Claim:
1. A MEMS sensor device assembly comprising: a single first semiconductor die having an internal surface and an opposite, external surface, a micromechanical detection structure integrated in the first semiconductor die at the internal surface; and a single second semiconductor die having an internal surface and an opposite, external surface, an ASIC embedded in the second semiconductor die, the ASIC being operatively coupled to said micromechanical detection structure, the internal surface of the second semiconductor die coupled to the internal surface of said first semiconductor die, the external surfaces of the first and second semiconductor dice being exposed outer surfaces of the assembly, at least one of the external surfaces being configured to be placed in direct contact with a structure external to the assembly, the second semiconductor die having a cavity that at least partially receives the micromechanical detection structure of the first semiconductor die.
