Patent number: 12342611Abstract: 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.Type: GrantFiled: January 29, 2024Date of Patent: June 24, 2025Assignee: Intel CorporationInventors: Ryan Keech, Nicholas Minutillo, Anand Murthy, Aaron Budrevich, Peter Wells

Patent number: 12224337Abstract: 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.Type: GrantFiled: December 23, 2020Date of Patent: February 11, 2025Assignee: Intel CorporationInventors: Michael Beumer, Robert Ehlert, Nicholas Minutillo, Michael Robinson, Patrick Wallace, Peter Wells

Patent number: 11815352Abstract: 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.Type: GrantFiled: March 30, 2021Date of Patent: November 14, 2023Assignee: Schlumberger Technology CorporationInventors: Julien Toniolo, Alan J.

Patent number: 11813167Abstract: 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.Type: GrantFiled: May 15, 2018Date of Patent: November 14, 2023Assignee: Howmedica Osteonics Corp.Inventors: Peter Wellings, Sandeep K.
