    摘要: Light emitting diodes include a substrate having first and second opposing faces and that is transparent to optical radiation in a predetermined wavelength range and that is patterned to define, in cross-section, a plurality of pedestals that extend into the substrate from the first face towards the second face. A diode region on the second face is configured to emit light in the predetermined wavelength range, into the substrate upon application of voltage across the diode region. A mounting support on the diode region, opposite the substrate is configured to support the diode region, such that the light that is emitted from the diode region into the substrate, is emitted from the first face upon application of voltage across the diode region. A reflector is provided between the mounting support and the diode region, that is configured to reflect light that is emitted from the diode region back into the diode region, through the substrate that is transparent to optical radiation in the predetermined wavelength range and from the plurality of pedestals, upon application of voltage across the diode region. A layer of Indium Tin Oxide (ITO) is provided between the reflector and the diode region.

    摘要: A method and resulting structures are disclosed for fabricating a high efficiency high extraction light emitting diode suitable for packaging. The method includes the steps of adding a light emitting active portion of wide-bandgap semiconductor material to a conductive silicon carbide substrate, joining the added active portion to a conductive sub-mounting structure, and removing a portion of the silicon carbide substrate opposite the added active portion to thereby reduce the overall thickness of the joined substrate, active portion and sub-mounting structure. The resulting the sub-mounting structure can be joined to a lead frame with the active portion positioned between the silicon carbide substrate and the sub-mounting structure to thereby use the sub-mounting structure to separate the active portion from the lead frame and avoid undesired electrical contact between the active portion and the lead frame.

    摘要: The compass system of the present invention utilizes an improved calibration routine in which a processing circuit of the compass recalibrates the compass each time three data points are obtained from a magnetic field sensor that meet predetermined criteria. One such criterion is that the three data points define corners of a triangle that is substantially non-obtuse. When three data points have been obtained that define a triangle meeting this criterion, the processing circuit calculates a center point for a circle upon which all three data points lie by solving the equation x2+y2+Ax+By+C=0 for A, B, and C, using the coordinate values (x,y) for the three data points and defining the center point as (−A/2, −B/2).

    摘要: Processing a semiconductor wafer can include forming a plurality of Light Emitting Devices (LED) on a semiconductor wafer having a first thickness. The plurality of LEDs on the wafer are brought into contact with a surface of a carrier to couple the wafer to the carrier. The first thickness of the wafer is reduced to a second thickness that is less than the first thickness by processing the backside of the wafer. The carrier is separated from the plurality of LEDs on the wafer and the wafer is cut to separate the plurality of LEDs from one another. Related devices are also disclosed.
