  • Patent number: 9298806
    Abstract: A system and method configured for analyzing transactions in a distributed ledger. The system may identify transactions where addresses and/or groupings of addresses are co-spent together and determine whether the addresses and/or groupings of addresses should be associated with each other. Addresses may be associated with each other in a grouping of addresses and/or potential grouping of addresses because they likely belong to the same entity. The system may identify different strengths and/or confidence levels of groupings of addresses and/or potential groupings of addresses. Strong groupings, relatively strong potential groupings, and/or other groupings of addresses, potential groupings of addresses, and/or groups may be grouped, associated, analyzed, and/or presented together. As such, the system may provide a comprehensive analysis of addresses associated with a given entity.

  • Patent number: 9214528
    Abstract: A method for forming an enhancement mode GaN HFET device with an isolation area that is self-aligned to a contact opening or metal mask window. Advantageously, the method does not require a dedicated isolation mask and the associated process steps, thus reducing manufacturing costs. The method includes providing an EPI structure including a substrate, a buffer layer a GaN layer and a barrier layer. A dielectric layer is formed over the barrier layer and openings are formed in the dielectric layer for device contact openings and an isolation contact opening. A metal layer is then formed over the dielectric layer and a photoresist film is deposited above each of the device contact openings. The metal layer is then etched to form a metal mask window above the isolation contact opening and the barrier and GaN layer are etched at the portion that is exposed by the isolation contact opening in the dielectric layer.

  • Patent number: 9171911
    Abstract: An integrated semiconductor device which includes a substrate layer, a buffer layer formed on the substrate layer, a gallium nitride layer formed on the buffer layer, and a barrier layer formed on the gallium nitride layer. Ohmic contacts for a plurality of transistor devices are formed on the barrier layer. Specifically, a plurality of first ohmic contacts for the first transistor device are formed on a first portion of the surface of the barrier layer, and a plurality of second ohmic contacts for the second transistor device are formed on a second portion of the surface of the barrier layer. In addition, one or more gate structures formed on a third portion of the surface of the barrier between the first and second transistor devices. Preferably, the one or more gate structures and the spaces between the gate structures and the source contacts of the transistor devices collectively form an isolation region that electrically isolates the first transistor device from the second transistor device.

  • Patent number: 9142637
    Abstract: III-nitride materials are used to form isolation structures in high voltage ICs to isolate low voltage and high voltage functions on a monolithic power IC. Critical performance parameters are improved using III-nitride materials, due to the improved breakdown performance and thermal performance available in III-nitride semiconductor materials. An isolation structure may include a dielectric layer that is epitaxially grown using a III-nitride material to provide a simplified manufacturing process. The process permits the use of planar manufacturing technology to avoid additional manufacturing costs. High voltage power ICs have improved performance in a smaller package in comparison to corresponding silicon structures.

  • Patent number: 8981503
    Abstract: An STT MTJ cell is formed with a magnetic anisotropy of its free and reference layers that is perpendicular to their planes of formation. The reference layer of the cell is an SAF multilayered structure with a single magnetic domain to enhance the bi-stability of the magnetoresistive states of the cell. The free layer of the cell is etched back laterally from the reference layer, so that the fringing stray field of the reference layer is no more than 15% of the coercivity of the free layer and has minimal effect on the free layer.
