Abstract
A radiation-emitting semiconductor chip includes a carrier and a semiconductor body having a semiconductor layer sequence, wherein an emission region and a protective diode region are formed in the semiconductor body having the semiconductor layer sequence; the semiconductor layer sequence includes an active region that generates radiation and is arranged between a first semiconductor layer and a second semiconductor layer; the first semiconductor layer is arranged on a side of the active region facing away from the carrier; the emission region has a recess extending through the active region; the first semiconductor layer, in the emission region, electrically conductively connects to a first connection layer, wherein the first connection layer extends in the recess from the first semiconductor layer toward the carrier; the second semiconductor layer, in the emission region, electrically conductively connects to a second connection layer.
