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.

摘要： An island submount used for carrying at least one light-emitting element having at least one electrical contact. The island submount includes a substrate, at least one island structure having a top surface and an inclined surface, and a conductive layer. The island structure is located on the substrate and corresponds to the electrical contact. The conductive layer is formed on the surface of the island structure and at least covers the top surface, so as to be electrically connected with the electrical contact. The island submount is capable of enhancing the light extraction efficiency of the light-emitting element, and avoids the energy loss due to re-absorption when the light emerging from below the light-emitting element is reflected back to the light-emitting element.
