Abstract:
A method for producing an optoelectronic semiconductor chip is specified, comprising the following steps: providing an n-conducting layer (2), arranging a p-conducting layer (4) on the n-conducting layer (2), arranging a metal layer sequence (5) on the p-conducting layer (4), arranging a mask (6) at that side of the metal layer sequence (5) which is remote from the p-conducting layer (4), in places removing the metal layer sequence (5) and uncovering the p-conducting layer (4) using the mask (6), and in places neutralizing or removing the uncovered regions (4a) of the p-conducting layer (4) as far as the n-conducting layer (2) using the mask (6), wherein the metal layer sequence (5) comprises at least one mirror layer (51) and a barrier layer (52), and the mirror layer (51) of the metal layer sequence (5) faces the p-conducting layer (4).
