Patent ID: 7533628

Claim:
A device for coating of substrates, comprising: a coating chamber; a first partial device having a first waveguide for coupling in microwave energy, a first gas supply line and a first apparatus for evacuating the coating chamber, a second partial device having a second waveguide for coupling in microwave energy, a second gas supply line and a second apparatus for evacuating the coating chamber; the first and second partial devices being movable relative to each other, where by means of such moving the coating chamber in which the substrate to be coated is placed can be opened and closed; the first waveguide for coupling in microwave energy, the first gas supply line and the first apparatus for evacuating the coating chamber are disposed concentric to each other, and the second waveguide for coupling in microwave energy and the second gas supply line and the second apparatus for evacuating the coating chamber are disposed concentric to each other; the coating chamber being a removable and exchangeable coating chamber; the removable and exchangeable coating chamber having an internal shape that is symmetrical to the shape of the substrate to be coated and including microwave windows for coupling in microwave energy that are part of the removable and exchangeable coating chamber; the waveguide and treatment chamber disposed concentric to each other.
