Abstract
A micromechanical inertial sensor that includes three component planes, namely a bottom part, a center part and a cover part. The center part is a silicon wafer in which a cardan-type (i.e. gimbal) structure with two oscillating elements is formed. A plate is formed in the silicon wafer which can be pivoted about a rotational axis lying in the wafer plane. Metallized portions or conductive layers form an exciter unit and set the gimbal structure oscillating. The inventive sensor further comprises a device for detecting the displacement of the plate. In addition, a method for manufacturing a micromechanical inertial sensor.
