Abstract

An optoelectronic semiconductor component includes a light-emitting semiconductor body having a radiation side, a current expansion layer arranged on the radiation side of the semiconductor body and at least partially covers this side, wherein the current expansion layer includes an electrically-conductive material transparent to the light radiated by the semiconductor body, and particles of a further material, and an electrical contact arranged on a side of the current expansion layer facing away from the semiconductor body.
