If there is a chemical formula in this case, please disclose the chemical formula that best shows the characteristics of the invention: fe 0 VI. Description of the invention: [Technical field of the invention] The present invention relates to an inductive light-weight type that can be used for surface treatment of substrates and the like. Plasma processing unit. [Prior Art] Conventionally, a plasma processing apparatus has been used to perform a film forming process for forming a thin film on a substrate or to perform a dicing process on a substrate. The plasma processing apparatus includes a capacitive coupling type plasma processing apparatus that generates plasma by applying electromagnetic % generated by applying a high-frequency voltage between the electrodes, or by circulating a high frequency in a south frequency antenna (coil) An inductively coupled plasma processing apparatus that generates an electric field by an electromagnetic field generated by a current. #中, Capacitive-coupled plasma processing equipment has a lower cost than the inductive coupling type, and the inductively coupled plasma processing device can generate a higher density plasma than the capacitive coupling type. The ability to make film speed is fast. In the inductively coupled plasma processing apparatus, most of the external antennas in which the high frequency antenna for generating the induced electromagnetic field is disposed outside the vacuum vessel are used. However, in recent years, the large area of the substrate to be processed and the film formed thereon has been increasing, and the vacuum container has been enlarged, and the wall portion of the vacuum container is based on the relationship between the difference between the inside and the outside. Thicken. The intensity of the induced electromagnetic field introduced into the vacuum vessel by the crucible becomes small, and there is a problem that the density of the generated plasma is lowered. On the other hand, in the inductively coupled plasma device described in Patent Document 1, the internal antenna is used to set the high-frequency antenna inside the vacuum container, and the internal antenna method does not depend on the vacuum container. Since the thickness of the wall portion can easily increase the plasma density, it is suitable for a large area of the substrate to be processed and the thin film. When s is installed in the inside of the vacuum container, the problem that the loading and maintenance inspection becomes less easy will occur. Usually, the high-frequency antenna is used to stop the heating of the high-frequency current flowing through the antenna conductor and thus the rise of the resistance, and the tubular conductor tube having a cavity inside is used. By 201212728, the refrigerant flows through the inside of the conductor tube. , to enter the m ancient - Ding antenna conductor cooling. Therefore, the connection between the true Χ························································· 4. The connection of the discharge port becomes more complicated. * The setting or removal of the inter-frequency antenna becomes more difficult. % 7 c straight and 3⁄4 In addition, there will be a problem that the high-frequency antenna is directly ^^, and the road is lost in the plasma. In the electro-convergence processing device that senses H, the high-frequency antenna and the electric current will be the self-bias voltage of the factory DC. In the external antenna mode, the ion system accelerated by the self-bias voltage is obscured by the wall, but in the internal antenna mode, the antenna conductor is Sputtering. In order to prevent this, in the invention described in Patent Document 2, the surface of the conductor of the area frequency antenna is used by the non-prefecture, and it is necessary to use the Taman or the sputter which is not easily sputtered by the antenna conductor. A dielectric f (insulator) pipe made of quartz or the like is covered. However, when the dielectric tube is processed in accordance with the shape of the antenna, it is necessary to have a high degree of technology and a high manufacturing cost. Further, as described above, when the cooling of the antenna conductor is performed by circulating the refrigerant inside the conductor tube, the dielectric tube member may directly reach several hundreds without being sufficiently cooled. c is a very high temperature situation. Therefore, the dielectric tube becomes destructive due to thermal stress and the antenna conductor is not sufficiently cooled due to the heat propagation from the dielectric tube member, so that the impedance of the antenna conductor rises and the plasma cannot be stably supplied. . (Patent Document 1) (Patent Document 1) Japanese Laid-Open Patent Publication No. Hei No. Hei. No. Hei. No. 035697 (Patent Document 2). The problem to be solved by the present invention is to provide a plasma processing apparatus which is easy to maintain and inspect and which can stably supply an internal antenna of the plasma. (Means for Solving the Problem) The plasma processing apparatus of the present invention, which has been developed to solve the above problems, includes: a) a vacuum container; b) a system