Abstract:
1. An optoelectronic semiconductor chip comprising: an active region; and a carrier arranged at an underside of the active region, wherein the active region has a main extension direction, wherein the active region has a core region comprising a first semiconductor material, wherein the active region has an active layer that covers the core region at least in directions transversely with respect to the main extension direction of the active region, wherein the active region has a cover layer comprising a second semiconductor material and overlying the active layer at least in the directions transversely with respect to the main extension direction of the active region, wherein the active region has traces of material removal at its top side facing away from the carrier, wherein the active region has a current spreading layer overlying the cover layer at least in the directions transversely with respect to the main extension direction, and wherein the current spreading layer, the cover layer and the active layer are removed at a side of the active region which faces away from the carrier and the core region of the active region is exposed.
