Abstract: A manufacturing method of a solid state light emitting element is provided. A plurality of protrusion structures separated to each other are formed on a first substrate. A buffer layer is formed on the protrusion structures and fills the gaps between protrusion structures. An epitaxial growth layer is formed on the buffer layer to form a first semiconductor stacking structure. The first semiconductor stacking structure is inverted to a second substrate, so that the first semiconductor epitaxial layer and the second substrate are connected to form a second semiconductor stacking structure. The buffer layer is etched by a first etchant solution to form a third semiconductor stacking structure. A second etchant solution is used to permeate through the gaps between the protrusion structures, so that the protrusion structures are etched completely. The first substrate is removed from the third semiconductor stacking structure to form a fourth semiconductor stacking structure.

Abstract: A light emitting diode and a fabricating method thereof are provided. A first-type semiconductor layer, a light emitting layer and a second-type semiconductor layer with a first surface are sequentially formed a substrate. Next, the first surface is treated during a surface treatment process to form a current-blocking region which extends from the first surface to the light emitting layer to a depth of 1000 angstroms. Afterward, a first electrode is formed above the current-blocking region of the second-type semiconductor layer, and a second electrode is formed to electrically contact to the first-type semiconductor layer. Since the current-blocking region is formed with a determined depth within the second-type semiconductor layer, the light extraction efficiency of the light emitting diode may be increased.
