摘要:
An antenna includes excitation terminals responsive to an RF source to supply an RF electromagnetic field to a plasma that processes a workpiece in a vacuum chamber. The coil includes a transformer having a primary winding coupled to the excitation terminals and a multi-turn plasma excitation secondary winding connected in series with a capacitor.
