  • Publication number: 20150270365
    Abstract: Angled directional ion beams are directed to sidewalls of a gate structure that straddles at least one semiconductor fin. The directions of the angled directional ion beams are contained within a vertical plane that is parallel to the sidewalls of the at least one semiconductor. A pair of gate spacers are formed on sidewalls of the gate structure by accumulation of the deposited dielectric material from the angled directional ion beams and without use of an anisotropic etch, while the sidewalls of the semiconductor fins parallel to the directional ion beams remain physically exposed. A selective epitaxy process can be performed to form raised active regions by growing a semiconductor material from the sidewalls of the semiconductor fins.

  • Publication number: 20150270179
    Abstract: A device is created by forming a layer of dielectric material on a silicon-containing region of a semiconductor substrate. An opening is created through the layer of dielectric material, the opening having a bottom and exposing the silicon-containing region. A metal stack is formed within the opening. The metal stack includes at least a first metal film on the silicon-containing region and a second gettering metal film on the first metal film. The metal stack is annealed to cause oxygen to migrate from the substrate to the gettering metal film. A first liner is formed within the opening. A fill metal is deposited in the opening.

  • Publication number: 20150200291
    Abstract: After formation of gate structures over semiconductor fins and prior to formation of raised active regions, a directional ion beam is employed to form a dielectric material portion on end walls of semiconductor fins that are perpendicular to the lengthwise direction of the semiconductor fins. The angle of the directional ion beam is selected to be with a vertical plane including the lengthwise direction of the semiconductor fins, thereby avoiding formation of the dielectric material portion on lengthwise sidewalls of the semiconductor fins. Selective epitaxy of semiconductor material is performed to grow raised active regions from sidewall surfaces of the semiconductor fins. Optionally, horizontal portions of the dielectric material portion may be removed prior to the selective epitaxy process. Further, the dielectric material portion may optionally be removed after the selective epitaxy process.

  • Patent number: 9008797
    Abstract: An implantable medical electrical lead includes a plurality of conductors that extend continuously, without any intermediary junctions, between a plurality of electrodes and a corresponding plurality of contact members of an in-line connector terminal. A junction between each conductor and the corresponding contact member is preferably formed by first fitting a conductive sleeve, which is coupled to a proximal portion of the conductor, into an eyelet feature of the contact member, which is mounted on a strut member, and then welding the sleeve to the contact member at a pre-formed slot of the contact member, which extends along an external recessed surface thereof. The assembly of the connector terminal preferably completes the construction of the lead, wherein the proximal portion of each conductor is positioned in a helical path, which extends between an elongate body of the lead and the connector terminal, and along which a grip zone is formed.

  • Publication number: 20150008488
    Abstract: A method of manufacturing a semiconductor structure includes forming a raised source-drain region in a semiconductor substrate adjacent to a dummy gate and forming a chemical mechanical polish (CMP) stop layer over the gate structure and above a top surface of the semiconductor substrate. A first ILD layer is formed above the CMP stop layer. The first ILD layer is removed to a portion of the CMP stop layer located above the gate structure and a portion of the CMP stop layer located above the gate structure is also removed to expose the dummy gate. The dummy gate is replaced with a metal gate and the metal gate is polished until the CMP stop layer located above the raised source-drain region is reached.

  • Publication number: 20150007630
    Abstract: An exemplary system for crimping a prosthetic valve comprises a radially expandable and compressible prosthetic valve, a crimping device positioned around the valve and configured to reduce the diameter of the valve to a delivery configuration, and a sterile package enclosing the valve and the crimping device. The valve can be pre-assembled in a partially crimped configuration within the crimping device. After removing the sterile packaging, the crimping device can be used to crimp the valve from the partially crimped configuration to the delivery configuration, such as by twisting a knob on the crimping device. The system can further comprise at least a portion of a delivery catheter within the sterile package, wherein the valve is pre-mounted on or adjacent to an inflatable balloon of the delivery catheter, such that the valve can be crimped onto the delivery catheter using the crimping device.

  • Publication number: 20140172906
    Abstract: Methods and systems may provide for obtaining a query image of a scene, wherein the query image includes embedded information and represents the scene at a time of capture. The embedded information may include location data and perspective data. Additionally, user input may be received, wherein the user input identifies a different time than the time of capture. A time-shifted image of the scene may be obtained based on the user input and the embedded information in the query image. Crowd sources and/or other public information sources may also be used to obtain the time-shifted image. In one example, the time-shifted image represents the scene at the different time.
