    摘要: A vertical MEMS gyroscope operated by horizontal driving includes a substrate, a support layer fixed on an upper surface of an area of the substrate, a driving structure floating above the substrate and having a portion fixed to the upper surface of the support layer and another portion in parallel with the fixed portion, the driving structure having a predetermined area capable of vibrating in a predetermined direction parallel to the substrate, a detection structure fixed to the driving structure on a same plane as the driving structure, and having a predetermined area capable of vibrating in a vertical direction with respect to the substrate, a cap wafer bonded with the substrate positioned above the driving structure and the detection structure, and a fixed vertical displacement detection electrode formed at a predetermined location of an underside of the cap wafer, for detecting displacement of the detection structure in the vertical direction.
