Patent ID: 8220337

Claim:
A micromechanical capacitive pressure sensor having a layered structure, comprising: at least one deflectable carrier element for at least one deflectable measuring electrode in a first layer plane; and at least one stationary carrier structure for at least one stationary counter electrode in a second layer plane; wherein: the first and second layer planes are situated parallel to each other; the deflectable carrier element is suspended in a closed cavity of the layered structure between two diaphragms oriented essentially perpendicularly to the first and second layer planes, the two diaphragms delimiting the closed cavity on two opposite sides; at least one pressure connection aperture is provided, and at least one of the two diaphragms is subjected to a pressure being measured via the at least one pressure connection aperture; and the deflectable carrier element is connected to the two diaphragms in such a way that diaphragm deformations cause an essentially parallel shift of the measuring electrode relative to the counter electrode, the degree of overlap between the measuring electrode and the counter electrode changing during the parallel shift of the measuring electrode relative to the counter electrode.
