    摘要: Provided is a light emitting diode (LED) manufactured by using a wafer bonding method and a method of manufacturing a LED by using a wafer bonding method. The wafer bonding method may include interposing a stress relaxation layer (33) formed of a metal between a semiconductor layer (20) and a bonding substrate (31). When the stress relaxation layer is used, stress between the bonding substrate and a growth substrate may be offset due to the flexibility of metal, and accordingly, bending or warpage of the bonding substrate may be reduced or prevented.

    摘要: A semiconductor structure including a first nitride semiconductor layer, a second nitride semiconductor layer, and a third layer between the first nitride semiconductor layer and the second nitride semiconductor layer. The first nitride semiconductor layer has a first gallium composition ratio, the second nitride semiconductor layer has a second gallium composition ratio different from the first metal composition ratio, and the third layer has a third gallium composition ratio greater than at least one of the first gallium composition ratio or the second gallium composition ratio. The structure may also include a fourth layer for reducing tensile stress or increasing compression stress experienced by at least the second nitride semiconductor layer.
