  • Patent number: 7291481
    Abstract: The release by trichomonads of a hydrolase that hydrolyzes a narrowly defined class of substrates at a low pH without interference from hydrolases that are unrelated to trichomoniasis is the basis for a selective diagnostic assay for trichomoniasis that measures hydrolysis of any of these substrates by vaginal fluid at a low pH. Selective assays for trichomoniasis are also obtained by removing particulate matter from a sample of vaginal fluid to extract a fraction devoid of particles greater than a selected size, and where desired, combining the extracted fraction with any of certain specified hydrolase inhibitors, then testing the fraction for enzymatic hydrolase activity. These qualities of trichomoniasis are the basis for a series of diagnostic tests and test devices that produce results that are detectable by visual and other means with a high degree of accuracy.

The identifier identifies the semiconductor chip from other semiconductor chips manufactured using the fabrication process. The circuit elements can be selected from the group of bipolar transistors, MOS transistors, light detecting pixel elements, and memory cells. The chip identification method is particularly useful for identifying image sensor chips where the dark current values or the defective pixel locations can be used as the chip identifier.

  • Patent number: 7291508
    Abstract: A P-type diffusion diode is used as a probe point for an infrared laser probing system. The P-type diffusion diode probe point may be formed on a semiconductor substrate and connected to an integrated circuit thereon. The P-type diffusion diode probe point may result in higher signal-to-noise ratios in testing of integrated circuits at lower voltages.

  • Patent number: 7291509
    Abstract: A semiconductor material (5) is grown in the windows (4) of a patterned mask layer (3) on a substrate (1). The semiconductor material (5) grows together over the mask layer (3) with semiconductor material (5) from adjacent windows to form a largely planar surface (7), which is suitable for the further growth of a component layer sequence (9). Through the choice of a substrate (1) having a smaller thermal expansion coefficient than the semiconductor material (5), particularly strong tensile stresses occur in the semiconductor material (5) or the component layer sequence (9) during cooling, which stresses lead to cracking. Since the semiconductor material (5) that has grown together forms a so-called coalescence region (6), having a high density of imperfections in the crystal lattice, these thermally governed cracks (13) are more likely to occur in this region.

  • Patent number: 7291510
    Abstract: The inventive method for manufacturing a semiconductor device is a method for manufacturing a semiconductor device using irradiation with laser light to partition a substrate having semiconductor layers formed thereon, with gallium contained in at least one of the substrate and the semiconductor layers, wherein the method comprises: forming grooves to be used as boundaries between individual substrates by irradiating the substrate along partitioning locations with laser light, immersing the substrate into an acid solution, and partitioning the substrate into individual substrates along the boundaries where grooves are formed. In this manner, it provides a method for manufacturing a semiconductor device in which, during the partitioning of a gallium-containing semiconductor device substrate, deposits of gallium compounds adhered during laser irradiation are removed, partitioning surfaces are formed flat and uniform, and the incidence of electrode continuity failures and resin peeling is low.

  • Patent number: 7291511
    Abstract: A drive electrode to which a voltage for allowing a vibrator to vibrate is applied and first and second detection electrodes extending in the longitudinal direction of the vibrator in parallel to each other are formed as the upper electrode such that the drive electrode is interposed between the first and second detection electrodes and does not contact with the detection electrodes. In the case where there is a difference between the detection signals detected in the first and second detection electrodes when a voltage is applied between the lower electrode and drive electrode to allow the vibrator to vibrate at a vertical resonance frequency, a laser light is irradiated to a desired portion of the vibrator to apply grinding operation based on detection signals detected in the first and second detection electrodes, thereby adjusting the shape of the vibrator.

  • Patent number: 7291512
    Abstract: A valve structure comprises an elastomeric block formed with first and second microfabricated recesses separated by a membrane portion of the elastomeric block. The valve is actuated by positioning a compliant electrode on a first side of the first recess proximate to and in physical communication with the membrane. Where the valve is to be electrostatically actuated, a second electrode is positioned on a second side of the first recess opposite the first side. Application of a potential difference across the electrodes causes the compliant electrode and the membrane to be attracted into the flow channel. Where the valve is to be electrostrictively actuated, a second electrode is positioned on the same side of the recess as the compliant electrode. Application of a potential difference across the electrodes causes the electrodes to be attracted such that elastomer membrane portion material between them is compressed and bows into the flow channel.

  • Patent number: 7291513
    Abstract: A method is disclosed for making a wafer-level package for a plurality of MEMS devices. The method involves preparing a MEMS wafer and a lid wafer, each having respective bonding structures. The lid and MEMS wafers are then bonded together through the bonding structures. The wafers are substantially free of alkali metals and/or chlorine. IN a preferred embodiment, each wafer has a seed layer, a structural underlayer and an anti-oxidation layer. A solder layer, normally formed on the lid wafer, bonds the two wafers together.

  • Patent number: 7291514
    Abstract: Langmuir-Blodgett films are provided in which a molecule is chemically bonded with a bottom electrode substrate as part of a crossed wire device comprising two electrodes and a molecular layer therebetween. The molecule, which comprises a switchable moiety and a connecting moiety, is provided with a photolabile capping group attached to the connecting moiety. The photolabile capping group temporarily caps the reactive connecting group of the molecule. The capped molecules are processed to form a LB film on the water-air interface of water. The films are then exposed to UV light. The photolabile capping group decomposes to give back the connecting group, which remains in the water. As the uncapped LB films are transferred to a bottom electrode substrate, the surface of the electrode reacts with the reactive connecting group of the molecule to form a chemically bonded LB layer on the substrate, thereby providing improved LB films.
