  • Patent number: 9437403
    Abstract: An arrangement is provided for feeding in HF current for rotatable tubular cathodes in a vacuum chamber of a plasma coating system as well as a high frequency current source. Located inside the tubular cathode is a magnet arrangement that extends along said tubular cathode for generating a magnetic field. The arrangement enables a low loss infeed of HF current, so that a particularly homogeneous sputter removal from the tubular cathode is guaranteed. The HF current source is coupled to the tubular cathode inside the vacuum chamber by a capacitive infeed of HF current in the form of a coupling capacitor. The coupling capacitor includes a part of the surface of the tubular cathode and a metal plate or metal film that surrounds the tubular cathode, at least partially, at a specified distance.

  • Publication number: 20150059646
    Abstract: A vapor-deposition device for coating two-dimensional substrates with an organic material. The substrates can be positioned within a vacuum chamber above a process chamber or can be moved past the latter by a transport device. A vaporizer for an organic coating material is arranged within the process chamber and opposite the substrates. The process chamber is delimited laterally by shields which, opposite the substrates, extend as far as a feed device for the coating material. The vaporizer includes the feed device for the coating material and radiant heaters underneath the same. This arrangement can achieve, with a high vaporization rate, good homogeneity of the layer thickness and of the layer stoichiometry.
