Claim:
1. An optoelectronic semiconductor chip comprising: a semiconductor layer sequence having an active layer; a top-side contact structure on a radiation main side of the semiconductor layer sequence; an underside contact structure on an underside of the semiconductor layer sequence opposite to the radiation main side, wherein, as seen in a plan view of the radiation main side, the top-side contact structure and the underside contact structure are spaced apart from one another in at least one region such that in a projection onto a plane in parallel with the radiation main side, the top-side contact structure and the underside contact structure do not overlap and/or contact one another in the at least one region; and a plurality of trenches extending from the radiation main side in a direction towards the underside, wherein the trenches in the at least one region are arranged between the top-side contact structure and the underside contact structure, and wherein the underside contact structure is formed by a plurality of islands located between contact fingers.
