  • Patent number: 11348906
    Abstract: An optoelectronic device comprises a phosphor plate, an optoelectronic chip comprising a layer stack of a first optoelectronic semiconductor layer and a second optoelectronic semiconductor layer, a first electrode, and a second electrode. The optoelectronic chip is attached to the phosphor plate, so that the second optoelectronic semiconductor layer is arranged between the phosphor plate and the first optoelectronic semiconductor layer. The first electrode and the second electrode are arranged on a first main surface of the first optoelectronic semiconductor layer on a side remote from the phosphor plate. The second electrode directly contacts the first optoelectronic semiconductor layer.

  • Patent number: 10854788
    Abstract: An optoelectronic component and a method for producing an optoelectronic component are disclosed. In an embodiment a method includes attaching a plurality of optoelectronic semiconductor chips on predetermined locations of an intermediate film, providing a cavity film with a plurality of separated openings, attaching the cavity film to the intermediate film such that each optoelectronic semiconductor chip is associated with a respective opening, wherein the cavity film is thicker than the optoelectronic semiconductor chips such that the cavity film exceeds the optoelectronic semiconductor chips in a direction away from the intermediate film, filling a casting material in each of the openings such that the optoelectronic semiconductor chips are casted with the casting material and removing the intermediate film.
