SEMICONDUCTOR LIGHT EMITTING DEVICE WHICH INCLUDES AN AIR GAP, CAPABLE OF IMPROVING OPTICAL EXTRACTION EFFICIENCY BY IMPROVING SCATTERING DIFFRACTION EFFECT, AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A semiconductor light emitting device and a manufacturing method thereof are provided to form an air gap through a seed layer on a substrate which includes a concavo-convex part.;CONSTITUTION: A substrate includes a plurality of concavo-convex parts. A seed layer is formed on the side and the upper part of the concavo-convex part through a lateral growth process. A semiconductor layer is formed on the seed layer. The semiconductor layer is formed into a cantilever form. An air gap(140) is formed in the lower part of the semiconductor layer.;COPYRIGHT KIPO 2011
