Patent ID: 8796792

Claim:
A microelectromechanical system (MEMS) device, comprising: a body having a thickness, a first surface and an opposite second surface; an opening through the thickness of the body, the opening extending from the first to the second surface; metal leads embedded in the first surface of the body; a metal foil anchored in the body and extending at least partially across the opening at the first surface; and an integrated circuit chip flip-assembled to the leads on the first surface, the chip spanning at least partially across the foil, separated from the foil by a gap; wherein the metal leads include a first set and a second set, the leads of the first set enabling electrical interconnection between the foil and the integrated circuit, the leads of the second set enabling solder contacts to external parts; wherein the leads of the first set, together with the foil, are positioned in a first plane and the leads of the second set are positioned in a second plane offset from the first plane; and wherein the metal leads further include a third set positioned in the first plane, the third set configured as a metal seal ring encircling the opening.
