    Abstract: Disclosed are multi-junction light emitting diode (LED) formed by using eutectic bonding and method of manufacturing the multi-junction LED. The multi-junction LED is formed by stacking a separately formed light emitting structure on another light emitting structure by using eutectic bonding. Since separately grown light emitting structure is stacked on the light emitting structure using the eutectic metal alloy bonding, it is possible to prevent crystal defects occurring between the light emitting structures when sequentially grown. Further, since the eutectic metal alloy can be formed in various patterns, it is possible to control and optimize adhesive strength, transmittance of the light generated in the upper light emitting structure, and resistance.
