Abstract

A semiconductor chip with a layer stack includes a first semiconductor layer sequence and a second semiconductor layer sequence. The first semiconductor layer sequence includes a first semiconductor region of a first conductivity type, a second semiconductor region of a second conductivity type and an active zone arranged therebetween. The second semiconductor layer sequence includes the second semiconductor region of the second conductivity type, a third semiconductor region of the first conductivity type and a second active zone arranged therebetween.
