Micromechanical component and manufacturing method for a micromechanical component

摘要

A micromechanical component is described having a substrate which has at least one stator electrode fixedly mounted with respect to the substrate, a movable mass having at least one actuator electrode fixedly mounted with respect to the movable mass, and at least one spring via which the movable mass is displaceable. The movable mass is structured from the substrate with the aid of at least one separating trench, at least one outer stator electrode spans at least one section of the at least one separating trench and/or of the movable mass, the at least one actuator electrode protrudes between the at least one outer stator electrode and the substrate, and at least one inner stator electrode protrudes between the at least one actuator electrode and the substrate. A related manufacturing method is also described for a micromechanical component.

1. A micromechanical component, comprising:
a substrate having at least one stator electrode which is fixedly mounted with respect to the substrate; a movable mass having at least one actuator electrode which is fixedly mounted with respect to the movable mass; and at least one spring via which the movable mass is connected to the substrate so that the movable mass is displaceable with respect to the substrate at least from a first position into a second position, wherein the movable mass is structured from the substrate with at least one separating trench; at least one outer stator electrode spanning at least one section of the at least one separating trench or the movable mass, wherein the at least one actuator electrode protrudes at least into a first space between the at least one outer stator electrode and the substrate; and at least one inner stator electrode protruding at least into a second space between the at least one actuator electrode and the substrate.
