Patent ID: 7755152

Claim:
A semiconductor component configured as a micromechanical diaphragm sensor, comprising: a semiconductor substrate having a first region of a first doping, wherein a cavity is provided in at least one part of the first region and that is located at least partially below the diaphragm; a second region having a second doping distinguishable from the first doping, the second region being provided one of in and on the surface of the semiconductor substrate, wherein at least one part of the second region is configured as crosspieces, and wherein at least one part of the second region is provided as a framing for the first region, wherein at least one part of the second region is configured as crosspieces, and wherein at least one part of the second region is provided as a framing for the first region; and a diaphragm of a monocrystalline, epitaxial layer mounted on the crosspieces, wherein the crosspieces are located above at least one part of the cavity; wherein a sealing layer is deposited above the second region, wherein the sealing layer seals the surface above the first region, starting out from at least one part of the crosspieces of the second region, in at least one of lateral direction and vertical direction, wherein the diaphragm is formed by the deposited sealing layer, and wherein the diaphragm includes at least a part of the crosspieces, and wherein the framing is a vertical extension of the first region into a depth of the semiconductor substrate starting from the surface of the semiconductor substrate.
