ABSTRACT:
A process for encapsulating a component made of organic semiconductors is provided which includes steps of: a) providing a housing including a substrate with electrical connections and a cover; b) mixing a soldering glass with at least one of a binder and a solvent; c) applying the soldering glass at least to the cover, in the form of an encircling bank; d) expelling the binder or solvent; e) sintering-on of the solder; f) covering the substrate with layers which represent the semiconductor component together with electrodes; g) placing the cover onto the substrate; and h) locally heating the soldering glass by means of a light source with a predetermined peak wavelength, wherein the housing parts and soldering glass are matched to one another such that their coefficients of thermal expansion differ from one another by less than 1.0×10−6K−1.
