Zusammenfassung:A micromechanical component for a capacitive pressure sensor device includes a substrate; a frame structure that frames a partial surface; a membrane that is tensioned by the frame structure such that a self-supporting region of the membrane extends over the framed partial surface and an internal volume with a reference pressure therein is sealed in an airtight fashion, the self-supporting region of the membrane being deformable by a physical pressure on an external side of the self-supporting region that not equal to the reference pressure; a measurement electrode situated on the framed partial surface; and a reference measurement electrode that is situated on the framed partial surface and is electrically insulated from the measurement electrode.
