Abstract
A radiation-emitting semiconductor body is provided which, besides an epitaxial semiconductor layer sequence having an active zone that is suitable for generating electromagnetic radiation, has a carrier layer that is intended to mechanically stabilize the epitaxial semiconductor layer sequence. The semiconductor body furthermore has contact structures for electrical contacting of the semiconductor body, which respectively have a volume region and a surface bonding region. The surface bonding region is formed from a material which is different from the material of the volume region.