that protrudes more inward than an inner wall of the vacuum container And a dielectric frame for disposing the high frequency antenna in a non-contact manner with the high frequency antenna by isolating the mist surrounding the vacuum container. In the electric processing apparatus of the present invention, the internal antenna type radio-frequency antenna can be prevented from being plated by the dielectric material frame. This frame system does not need to be formed in the shape of a high-frequency antenna as in the case of a dielectric tube member, and can be formed into a shape which is relatively easy to manufacture, so that the manufacturing cost can be suppressed to be low. In addition, it has the advantage that the same shape can be used for any antenna shape. Further, by making the high-frequency antenna and the casing non-contact, it is possible to prevent the temperature of the casing 9 from directly propagating in the casing by the heat generated by the high-frequency current flowing through the antenna conductor. The plasma processing apparatus of the present invention has an antenna insertion opening that communicates with the outside of the vacuum container provided inside the dielectric housing of the inner container, and inserts the antenna into the opening. A closed cover 201212728 is preferred. In this way, since the antenna can be inserted through the antenna, the maintenance inspection of the device becomes easier. ^ 叫'' is preferably mounted on the aforementioned cover member with the aforementioned high-frequency antenna. Thereby, the high-frequency antenna can be easily taken out by attaching and detaching the cover member. Preferably, the interior of the dielectric frame is filled with an inert gas, or is vacuumed or filled with a solid dielectric. Thereby, unnecessary discharge can be prevented from occurring in the dielectric frame. Preferably, the high-frequency antenna is constituted by an official conductor that can circulate a cooling medium therein. Thereby, it is possible to suppress the heating of the antenna conductor due to the high-frequency current flowing, and thus the rise of the impedance. Further, when the refrigerant is an inert gas, in the electric consumer processing apparatus of the present invention, it is possible to include a blade edge s provided in a wall of a portion of the conductor tube housed in the dielectric casing. The emulsion of the sputum passes through the hole; and the gas is discharged from the gas through the hole to the aforementioned squirrel _ _ &; 疋 疋 前述 前述 前述 前述 前述 前述 前述 前述 前述 前述 前述 前述 前述 惰性 惰性 惰性 惰性 惰性 惰性 惰性 惰性 惰性 惰性 惰性 惰性 惰性 惰性 惰性 惰性 惰性The structure of the external gas discharge hole. In this case, the dielectric body can be filled with an inert gas to prevent unnecessary discharge in the dielectric frame, and the conductor can be prevented from rising by cooling the conductor tube from inside and outside. It is possible to supply the electro-hydraulic water in a stable manner. It is also possible to prevent the damage of the dielectric frame due to thermal stress by simultaneously cooling the dielectric frame. A linear conductor including a U-shape or a 3-shape in a part of the shape can be used in the just-described antenna system. The U-shaped or U-shaped guide system has two straight portions arranged in parallel. If the current flows through the conductor, the electric catching direction to the two straight portions is different from 1 to 80. Thereby, the direction of the magnetic lines of force generated by the flow of electricity to the respective straight portions 6 201212728 is uniform in the region between the two straight portions. Therefore, the strength of the magnetic field and the plasma density in the region can be increased. The plasma processing apparatus of the present invention may comprise a plurality of the aforementioned high frequency antennas and a dielectric frame. Thereby, the plasma can be formed without missing portions in the vacuum container to improve the uniformity of the plasma density. (Effect of the Invention) According to the electric paddle processing device of the present invention, the radio-frequency antenna 'provided in the internal space of the vacuum container is surrounded by a dielectric frame that is not in contact with the radio-frequency antenna. Depending on the shape of the HF antenna, the high frequency antenna conductor can be prevented from being sputtered. Since the dielectric frame has a simpler shape than the dielectric tube, it is easy to manufacture and can suppress the manufacturing cost to be low. Further, the maintenance of the radio-frequency antenna can be easily performed by providing an antenna insertion opening that connects the dielectric casing to the outside of the vacuum vessel and a cover that closes the antenna insertion opening. Further, by circulating the inert gas in the dielectric casing, the inert gas is circulated, thereby preventing unnecessary discharge in the dielectric casing and preventing the temperature rise of the antenna conductor. Thereby, the plasma can be supplied stably. [Embodiment] A plasma processing apparatus of the present invention will be described using Figs. 1 to 8 .

