  • Publication number: 20140248772
    Abstract: Embodiments of the invention provide methods for depositing a material on a substrate within a processing chamber during a vapor deposition process, such as an atomic layer deposition (ALD) process. In one embodiment, a method is provided which includes sequentially exposing the substrate to a first precursor gas and at least a second precursor gas while depositing a material on the substrate during the ALD process, and continuously or periodically exposing the substrate to a treatment gas prior to and/or during the ALD process. The deposition rate of the material being deposited may be controlled by varying the amount of treatment gas exposed to the substrate. In one example, tantalum nitride is deposited on the substrate and the alkylamino metal precursor gas contains a tantalum precursor, such as pentakis(dimethylamino) tantalum (PDMAT), the second precursor gas contains a nitrogen precursor, such as ammonia, and the treatment gas contains dimethylamine (DMA).

  • Publication number: 20140248692
    Abstract: Systems and methods for calculating a predictive index of identity of a nucleic acid sample using polymorphic genetic marker data are provided. In one embodiment, a predictive index of identity of the nucleic acid sample is calculated using a value from a second set of data from a polymorphic genetic marker that is not linked to a polymorphic genetic marker used to produce a first set of data. In another embodiment, the predictive index of identity is calculated using a value from a second set of data from a polymorphic genetic marker that is linked to a polymorphic genetic marker used to produce the first set of data. Systems and methods for generating an identifier for a biological sample and for verifying a relationship between a biological sample and an identifier are also provided. The identifier is an encoding of a set of values for polymorphic genetic markers.

  • Publication number: 20140247238
    Abstract: A system and method for improved accuracy in the detection of a stylus on a touch sensitive surface of an electronic device, such as a tablet. A dual method of detection is employed including electromagnetic induction detection of the stylus as it is in the vicinity of the screen of the electronic device, as well as capacitive detection of the stylus tip as it contacts the touch screen. The electronic device detects the presence of the top of the stylus and provides the general coordinates of its position. Then, as touches occur on the surface of the device, e.g., the stylus tip as well as the various parts of the user's hand, the system uses the coordinates supplied from the electromagnetic induction detection to very quickly and accurately pinpoint the actual location of the stylus input on the surface of the device.
