Abstract

An optoelectronic semiconductor component includes an optoelectronic semiconductor chip having a top area at a top side, a bottom area at an underside, and side areas connecting the top area and the bottom area; electrical contact locations at the top area or at the bottom area of the optoelectronic semiconductor chip; and an electrically insulating shaped body, wherein the optoelectronic semiconductor chip is a flip-chip having the electrical contract locations only at one side, either the underside or the top side, the shaped body surrounds the optoelectronic semiconductor chip at its side areas, and the shaped body is free of a via that electrically connects the optoelectronic semiconductor chip.
