Abstract:
A micromechanical sensor, comprising:a support of silicon substrate having an epitaxial layer of polycrystalline silicon applied thereon, a part of the epitaxial layer being laid bare by an etching process to form at least one micromechanical deflection part, the at least micromechanical deflection part connected, at least one side, to the silicon substrate via a support region made of single-crystal silicon, the at least one micromechanical deflection part being deflected out of an initial position upon application of a force to the micromechanical sensor, the micromechanical sensor further comprising an evaluation circuit for evaluating the deflection of the micromechanical deflection part, wherein the micromechanical deflection part includes a plate supported at its corners, and wherein the micromechanical sensor is a capacitive acceleration sensor with lateral sensitivity.
