Abstract
An optoelectronic semiconductor chip includes a semiconductor layer stack consisting of a nitride compound semiconductor material on a carrier substrate, wherein the carrier substrate includes a surface containing silicon. The semiconductor layer stack includes a recess extending from a back of the semiconductor layer stack through an active layer to a layer of a first conductivity type. The layer of the first conductivity type connects electrically to a first electrical connection layer which covers at least a portion of the back through the recess. The layer of a second conductivity type connects electrically to a second electrical connection layer arranged at the back.
