Classification: CPC H | IPC H

Claim 0:
1. An optoelectronic semiconductor component comprising:
a semiconductor layer sequence with an active zone for generating a radiation, and the semiconductor layer comprises a light emission side, a bottom side that is opposite the light emission side, and an electrode that is arranged on the light emission side;
an electrically insulating separation layer having a plurality of openings, and the electrically insulating separation layer is positioned against the bottom side of the semiconductor layer sequence;
an adhesion-promoting layer provided next to the plurality of openings, and positioned on a side of the electrically insulating separation layer that is facing away from the semiconductor layer sequence; and
a continuous metallization layer positioned on a side of the adhesion-promoting layer that is facing away from the semiconductor layer sequence;
wherein the semiconductor layer sequence is in direct electrical contact with the continuous metallization layer within the plurality of openings of the electrically insulating separation layer, such that the continuous metallization layer directly adjoins the bottom side of the semiconductor layer sequence inside the plurality of openings,
wherein the continuous metallization layer and the plurality of openings are spaced from the active zone in a direction perpendicular to the separation layer,
wherein the openings are frustoconical in shape and have a diameter of at most 10 μm at the bottom side,
wherein the plurality of openings are spaced apart from one another, such that the electrically insulating separation layer adjoins the bottom side of the semiconductor layer sequence at any position laterally beside the plurality of opening, and the electrically insulating separation layer and the adhesion-promoting layer are arranged in between directly adjacent openings, and
wherein the plurality of openings in the electrically insulating separation layer do not overlap with the electrode in the semiconductor layer sequence in a top view of the optoelectronic semiconductor component.
