Abstract

A light-emitting diode chip and a method for manufacturing a light-emitting diode chip are disclosed. In an embodiment a light-emitting diode chip includes an epitaxial semiconductor layer sequence having an active zone configured to generate electromagnetic radiation during operation and a passivation layer comprising statically fixed electrical charge carriers, wherein the passivation layer is located on a side surface of the semiconductor layer sequence covering at least the active zone.
