Patent ID: 8093700

Claim:
A module, comprising: a semiconductor lid portion; a packaging portion attached to the lid portion, wherein the packaging portion comprises a plurality of vias and metallization connected to at least some of the plurality of vias; a carrier portion, wherein: a first semiconductor die is attached to the carrier portion; the packaging portion is attached to the carrier portion so that the packaging portion is over the carrier portion and the semiconductor die is within an opening in the packaging portion; the semiconductor lid portion and the carrier portion form a first air gap around the first semiconductor die, and the semiconductor lid portion is a first semiconductor substrate, the packaging portion is a second semiconductor substrate, and the carrier portion is a third semiconductor substrate; and a second semiconductor die is attached to the third semiconductor substrate; the first semiconductor substrate and the third semiconductor substrate form a second air gap around the second semiconductor die; and the plurality of vias and the metallization are laterally disposed between the first semiconductor die and the second semiconductor die.
