Abstract: An optoelectronic device may include an optoelectronic semiconductor chip that is configured to emit electromagnetic radiation. The chip may include a first semiconductor layer, a second semiconductor layer, first and second current spreading structures, and a plurality of electrical contact elements. The first current spreading layer may be arranged on a side of the second semiconductor layer facing away from the first semiconductor layer. The plurality of electrical contact elements may electrically connect the first semiconductor layer to the first current spreading layer. The second current spreading layer may be electrically connected to the second semiconductor layer. The second current spreading layer may be arranged between the first current spreading layer and the second semiconductor layer where an insulating layer insulates a first electrical contact element and a second electrical contact element from the second current spreading layer.

Abstract: An optoelectronic semiconductor component may have a semiconductor body comprising a first region of an n-type conductivity, a second region of a p-type conductivity, an active region capable of generating electromagnetic radiation, a marker layer, a plurality of emission regions and a plurality of recesses. The active region is disposed between the first region and the second region in a plane parallel to the main extension plane of the semiconductor body. The recesses delimit the emission regions in lateral direction. Starting from the side of the first region facing away from the active region, the recesses extend transversely to the main plane of the semiconductor body in the direction of the second region and adjoin the marker layer or penetrate the marker layer completely. The recesses are formed only in the first region or the recesses extend into the second region and completely penetrate the active region.
