Abstract

An optoelectronic semiconductor component includes an optoelectronic semiconductor chip having side areas, a surface at a top side of the semiconductor chip, and a surface at a bottom side of the semiconductor chip; a shaped body having a surface at a top side of the shaped body and a surface at an underside of the shaped body; at least one plated-through hole including an electrically conductive material; and an electrically conductive connection electrically conductively connected to the semiconductor chip and the plated-through hole, wherein the side areas of the optoelectronic semiconductor chip are covered by the shaped body, and the surface at the top side and/or the surface at the bottom side of the optoelectronic semiconductor chip are completely free of the shaped body.
