Abstract:
1. A vertical MEMS gyroscope by horizontal driving, comprising: a substrate; a support layer fixed on an upper surface of a particular area of the substrate; a driving structure floating above the substrate and having a portion thereof fixed to an 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 detecting 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 an upper surface of the substrate; a cap wafer positioned above the driving structure and the detecting structure, and bonded with the substrate, the cap wafer defining an interior space above the driving structure; and a fixed vertical displacement detection electrode formed on an underside of the cap wafer above the detecting surface, for detecting displacement of the detecting structure in the vertical direction.
