The invention relates to an opto-electronic semiconductor body having a semiconductor layer sequence (2) comprising an active layer (23) suitable for generating electromagnetic radiation and a first and a second electrical connection layer (4, 6), wherein the semiconductor body is intended for the emission of electromagnetic radiation from a front side, the first and second electrical connection layers being located on a rear side opposite the front side and electrically insulated from each other by means of a separating layer (5), the first electrical connection layer (4), second electrical connection layer (6), and the separating layer (5) laterally overlapping each other, and a partial area of the second electrical connection layer (6) extending from the rear side through a penetration (3) through the active layer (23) in the direction of the front side. The invention further relates to a method for producing such an opto-electronic semiconductor body.
