Abstract

An optoelectronic semiconductor component includes a semiconductor chip having a semiconductor layer sequence including an active region that generates radiation; a radiation exit surface running parallel to the active region; a mounting side surface that fixes the semiconductor component and runs obliquely or perpendicularly to the radiation exit surface and at which at least one contact area for external electrical contacting is accessible; a molded body molded onto the semiconductor chip in places and forming the mounting side surface at least in regions; and a contact track arranged on the molded body and electrically conductively connecting the semiconductor chip to the at least one contact area.

Claims
