Abstract
A packaged MEMS device, wherein at least two support structures are stacked on each other and are formed both by a support layer and a wall layer coupled to each other and delimiting a respective chamber. The chamber of the first support structure is upwardly delimited by the support layer of the second support structure. A first and a second dice are accommodated in a respective chamber, carried by the respective support layer of the first support structure. The support layer of the second support structure has a through hole allowing wire connections to directly couple the first and the second dice. A lid substrate, coupled to the second support structure, closes the chamber of the second support structure.
