Abstract

An optoelectronic semiconductor chip has an active layer containing a photon-emitting zone. The active layer is attached to a carrier member at a bonding side of the active layer. The active layer has at least one recess therein with a cross-sectional area that decreases with increasing depth into said active layer proceeding from said bonding side.
