During the process of plasma treatment, the wafer is subjected to heat from the electric ferry to make the temperature Rising. When the temperature of the wafer rises, it changes the radical distribution on the wafer, and the reaction rate of the chemical reaction at the wafer changes. Therefore, in order to obtain the desired result in the plasma processing In order to control the temperature of the wafer itself, in recent years The seat is easy to have electric heating inside The refrigerant and the refrigerant flow path. The % heat heater heats the crystal seat, and the refrigerant flowing through the refrigerant flow path cools the crystal seat by transferring the heat of the crystal seat to the outside.

Therefore, the refrigerant flow path can be constantly circulated with refrigerant in the substrate processing device, and the electric heater can be heated to properly adjust the crystal as needed. For example, in the substrate processing apparatus, since the refrigerant flow path often flows through the refrigerant flow path, the electric heater is heated to raise the temperature of the crystal holder. At this time, a part of the heat from the electric heater is transmitted to the outside of the crystal seat through the refrigerant flowing through the refrigerant flow path, causing the temperature of the crystal holder to rise, and the progress of the wafer temperature rises.

The mounting surface of the substrate to which the specific treatment is applied is disposed, and the mounting surface, the heating unit, and the refrigerant chamber are sequentially disposed from above to allow the refrigerant to flow through the refrigerant flow path and the refrigerant chamber; The gas layer forming apparatus is configured to allow a gas to flow into the refrigerant chamber when the heating unit generates heat and the flow of the refrigerant stops, so that a gas layer is formed in the upper portion of the refrigerant chamber. The temperature control system of the substrate mounting table of the first aspect of the invention is the temperature control system of claim 9 wherein the gas layer forming device has a heating device for heating the gas. The heated high temperature gas forms the gas layer. In order to achieve the above object, the temperature control system of the board mounting table of the nth aspect of the patent application system has a heating unit, a refrigerant flow path, and a refrigerant chamber connected to the refrigerant flow path in the substrate mounting table, and is formed at the top.

According to the temperature control method of the substrate stage of the fifth application of the patent application, the pressurized high temperature gas system forming the gas layer is composed of the vapor of the refrigerant. The heat that is removed by the substrate stage causes the temperature to decrease, and the vapor is condensed to become a refrigerant, and is mixed with the refrigerant previously present in the refrigerant flow path. Therefore, since the temperature of the substrate does not need to be recovered, the procedure of the operator or the like can be eliminated, and the concentration of the refrigerant or the like does not change, so that the cooling performance change by the refrigerant can be prevented. According to the temperature control method of the substrate stage of the sixth aspect of the patent application, since the gas layer is formed by heating the refrigerant in the refrigerant chamber to the vapor of the refrigerant generated by the gas, it is not necessary to inject steam or the like from the outside. In addition, the heat is removed by the substrate mounting table, so that the vapor whose temperature is lowered will be condensed and returned to the original refrigerant. Therefore, after the substrate temperature rises, it is not necessary to recover the treatment gas of the refrigerant, and the procedure of the operator or the like can be omitted, and the concentration of the refrigerant or the like does not change, so that the cooling performance change by the refrigerant can be prevented.

