Abstract: A mount for a semiconductor device includes a carrier, at least two metal leads disposed on a bottom surface of the carrier, and a cavity extending through a thickness of the carrier to expose a portion of the top surfaces of the metal leads. A semiconductor light emitting device is positioned in the cavity and is electrically and physically connected to the metal leads. The carrier may be, for example, silicon, and the leads may be multilayer structures, for example a thin gold layer connected to a thick copper layer.

Abstract: A light emitting diode (LED) package includes a support, an LED die mounted on the support, a reflector around the LED die, and a lens over the LED die. The reflector has an angled reflective surface that limits the light emission angle from the LED package. The reflector is a part of the lens or the support.

Abstract: A device structure includes a III-nitride wurtzite semiconductor light emitting region disposed between a p-type region and an n-type region. A bonded interface is disposed between two surfaces, one of the surfaces being a surface of the device structure. The bonded interface facilitates an orientation of the wurtzite c-axis in the light emitting region that confines carriers in the light emitting region, potentially increasing efficiency at high current density.

Abstract: A composite semiconductor light-emitting display array. Light is emitted and observed through a light-transmissive planar array of LED devices formed in a monolithic transparent single crystal such as GaP. Light is generated at the back of the single crystal, but is observed through the front of the crystal. The crystal with its array of LED's is directly interconnected with a monolithic circuit having circuit elements for energizing the LED devices. The result is a composite sandwich structure with interconnections sandwiched between the LED array and the integrated circuit.
