  • Publication number: 20160306965
    Abstract: Systems and methods are disclosed for associating an entity with a risk score that may indicate a security threat associated with the entity's activity. An exemplary method may involve monitoring the activity of a subset of the set of entities (e.g., entities included in a watch list) by executing a search query against events indicating the activity of the subset of entities. The events may be associated with timestamps and may include machine data. Executing the search query may produce search results that pertain to activity of a particular entity from the subset. The search results may be evaluated based on a triggering condition corresponding to the statistical baseline. When the triggering condition is met, a risk score for the particular entity may be updated. The updated risk score may be displayed to a user via a graphical user interface (GUI).

  • Publication number: 20160283244
    Abstract: In accordance with some embodiments of the present invention, a branch prediction unit for an embedded controller may be placed in association with the instruction fetch unit instead of the decode stage. In addition, the branch prediction unit may include no branch predictor. Also, the return address stack may be associated with the instruction decode stage and is structurally separate from the branch prediction unit. In some cases, this arrangement reduces the area of the branch prediction unit, as well as power consumption.

  • Patent number: 9076888
    Abstract: Methods and structures are provided for full silicidation of recessed silicon. Silicon is provided within a trench. A mixture of metals is provided over the silicon in which one of the metals diffuses more readily in silicon than silicon does in the metal, and another of the metals diffuses less readily in silicon than silicon does in the metal. An exemplary mixture includes 80% nickel and 20% cobalt. The silicon within the trench is allowed to fully silicide without void formation, despite a relatively high aspect ratio for the trench. Among other devices, recessed access devices (RADs) can be formed by the method for memory arrays.

  • Patent number: 8349687
    Abstract: A transistor gate forming method includes forming a metal layer within a line opening and forming a fill layer within the opening over the metal layer. The fill layer is substantially selectively etchable with respect to the metal layer. A transistor structure includes a line opening, a dielectric layer within the opening, a metal layer over the dielectric layer within the opening, and a fill layer over the metal layer within the opening. The metal layer/fill layer combination exhibits less intrinsic less than would otherwise exist if the fill layer were replaced by an increased thickness of the metal layer. The inventions apply at least to 3-D transistor structures.

  • Patent number: 8202806
    Abstract: A method of fabricating an integrated circuit having reduced threshold voltage shift is provided. A nonconducting region is formed on the semiconductor substrate and active regions are formed on the semiconductor substrate. The active regions are separated by the nonconducting region. A barrier layer and a dielectric layer are deposited over the nonconducting region and over the active regions. Heat is applied to the integrated circuit causing the barrier layer to anneal.

  • Patent number: 8089128
    Abstract: A transistor gate forming method includes forming a first and a second transistor gate. Each of the two gates includes a lower metal layer and an upper metal layer. The lower metal layer of the first gate originates from an as-deposited material exhibiting a work function the same as exhibited in an as-deposited material from which the lower metal layer of the second gate originates. However, the first gate's lower metal layer exhibits a modified work function different from a work function exhibited by the second gate's lower metal layer. The first gate's lower metal layer may contain less oxygen and/or carbon in comparison to the second gate's lower metal layer. The first gate's lower metal layer may contain more nitrogen in comparison to the second gate's lower metal layer. The first gate may be a n-channel gate and the second gate may be a p-channel gate.
