Claim:
1. A light-emitting diode chip comprising: a semiconductor body having a radiation-generating active region, at least two contact locations electrically contacting the active region, a carrier, and a connecting medium arranged between the carrier and the semiconductor body, wherein the semiconductor body comprises a roughening on outer surfaces facing the carrier, the semiconductor body mechanically connects to the carrier by the connecting medium, the connecting medium locally directly contacts the semiconductor body and the carrier, the at least two contact locations are arranged on the upper side of the semiconductor body facing away from the carrier, the roughening is arranged between the semiconductor body and the carrier, the roughening comprises elevations and depressions in the material comprising the semiconductor body, wherein at least some of the elevations completely reach through the connection medium, and peaks of the elevations protrude from the connecting medium, said protruding peaks being free of the connecting medium and in direct physical contact with the carrier.
