Optoelectronic semiconductor component, and method for producing at least one optoelectronic semiconductor component

An optoelectronic semiconductor component comprising

• a semiconductor layer stack comprising
• a first semiconductor region,
• a second semiconductor region, and
• an active zone which is arranged between the first and second semiconductor regions, wherein the second semiconductor region comprises a first semiconductor layer and a second semiconductor layer, and the second semiconductor layer is arranged on a side of the first semiconductor layer facing away from the active zone,
• at least one depression which extends from a first main surface of the semiconductor layer stack through the first semiconductor region and the active zone and ends at the second semiconductor layer,
• a first contact structure for electrically contacting the first semiconductor region, said first contact structure being arranged at least in some areas at the first main surface,
• a second contact structure for electrically contacting the second semiconductor region, said second contact structure being arranged in some areas at the first main surface and in the at least one depression,
• wherein the first semiconductor layer comprises a first compound semiconductor material and the second semiconductor layer comprises a second compound semiconductor material, and the first compound semiconductor material has a higher aluminum content than the second compound semiconductor material.
