Claim Text:
1. An optoelectronic semiconductor device, comprising: a substrate; a semiconductor system including a first conductivity layer, a second conductivity layer, and a conversion unit between the first conductivity layer and the second conductivity layer, wherein the first conductivity layer is closer to the substrate than the second conductivity layer is to the substrate, the second conductivity layer comprises a top surface perpendicular to a thickness direction of the semiconductor system, and in a top view of the semiconductor system, an outline of the first conductivity layer surrounds an outline of the second conductivity layer; an electrical connector on the semiconductor system; a contact layer having an outer perimeter extending around an entire outer edge of the contact layer and being at an inner side of the outline of the second conductivity layer in the top view of the semiconductor system; and at least three successive discontinuous regions connecting to the outer perimeter, extending inwardly from the outer perimeter in a non-periodic pattern, and extending parallel to the top surface of the second conductivity layer, wherein the at least three successive discontinuous regions have at least one different factor, and a bottom of the at least three successive discontinuous regions exposes the top surface of the second conductivity layer.
