- the antenna 40 generates inductively coupled plasma within the processing chamber 11.
- the antenna 40 is arranged within the surrounding space (antenna accommodation space) 33.
- at least a portion of antenna 40 is housed in partially open space 34 .

- the insertion member 45 is inserted into the through hole 22 provided in the outer cover 20 and connected to the antenna 40.
- the insertion member 45 is a part of the antenna 40. That is, in this embodiment, when the antenna 40 is attached to the plasma processing apparatus 1, a part of the antenna 40 is located within the surrounding space 33, and the remaining part is continuously penetrated from the part located within the surrounding space 33. It extends through the hole 22 to the outside environment, with the end of the antenna 40 exposed to the outside environment. Thereby, the number of parts of the plasma processing apparatus 1 can be reduced.
- the antenna 40 has, for example, a shape in which the vicinity of both ends of a cylindrical conductor is bent, and includes an elongated part 41 (see FIG.
- the insertion member 45 may be located in a region between the two parts. However, the insertion member 45 may be a member different from the antenna 40.
- the holding part 50 holds the insertion member 45 so that the insertion member 45 can be displaced while airtightly sealing the surrounding space 33 from the external environment. Further, the holding portion 50 may have insulation properties, and in this case, the insertion member 45 and the outer cover 20 can be electrically insulated from each other. In the example shown in FIG. 1, holding portions 50 are shown at two locations. Regarding the detailed constituent elements of the holding part 50, which will be explained below, in FIG. It may have a configuration.

- the holding part 50 is not particularly limited in its specific structure as long as it can hold the insertion member 45 so that the insertion member 45 can slide while keeping the inside of the housing 10 in an airtight state.
- the holding part 50 is not limited to the above example, and may be configured using, for example, a flexible member or a member having an expandable structure.

The other end of the bellows may be airtightly connected to the outer peripheral surface of the insertion member 45. By expanding and contracting the bellows following the displacement of the antenna 40, the insertion member 45 can be displaced while airtightly sealing the surrounding space 33 from the external environment.
- the insertion member 45 is difficult to follow the deformation of the outer cover 20. This is because the deflection of the outer cover 20 is offset by the expansion and contraction of the bellows. As a result, even when the outer cover 20 is bent, the position of the antenna 40 can be easily maintained.
- one end of the bellows is airtightly connected to the surface of the outer cover 20 facing the external environment, and the other end of the bellows is connected to the outer periphery of the portion of the insertion member 45 that protrudes from the through hole 22 toward the external environment. It may also be connected hermetically to the surface. Even in such a configuration example, the same effects as described above can be achieved.

- the surface roughness of the sliding contact portion 46 may be smaller than the surface roughness of a portion of the antenna 40 (for example, the elongated portion 41) disposed within the surrounding space 33. This improves the adhesion at the contact portion between the holding portion 50 and the sliding contact portion 46, for example, at the portion where the vacuum seal member 53 and the sliding contact portion 46 contact each other. As a result, the airtightness of the housing 10 is maintained well.
- the position adjustment mechanism 60 adjusts the position of the antenna 40 by displacing the insertion member 45 with the outer cover 20 attached to the housing 10.

- the high frequency power supply 71 outputs high frequency (for example, 13.56 MHz) power.
- high frequency for example, 13.56 MHz
- the matching box 72 improves power transmission efficiency from the high frequency power source 71 to the load by matching the impedance of the load to the high frequency power source 71 with the power source impedance.
- the plasma processing apparatus 1 maintains the electrical connection between the power supply unit 70 and the antenna 40 and the electrical connection between the antenna 40 and the variable capacitor 73 even if the height (position) of the antenna 40 changes due to the position adjustment mechanism 60. It may have a configuration that allows the connection to be maintained. For example, the contact point between the wiring 74 from the power supply section 70 and the insertion member 45 and the contact point between the wiring 79 from the antenna 40 to the variable capacitor 73 and the insertion member 45 are slidable with respect to the insertion member 45. good.

- the chiller 75 circulates a cooling medium (for example, cooling water) inside the antenna 40.
- a cooling medium for example, cooling water
- a Cu tube internal piping
- the chiller 75 is connected to both ends of the Cu tube by tubes 76. Cooling water supplied from the chiller 75 to one end of the Cu tube via the tube 76 flows through the Cu tube and returns from the other end of the Cu tube to the chiller 75 via the tube 76, thereby cooling the antenna 40.
- the plasma processing apparatus 1 may have a configuration in which the connection between the chiller 75 and the insertion member 45 can be maintained even if the height (position) of the antenna 40 changes by the position adjustment mechanism 60.
- the specific aspect of the configuration is not particularly limited. At least a portion of the tube 76 connecting the chiller 75 and the Cu tube may have flexibility. In this case, even if the position of the end of the Cu tube changes due to a change in the height of the antenna 40 by the position adjustment mechanism 60, the connection between the chiller 75 and the Cu tube is maintained.

- the control unit 65 may operate the drive unit 62 to adjust the position of the antenna 40 within a range where the distance between the antenna 40 and the surface of the inner cover 30 facing the enclosed space 33 is 1 mm or more. By controlling the position of the antenna 40 within the above range by the control unit 65, the antenna 40 is prevented from coming into contact with the inner cover 30. Therefore, damage to the inner cover 30 and plasma abnormalities caused by the contact can be prevented.
- the distance between the surface of the end of the elongated portion 41 on the first end 41a side and the inner cover 30 is the first distance d1.
- the distance between the surface of the end of the antenna 40 on the second end 41b side and the inner cover 30 is defined as a second distance d2.