The shower head 13 has a buffer chamber 20 therein and a plurality of gas holes 21 that communicate with the buffer chamber 20 and the processing space S. The processing gas is supplied from the external processing gas supply means (not shown) to the buffer chamber 20, and the supplied processing gas is introduced into the processing space S via the plurality of gas holes 21. Since the substrate processing apparatus 10 applies high frequency electric power to the processing space S, the processing gas introduced into the processing space S can be excited to generate plasma. Then, the wafer W is subjected to a plasma etching treatment using the cation or radical contained in the plasma generated as described above. In the plasma etching process, since the wafer W continues to receive heat from the plasma, the temperature of the crystal holder 12 rises. Thus, the substrate processing apparatus 10 is provided with a refrigerant circulation system to prevent the temperature of the crystal holder 12 from rising. The refrigerant circulation system includes a refrigerant chamber 16, a refrigerant flow passage 15, a refrigerant pipe 22 disposed outside the processing chamber 11 and connected to the refrigerant flow passage 15, and a refrigerant supply device 23 installed in the middle of the refrigerant pipe 22. In the refrigerant circulation system, the refrigerant chamber 16 is located at the uppermost portion of the refrigerant circulation system. The refrigerant supply device 23 has a function as a pressure feed pump, and the refrigerant is pressure-fed to the refrigerant chamber 16 in the direction of the arrow in the figure via the refrigerant pipe 22 and the refrigerant flow path 15. Further, the refrigerant supply device 23 has a function as a heat exchanger, and cools the refrigerant that has absorbed the heat of the crystal holder 12 to a high temperature, thereby lowering the temperature of the refrigerant to a lower temperature. Specifically, 201131642 is called a plasma rice. The temperature of the crystal holder 12 in the engraving process is maintained or lowered by a temperature of (for example, 10 C) to maintain the temperature of the refrigerant supplied from the refrigerant supply device 23 to the refrigerant to 16 at a lower temperature. Further, the refrigerant used in the embodiment is, for example, galdeZ (registered trademark) or FLUORINERT (registered trademark). When the wafer W is subjected to an electrical etching treatment in the substrate processing apparatus 10, heat from the heater unit 14 is used to raise the temperature of the wafer 12 to a suitable temperature for the plasma button processing. At this time, a part of the heat from the heater unit 14 is transmitted to the outside of the crystal holder 12 by the refrigerant flowing through the refrigerant flow path 15 or the refrigerant chamber 16, and the temperature of the crystal holder 12 is prevented from rising. In the present embodiment, in response to this, when the heater unit 14 generates heat to raise the temperature of the crystal holder 12, the flow of the refrigerant in the refrigerant flow path 15 or the refrigerant chamber 16 is stopped. Fig. 2 is a flow chart showing a method of controlling the temperature of the substrate stage of the embodiment. In Fig. 2, first, before the heater unit 14 generates heat, the refrigerant supply 襄t23 will pressurize the refrigerant to the refrigerant chamber 16, so that the refrigerant will circulate in the medium circulation system as shown by the arrow in the figure (Fig. 2). (Α)). Then, when the heater unit 14 generates heat, the refrigerant supply device 23 stops the pressure feed of the refrigerant (Fig. 2 (8)). Thereby, in the refrigerant circulation system, the flow of the refrigerant is stopped. In particular, when the flow of the refrigerant is stopped in the refrigerant chamber 16, the refrigerant in the refrigerant chamber 16 absorbs the portion of the heat from the heating element 14, but does not transfer the absorbed heat to the outside of the 12 201131642 crystal holder 12. Also, & Μ above, so from the twisting == two in the refrigerant room _ will not be in the media room 16 吝 4 people straw, because the cold will only absorb less material (four) 16 of the refrigerant from the heater unit two = 14 The result of the heat can increase the degree. 4 heat 1 is effectively used in the temperature of the crystal seat * When the temperature of the sun seat 12 rises to the electric junction temperature, the refrigerant #师w water (4) Han Li's suitable cold so that the refrigerant will be pressurized, the circulation system is as shown in the figure As shown by the middle arrow, the temperature of the crystal holder 12 can be maintained at a suitable temperature for the electrothermal water treatment. According to the temperature control method of the substrate stage of the present embodiment, since the flow of the refrigerant is stopped when the unit 14 generates heat, the portion of the hot summer of the unit 14 is not transmitted to the outside of the crystal holder 12 by the refrigerant. Thereby, the amount of electricity from the heater unit 14 can be efficiently used to increase the temperature of the crystal holder 12, so that the temperature of the wafer W can be rapidly increased and the heat energy loss can be reduced. > Further, since the flow of the refrigerant is stopped by