Abstract:
A light emitting diode having improved light efficiency and enhanced reflectivity of a device by forming an insulating reflective part on a reflective electrode formed on the upper surface of a mesa. A mesa exposing part is formed on the outer periphery and/or in the interior region of the reflective electrode to expose a predetermined area of the upper surface of the mesa such that reflection at the mesa exposing part is performed by the insulating reflective part.

Claim (Index 18):
A light emitting diode comprising:\n a lower semiconductor layer; an upper semiconductor layer disposed on the lower semiconductor layer; an active layer interposed between the lower semiconductor layer and the upper semiconductor layer; a first opening formed through the upper semiconductor layer and the active layer to expose the lower semiconductor layer; a reflective insulation layer covering the upper semiconductor layer and the lower semiconductor layer and having a second opening formed inside the first opening to define a first contact region of the lower semiconductor layer; and a first electrode layer disposed on the reflective insulation layer and connected to the first contact region of the lower semiconductor layer, wherein: the reflective insulation layer has a stacked structure in which a first material layer having a first index of refraction and a second material layer having a second index of refraction are alternately stacked one above another; the first contact region is placed on a bottom surface of the first opening; and an angle \u0398 of a sidewall of the second opening with respect to the lower semiconductor layer satisfies the following Equation 1, in which h indicates a thickness of the reflective insulation layer and a indicates a length of the bottom surface of the first opening from the first contact region to the sidewall of the first opening:\n tan \u22121 (2 h/a )\u2264\u0398\u226455\u00b0. \u2003\u2003<Equation 1>
