摘要: A semiconductor device is provided, which includes a first semiconductor structure, a second semiconductor structure, and an active region. The first semiconductor structure includes a first dopant. The second semiconductor structure is located on the first semiconductor structure and includes a second dopant different from the first dopant. The active region includes a plurality of semiconductor pairs and located between the first semiconductor structure and the second semiconductor structure. Each semiconductor pair includes a barrier layer and a well layer and includes the first dopant. The active region does not include a nitrogen element. A doping concentration of the first dopant in the first semiconductor structure is higher than a doping concentration of the first dopant in the active region.

摘要: The present disclosure provides a semiconductor light-emitting device and a semiconductor light-emitting component. The semiconductor light-emitting device includes a substrate, a first semiconductor contact layer, a semiconductor light-emitting stack including an active layer, a first-conductivity-type contact structure, a second semiconductor contact layer, a second-conductivity-type contact structure and a first electrode pad. The first-conductivity-type contact structure is electrically connected to the first semiconductor contact layer. The second-conductivity-type contact structure is electrically connected to the second semiconductor contact layer. The first-conductivity-type contact structure has a first bottom surface and a first top surface, and the active layer has a second bottom surface and a second top surface. The first bottom surface is lower than the second bottom surface, and the first top surface is higher than the second top surface in a cross-sectional view of the semiconductor light-emitting device.
