摘要： The present invention aims at providing a radio-frequency antenna unit capable of generating a high-density discharge plasma in a vacuum chamber. The radio-frequency antenna unit according to the present invention includes: a radio-frequency antenna through which a radio-frequency electric current can flow; a protective tube made of an insulator provided around the portion of the radio-frequency antenna that is in the vacuum chamber; and a buffer area provided between the radio-frequency antenna and the protective tube. The “buffer area” refers to an area where an acceleration of electrons is suppressed, and it can be formed, for example, with a vacuum or an insulator. Such a configuration can suppress an occurrence of an electric discharge between the antenna and the protective tube, enabling the generation of a high-density discharge plasma in the vacuum chamber.

摘要： A plasma generating method and apparatus which use plural high-frequency antennas 2 to generate inductively coupled plasma, and a plasma processing apparatus using the apparatus. The antennas 2 are identical to one another. Application of a high-frequency electric power to the antennas 2 is performed from a high-frequency power source 4 which is disposed commonly to the antennas 2, through one matching circuit 5 and one busbar 3. The busbar 3 is partitioned into sections the number of which is equal to that of the antennas, while setting a portion which is connected to the matching circuit 5, as a reference. One-end portions of the antennas are connected to corresponding sections 31, 32, 33 through power supplying lines 311, 321, 331. The other end portions of the antennas are grounded. The impedances of the sections of the busbar, and those of the power supplying lines are adjusted so that same currents flow through the antennas, and a same voltage is applied to the antennas. Therefore, the inductively coupled plasma is generated while uniformalizing high-frequency electric powers supplied to the antennas 2.
