    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.

    摘要: A method of forming a light-emitting diode (LED) device and separating the LED device from a growth substrate is provided. The LED device is formed by forming an LED structure over a growth substrate. The method includes forming and patterning a mask layer on the growth substrate. A first contact layer is formed over the patterned mask layer with an air bridge between the first contact layer and the patterned mask layer. The first contact layer may be a contact layer of the LED structure. After the formation of the LED structure, the growth substrate is detached from the LED structure along the air bridge.

    摘要: A method for forming a semiconductor structure includes providing a semiconductor substrate including a first region and a second region; and forming a first and a second metal-oxide-semiconductor (MOS) device. The step of forming the first MOS device includes forming a first silicon germanium layer over the first region of the semiconductor substrate; forming a silicon layer over the first silicon germanium layer; forming a first gate dielectric layer over the silicon layer; and patterning the first gate dielectric layer to form a first gate dielectric. The step of forming the second MOS device includes forming a second silicon germanium layer over the second region of the semiconductor substrate; forming a second gate dielectric layer over the second silicon germanium layer with no substantially pure silicon layer therebetween; and patterning the second gate dielectric layer to form a second gate dielectric.
