Pressure sensor having high detection performance and optimized manufacturing

A process for manufacturing a pressure sensor, comprising:

• forming, from a wafer, a deformable detection element suspended on the wafer, extending at a distance from the wafer along a first direction, and configured to undergo a deformation as a function of a pressure to be detected;
• and
• forming, from the wafer, an anchoring structure configured to support the deformable detection element over the substrate,
• wherein forming the anchoring structure comprises:
• forming a plurality of anchoring portions extending from the wafer, coupled to the deformable detection element, and arranged at a distance from each other along a second direction transversal to the first direction;
• and
• forming a structural region extending between the anchoring portions along the second direction and having at least one release opening extending through the structural region.
