Abstract:
A method of fabricating a semiconductor light emitting device includes forming a first conductivity type semiconductor layer, forming an active layer by alternately forming a plurality of quantum well layers and a plurality of quantum barrier layers on the first conductivity type semiconductor layer, and forming a second conductivity type semiconductor layer on the active layer. The plurality of quantum barrier layers include at least one first quantum barrier layer adjacent to the first conductivity type semiconductor layer and at least one second quantum barrier layer adjacent to the second conductivity type semiconductor layer. The forming of the active layer includes allowing the at least one first quantum barrier layer to be grown at a first temperature and allowing the at least one second quantum barrier layer to be grown at a second temperature lower than the first temperature.

Abstract:
A method for manufacturing a semiconductor light emitting device is provided. The method includes forming a light emitting structure by sequentially growing a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer on a semiconductor growth substrate A support unit is disposed on the second conductivity-type semiconductor layer, so as to be combined with the light emitting structure. The semiconductor growth substrate is separated from the light emitting structure. An interface between the semiconductor growth substrate and a remaining light emitting structure is wet-etched such that the light emitting structure remaining on the separated semiconductor growth substrate is separated therefrom. The semiconductor growth substrate is cleaned.
