Abstract: An apparatus for the vacuum treatment of substrates in a vacuum chamber includes a substrate support device with a pylon which can be rotated about a longitudinal axis and has holding means for substrates and a plasma discharge device assigned to the pylon. The plasma discharge device includes more than two plate-shaped electrodes having excitation areas, the excitation areas of which are all oriented in the direction of the pylon and a power supply device for the excitation of a plasma discharge, by at least one electrical voltage applied to at least two of the electrodes, is provided, the excited plasma acting at least on parts of the pylon and on substrates that can be arranged on them. A process performs the vacuum coating by the apparatus.

Abstract: The invention relates to a device for vacuum coating substrates in a vacuum chamber, comprising an elongated evaporator array having a plurality of evaporator elements arranged along a longitudinal axis and a first substrate carrier unit which is associated with the evaporator array and has a first pylon that can be rotated about a first axis and contains retaining means for substrates, wherein an angular offset of less than 10° is present between the longitudinal axis and the first rotational axis. The device is characterised in that at least one second substrate carrier unit is provided, which is associated with the evaporator array and has a second pylon that can be rotated about a second axis and contains retaining means for substrates, wherein an angular offset of less than 10° is present between the longitudinal axis and the second rotational axis.
