    摘要： A semiconductor device having light-emitting diodes (LEDs) formed on a concave textured substrate is provided. A substrate is patterned and etched to form recesses. A separation layer is formed along the bottom of the recesses. An LED structure is formed along the sidewalls and, optionally, along the surface of the substrate between adjacent recesses. In these embodiments, the surface area of the LED structure is increased as compared to a planar surface. In another embodiment, the LED structure is formed within the recesses such that the bottom contact layer is non-conformal to the topology of the recesses. In these embodiments, the recesses in a silicon substrate result in a cubic structure in the bottom contact layer, such as an n-GaN layer, which has a non-polar characteristic and exhibits higher external quantum efficiency.

    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.
