摘要： The present invention relates to a method for manufacturing a light-emitting diode, in which the tilt angle of a convex-concave portion formed in a semiconductor layer are adjusted through the variation of a dry-etching condition using the difference between etching speeds (etching rates) of a nanostructure and a semiconductor layer during dry etching, to thereby improve light extraction efficiency. The present invention also relates to a light-emitting diode manufactured by the method. The present invention is a method for manufacturing a light-emitting diode in which an active layer and a second semiconductor layer are sequentially formed on a first semiconductor layer, wherein the method comprises: a step of coating a nanostructure onto the second semiconductor layer; and a step of dry-etching the nanostructure together with the second semiconductor layer using the nanostructure as a mask, to thus form a convex-concave portion in the second semiconductor layer. The nanostructure uses a material which enables easier dry-etching than the material of the second semiconductor layer, and a dry-etching condition is set in consideration of the difference in the etching rate between the second semiconductor layer and the nanostructure, so as to adjust the tilt angle of the side surface of the convex-concave portion formed in the second semiconductor layer.

摘要： Disclosed is a light-emitting diode package, comprising high-output and high-efficiency light-emitting diodes in which the efficiency droop phenomenon, which occurs in response to the injection of high current, is prevented to achieve improved light emission efficiency. The light-emitting diode package is configured such that the surface of a base on which the light-emitting diodes are to be attached is curved by means of a device or a specific structure, and the light-emitting diodes are die-bonded to the curved surface so as to enable the light-emitting diodes to be bent by the curvature of the curved surface. Here, stresses are applied to the light-emitting diodes, thus causing changes in a band structure of a quantum well layer. In the thus-produced light-emitting diode package, efficiency droop, which occurs in response to the injection of high current, is reduced to achieve the high output and high efficiency of the package.
