Abstract:
A process for manufacturing a MEMS pressure sensor having a micromechanical structure envisages: providing a wafer having a substrate of semiconductor material and a top surface; forming a buried cavity entirely contained within the substrate and separated from the top surface by a membrane suspended above the buried cavity; forming a fluidic-communication access for fluidic communication of the membrane with an external environment, set at a pressure the value of which has to be determined; forming, suspended above the membrane, a plate made of polysilicon, separated from the membrane by an empty space; and forming electrical-contact elements for electrical connection of the membrane and of the plate, which are designed to form the plates of a sensing capacitor, the value of capacitance of which is indicative of the value of pressure to be detected. A corresponding MEMS pressure sensor having the micromechanical structure is moreover described.

Claim (Index 15):
The sensor according to  claim 10 , wherein the layer of polysilicon is a first plate region, wherein the access channel is a first access channel, and the empty space is a first empty space, wherein the reference structure comprises:\n a second plate region suspended above a surface portion of the body and set laterally with respect to the membrane, the second plate region being separated from the surface portion by a second empty space; a second access channel configured to provide fluidic communication between the second empty space and the external environment; and reference electrical-contact elements configured to provide electrical communication to the surface portion and the second plate region, wherein the second plate region and the surface portion of the body form the plates of a reference capacitor.
