    摘要: This invention discloses a GaN semiconductor device comprising a substrate; a metal-rich nitride compound thin film on the substrate; a buffer layer formed on the metal-rich nitride compound thin film, and a semiconductor stack layer on the buffer layer wherein the metal-dominated nitride compound thin film covers a partial upper surface of the substrate. Because metal-rich nitride compound is amorphous, the epitaxial growth direction of the buffer layer grows upwards in the beginning and then turns laterally, and the epitaxy defects of the buffer layer also bend with the epitaxial growth direction of the buffer layer. Therefore, the probability of the epitaxial defects extending to the semiconductor stack layer is reduced and the reliability of the GaN semiconductor device is improved.

    摘要: A light emitting diode (LED) package includes a carrier, an LED chip, an encapsulant, a plurality of phosphor particles, and a plurality of anti-humidity particles. The LED chip is disposed on and electrically connected to the carrier. The encapsulant encapsulates the LED chip. The phosphor particles and the anti-humidity particles are distributed within the encapsulant. A first light emitted from the LED chip excites the phosphor particles to emit a second light. Some of the anti-humidity particles are adhered onto a surface of the phosphor particles, while the other anti-humidity particles are not adhered onto the surface of the phosphor particles. The anti-humidity particles absorb H2O so as to avoid H2O from being reacted with the phosphor particles. The LED package of the present application has favorable water resistance.
