An inductive plasma applicator comprises a ferromagnetic inductively coupled source and an electrode with a hole pattern centered with respect to the plasma source. Such plasma applicator provides an efficient energy transfer to the plasma. The plasma applicator is preferably manufactured using a technology for producing electrical circuits. The electrode and a coil of the ferromagnetic inductively coupled plasma source are metal track portions formed on an insulating substrate. For example, the plasma applicator is manufactured using printed circuit board technology.
