Abstract: Provided is a plasma reactor for removal of contaminants, which is installed between a process chamber and a vacuum pump and removes contaminants emitted from a process chamber. The plasma reactor includes: at least one dielectric body that forms a plasma generation space therein; a ground electrode connected to at least one end of the dielectric body; and at least one driving electrode fixed to an outer peripheral surface of the dielectric body, and connected to an AC power supply unit to receive an AC driving voltage. The ground electrode has a non-uniform diameter along the lengthwise direction of the plasma reactor.
