Abstract
An arrangement and a method for the production of gas-impermeable layers, in particular for the coating of gas-permeable synthetic material substrates. With the aid of this arrangement or of the method light-permeable as well as also light-impermeable gas-blocking layers are produced using only one sputtering installation. A simple change-over switching from one gas supply, for example argon, to a second gas supply, for example argon, oxygen and nitrogen is carried out or the converse.
