Abstract: Embodiments include a Schottky barrier diode (SBD) structure and method of forming the same, the SBD structure including a current blockage feature to inhibit current from leaking at an interface with a shallow trench isolation regions surrounding an anode region of the SBD structure.

Abstract: The present disclosure is directed to a method of manufacturing one or more needles of a probe card by refining and processing a conductive body that extends from the probe card to form a respective tip at the end of the respective conductive body. Forming the respective tip of a respective needle includes removing respective portions from the end of the conductive body by flowing an electrolytic fluid between a conductive pattern structure and an end of the respective conductive body. Removing the respective portions with the flow of the electrons may be performed in multiple successive steps to form various needles with various sizes, shapes, and profiles (e.g., cylindrical, rectangular, triangular, trapezoidal, etc.).

Abstract: A premixer assembly for a combustor includes: at least one ring of premixers, each premixer having a central axis, an annular peripheral wall surrounding a centerbody, and at least one swirler disposed between the centerbody and the peripheral wall, wherein the peripheral wall defines an inlet area of the premixer; and a lip extending forward along the central axis from the peripheral wall, the lip extending at an oblique angle to the axis of symmetry.

Abstract: An apparatus and method fabricating a deflector-flare cone for a combustor is provided. The combustor includes an air swirler annular about a centerline axis of the combustor wherein the swirler includes an annular exit downstream of the swirler. The deflector-flare cone includes a single annular body including an engagement end configured to support the deflector-flare cone, an annular divergent portion extending downstream from the engagement end. The annular divergent portion includes a radially outer annular deflector portion and a radially inner annular flare cone portion that are separated by an annular gap extending between the deflector portion and the flare cone portion. The deflector-flare cone includes a plurality of cooling passages extending through the single annular body of the deflector-flare cone. The plurality of cooling passages are spaced circumferentially about the centerline axis and are configured to be coupled in flow communication with a cooling fluid source.

Abstract: A swirler includes a tubular body having a row of secondary radial swirl vanes. A tubular ferrule adjoins the body at the secondary vanes, and includes a row of primary swirl vanes. The primary vanes are disposed axially obliquely to the secondary vanes, with a common annular inlet facing radially outwardly for swirling air radially inwardly therefrom with axial momentum into the tubular body.
