Abstract
An optoelectronic semiconductor device may include a first semiconductor layer, a second semiconductor layer, first and second current spreading structures, and an insulating intermediate layer. The second semiconductor layer may be arranged over a substrate. The first semiconductor layer may be arranged between the second semiconductor layer and the substrate. The first current spreading structure may be electrically connected to the first semiconductor layer, and the second current spreading structure electrically may be connected to the second semiconductor layer. The insulating intermediate layer may include a dielectric mirror and may be arranged between the second current spreading structure and the second semiconductor layer. The current spreading structures may overlap one another in a plane perpendicular to a main surface of the substrate. The first current spreading structure may be arranged at a larger distance from the first semiconductor layer than the second current spreading structure.
