Classification: CPC H | IPC H

Claim 4:
5. An optoelectronic device comprising:
an optoelectronic semiconductor chip configured to emit electromagnetic radiation; wherein the optoelectronic semiconductor chip comprises:
a first semiconductor layer having a first conductivity type;
a second semiconductor layer having a second conductivity type;
a first current spreading layer and a second current spreading layer; and
a plurality of electrical contact elements;
wherein the first semiconductor layer is arranged over the second semiconductor layer;
wherein electromagnetic radiation emitted by the optoelectronic semiconductor chip is output via a first main surface of the first semiconductor layer;
wherein the first current spreading layer is arranged on a side of the second semiconductor layer facing away from the first semiconductor layer;
wherein the plurality of electrical contact elements is configured to electrically connect the first semiconductor layer to the first current spreading layer;
wherein the second current spreading layer is electrically connected to the second semiconductor layer; and
wherein the electrical contact elements comprise a first electrical contact element and a second electrical contact element; wherein the first electrical contact element is different from the second electrical contact element;
wherein the second current spreading layer is arranged between the first current spreading layer and the second semiconductor layer, wherein an insulating layer insulates the first electrical contact element and the second electrical contact element from the second current spreading layer; and
wherein a first insulating layer is adjacent to the first contact element and comprises a first laterally measured layer thickness and a second insulating layer is adjacent to the second contact element and comprises a second laterally measured layer thickness, and wherein the first laterally measured layer thickness is different from the second laterally measured layer thickness so that a distance between the first contact element to the second current spreading layer is different from the distance between the second contact element to the second current spreading layer.
