Optoelectronic semiconductor chip having a plurality of active regions arranged alongside one another
Abstract:
An optoelectronic semiconductor chip is disclosed. The optoelectronic semiconductor chip includes a semiconductor layer sequence having an active zone suitable for emitting radiation, a carrier substrate, and a mirror layer, the mirror layer being arranged between the semiconductor layer sequence and the carrier substrate, wherein the semiconductor layer sequence is subdivided into a plurality of active regions arranged alongside one another, wherein the plurality of active regions are separated from one another in each case by a trench in the semiconductor layer sequence, wherein the trench in each case severs the semiconductor layer sequence and the mirror layer, wherein the mirror layer has side surfaces facing a trench and side surfaces facing an outer side of the semiconductor chip, wherein the side surfaces of the mirror layer that face an outer side of the semiconductor chip have a metallic encapsulation layer.
