Abstract
A device for covering a substrate by means of both plasma chemical vapor deposition and by high-frequency cathode sputtering which, as a result of easily exchangeable individual devices to introduce gaseous substances into the reaction space as well as easily exchangeable individual devices for influencing the flow of the process gases within the reaction space, results in a very good uniformity of the layer thickness of the produced layers even when the operation has to be carried out at higher gas pressures and hence higher flow rates.
