  • Patent number: 11715815
    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.

  • Publication number: 20210351332
    Abstract: In one embodiment, the optoelectronic semiconductor device has a semiconductor layer sequence arranged to generate red or orange light. A plurality of electrical through-connections extend through the semiconductor layer sequence. A first main side of the semiconductor layer sequence is electrically contacted by a first electrical contact structure. A second electrical contact structure is located on the first main side. The second contact structure electrically connects the through-connections to one another. The second contact structure is embedded in the first contact structure.

  • Publication number: 20210296549
    Abstract: The optoelectronic semiconductor chip may include a semiconductor layer sequence having an active zone for generating radiation between a first region and a second region. The second region is electrically contacted via electrical through-connections that are electrically connected via metallic contact strips. The first region is electrically contacted via a metallic contact layer. An electrical insulation layer is located between the contact strips and the contact layer. The contact layer and the contact strips are located on a back side of the first region. The through-connections extend from the contact strips through the first region and through the active zone into the second region. The contact strips lie at least predominantly between the back side and the contact layer.
