Abstract:
1. An inductive plasma applicator comprising: a support member with a generally flat plate shape, adapted for forming part of or being arranged on a vacuum vessel wall, said support member having a front surface intended to be oriented towards an inner volume of the vacuum vessel, a back surface and possibly additional surfaces intermediate between the front and back surfaces, said surfaces being parallel to each other; at least one ferromagnetic inductively coupled plasma source including: at least one electrode having a hole pattern centred with respect to the coil and adapted not to inhibit the magnetic flux bundle from extending in the inner volume of the vacuum vessel, said electrode being further adapted for forming a capacitor with another electrode external to the applicator; wherein the coil of the ferromagnetic inductively coupled plasma source and the electrode comprise respective metal track portions distributed on the surfaces of the support member, with the metal track portions of the electrode being located closer to the inner volume of the vacuum vessel than the metal track portions of the coil.
