Abstract: In one embodiment, the optoelectronic semiconductor device comprises a semiconductor layer sequence and an electrical via. The semiconductor layer sequence includes an active zone for generating radiation and a contact layer for electrical contacting. The active zone lies in a plane perpendicular to a main growth direction of the semiconductor layer sequence and is located between a first semiconductor region and a second semiconductor region. The contact layer is located within the second semiconductor region. The via extends through the contact layer and preferably ends within the second semiconductor region. A contact surface between the via and the contact layer encloses a contact angle of at least 20° and at most 60° with respect to the plane.

Abstract: In an embodiment, an optoelectronic semiconductor component includes a semiconductor layer sequence with a doped first layer, a doped second layer, an active zone configured to generate radiation by electroluminescence between the first layer and the second layer, and a side surface extending transversely to the active zone and delimiting the semiconductor layer sequence in a lateral direction, two electrodes for electrical contact between the first and second layers and a cover layer located on the side surface in a region of the first layer, wherein the cover layer is in direct contact with the first layer, wherein a material of the cover layer alone and its direct contact with the first layer are configured to cause a formation of a depletion zone in the first layer, wherein the depletion zone comprises a lower concentration of majority charge carriers compared to a rest of the first layer, wherein the cover layer comprises a metal or a metal compound, and wherein the cover layer forms a Schottky contact with the first layer.
