    摘要: A micromechanical sensor integrated on a chip, includes a semiconductor substrate, an electronic circuit, a void, a diaphragm, a counterelectrode and valve openings connecting a volume of the void to its surroundings. The valve openings are directed toward an upper surface of the wafer, and the counterelectrode is a component part of a coating plane that extends over the entire chip surface, so that the electronic semiconductor circuit can be applied to the coating plane by known semiconductor technology. A method for producing the micromechanical sensor as well as a microphone or a pressure sensor having the micromechanical sensor, are also provided.