The manner of the edge of the upper opening m 1 is taken by the female skirt on the upper wall. Further, a vacuum seal 26' is provided between the flange portion 2A and the upper wall 111, and between the flange portion 211 and the cover member 22 so that gas leakage does not occur between them. Among them, as the dielectric material constituting the frame 21, a metal oxide, a nitride, a carbide fluoride or the like can be used. Further, among these materials, cerium alumina, cerium oxide, oxidized particles, cerium nitride, and cerium lanthanum can be suitably used. A directional antenna 23 formed of a chevron conductor is disposed inside the dielectric housing 21, and a communication line for ensuring airtightness and electrical insulation between the HF antenna 23 and the cover member 22 is ensured. (feedthr〇ugh) 24, the vicinity of both ends of the square-shaped conductor is fixed to the cover member 22. The _ terminal of the mouth-shaped conductor is connected to the high-frequency power supply, and the other end is grounded. The square-shaped conductor has a tubular shape, and a second gas introduction port 231 for introducing an inert gas into the tube is provided at both ends of f. Further, the outer side of the pipe wall is formed on the outer side of the pipe wall, that is, the side opposite to the dielectric wall portion of the dielectric casing 21, and the inert gas in the pipe is sent out to the dielectric casing 21. Gas passes through the aperture 232. The lid member 22 is provided with a second gas discharge port 25 for discharging the residual gas (two gases) other than the inert gas or the inert gas in the dielectric housing 21 to the outside of the dielectric housing.

First, the substrate S is carried into the vacuum container n from the substrate carry-in/out port 15 and placed on the substrate: holding portion 12. Next, the 暮(4)(1) is placed on the base body, and the direct opening and closing of the body melon 15 is closed. The vacuum is used to discharge the airwork u in the vacuum container 11 from the first gas discharge port. On the other hand, the inert gas is introduced into the dielectric casing 21 through the conductor tube and the 9201212728 gas passage hole 232 by the second contact. Thereby, the air in the dielectric frame 21 is replaced with an inert gas, and the air and the remaining inert gas are discharged from the second gas discharge port 25 to the outside of the dielectric f frame 21. Then, the inert gas is supplied to the plasma generating gas and the material gas, and the high frequency power is supplied to the high frequency antenna 23. The induction electromagnetic field is generated around the high frequency antenna 23 by the input of the high frequency power. . The induced electromagnetic field is introduced into the vacuum vessel 11 through the wall portion of the dielectric casing 21, and the plasma generating gas is ionized. This produces plasma. The raw material gas system introduced into the vacuum vessel 11 together with the gas for generating plasma is decomposed by the plasma and deposited on the substrate 5. While the high-frequency antenna 23 is being supplied with the high-frequency power, the inert gas system is blown into the dielectric wall portion of the dielectric casing 21 through the gas passage hole 232 through the conductor tube. As a result, the inert gas system functions as a refrigerant that suppresses the increase in the temperature of the high-frequency days, the line 23 & the dielectric wall portion generated by the supply of the high-frequency power. In the plasma processing apparatus 1 of the present embodiment, since the high-frequency antenna 23 is disposed in the dielectric housing 21 protruding from the inside of the vacuum container 11, the external antenna can be formed in the real actuator ii. In the case of a stronger induced electromagnetic field. In addition, since the wall portion of the dielectric frame body 21 is separated by the ergonomics, the high frequency antenna (2) is performed by the plasma to prevent the life of the HF antenna 23 from becoming short. Or preventing the material mixed into the high frequency antenna 23 in the film or the processing substrate from becoming an impurity. Further, the second gas introduction port 231 passes through the conductor tube and the gas passes through the hole 10 of 127, 2012, and the inert gas is introduced into the dielectric frame body 21, whereby the dielectric