Claim Text:
1. An optoelectronic semiconductor chip comprising: a carrier; and a semiconductor body disposed on the carrier, the semiconductor body comprising a semiconductor layer sequence having an active region configured to generate or receive radiation, the active region being arranged between a first semiconductor layer and a second semiconductor layer, wherein the semiconductor chip has a recess extending from a first main surface of the carrier, through the carrier, the second semiconductor layer and the active region into the first semiconductor layer, the first main surface facing away from the semiconductor body, wherein a first contact is arranged on the first main surface of the carrier, the first contact being connected to the first semiconductor layer in the recess, and wherein the recess comprises a first region that does not completely extend through the carrier, wherein a cross section of the recess increases in the first region toward the first main surface of the carrier, wherein a cross section of the recess towards a second main surface of the carrier is identical or substantially identical to a cross section of the recess at a level of the active region, the second main surface facing the semiconductor body, wherein the recess comprises a second region arranged on a side of the first region that faces the semiconductor body, wherein the second region partially extends through the carrier, and wherein a cross section of the second region on a side facing toward the first region is identical or substantially identical to the cross section of the recess at the level of the active region.
