Abstract:
1. An optoelectronic semiconductor chip comprising: a semiconductor layer sequence having an active layer provided for generating radiation, the active layer between a layer of a first conductivity type and a layer of a second conductivity type, wherein the layer of the first conductivity type is adjacent to a front side of the semiconductor layer sequence, wherein the semiconductor layer sequence contains at least one cutout extending from a rear side of the semiconductor layer sequence through the active layer to the layer of the first conductivity type, the rear side opposite the front side, wherein the layer of the first conductivity type is electrically connected through the cutout by a first electrical connection layer that covers the rear side of the semiconductor layer sequence at least in places, and wherein the optoelectronic semiconductor chip contains a junction layer adjacent the cutout, the junction layer comprising a material composition comprising material of the layer of the first conductivity type and material of the first electrical connection layer.