frame body 21 is filled with the h-shaped rolled body. Therefore, unnecessary discharge can be prevented from occurring, and the high frequency antenna 23 can be cooled by using an inert gas as a refrigerant. As described above, in the plasma processing apparatus 1 of the present embodiment, the prevention measures for discharging can be performed by one gas supply & ', and the cooling measures of the high-frequency antenna 23 and the dielectric housing 21 are performed. Both sides can therefore simplify the device. An experiment of generating plasma using the plasma processing apparatus 1 of the present embodiment was carried out. In the present experiment, a mixed gas of argon and hydrogen (plasma generating gas) is introduced into the vacuum vessel 11 by the i-th gas introduction port 14 so that the pressure becomes 1 Pa, and the second gas introduction port 231 is used. 2.5 liters of nitrogen (inert gas) was introduced into the conductor tube and the dielectric frame 21. Then, the high frequency antenna 23 is supplied with a frequency ι3·56 ΜΗζ and a high frequency power of lkw is output. After a sufficient elapse of time, the measurement was performed below the bottom i〇cm of the dielectric frame 21, and as a result, it was confirmed that a plasma having a density h 2xl 〇 llcm_3 was formed. The electric t density is roughly inversely proportional to (4) of the bottom of the 35-word body. In addition, when the output of the frequency power is changed within the range of 1 to 3 kf, the plasma density and the output of the high-frequency power are substantially positive. Change by comparison (Fig. 2). Both the high-frequency antenna 23 and the dielectric frame 21 are cooled by using an inert gas, and the temperature can be maintained at 8 (rc or less). (Example 2) In the plasma processing apparatus 1 of the first embodiment, As shown in Fig. 3, the second gas discharge port 25 and the second gas introduction port 231 are connected by a connection pipe π, and a pump and a heat exchanger 28 can be provided between the two. The connected second gas introduction port 231 and the connection f Μ are interposed between the two 201212728 insulators, or the Lianzheng camp 27 is formed as an insulation system, thereby making electrical insulation. #由如此此0, 疋In this configuration, the inert gas discharged from the second gas discharge port 25 is cooled by the s ^ parent changer 28, and can be introduced again into the second gas introduction port 231, so that the inert gas can be circulated because of the taste. In addition, in the case of giving priority to economics, the atmosphere can be circulated as a cooling gas. (Embodiment 3) In the electropolymerization processing apparatus 10 of the first embodiment, It is also possible to install the opening 彳1 iii of the vacuum capacity 11 from the lower side. The dielectric housing 21 is attached to the cover member 22 so as to cover the opening portion 1111 from the upper side (Fig. 4 (4)). At this time, the flange portion 2 of the dielectric housing 21 is fixed to the lower surface of the upper wall 111. The cover member 22 is fixed to the upper surface of the upper wall lu. Alternatively, the dielectric housing 21 may be attached to the lower surface of the upper wall U1 having no opening (Fig. 4(b)). At this time, the high frequency antenna 23 is attached. The upper wall is fixed to the upper wall. Further, the cover portion is not required. (Example 4) A vacuum pump can be used to evacuate the gas from the second gas discharge port 25 by using a vacuum pump, thereby forming a vacuum. Instead of filling with an inert gas (Fig. 5(a)). At this time, although the gas passage hole 232 is not provided, in order to cool the high frequency antenna 23, the high frequency antenna 23 is formed into a conductor regulation in the tube. It is preferable to supply a refrigerant such as a cooling gas or a cooling water. By this configuration, as in the case of using an inert gas, discharge in the dielectric housing 21 can be prevented, and the high-frequency antenna 23 and the dielectric frame can be The heat insulation between the wall portions of the body 21 can prevent the temperature of the dielectric frame 21 from rising. 