  • Process and apparatus for the plasma coating of workpieces with spectral evaluation of the process parameters
    Patent number: 8397667
    Abstract: The invention provides a process for coating workpieces by plasma-induced chemical vapor deposition, in which a process gas is introduced into a coating chamber and a plasma is ignited by electromagnetic energy in at least one region of the coating chamber which adjoins the workpiece and in which the process gas is present, wherein the coating operation is monitored on the basis of at least one measured spectral parameter of the plasma, and the workpiece is removed in the event of a deviation from a desired range for the parameter.

  • Method and apparatus for treating substrates in a rotary installation
    Patent number: 7811384
    Abstract: The invention relates to a method and an apparatus for the treatment of substrates, in particular for the coating of plastic containers on a rotary installation. A plurality of treatment devices are arranged on the rotor and pass through a plurality of process phases as a function of their angle position on the rotor. For at least one process phase, the angle position can be set variably as a function of the current rotational speed of the rotor.
