  • Publication number: 20110062560
    Abstract: Semiconductor devices containing a CVD BPSG layer and an undoped CVD oxide cap layer are described. The cap layer can be any silicon oxide material with a thickness between about 50 ? and about 350 ?. The cap layer may be formed using a low temperature CVD process that is controlled for density by adjusting the amount of silicon precursor in the gas-phase. In some embodiments, the cap layer is deposited on the BPSG layer followed immediately by the BPSG film deposition prior to any annealing of the BPSG layer. The cap layer may prevent dopant out-diffusion and/or out-gassing during storage and high-temperature annealing, and moisture penetration into the BPSG layer, as well as suppress defect nucleation on the as-deposited BPSG surface and defect formation during high temperature annealing, while still allowing flow ability of the BPSG layer. Other embodiments are also described.

  • Patent number: 7206625
    Abstract: An invention is disclosed that provides an apparatus, method and system for the collection of physiological electrical potential signals. In one embodiment, the apparatus comprises integrating amplifier and an electrode into a combined unit for attaching or affixing to a subject (e.g., an animal or a human). Resulting from the extremely small or short connection between the conductive portion of the electrode and the amplifier, significantly less noise is introduced into the signal detected by the amplifier. The amplifier thus amplifies a signal with a much higher signal-to-noise ratio as compared with conventional electrode to lead wire to amplifier arrangements.

  • Publication number: 20070081600
    Abstract: The invention relates to electrical network communications engineering and can be used for automatic data acquisition from intrusion and fire-alarm sensors, electric meters, heat, water and gas consumption meters and from the fiscal memory of cash control monitors. Said invention makes it possible to substentially reduce the energy consumption by the slave nodes of a system and/or increase the range of action thereof. In order to encode each symbol of transmitted data, a random or pseudorandom set of differences of initial pairs of nearest harmonic pairs are used. Said difference sets of the initial phases are selected in such a way that the peak factor of an added signal is minimised. When a fire-alarm sensor is actuated, it is sufficient to transmit only one symbol to an alarm panel which, unambiguously identifies the location of the active sensor and as a rule is embodied in the form of a conventional number or address pre-allocated to said sensor.
