Abstract
An optoelectronic semiconductor device may include a first semiconductor layer and a second semiconductor layer, the first and second semiconductor layers being stacked one above the other. The device may include a first contact structure and a contact layer. The device may include a separating layer arranged over a side of the contact layer, and a current spreading layer arranged over a side of the separating layer facing away from the contact layer. The first contact structure may be connected to the contact layer via the current spreading layer and the separating layer. A layer stack may include the contact layer, the separating layer, and the current spreading layer has an anisotropic conductivity. The separating layer is present as a continuous layer in a region between the contact layer and the current spreading layer.
