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 1):
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, 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.
