SUBSTRATE FOR SEMICONDUCTOR LIGHT EMITTING DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A substrate for a semiconductor light emitting device and a manufacturing method thereof are provided to supply a protrusion which has a depression side and an extrusion side, in a growing top side, thereby providing a substrate which has a protrusion with a scattering side. CONSTITUTION: A substrate(10) for a semiconductor light emitting device comprises a top side and a protrusion(11a). A semiconductor layer(20) is grown on the top side. The protrusion is formed on the top side and has a depression side and an extrusion side. The depression sides and the extrusion sides are alternatively formed on the protrusion.
