Abstract

A method for producing a plurality of radiation emitting semiconductor devices and a radiation emitting semiconductor device are disclosed. In an embodiment a method include providing an auxiliary carrier, applying a plurality of radiation-emitting semiconductor chips to the auxiliary carrier with front sides so that rear sides of the semiconductor chips are freely accessible, wherein each rear side of the respective semiconductor chip has at least one electrical contact, applying spacers to the auxiliary carrier so that the spacers directly adjoin side surfaces of the semiconductor chips and applying a casting compound between the semiconductor chips by a screen printing process such that a semiconductor chip assembly is formed, wherein a screen for the screen printing process has a plurality of cover elements, and wherein each cover element covers at least one electrical contact.