the refrigerant supply device 23, the flow of the refrigerant is stopped. Therefore, it is not necessary to implement the temperature control method of the substrate stage of the present embodiment. A special device or the like is disposed in the refrigerant circulation system of 10, thereby preventing a substantial increase in cost. Further, in the temperature control method of FIG. 2, when the heater unit 14 13 201131642 generates heat and the flow of the refrigerant in the refrigerant single system is stopped, the refrigerant flow path 15 or the cold Wei f 22 may be directly recorded. The temperature of the refrigerant required at the temperature _) is high. The medium (for example, a high-temperature medium of 8 〇C) flows into the refrigerant chamber 16. Thereby, not only the heat from the heater unit 14 but also the heat of the mediator can be used to heat the crystal seat 12, and the heat from the heater material 14 can be reduced by the medium, but will be from the heater. The unit heat is more efficiently used for the temperature rise of the crystal holder 12, thereby rapidly increasing the temperature of the wafer W. In the temperature control method of the substrate stage of the present embodiment, the flow of the refrigerant is stopped in the refrigerant circulation system, but the flow of the refrigerant may be made slower than in the normal state, thereby reducing the transfer of the refrigerant to the crystal. The amount of heat external to the seat 12 causes the temperature of the wafer W to rise more rapidly than in the normal state. In the substrate processing apparatus 1A, the crystal holder 12 has the refrigerant chamber 16'. However, even if the crystal holder 12 does not have the refrigerant chamber 16, and only the refrigerant flow path 15 is provided, the heater unit 14 can be used when the heater unit 14 generates heat. The same effect is achieved by stopping the flow of the refrigerant in the refrigerant flow path 15. Next, a temperature control method and a temperature control system of the substrate stage according to the second embodiment of the present invention will be described. Fig. 3 is a cross-sectional view showing the structure of a substrate processing apparatus to which the temperature control method of the substrate stage of the embodiment is applied. The configuration and operation of the present embodiment are basically the same as those of the above-described third embodiment, and the description of the overlapping configuration and operation will be omitted. Hereinafter, the description will be made only for the different configurations and operations. In the above θ, the substrate processing apparatus 24 is in the middle of the refrigerant pipe 22 (the gas layer forming device, the dust groove μ system, the gas (for example, inert gas), and at a specific time: body inflow: medium Room: 622,: The media channel 15 is used to make the stored 嶋A (4) I must be defined as the pressure and temperature of the inert gas when it flows into the second-& In the above, the temperature is set to be the above j system = (3) == set, and is not shown in the middle. The temperature control of the substrate stage in the actual vibration mode is first described in the first step before the heater unit 14 is turned on. Person ΪίίΪί?3 will pressurize the refrigerant to the refrigerant chamber 16, so the refrigerant will be circulated as shown by the arrow in the figure: (Fig. 々(A)): When the heater unit 14 is hot, The refrigerant supply device 23 separates the pressure feed of the refrigerant. It will stop when you flow straight. At this time, in the medium (four) system, the refrigerant medium, the taxi, and the Z-slot 25 are flowed into the refrigerant chamber 经由6 through the refrigerant piping U and, *, and {the stored higher temperature and high pressure inert gas 26 ( Figure 4 (8)). The flow 26 has stopped because the flow of the refrigerant has stopped. And after the 16th, the refrigerant chamber 16 is located above the refrigerant recovery enthalpy, so that it stays in the upper portion of the refrigerant chamber. The receiver will have a reading layer 27 (gas layer) in the refrigerant chamber 因 due to the retained inert gas % (Fig. 4(C)). When the gas layer 27 201131642 is spread over the entire upper surface of the refrigerant chamber 16, so that the upper inner wall surface of the refrigerant chamber 16 is separated from the liquid level of the refrigerant of the refrigerant chamber 16, the pressurizing tank 25 stops flowing into the inert gas 26. At this time, since the gas layer 27 exists between the heater unit 14 and the refrigerant of the refrigerant chamber 16, the heater unit 14 is thermally isolated from the refrigerant of the refrigerant chamber 16. Thereby, the heat from the heater unit 14 is not absorbed by the refrigerant of the refrigerant chamber 16. As a result, the heat from the heater unit 14 can be efficiently used for the temperature rise of the crystal holder 12. Then, when the temperature of the crystal holder 12 rises to a suitable temperature for the plasma etching treatment, the refrigerant supply device 23 starts the pressure feed of the refrigerant again, so that the refrigerant circulates in the refrigerant circulation system as indicated by the arrow in the figure ( Figure 4 (D)). At this time, the inert gas 26 of the refrigerant chamber 16 is transferred to