Abstract: A method for forming an accelerometer including the steps of providing a wafer of doped silicon, growing an oxide layer on the wafer, and forming an aperture in the oxide layer. The method further includes the steps of forming a layer of polysilicon on the wafer such that a portion of the polysilicon passes through the aperture and contacts the wafer, and etching the layer of polysilicon to form a beam and a capacitor plate. The wafer is then etched to form a response mass and a support, at least part of the response mass being located below the capacitor plate. Finally, the oxide layer is etched to separate the response mass from the support and from the capacitor plate, the response mass being coupled to the beam by polysilicon received through the aperture.

Abstract: A media compatible package (100) for a pressure sensing device is made from a non-corrosive, highly chemical resistant material. The package includes a base (105) which holds a printed circuit board (115) having a pressure sensor (18) mounted thereon. A sealing member (45) is placed on the circuit board encircling the pressure sensor and a diaphragm (30) is disposed on the sealing member. A fluid port (130) is attached to the base and compressingly engages the diaphragm creating a sealed chamber around the pressure sensor. The sealed chamber is filled with a pressure transmissive fluid (21) such as oil through a fill hole (140) provided in the printed circuit board. This configuration allows the sensor package to be easily assembled with ordinary components and provides a design where all exposed surfaces of the package can be made from a highly non-corrosive material.
