  • Patent number: 10685813
    Abstract: The invention relates to a plasma treatment device with a treatment chamber, at least one pair of microwave plasma sources and at least one voltage source. Each pair of microwave plasma sources consists of a first microwave plasma source and a second microwave plasma source, wherein the first and the second microwave plasma source each have a plasma source wall and, within this, a microwave coupling-in device and a plasma electrode. The first and the second microwave plasma source are arranged within the treatment chamber on the same side of one or more substrates to be processed and adjacently to one another. The plasma electrodes of the first microwave plasma source and the second microwave plasma source are electrically insulated from one another and electrically conductively connected to the at least one voltage source. Here, the at least one voltage source is suitable for supplying the plasma electrodes of the first and the second microwave plasma source with different potentials.

    Abstract: In an ion implantation device and a method for the ion implantation of a substrate, plasma having an ion density of at least 1010 cm?3, is generated by a plasma source in a discharge space. The discharge space is delimited in the direction of the substrate to be implanted by a plasma-delimiting wall. The plasma-delimiting wall being at a plasma potential, and a pressure in the discharge space is higher than the pressure in the space in which the substrate is situated in the ion implantation device. The substrate bears on a substrate support, with its substrate surface opposite the plasma-delimiting wall. The substrate and/or the substrate support are/is utilized as a substrate electrode, which is put at a high negative potential relative to the plasma that ions are accelerated from the plasma in the direction of the substrate and implanted into the substrate.

  • Patent number: 8790498
    Abstract: A method and device for ion beam processing of surfaces of a substrate positions the substrate to face an ion beam, and a new technologically-defined pattern of properties is established. According to the method, the current geometrical effect pattern of the ion beam on the surface of the substrate is adjusted depending on the known pattern of properties and the new technologically-defined pattern of properties, and depending upon the progress of the processing, by modifying the beam characteristic and/or by pulsing the ion beam. A device for carrying out the method includes a substrate support for holding at least one substrate, which can be moved along an Y-axis and an X-axis, and an ion beam source for generating an ion beam, which is perpendicular to the surface to be processed of the substrate in the Z-axis or which may be arranged in an axis, inclined in relation to the Z-axis. The distance between the ion beam source and the surface to be processed of the substrate may be fixed or variable.
