Abstract
In the case of CVD methods, comprising PECVD and PICVD methods, the aim of the invention is to improve the impurity-free and, as far as possible, temporally and quantitatively precise feeding of process gases for the targeted layer systems. To this end, the invention provides a coating system and a method for coating articles with alternating layers, in the case of which process gases are introduced in an alternating fashion into a gas mixing point and mixed with a further gas and led to the reaction chamber, in which the deposition is carried out by producing a plasma.
