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 6):
The process according to  claim 3 , further comprising filling the plurality of through holes with a filler layer, and wherein forming a fluidic-communication access channel comprises:\n forming a buried access channel that is contained within the substrate at a distance from the top surface and has a first opening in fluidic communication with the cavity; and wherein the substrate is a wafer, and wherein forming the cavity in the substrate comprises forming a plurality of cavities in the wafer, the plurality of cavities forming membranes that are suspended above respective cavities, the process further comprising sawing the wafer into plurality of dies, each die comprising a cavity and a membrane.
