    Abstract: An optoelectronic device may include an optoelectronic semiconductor chip that is configured to emit electromagnetic radiation. The chip may include a first semiconductor layer, a second semiconductor layer, first and second current spreading structures, and a plurality of electrical contact elements. The first current spreading layer may be arranged on a side of the second semiconductor layer facing away from the first semiconductor layer. The plurality of electrical contact elements may electrically connect the first semiconductor layer to the first current spreading layer. The second current spreading layer may be electrically connected to the second semiconductor layer. The second current spreading layer may be arranged between the first current spreading layer and the second semiconductor layer where an insulating layer insulates a first electrical contact element and a second electrical contact element from the second current spreading layer.
