    摘要: A fabricating method of nitride semiconductor substrate is provided. First, a first substrate including a first base material, a nitride semiconductor template layer stacked on the first base material, and a first dielectric layer stacked on the nitride semiconductor template layer is provided. Then, the first dielectric layer and the nitride semiconductor template layer are patterned, and a second substrate including a second base material and a second dielectric layer stacked on the second base material is provided. Next, the nitride semiconductor template layer and the first dielectric layer of the first substrate are transferred onto the second dielectric layer of the second substrate through bonding and transferring processes, and then a nitride semiconductor thick film is grown from the nitride semiconductor template layer through an epitaxy process. After that, the nitride semiconductor thick film and the second substrate are separated.

    摘要: The present invention relates to a method of forming a nitride semiconductor substrate. This method includes steps of providing a substrate and then forming an epitaxy layer on the substrate. A patterned mask layer is formed on the epitaxy layer, wherein the patterned mask layer exposes a portion of the epitaxy layer. Next, an oxidation process is performed to oxidize the exposed epitaxy layer so as to form a plurality of dislocation blocking structures. The patterned mask layer is then removed. Further, a nitride semiconductor layer is formed on the epitaxy layer having the dislocation blocking structures.

    摘要: There is provided a method of forming a nitride semiconductor layer, including the steps of firstly providing a substrate on which a patterned epitaxy layer with a pier structure is formed. A protective layer is then formed on the patterned epitaxy layer, exposing a top surface of the pier structure. Next, a nitride semiconductor layer is formed over the patterned epitaxy layer connected to the nitride semiconductor layer through the pier structure, wherein the nitride semiconductor layer, the pier structure, and the patterned epitaxy layer together form a space exposing a bottom surface of the nitride semiconductor layer. Thereafter, a weakening process is performed to remove a portion of the bottom surface of the nitride semiconductor layer and to weaken a connection point between the top surface of the pier structure and the nitride semiconductor layer. Finally, the substrate is separated from the nitride semiconductor layer through the connection point.
