Patent ID: 6925875

Claim:
A micro machined accelerometer package including: a integrated circuit having a top surface and a bottom surface and having a micro machined accelerometer formed in the integrated circuit, the accelerometer including a mass cantilevered from the remainder of the integrated circuit to be movable out of the plane of the integrated circuit, one or more motion detectors for detecting motion of the mass, processing circuitry and one or more bond pads exposed on the top surface for communicating detected accelerations; a first hollow molded cap bonded to the top surface over at least part of the accelerometer to define a first cavity into which the cantilevered mass may move, wherein the first molded cap is bonded to the integrated circuit such that the cap covers the mass, the motion detectors and the processing circuitry and wherein the cap does not cover the bond pads; the accelerometer further including a second cap bonded to the second surface of the integrated circuit over at least part of the accelerometer to define a second cavity into which the cantilevered mass may move.
