  • Patent number: 9252154
    Abstract: An approach to use silicided bit line contacts that do not short to the underlying substrate in memory devices. The approach provides for silicide formation in the bit line contact area, using a process that benefits from being self-aligned to the oxide-nitride-oxide (ONO) nitride edges. A further benefit of the approach is that the bit line contact implant and rapid temperature anneal process can be eliminated. This approach is applicable to embedded flash, integrating high density devices and advanced logic processes.

  • Publication number: 20150285793
    Abstract: A downward or vertical flow-through rapid diagnostic device and assay are provided. The device comprises a test area and reagent storage area, which are linked via a channel. The test area further comprises a reaction zone and an absorbent zone. A capture reagent is immobilized on the reaction zone to detect a target analyte in the fluid test sample. The fluid test sample flows downward or vertically through the reaction zone and into the absorbent zone, with the capture reagent and target analyte forming a two-membered complex that is concentrated in the reaction zone. The reagent storage area comprises a cartridge positioned vertically above the test area and a channel. A reagent used in the assay is housed in the cartridge. Once liberated, the reagent passes through the channel and flows to test area for depositing on the reaction zone. The storage of predetermined amounts of reagents in the diagnostic device reduces the number of manual operations required to produce a result.

An integrated circuit (IC) comprising a substrate, a first device, a second device, and a trench in the substrate and a method of fabricating the same are also discussed. The trench is self-aligned between the first and second devices and comprises a first filled portion and a second filled portion. The first fined portion of the trench comprises a dielectric material that forms a buried trench isolation for providing electrical isolation between the first and second devices. The self-aligned placement of the buried trench isolation allows for higher packing density without negatively affecting the operation of closely spaced devices in a high density IC.

  • Patent number: 8760065
    Abstract: A passive anti-arcing protection components for electronic ballasts of fluorescent lamps. This protection component is a bridge-rectifier-resistor-capacitor network, containing at least a diode, a resistor, and a capacitor. The component's circuitry is electrically connected to the ballast at the lamp side, acting as a low-resistance redirection path for any sudden change in energy. When an arcing condition is about to occur, this protection circuitry absorbs the spark energy, ceasing the arcing condition.

  • Patent number: 8598005
    Abstract: A method and manufacture for memory device fabrication is provided. Spacer formation and junction formation is performed on both: a memory cell region in a core section of a memory device in fabrication, and a high-voltage device region in a periphery section of the memory device in fabrication. The spacer formation and junction formation on both the memory cell region and the high-voltage device region includes performing a rapid thermal anneal. After performing the spacer formation and junction formation on both the memory cell region and the high-voltage device region, spacer formation and junction formation is performed on a low-voltage device region in the periphery section.

  • Patent number: 7728528
    Abstract: A ballast circuit for controlling preheating, ignition or performing dimming of a gas discharge lamp such as a compact fluorescent lamp is disclosed. The ballast circuit has an inverter connected to a pair of input terminals for receiving a supply voltage, a base drive transformer connected to the switching transistor inverter to provide a drive signal, a resonant circuit connected to the switching transistor inverter, and a loading circuit connected to the base drive transformer. The base drive transformer includes a primary winding and a secondary winding set. The loading circuit is adapted for at least temporarily saturating the base drive transformer and thus effecting in the resonant circuit an oscillating frequency different from a natural resonant frequency of the resonant circuit.
