    摘要: A method of thermally coupling a flow tube or like component to a thermal sensor comprises bonding the component to the thermal sensor such that thermally conductive portions formed on the component are thermally coupled to corresponding sensing/heating elements disposed on the thermal sensor. The method can be employed to form a capillary mass flow sensor system. Thermally conductive portions, such as metal bands, can be formed on the outer surface of a capillary tube for bonding with corresponding resistive heat sensing and heating elements disposed on the substrate of a micro mass flow sensor. Bonding metal pads can be formed on the sensor surface preparatory to solder bonding the tube metal bands to the resistive sensing and heating elements.

    摘要: A pixel having a reflector situated on a substrate. A temperature sensitive resistor may be situated over at least a portion of the reflector. An insulator may be situated on the resistor. The resistor and insulator may effectively be very thin films. A flat metal mesh or grid may be situated on the insulator. The grid, insulator and resistor may be supported by two or more posts at approximately one-fourth of a wavelength from the reflector. The wavelength may be that of the radiation to be sensed by the pixel. The thermal mass of the combination of the temperature sensitive resistor, insulator and grid may be less than several times the thermal mass of the grid. Since the grid may be so thin for low noise performance and high sensitivity, the grid can have a flatness assured to a desired extent with stiffeners attached to portions of it.

    摘要: A method for etching a diaphragm pressure sensor based on a hybrid anisotropic etching process. A substrate with an epitaxial etch stop layer can be etched utilizing an etching process in order to form a diaphragm at a selective portion of the substrate. The diaphragm can be oriented at an angle (e.g., 45 degree) with respect to the substrate in order to avoid an uncertain beveled portion in a stress/strain field of the diaphragm. The diaphragm can be further etched utilizing an etch finishing process to create an anisotropic edge portion on the major areas of the diaphragm and optimize the thickness and size of the diaphragm. Such an approach provides an enhanced diaphragm structure with respect to a wide range of pressure sensor applications.

    摘要: A sensor having a nanotube grown on and supported by thermal bimorph structures. The nanotube rests on a heat sink during sensing gas or a liquid and is moved from the heat sink when the nanotube is heated to desorb gas or liquid from it. The heatsink may function as a gate along with the bimorph structures as the other terminals of a transistor. Current-voltage and current-gate voltage characteristics may be obtained of the nanotube as a device like a transistor. These characteristics may provide information on a gas or liquid absorbed by the nanotube.

    摘要: A method includes forming a plurality of mirror periods, stacking the mirror periods, and bonding the mirror periods together to form a high reflectance mirror. At least one of the mirror periods is formed by bonding a first semiconductor layer to a first side of a film layer (where the film layer is formed on a second semiconductor layer), forming an opening through the second semiconductor layer to expose the film layer, and cutting through the first semiconductor layer, the film layer, and the second semiconductor layer. The first semiconductor layer could include a high resistivity silicon wafer, the film layer could include an oxide film, and the second semiconductor layer could include a silicon wafer. The high resistivity silicon wafer could be approximately 110 μm thick, and the silicon wafer could be approximately 125 μm thick. The opening through the second semiconductor layer could be 1.25 cm to 1.75 cm in width.
