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.
