摘要： The present invention aims to provide a plasma generator capable of creating a spatially uniform distribution of high-density plasma. This object is achieved by the following construction. Multiple antennas are located on the sidewall of a vacuum chamber, and a RF power source is connected to three or four antennas in parallel via a plate-shaped conductor. The length of the conductor of each antenna is shorter than the quarter wavelength of the induction electromagnetic wave generated within the vacuum chamber. Setting the length of the conductor of the antenna in such a manner prevents the occurrence of a standing wave and thereby maintains the uniformity of the plasma within the vacuum chamber. In addition, the plate-shaped conductor improves the heat-releasing efficiency, which also contributes to the suppression of the impedance.

Furthermore, the occurrence of abnormal discharge is suppressed to stabilize a high-density plasma by reducing the inductance of the antenna and covering the antenna conductor with an insulator.

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 processing device has: a metallic vacuum chamber; an antenna-placing section in which a radio-frequency antenna is placed inside a through-hole (hollow space) provided in an upper wall of the vacuum chamber; and a dielectric separating plate covering the entire inner surface of the upper wall. In this plasma processing device, the entire inner surface side of the upper wall is covered with the separating plate so that surfaces in different level otherwise formed when a smaller separating plate is used is not formed between the inner surface and the separating plate. Therefore, the generation of particles caused by the formation of adhered materials on the surfaces in different level is prevented.
