  • Patent number: 5180948
    Abstract: The present invention is directed to a plasma generator which can generate a localized plasma. To localize the plasma, a low pressure plasma generator, containing a vacuum chamber and at least one microwave radiation source, which does not by itself produce a field strength sufficient to form plasma in the vacuum chamber, is equipped with at least one aerial for the radiation of microwaves. This at least one aerial acts as a secondary radiator in the vacuum chamber and can generate a localized plasma at its free tips.