the outside of the refrigerant chamber 16 by the circulating refrigerant, causing the gas layer 27 to disappear. Thereby, the temperature adjustment of the crystal holder 12 is started by the circulating refrigerant to maintain the temperature of the crystal holder 12 at a suitable temperature for the plasma etching treatment. According to the temperature control method of the substrate stage of the embodiment, when the heater unit 14 generates heat and the flow of the refrigerant in the refrigerant circulation system is stopped, the gas layer 27 is formed in the upper portion of the refrigerant chamber 16. Since the gas layer 27 is present between the heater unit 14 and the refrigerant of the refrigerant chamber 16, the heater unit 14 is thermally isolated from the refrigerant of the refrigerant chamber 16, so that the heat from the heater unit 14 can be more efficiently The temperature used for the crystal holder 12 rises. In the temperature control method of the substrate mounting table according to the present embodiment, the gas layer 27 is formed by the relatively high-pressure, high-temperature inert gas 26 from 16 201131642, so that the heat of the heater alone is not strong. The heat of the gas layer 27 can be used to heat the crystal holder 12, and the heat from the heater unit U taken away by the gas layer 27 can be reduced, and the heat from the heating unit 14 can be more efficiently used in the crystal holder 12. The temperature rises, so that the temperature of the wafer W can be increased more rapidly. When the gas layer 27 is generated, 'in order to maintain the temperature of the gas layer 27 at a relatively high temperature, it is preferable to close the width of the refrigerant pipe 22 in the middle. The door 28 (see FIG. 3) is configured to re-pressurize the refrigerant chamber 16 and the like after the refrigerant chamber 16 and the refrigerant flow passage 15 are isolated from the outside. At this time, since the gas layer 27 is adiabatically compressed and the temperature rises, it is easy to The temperature of the gas layer 27 is maintained at a relatively high temperature. In the temperature control method of the substrate stage, the pressure tank 25 stores an inert gas, and the inert gas flows into the refrigerant chamber 16 to form a gas layer 27' in the stomach. Slot 25 can also be stored The refrigerant vapor at a higher pressure and a higher temperature (for example, 2 or more, and for example, 12 Å or more) is passed through the refrigerant chamber 16 to form a gas layer, thereby allowing a higher pressure and a higher temperature. The refrigerant vapor forms gas (4) 27. Then, the vapor of the refrigerant which is deprived of heat by the crystal holder 12 is condensed to become a refrigerant, and is mixed with the refrigerant which was previously present in the refrigerant chamber 16 or the refrigerant passage 15. After the temperature of the wafer w rises, since the steam of the refrigerant is not required, the operator's procedure can be eliminated, and the concentration of the refrigerant or the like changes, so that the cooling performance change caused by the refrigerant can be prevented. 17 201131642 When the gas layer 27 is present, the refrigerant of the refrigerant chamber 16 or other heaters (not shown) may be used to heat the refrigerant in the refrigerant chamber 16 to generate the refrigerant without flowing the inert gas 26 or the refrigerant vapor into the refrigerant chamber 16. The vapor is formed by the vapor of the refrigerant generated in the refrigerant chamber 16. In this case, it is not necessary to provide a means for flowing the inert gas 26 or the like into the refrigerant chamber 16 in the refrigerant circulation system ( The groove 25) can simplify the structure of the device. Further, since the vapor of the refrigerant whose temperature is lowered by the crystal holder 12 is condensed and returned to the original refrigerant, the refrigerant vapor can be caused to flow into the refrigerant chamber 16. In the following, the temperature control method and the temperature control system of the substrate stage according to the third embodiment of the present invention will be described. Fig. 5 is a view schematically showing the substrate processing to which the temperature control method of the substrate stage of the embodiment is applied. The configuration and operation of the present embodiment are basically the same as those of the above-described first embodiment, and the description of the overlapping configuration and operation will be omitted. Hereinafter, only the different configuration and operation will be described. The substrate processing apparatus 29 is provided with a heat-insulating particle tank in the middle of the refrigerant piping 22 on the cold side of the refrigerant circulation system. The heat-insulating particle tank 3G stores a large amount of refrigerant particles (4) (for example, a heat-resistant resin). The spherical heat insulating tube 22 and the α-shaped material I are supplied with a refrigerant through a refrigerant at a specific time point to make the stored majority of the insulating particles 31 to 16 streams. Here, the heat insulating particles 31 are set to a relatively high temperature (for example, 201131642 and 90 ° C or higher). Further, the adiabatic particle tank 30 has a heater (heating means, not shown) to maintain