摘要:
A plasma processing system for etching a substrate using a highly dense plasma in a reactor. An ICP coil having a first coil end and a second coil end generating a high-frequency electromagnetic alternating field in the reactor which acts on a reactive gas and, as an inductively coupled plasma source, produces the highly dense plasma from reactive particles and ions. The two coil ends each communicate via a feed point with a high-frequency infeed, which applies in each case a high-frequency a.c. voltage of the same frequency to the first coil end and to the second coil end (21, 21′). The two high-frequency a.c. voltages applied at the two coil ends are connected to a symmetrical, capacitive network via a &lgr;2 -delay line linking the first feed point and the second feed point and are, at least nearly in phase opposition to one another, and have at least nearly the same amplitudes.

The tool comprises one or more core-coil assemblies 2 jacketed in an non-magnetic and electrically insulating, tubular outer housing, 10. The housing enables high power transfer efficiency. A structural skeleton 20 extends longitudinally through the tool for axially reinforcement. The core-coil assemblies 2 are encapsulated in epoxy 77 to mechanically rigidify and protect them as well as to isolate the coil windings 51 from the power bus 23 extending longitudinally of the core-coil assemblies through a peripheral busway 60, 61.

A method and a magnetic levitation vehicle operating with this method are described. For the control of support gaps (10a, 10b) that are formed during operation of the magnetic levitation vehicle (1) between a track (2, 3, 4) and a number of carrying magnets (6a, 6b) fastened to said magnetic levitation vehicle (1) and provided with windings (16a, 16b), wherein at least two carrying magnets (6a, 6b) in adjacent positions act upon a suspension frame (8) of said magnetic levitation vehicle (1), the electrical currents flowing through the windings (16a, 16b) are so controlled that the support gaps (10a, 10b) between these two carrying magnets (6a, 6b) and the track (2, 3, 4) adopt pre-determined nominal values (na, nb). In accordance with the invention and in case that the currents through the windings (16a, 16b) of the adjacent carrying magnets (6a) are different under normal conditions, the nominal values (na, nb) for the support gaps (10a, 10b) are altered such that the current through the windings (16a or 16b) of a carrying magnet (6a, 6b) with the lower electric current is increased and/or the electric current through the winding (16b and/or 16a) of a carrying magnet (6b, 6a) with the larger electric current is reduced.

摘要:
A method and device for sterilizing containers in which a plasma treatment is executed through excitation of an electromagnetic oscillation so that the plasma is excited in a vacuum in the vicinity of the container regions to be sterilized. Between arrival and discharge, the container regions to be sterilized are moved closer to the oscillation-generating device in the chamber, with continuous movement of the container and/or of the oscillation-generating device for one or more predetermined time intervals in such a way that a plasma is excited in these regions inside and/or outside the container. The chamber is provided with a transport apparatus inside it, which produces an essentially rotating motion of the container during the transport from the arrival to the discharge in the chamber.
