Abstract
The invention relates to a radiation-emitting semiconductor chip comprising a semiconductor layer sequence having at least two active regions which generate electromagnetic radiation during operation and at least one reflective outer surface which is arranged to the side of each active region wherein the reflective outer surface includes an angle of at least 35° and at most 55° with a main extension plane of the semiconductor chip. The invention also relates to a method for producing a radiation-emitting semiconductor chip.
