Abstract
An optoelectronic semiconductor chip includes a semiconductor layer sequence having at least one active layer. Furthermore, the semiconductor chip has a top-side contact structure on a radiation main side of the semiconductor layer sequence and an underside contact structure on an underside situated opposite to the radiation main side. Furthermore, the semiconductor chip includes at last two trenches that extend from the radiation main side towards the underside. As seen in a plan view of the radiation main side, the top-side contact structure and the underside contact structure are arranged in a manner spaced apart from one another. Likewise as seen in a plan view of the radiation main side, the trenches are located between the top-side contact structure and the underside contact structure.
