF/(deg/sec)