12 201212728 Or, The dielectric housing 21 may be filled with a solid dielectric material μ (Fig. 5(b)). The dielectric material 29 may be a block or a powder. The dielectric housing 21 is sealed in such a manner that air does not enter the gap of the powder. The material of the dielectric material 29 can be a resin such as polytetrafluoroethylene (PTFE) or polyetheretherketone (pEEK). A ceramic such as alumina or cerium oxide, etc. The dielectric material 29 prevents discharge in the dielectric housing 21. At this time, the high frequency antenna 23 is formed so that the high frequency antenna 23 is cooled. It is preferable to circulate a refrigerant such as a cooling gas or a cooling water in the pipe by conductor control. (Embodiment 5) An example of using a high-frequency antenna 23A having a different shape (Fig. 6) will be described. The plasma processing apparatus of the present embodiment has the same shape as the plasma processing apparatus 1 of the first embodiment except for the shape of the high-frequency antenna 23a and the sizes of the opening 1111A, the dielectric housing 21A, and the lid member 22A. Composition. The high-frequency antenna 23A has two legs 3 ι which are extended downward by the cover member 22, and have a U-shape, and the surface formed by the u-shape is parallel to the bottom surface of the frame 21 (the high-frequency antenna 23A faces the vacuum container). The U-shaped portion 312 is arranged such that the insertion direction of u is vertical; and the middle end of the U-shaped portion 312 is connected to one of the legs 311, and the other end of the u-shaped portion 312 and the other end of the foot 311 are Two curved portions 313 that are connected to each other. In the present embodiment, the lengths of the two straight portions (the first straight portion 3121 and the second straight portion 3122) of the U-shaped portion 312 are set to 1 〇cm, and the first straight portion 3121 and the second straight portion are formed. The spacing between the conductors in 3122 is set to 3 cm. Here, the term "interval between conductors" refers to the distance between the inner sides of two conductors 13 201212728 arranged in parallel. The dielectric housing 2U is shaped to match the shape of the high frequency antenna 23A, and the inner short side is formed to be 6 cm longer than the dielectric housing 21 of the i-th embodiment. The depth and the length of the long side inside the dielectric frame 21A are the same as those of the dielectric frame 2A of the first embodiment. The size of the opening portion A and the cover member 22A also match the short side of the inside of the dielectric housing 21A, and the direction of the short side is formed larger than that of the first embodiment. In the high-frequency antenna 23A having the shape of the sixth embodiment, in the i-th straight portion 3121 and the second straight portion 3122 which are arranged in parallel with the bottom surface of the casing 21A, the high-frequency currents flow in opposite directions to each other, so the frame is Immediately below the body 2U, the vertical component of the magnetic field formed by the current flowing through the first straight portion 3121 and the vertical component of the magnetic field formed by the current flowing through the second straight portion 3丨22 are By vibrating in the same phase, the intensity of the magnetic field in the lower portion of the frame 2 ^ A can be formed to be about 2 times as large as in the fourth to fourth embodiments, so that the discharge plasma can be generated with a small high-frequency power, and The discharge plasma can be stabilized even in a gas pressure region of, for example, less than 5 Pa, which is less likely to cause discharge. In the plasma processing apparatus of this embodiment, the experiment was conducted under the same conditions as in the first embodiment. In other words, a mixed gas of argon and hydrogen is introduced into the vacuum vessel while the pressure becomes 1 Pa, and 2.5 liters of nitrogen gas per minute is introduced into the conductor tube and the dielectric frame by the second gas introduction port 231. In the body 21, horse frequency power of 56 MHz and lkw is supplied to the high-frequency antenna 23A. After a sufficient elapse of time, the measurement was performed below the bottom of the dielectric frame 21, and the plasma density was 18 χ 1 〇 11 ^ 3 compared with the first embodiment (1.2 x 1 (Tcm - 3 )). In the present embodiment, the U-shaped portion is described as an example, and the U-shaped portion 312 can be replaced with a word in the same manner as in the first to fourth embodiments, and can be replaced with The S-shaped portion 312 is shown in Fig. 7.
