摘要： An exhaust pipe device according to an embodiment includes a dielectric pipe; a radio-frequency electrode; a ground electrode; and a plasma generation circuit. The radio-frequency electrode is disposed on an outer periphery side of the dielectric pipe and a radio-frequency voltage is applied to the radio-frequency electrode. The ground electrode is disposed on an end portion side of the dielectric pipe such that a distance from the radio-frequency electrode is smaller on an inner side than on an outer side of the dielectric pipe, and a ground potential is applied to the ground electrode. The plasma generation circuit generates plasma inside the dielectric pipe. The exhaust pipe device functions as a part of an exhaust pipe disposed between a film forming chamber and a vacuum pump that exhausts gas inside the film forming chamber.

摘要： A low-temperature plasma reactor having an adaptive rotating electrode includes a frame. A reaction tube is arranged inside the frame. A fixing cover is arranged on each of two sides of the frame. The fixing cover defines a through hole communicating with an inside of the reaction tube. The through hole in one of the two sides serves as an air inlet hole, and the through hole in the other one of the two sides serves as an air outlet hole. A rotatable inner electrode is arranged inside the reaction tube, a plurality of groups of discharging needles are arranged on a surface of the inner electrode. A rotating fan is arranged on the inner electrode and is disposed on a side of the air inlet hole. The gas flow drives the inner electrode and the discharging needles to rotate, and a motor drive is not required.
