Claim 0:
1. A radiation emitting semiconductor chip comprising:
a radiation emitting surface comprising emitter regions separated from one another;
an epitaxial semiconductor layer sequence comprising active regions, wherein each active region is configured to emit electromagnetic radiation from a respective emitter region; and
a mounting surface facing the radiation emitting surface, wherein the mounting surface comprises a plurality of first solderable contact surfaces and a second solderable contact surface;, wherein:
each active region is suppliable with current with a respective first solderable contact surface and the second solderable contact surface;
the first solderable contact surfaces are arranged in an inner region of the mounting surface;
the second solderable contact surface is arranged in an edge region of the mounting surface;
a recess is arranged in the semiconductor layer sequence from a side facing the mounting surface;
the recess completely penetrates the active regions;
a second electrically conductive layer is arranged in the recess;
an electrically conductive connection layer is arranged on the second electrically conductive layer;
an electrically conductive connection layer is arranged on the semiconductor layer sequence;
the electrically conductive connection layer is electrically conductively connected to the second solderable contact surface; and
the electrically conductive connection layer is at least 5 nanometres and at most 20 nanometres thick.
