LIGHT EMITTING DEVICE, METHOD OF MANUFACTURING THE SAME, LIGHT EMITTING DEVICE PACKAGE AND LIGHTING SYSTEM |
摘要 |
A light emitting device includes an active layer formed between first and second semiconductor layers. The first semiconductor layer includes a first surface facing the active layer, a second surface opposing the first surface, and a side surface that includes a stepped portion. The stepped portion causes the side surface to extend beyond one of the first surface or second surface of the first semiconductor layer. A light emitting device may also be formed with a buffer layer that includes a stepped portion, and a light emitting device package and system may be formed from the light emitting devices.
