Abstract:
In an embodiment, an optoelectronic semiconductor component includes a first semiconductor layer of a first conductivity type, a second semiconductor layer of a second conductivity type, wherein a respective semiconductor material of the first and second semiconductor layers are each a compound semiconductor material including a first, a second and a third composition element, and a second contact region configured to electrically contact the second semiconductor layer, wherein the first semiconductor layer is patterned and arranged over the second semiconductor layer, wherein the second contact region is arranged between patterned regions of the first semiconductor layer, wherein the second contact region comprises a second metallic contact layer and a semiconductor contact layer between the second metallic contact layer and the second semiconductor layer, wherein a semiconductor material of the semiconductor contact layer includes the first, second and third composition elements, and wherein a concentration of the first and second composition elements varies from a position on a side of the second semiconductor layer to a position on a side of the second metallic contact layer.
