Abstract:
1. A light-emitting diode chip comprising: an n-conducting semiconductor layer; a p-conducting semiconductor layer; an active region between the n-conducting semiconductor layer and the p-conducting semiconductor layer; a side face delimiting the n-conducting semiconductor layer, the p-conducting semiconductor layer, and the active region in a lateral direction; a doping region, in which a dopant is introduced into a semiconductor material of the light-emitting diode chip wherein the doping region is formed at the side face at least in the region of the active region, and the light-emitting diode chip is provided for emitting incoherent electromagnetic radiation during operation, wherein the doping region forms an electrical passivation at the side face, and wherein a dopant in the doping region converts an n-conducting region in the region of the side face at or around the active region into a p-conducting region or a p-conducting region in the region of the side face at or around the active region into an n-conducting region.
