Abstract
An optoelectronic semiconductor device comprises 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, and 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; a first electrical connector on the first conductivity layer of the semiconductor system; a second electrical connector comprising a shape formed on the second conductivity layer of the semiconductor system; and a contact layer formed on the top surface of the second conductivity layer and having an outer perimeter at an inner side of the outline of the second conductivity layer in the top view of the semiconductor system, wherein the contact layer comprises a discontinuous region exposing the top surface of the second conductivity layer, the discontinuous region is formed along the shape of the second electrical connector.
