Claim 6:
7. A method for producing an optoelectronic semiconductor device comprising:
forming a layer stack comprising a first semiconductor layer of a first conductivity type and a second semiconductor layer of a second conductivity type, wherein the first semiconductor layer is arranged on a side facing away from a first main surface of the second semiconductor layer, and electromagnetic radiation emitted by the optoelectronic semiconductor device is output via the first main surface of the second semiconductor layer;
forming a first contact element for contacting the first semiconductor layer; and
forming a second contact element for contacting the second semiconductor layer;
forming a first current spreading layer electrically connected to the first semiconductor layer and to the first contact element, between the first semiconductor layer and the first contact element;
forming a second current spreading layer electrically connected to the second semiconductor layer and to the second contact element, between the second semiconductor layer and the second contact element and have a height of more than 50 μm, the second current spreading layer horizontally extending along the first semiconductor layer and forming a carrier element;, wherein:
the first contact element and the second contact element are each arranged on a side of a first main surface of the first semiconductor layer;
the first current spreading layer is arranged on a side of the first main surface of the first semiconductor layer;
the second current spreading layer is arranged on a side of the first main surface of the first semiconductor layer; and
the first contact element and the second contact element each comprises a first section extending in a first direction, and a plurality of second sections which are each connected to the first section and extend in a second direction different from the first direction, wherein the second sections of the first contact element and the second contact element are each arranged alternately,

the method further comprising forming openings in the second current spreading layer, the first contact element being formed so as to contact the first current spreading layer through the openings.
