Hybrid plasma reactor
A hybrid plasma reactor includes a first plasma chamber for providing a first ring-shaped plasma discharge space, second plasma chambers providing a second plasma discharge space connected to the first plasma discharge space and coupled to magnetic flux channels, a hybrid plasma source including magnetic cores, which partially surround the first plasma chamber and have magnetic entrances forming the magnetic flux channels, and primary winding coils wound in the magnetic cores and complexly generating ring-shaped transformer-coupled plasma in the first plasma discharge space and magnetic flux channel coupled plasma in the second plasma discharge space, and an AC switching power supply for supplying plasma generation power to the primary winding coils. The hybrid plasma reactor can complexly generate magnetic flux channel coupled plasma and transformer coupled plasma so that it has a high control capability for plasma ion energy and a wide operation region from a low-pressure region to a high-pressure region.
