Abstract
A radiation emitting semiconductor chip may be configured to emit electromagnetic radiation from a radiation exit surface during operation. The chip may include a carrier on which a first epitaxial semiconductor layer sequence of a first conductivity type and a second epitaxial semiconductor layer sequence of a second conductivity type different from the first conductivity type are arranged, a first current spreading layer arranged between the first semiconductor layer sequence and the carrier, a second current spreading layer arranged between the first current spreading layer and the carrier, a dielectric layer arranged in regions between the first current spreading layer and the second current spreading layer, a reflective layer arranged between the second current spreading layer and the carrier, and an electrically insulating layer arranged in regions between the second current spreading layer and the reflective layer.
