Abstract

A semiconductor chip includes a semiconductor body with a semiconductor layer sequence. An active region intended for generating radiation is arranged between an n-conductive multilayer structure and a p-conductive semiconductor layer. A doping profile is formed in the n-conductive multilayer structure which includes at least one doping peak.
