Claim Text:
1. A method for producing an optoelectronic semiconductor chip comprising the following method steps performed in the indicated order: providing an n-conducting layer; arranging a p-conducting layer on the n-conducting layer, wherein at least one active zone provided for receiving and/or for emitting electromagnetic radiation during the operation of the optoelectronic semiconductor chip is formed between the n-conducting layer and the p-conducting layer; arranging a metal layer sequence on the p-conducting layer; arranging a mask at a side of the metal layer sequence which is remote from the p-conducting layer; in places removing the metal layer sequence and uncovering the p-conducting layer using the mask; and in places neutralizing or removing the uncovered regions of the p-conducting layer as far as the n-conducting layer using the mask, wherein the metal layer sequence comprises at least one mirror layer and a barrier layer, and the mirror layer of the metal layer sequence faces the p-conducting layer.
