Claim Text:
1. An optoelectronic semiconductor chip comprising: an optoelectronic structure; a carrier for the optoelectronic structure comprising: an electrically insulating carrier element having a mounting side and is a planar area at a side facing the optoelectronic structure, wherein the planar area extends along a whole lateral extent of the optoelectronic structure and has neither steps nor projections in a lateral and vertical direction; and on a side of the electrically insulating carrier element facing away from the optoelectronic structure, an auxiliary carrier is mechanically fixedly attached to the electrically insulating carrier element; at least one electrically conductive n-type wiring layer arranged at the mounting side; a structured, electrically conductive contact layer, which has at least one p-side contact region and at least one n-side contact region and which is arranged at a side of the n-type wiring layer facing away from the electrically insulating carrier element so that the contact regions terminate flush with a top side of the carrier; at least one insulation region which electrically insulates the p-side contact region from the n-side contact region; at least one electrically insulating spacer layer arranged at a side of the n-type wiring layer facing away from the electrically insulating carrier element in a vertical direction, extending perpendicular to the top side, between the p-side contact region and the n-type wiring layer, wherein the n-side contact region and the n-type wiring layer electrically conductively connected to one another; the p-side contact region and the spacer layer completely border the n-side contact region in a lateral direction; the optoelectronic structure comprises contact elements electrically connected to the optoelectronic structure, the contact elements being different components from the contact regions and terminating flush with a backside of the optoelectronic structure; the optoelectronic structure is disposed conclusively and mechanically fixedly with its backside on the top side of the carrier; the contact elements are disposed on the contact regions of the carrier and electrically connected to the contact regions; and in the vertical direction, the contact elements and the contact regions are not formed from one single piece.
