Abstract

An optoelectronic semiconductor chip has a non-rectangular, parallelogram-shaped top surface and an active zone, which is at a distance from the top surface and runs parallel to the top surface at least in places. The top surface includes a radiation exit surface, through which electromagnetic radiation generated during operation in the active zone emerges. The radiation exit surface has at least four vertices. The top surface includes at least one triangular connection area via which the active zone is electrically connectable.
