Abstract: The method involves providing an assembly of a semiconductor body (2) to generate electromagnetic radiation, in an assembly region (3) of a carrier (4). A frame (5) is formed circumstantially at the assembly region on the carrier by a photo-structure. A sealing compound is provided with a diffuser particle and is arranged inside the frame. The frame is removed after the arrangement and/or filling with the sealing compound. A window is made of glass or plastic, where the sealing compound is epoxy resin or silicone resin.

Abstract: The method involves providing a screen (103) with openings (105) that are provided at positions at which a recess (104) of a carrier element (101) is to be closed. The recess of the carrier element is filled by the screen through screen printing of a viscous mass (102) e.g. soldering metal. The viscous mass is hardened by heating of the carrier element that is printed with soldering metal, where the viscous mass carries semiconductor components. The carrier element is preferably made of ceramic substrate.
