Abstract:
A light-emitting diode chip includes a semiconductor body including 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 includes 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, and the at least two contact locations are arranged on the upper side of the semiconductor body facing away from the carrier.
