LIGHT EMITTING DEVICE AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A light emitting device and a method for fabricating the same are provided to improve optical power and light uniformity by using a graphite contact layer for extending current flow in a horizontal direction. CONSTITUTION: A light emitting structure (20) is formed on a semiconductor growth substrate (10). The light emitting structure includes a first conductive semiconductor layer (21), an active layer (22), and a second conductive semiconductor layer (23). A graphite layer is formed in at least one surface of the light emitting structure. An oxygen plasma process is performed on the graphite layer to form a graphite contact layer (31). A first and a second electrode (21a,23a) which are electrically connected to the first and the second conductive semiconductor layer respectively are formed.
