Patent ID: 8837754

Claim:
A MEMS transducer, comprising: a micromechanical sensing structure; a package that includes a substrate and a lid, the substrate having a first surface that is opposite to a second surface, the lid is coupled to the first surface of said substrate, the package includes an internal cavity in which said micromechanical sensing structure is housed, said lid including: a cap layer having a first surface and a second surface opposite to one another, said first surface including an external face of said package and said second surface facing said first surface of the substrate inside said package, the micromechanical sensing structure being coupled to said second surface of said cap layer, inside said package; and a wall structure positioned between said cap layer and said substrate, the wall structure having a coupling face that faces the first surface of the substrate; first electrical-connection elements formed on the first surface of the substrate; and second electrical-connection elements formed on the coupling face of said wall structure, the second electrical-connection elements being coupled to the first electrical-connection elements and being configured to electrically couple said micromechanical sensing structure to said first electrical-connection elements, at least two of the second electrical-connection elements being electrically separated from each other by a groove formed into the wall structure.