the stored heat insulating particles 31 at a relatively high temperature. Further, the substrate processing apparatus 29 has a heat insulating particle collector 32 in the middle of the refrigerant piping 22 on the downstream side of the refrigerant chamber 16 in the refrigerant circulation system. The adiabatic particle collector 32 is a space 33 having a specific volume inside, and a recovery net 34 disposed in the space 33. The recovery net 34 separates the refrigerant from the heat insulating particles 31 by filtering the refrigerant containing the plurality of heat insulating particles 31 flowing out of the refrigerant chamber 16 in the space 33. The separated majority of the adiabatic particles 31 are taken out from the adiabatic particle collector 32 together with the recovery net 34, and are again stored in the adiabatic particle tank 30. Fig. 6 is a flow chart showing a method of controlling the temperature of the substrate stage of the embodiment. In Fig. 6, first, before the heater unit 14 generates heat, since the refrigerant supply device 23 pressurizes the refrigerant to the refrigerant chamber 16, the refrigerant circulates in the refrigerant circulation system as indicated by the arrow in the figure (Fig. 6 (Fig. 6 A)). Next, when the heater unit 14 generates heat, the refrigerant supply device 23 stops the pressure feed of the refrigerant. Thereby, in the refrigerant circulation system, the flow of the refrigerant is stopped. At this time, the heat insulating particle tank 30 flows the stored higher temperature heat insulating particles 31 into the refrigerant chamber 16 via the refrigerant pipe 22 and the refrigerant flow path 15 (Fig. 6(B)). The heat insulating particles 31 which have flowed into the refrigerant chamber 16 have stopped due to the flow of the refrigerant, and their density is smaller than that of the refrigerant, so that they stay in the upper portion of the refrigerant chamber 16. Then, when the heat insulating particle layer 35 (heat insulating layer) is formed in the upper portion of the refrigerant chamber 16 due to the retained heat insulating particles 31 (Fig. 6(C)), the heat insulating particles 19 201131642 stop flowing into the heat insulating particles 31. At this time, since the adiabatic particle layer 35 exists between the heater unit 14 and the refrigerant in the refrigerant chamber 16, the heater unit 14 is heated from the refrigerant in the refrigerant chamber. Thereby, the heat from the heater unit 14 is not absorbed by the refrigerant of the refrigerant chamber 16. As a result, the temperature from the heating * heat can be efficiently used to raise the temperature of the crystal holder 12. Then, when the temperature of the crystal holder 12 rises to a suitable temperature for the electric etch process, the refrigerant supply device 23 starts the pressure feed of the refrigerant again, so that the refrigerant is circulated in the refrigerant circulation system as indicated by the arrow in the figure.裱 (Fig. 6(D)). Thereby, the heat insulating particles 31 of the refrigerant chamber 16 are circulated to the refrigerant, and (4) are transferred to the refrigerant chamber 16, and the annihilated particle layer 35 disappears. Thereby, the temperature adjustment of the crystal holder η is started by the circulating refrigerant to maintain the temperature of the crystal holder 12 at the electric secret temperature. At this time, the hot particle collector 32 is collected in the space magic recovery net 34 to be recovered by the refrigerant to be transferred to the refrigerant chamber 16 = most of the heat insulating particles 31. . According to the temperature control method of the substrate stage according to the embodiment, when the heat exchanger unit το 14 generates heat and the flow of the refrigerant in the refrigerant circulation system stops, the heat insulating particle layer % is formed in the upper portion of the refrigerant chamber 16. The heat insulating particle layer 35 is present between the heater unit 14 and the refrigerant of the refrigerant 16 to thermally isolate the heater unit 14 from the refrigerant chamber to the medium, so that the heat from the heater unit 14 can be further increased. The temperature used for the crystal holder 12 is increased efficiently. In the temperature control method of the substrate stage of the above-described embodiment, the heat insulating particle layer 35 is formed by the relatively high temperature heat insulating particles 31 from '201131642, so that not only the heat from the heater unit 14, but also the heat from the heater unit 14 The crystal holder 12 can also be heated by the heat of the insulating particle layer 35, and the heat from the heater unit 14 taken away by the insulating particle layer 35 can be reduced, and the heat from the heating unit 14 can be used more efficiently. The temperature rise of the crystal holder 12 can increase the temperature of the wafer W more quickly. Further, the substrate to which the plasma treatment is applied in the above embodiments is not limited to the wafer for semiconductor elements, and may include an LCD. Various substrates, masks, CD substrates, printed boards, etc. used in FPD (Flat Panel Display), etc. (Liquid Crystal Display), etc. [Brief Description] FIG. 1 is a schematic view showing a substrate to which the embodiment of the present invention is applied.
