1. An optoelectronic semiconductor chip comprising:
a semiconductor layer sequence with an active zone for generating a radiation;
a metal mirror for the radiation;
a protective metallization on a side of the metal mirror facing away from the semiconductor layer sequence; and
an adhesion promoting layer on a side of the metal mirror facing the semiconductor layer sequence,
wherein the adhesion promoting layer is an encapsulation layer for the metal mirror so that the metal mirror is completely encapsulated at an outer edge by the adhesion promoting layer together with the protective metallization.
