  • Patent number: 12342611
    Abstract: Integrated circuit structures having source or drain structures with vertical trenches are described. In an example, an integrated circuit structure includes a fin having a lower fin portion and an upper fin portion. A gate stack is over the upper fin portion of the fin, the gate stack having a first side opposite a second side. A first source or drain structure includes an epitaxial structure embedded in the fin at the first side of the gate stack. A second source or drain structure includes an epitaxial structure embedded in the fin at the second side of the gate stack. The epitaxial structures of the first and second source or drain structures have a vertical trench centered therein. The first and second source or drain structures include silicon and a Group V dopant impurity.

  • Patent number: 12224337
    Abstract: III-N e-mode high electron mobility transistors (HEMTs) including a dopant diffusion spacer between an impurity-doped III-N material layer and a III-N polarization layer of the HEMT material stack. The spacer may be a substantially undoped III-N material, such as GaN. With the diffusion spacer, P-type impurities within the pGaN are setback from the polarization layer sufficiently to avoid significant levels of P-type impurities from entering the III-N material interface where the 2DEG resides. With the diffusion spacer, clustering of impurities near the 2DEG may be avoided and a III-N e-mode HEMT may achieve higher drive currents.

  • Patent number: 11815352
    Abstract: A downhole borehole imaging tool and methods for determining a borehole size includes a magnetoresistive system and a hub moveably coupled to a fixed tool string. The hub includes a magnet. The magnetoresistive system includes magnetoresistive sensors disposed within the fixed tool string and segregated from the magnet. During operation, a routine scan of all sensors measures, for example, the output voltage V, angle ? of magnetic field, and temperature. Measurements from each sensor may then be characterized to account for temperature and input voltages variation of the sensors. The most accurate measurement can be used to derive the position of the hub 44 using the previous baseline parameters stored in the tool.

  • Patent number: 11813167
    Abstract: A femoral implant for articulation with a patella or a patellar implant includes a body having an articular surface defining a trochlear groove. The trochlear groove is defined by a first trochlear radius at a first location along the trochlear groove and by a second trochlear radius at a second location along the trochlear groove, the first radius being different than the second radius. The configuration of the trochlear groove is such that it narrows as a patella or patellar implant moves from an extension configuration to a flexion configuration. A kit includes the femoral implant along with a patellar implant. A method of trialing involves use of the femoral implant or kit to ensure a smooth transition of the patella or the patellar implant from the femoral component to the adjacent bone.

  • Patent number: 10098747
    Abstract: Disclosed herein are knee replacement systems for replacing the articular surface of a distal femur. The systems include one or more unicompartmental components, namely patellofemoral, lateral condylar and medial condylar components. The components are configured such that when engaged to the femur the peripheries thereof do not cross specific locations and/or regions of the femur, namely the intercondylar notch and condylopatellar notch. The patellofemoral components described herein preferably have an extension portion extending posteriorly from a posterior periphery thereof towards an intercondylar notch of the femur without contacting the intercondylar notch of the femur when the patellofemoral component is engaged to the femur. The extension portion preferably extends posteriorly from a posterior periphery of the patellofemoral component towards the condylopatellar notch of the femur without contacting the notch.

  • Patent number: 10030505
    Abstract: A method for determining a depth related parameter of an instrument in a wellbore includes measuring movement of the instrument along the wellbore using a wheel sensor urged into contact with a wall of the wellbore. Movement of an instrument conveyance is measured proximate the surface. Measurements from the wheel sensor are calibrated using measurements of movement of the instrument conveyance. The depth related parameter of the instrument is determined using the calibrated wheel sensor measurements.
