GROWTH SUBSTRATE, LIGHT EMITTING DIODE AND PACKAGE OF THEREOF

摘要

PURPOSE: A growth substrate, a light emitting device and a light emitting device package are provided to maximize the amount of optical extraction by forming a concavo-convex part at the side of a light emitting structure. CONSTITUTION: A first trench(14) has a first depth and is formed on a body(12). The first trench defines a single chip region. A non-growth layer(16) covers the front surface of the first trench. A light emitting structure is grown on a light emitting structure growth substrate which includes Al2O3, SiC, GaAs, or GaN. A first electrode layer is formed on the light emitting structure.
