High output light emitting diode and method for fabricating the same

Abstract

A high output light emitting diode (LED) and a method for fabricating the LED is disclosed. The LED includes a sidewall or surface that is inclined. A reflective film is formed on the inclined sidewall or surface to allow light to reflect from the reflective film and to emit the light upward or in a favorable direction with respect to the device, thereby being configured and enabled to improve a light output of the LED and dispense with an additional passivation process.
