Abstract
An optoelectronic semiconductor chip is disclosed. In an embodiment the optoelectronic semiconductor chip includes a first semiconductor layer sequence having a plurality of microdiodes, and a second semiconductor layer sequence having an active region. The first semiconductor layer sequence and the second semiconductor layer sequence are based on a nitride compound semiconductor material, the first semiconductor layer sequence is before the first semiconductor layer sequence in the direction of growth, and the microdiodes form an ESD protection for the active region.
