Abstract
The present invention provides a semiconductor light emitting device including a substrate, a first semiconductor layer, a first cladding layer, an active layer, a second cladding layer and a second semiconductor layer, and a manufacturing method. The first semiconductor layer may be an n-type semiconductor including a III-V semiconductor or a II-VI semiconductor. The second semiconductor layer may be a p-type semiconductor including a I-VII semiconductor. The semiconductor light emitting device may further include a third cladding layer between the active layer and the second cladding layer, the third cladding layer including a III-V semiconductor or a II-VI semiconductor. Therefore, by providing the hybrid type semiconductor light emitting device and the manufacturing method thereof, the luminous efficiency limit of the p-type semiconductor can be overcome.
