Abstract:
A method for producing an optoelectronic semiconductor chip is specified, wherein a method step A) involves providing a semiconductor layer stack comprising a semiconductor layer of a first type, a semiconductor layer of a second type and an active layer arranged between the semiconductor layer of the first type and the semiconductor layer of the second type. Furthermore, the method comprises in a method step B) forming a mesa structure in the semiconductor layer of the first type, the semiconductor layer of the second type and the active layer. The method furthermore comprises in a method step C) applying a passivation layer to the mesa structure by means of vapour deposition or sputtering.

Claim (Index 18):
A method for producing an optoelectronic semiconductor chip comprising the steps of:\n A) providing a semiconductor layer stack comprising a semiconductor layer of a first type, a semiconductor layer of a second type and an active layer arranged between the semiconductor layer of the first type and the semiconductor layer of the second type, A 0 ) applying an electrically conductive layer over the semiconductor layer of the first type or the semiconductor layer of the second type, A 1 ) applying a patterned mask on the semiconductor layer of the first type or on the semiconductor layer of the second type, B) forming a mesa structure in the semiconductor layer of the first type, the semiconductor layer of the second type and the active layer, whereby in forming the mesa structure, the electrically conductive layer on the semiconductor layer stack is at least partially removed, so that a gap between a mask and the semiconductor layer stack is generated, B 3 ) at least partially removing the electrically conductive layer in a region which directly adjoins the mesa structure and partially extends under the mask, by means of a wet-chemical etching process, C) application of a passivation layer to the mesa structure by means of vapor deposition or sputtering.
