Abstract
An optoelectronic semiconductor chip has a first semiconductor layer sequence which comprises a multiplicity of microdiodes, and a second semiconductor layer sequence which comprises 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.
