OPTOELECTRONIC SEMICONDUCTOR CHIP AND METHOD FOR PRODUCING AN OPTOELECTRONIC SEMICONDUCTOR CHIP
In at least one embodiment, the optoelectronic semiconductor chip (100) comprises a semiconductor layer sequence (1) having an active layer (10), a doped current spreading layer (11) and an output coupling layer (12), which are arranged one above the other in this order. The active layer generates p...

| description | In at least one embodiment, the optoelectronic semiconductor chip (100) comprises a semiconductor layer sequence (1) having an active layer (10), a doped current spreading layer (11) and an output coupling layer (12), which are arranged one above the other in this order. The active layer generates primary radiation during intended operation. The current spreading layer comprises a larger lateral electrical conductivity than the output coupling layer. The output coupling layer comprises output coupling structures (121) for coupling out radiation on an exit side (120) facing away from the active layer. The output coupling layer comprises a lower absorption coefficient for primary radiation than the current spreading layer. |
