20090007681 | SMALL GAUGE PRESSURE SENSOR USING WAFER BONDING AND ELECTROCHEMICAL ETCH STOPPING - A gauge pressure sensor apparatus and a method of forming the same. A constraint wafer can be partially etched to set the diaphragm size, followed by bonding to a top wafer. The thickness of the top wafer is either the desired diaphragm thickness or is thinned to the desired thickness after bonding. The bonding of top wafer and constraint wafer enables electrochemical etch stopping. This allows the media conduit to be etched through the back of the constraint wafer and an electrical signal produced when the etching reaches the diaphragm. The process prevents the diaphragm from being over-etched. The invention allows the die size to be smaller than die where the diaphragm size is set by etching from the back side. | 01-08-2009 |
20090096040 | Sensor geometry for improved package stress isolation - The sensor geometry for improved package stress isolation is disclosed. A counterbore on the backing plate improves stress isolation properties of the sensor. The counterbore thins the wall of the backing plate maintaining the contact area with the package. The depth and diameter of the counterbore can be adjusted to find geometry for allowing the backing plate to absorb more package stresses. Thinning the wall of the backing plate make it less rigid and allows the backing plate to absorb more of the stresses produced at the interface with the package. The counterbore also keeps a large surface area at the bottom of the backing plate creating a strong bond with the package. | 04-16-2009 |
20090108852 | Structure for capacitive balancing of integrated relative humidity sensor - An improved relative humidity sensor apparatus that provides a more accurate measurement of humidity in the presence of water condensation. A series capacitive sensor includes a thin porous platinum top plate, a humidity sensitive polyimide dielectric, and two metal bottom plates on a semiconductor substrate. The two capacitors can be wired in series such that the metal bottom plates form independent, electrically driven connections. The thin top layer can form a top plate. Changes in humidity affect the humidity sensitive dielectric thereby causing changes in the capacitive value. A P-well layer and a P-plus layer can be added at the perimeter of the substrate to create a path for a parasitic capacitance caused by water condensation to connect to one or more connection nodes, thereby preventing erroneous measurements of humidity in the presence of water condensation. | 04-30-2009 |
20090243107 | NOVEL APPROACH TO HIGH TEMPERATURE WAFER PROCESSING - At temperatures near, and above, 385° C., gold can diffuse into silicon and into some contact materials. Gold, however, is an excellent material because it is corrosion resistant, electrically conductive, and highly reliable. Using an adhesion layer and removing gold from the contact area above and around a contact allows a Micro-Electro-Mechanical Systems device or semiconductor to be subjected to temperatures above 385° C. without risking gold diffusion. Removing the risk of gold diffusion allows further elevated temperature processing. Bonding a device substrate to a carrier substrate can be an elevated temperature process. | 10-01-2009 |
