ABSTRACT:
A semiconductor chip (1) comprises a semiconductor body (2) having a semiconductor layer sequence having an active region (23) provided for generating radiation. A contact (4) is arranged on the semiconductor body (2). An injection barrier (5) is formed between the contact (4) and the active region (23). A method for producing a semiconductor chip is also disclosed.
