  • Publication number: 20120214266
    Abstract: A manufacturing method of nitride semiconductor light emitting elements, which can reliably form a mechanically stable wiring electrode leading from a light emitting element surface. A structure protective sacrifice layer is formed around a first electrode layer on a device structure layer beforehand, and after separation of the device structure layer into respective portions for the light emitting elements, the resultant is stuck to a support substrate. Subsequently, forward tapered grooves reaching the structure protective sacrifice layer are formed, and the inverse tapered portion formed outward of the forward tapered groove is lifted off in a lift-off step. Thus, an insulating layer is formed on the forward tapered side walls of the light emitting element, and a wiring electrode layer electrically connected to the second electrode layer on the principal surface of the light emitting element is formed on the insulating layer.

    Abstract: A light emitting diode package for one or more light emitting diodes mounted on a substrate. A frame is disposed on at least a portion of the substrate and substantially surrounds, but does not contact, the light emitting diode. The frame is substantially transparent to light emitted from the light emitting diode and includes one or more first wavelength converting materials. The wavelength converting materials, which may be one or more phosphors, convert at least a portion of light emitted at the emission wavelength to different wavelength. A cover covers the light emitting diode within the frame. The cover layer includes one or more second wavelength converting materials differing from the first one or more wavelength converting materials in wavelength converting material concentration or in converted light wavelength or in combinations of wavelength converting materials.
