    Abstract: A packaged MEMS transducer device comprising: a die, including: a semiconductor body having a front side and a back side, opposite to one another in a first direction, at least one cavity extending through the semiconductor body between the front side and the back side, and at least one membrane extending on the front side at least partially suspended over the cavity; and a package designed to house the die on an inner surface thereof. The transducer device moreover includes a sealing layer extending on the back side of the semiconductor body for sealing the cavity, and includes a paste layer extending between the sealing layer and the inner surface of the package for firmly coupling the die to the package.

    Abstract: An encapsulated micro-electro-mechanical device, wherein a MEMS chip is encapsulated by a package formed by a first, a second, and a third substrates that are bonded together. The first substrate has a main surface bearing the MEMS chip, the second substrate is bonded to the first substrate and defines a chamber surrounding the MEMS chip, and the third substrate is bonded to the second substrate and upwardly closes the chamber. A grid or mesh structure of electrically conductive material is formed in or on the third substrate and overlies the MEMS chip; the second substrate has a conductive connection structure coating the walls of the chamber, and the first substrate incorporates an electrically conductive region, which forms, together with the conductive layer and the grid or mesh structure, a Faraday cage.
