Efficiency enhanced semiconductor device using moth-eye structure and Its manufacturing method

摘要

PURPOSE: A semiconductor device with high efficiency using a moth-eye structure and a manufacturing method thereof are provided to improve luminous efficiency by forming the moth-eye structure in a light receiving area. CONSTITUTION: A light emitting structure is comprised of a first semiconductor layer, an active layer, and a semiconductor layer. A part of the first semiconductor layer with a preset width is exposed by etching a part of the semiconductor layer and the active layer. A first electrode(306) is formed on the exposed area of the first semiconductor layer. A second electrode(307) is formed on the second semiconductor layer. A nano sized moth-eye structure(308) is formed on the lower side of the first semiconductor layer.
