PROBLEM TO BE SOLVED: To provide a manufacturing method of a GaN-based semiconductor light-emitting element that can inhibit lowering in a light extraction efficiency by etching and to provide a semiconductor light-emitting element manufactured by the method.SOLUTION: The semiconductor light-emitting element manufacturing method comprises the steps of: forming a plurality of island-shaped mask layers 150 of a top face of a first upper clad layer 14A; selectively forming a second upper clad layer 14B on the top face of the first upper clad layer 14A at a non-forming region of the plurality of island-shaped mask layers 150 by crystal growth; and filling each of the mask layers 150 by thickly forming the second upper clad layer 14B.
Abstract:
PROBLEM TO BE SOLVED: To provide a light emitting diode of significantly high light emitting efficiency that can be manufactured by one-time epitaxial growth at a low cost, and a manufacturing method thereof. SOLUTION: In a recess 11a formed on one main surface of a sapphire substrate 11, growth in a lateral direction is performed from a GaN layer 12, after burying the recess 11a by making the GaN layer 12 grow after passing through a state of a triangular cross section shape with its bottom face as a base. A light emitting diode structure is formed on the GaN layer 12 by growing a GaN based semiconductor layer including an active layer on the GaN layer 12. By using the GaN based light emitting diode, a light emitting diode backlight, etc. is manufactured. COPYRIGHT: (C)2007,JPO&INPIT
