Abstract
A method for producing a radiation emitting semiconductor chip may include providing a semiconductor layer sequence having an active region configured to generate electromagnetic radiation, applying a reflective layer sequence over the semiconductor layer sequence, generating a first recess through an opening of a mask where the first recess completely penetrates the reflective layer sequence and the active region, and applying a dielectric mirror layer in the first recess through the same opening of the same mask. Furthermore, a radiation emitting semiconductor chip is disclosed.
