    摘要: A semiconductor structure includes a substrate and a conductive carrier-tunneling layer over and contacting the substrate. The conductive carrier-tunneling layer includes first group-III nitride (III-nitride) layers having a first bandgap, wherein the first III-nitride layers have a thickness less than about 5 nm; and second III-nitride layers having a second bandgap lower than the first bandgap, wherein the first III-nitride layers and the second III-nitride layers are stacked in an alternating pattern. The semiconductor structure is free from a III-nitride layer between the substrate and the conductive carrier-tunneling layer. The semiconductor structure further includes an active layer over the conductive carrier-tunneling layer.

    摘要: A light-emitting diode (LED) device is provided. The LED device is formed by forming an LED structure on a first substrate. A portion of the first substrate is converted to a porous layer, and a conductive substrate is formed over the LED structure on an opposing surface from the first substrate. The first substrate is detached from the LED structure along the porous layer and any remaining materials are removed from the LED structure.

    摘要: A light-emitting diode (LED) device is provided. The LED device has a substrate and an LED structure overlying the substrate. Embedded elements are embedded within one or more layers of the LED structure. In an embodiment, the embedded elements include a dielectric material extending through the LED structure such that the embedded elements are surrounded by the LED structure. In another embodiment, the embedded elements only extend through an upper layer of the LED structure, or alternatively, partially through the upper layer of the LED structure. Another conductive layer may be formed over the upper layer of the LED structure and the embedded elements.

    摘要: A light-emitting diode (LED) device is provided. The LED device has a substrate, a reflective structure over the substrate, and an LED structure over the reflective structure. The reflective structure is formed of non-metallic materials. In one embodiment, the reflective structure is formed of alternating layers of different non-metallic materials having different refractive indices. In another embodiment, the reflective structure is formed of alternating layers of high-porosity silicon and low-porosity silicon. In yet another embodiment, the reflective structure is formed of silicon dioxide, which may allow the use of fewer layers. The reflective structure may be formed directly on the same substrate as the LED structure or formed on a separate substrate and then bonded to the LED structure.
