Abstract: An optoelectronic semiconductor body includes a semiconductor layer sequence which has an active layer suitable for generating electromagnetic radiation, and a first and a second electrical connecting layer. The semiconductor body is provided for emitting electromagnetic radiation from a front side. The first and the second electrical connecting layer are arranged at a rear side opposite the front side and are electrically insulated from one another by means of a separating layer. The first electrical connecting layer, the second electrical connecting layer and the separating layer laterally overlap and a partial region of the second electrical connecting layer extends from the rear side through a breakthrough in the active layer in the direction of the front side. Furthermore, a method for producing such an optoelectronic semiconductor body is specified.
