摘要: A semiconductor power device includes an engineered aluminum-nitride substrate structure, and method of fabricating the same are described. The engineered substrate structure is effectively integrated with a transition layer of AlN/AlGaN disposed thereon, a buffer layer disposed on the transition layer having a C—(Al)GaN/u-GaN multiple stacking layered structure, a channel layer, a barrier layer, and an optional SiNx interlayer together, to form a GaN-based semiconductor power device. The GaN buffer layer is capable of achieving sufficient thickness for higher performance. The engineered substrate structure has a core region made of an aluminum nitride (AlN) substrate, a single crystal silicon layer as top material layer thereof, and bonded together with an encapsulated multi-layered structure containing adhesive layers, thin film layers and the AlN substrate. Higher breakdown voltage and improved overall device quality with respect to epitaxy-induced bow, warp, and cracking issues are achieved by the semiconductor power device.

摘要: A light emitting diode having a transparent substrate and a method for manufacturing the same. The light emitting diode is formed by creating two semiconductor multilayers and bonding them. The first semiconductor multilayer is formed on a non-transparent substrate. The second semiconductor multilayer is created by forming an amorphous interface layer on a transparent substrate. The two semiconductor multilayers are bonded and the non-transparent substrate is removed, leaving a semiconductor multilayer with a transparent substrate.
