Abstract

An optoelectronic semiconductor body for emitting electromagnetic radiation from the front side with a semiconductor layer sequence and a first electrical contact layer, wherein the semiconductor layer sequence comprises at least one opening that penetrates fully through the semiconductor layer sequence in the direction from the front side to the rear side that is opposite the front side, the first electrical contact layer is arranged at the rear of the semiconductor body, a section of the first electrical contact layer extends from the rear side through the opening to the front side and covers a first sub-region of a front-side main face of the semiconductor layer sequence, and a second sub-region of the front-side main face is not covered by the first electrical contact layer.
