A radiation-emitting semiconductor chip includes a substrate; an epitaxial semiconductor layer sequence having an active zone that generates electromagnetic radiation of a first wavelength range, wherein the substrate is transparent to electromagnetic radiation of the active zone; and an optically active layer arranged on a side surface of the substrate and on a rear main surface of the semiconductor chip, which lies opposite to a radiation exit surface of the semiconductor chip.

Radiation-emitting semiconductor chip, optoelectronic component comprising a radiation-emitting semiconductor chip, and method of coating a radiation-emitting semiconductor chip

A method to ensure uniform deposition of organic layer is disclosed. Since the organic layer is very thin, any deviation from the target thickness will result in visible optical defects. A homogenous layer which exhibits good coating behaviour with organic materials is provided beneath the organic layer. By covering the metal interconnects, the adverse effect on the uniformity of the polymer layer is reduced or prevented.
