[0025] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] It should be noted that in this article, the terms "include", "comprise", "have" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or terminal device including a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or terminal device. Without further limitation, the elements defined by the statement "include..." or "comprise..." do not exclude the existence of additional elements in the process, method, article or terminal device including the said elements.

[0027] It should be noted that the accompanying drawings are in very simplified forms and use non-precise ratios. In the present utility model, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. They are only used to conveniently and clearly assist in explaining the purpose of an embodiment of the present utility model.

[0028] Figure 1 FIG. 4 is a partial cross-sectional view of a reaction chamber 10 for plasma processing in an inductively coupled plasma (ICP) reaction device. The reaction chamber 10 includes a generally cylindrical inner liner 11 made of a metallic material. Inside the inner liner 11 is a space for performing plasma reactions, including a pedestal for supporting a substrate. Above the inner liner 11 is provided an insulating window 12, and above the insulating window 12 is provided a coil. The radio frequency energy of the coil passes through the insulating window 12 and acts on the gas above the substrate to generate plasma. A sealing ring 13 is also provided between the insulating window 12 and the inner liner 11 to achieve the sealing between the insulating window 12 and the inner liner 11. Since the weight of the insulating window 12 is relatively large, a jig is required for installation and removal. In the prior art, the installation accuracy of the jig for installing the insulating window 12 is not high, and it is impossible to ensure the concentric installation of the insulating window 12 and the inner liner 11. When the insulating window 12 is installed on the top of the inner liner 11, a certain offset will occur. At the same time, when the existing jig installs the insulating window 12, the insulating window 12 needs to be lifted and moved multiple times to align with the inner liner 11. During the process of lifting and moving the insulating window 12 multiple times, the sealing ring 13 below the insulating window 12 will be worn, so the sealing ring 13 needs to be frequently replaced, increasing the manufacturing cost; if the sealing ring 13 is not replaced in time, it may also cause the leakage of plasma.

[0029] In view of the above defects, this embodiment provides a jig 100 for disassembling and assembling the insulating window 12 in an inductively coupled plasma reaction device, as Figure 1 and Figure 2As shown in the figure, the jig 100 includes: a main body ring 101, the inner diameter of which is greater than or equal to the outer diameter of the insulating window 12, so that the main body ring 101 can be sleeved on the circumferential outer side of the insulating window 12 during use; a positioning member 102, which is arranged at intervals on the lower surface of the main body ring 101 and corresponds to the preset positioning holes 14 at the top of the inner liner 11. By inserting the positioning member 102 into the corresponding positioning holes 14, the concentricity of the main body ring 101 and the inner liner 11 can be ensured; a plurality of fixed chucks 103, which have a fixed thickness extending radially along the main body ring 101 and are fixed at intervals on the inner side of the main body ring 101; at least one adjusting chuck 104, which is installed on the inner side of the main body ring 101 and can move radially along the main body ring 101; a lifting member 105, which is fixedly connected to the main body ring 101 and is used to lift the main body ring 101, and the adjusting chuck 104 can be arranged opposite to the fixed chuck 103; when moving the insulating window 12, the fixed chuck 103 and the adjusting chuck 104 respectively abut against the circumferential side walls of the insulating window 12, adjust the radial position of the adjusting chuck 104 on the main body ring 101, and further adjust the position of the insulating window 12 in the main body ring 101 to make the insulating window 12 concentric with the main body ring 101, and the fixed chuck 103 and the adjusting chuck 104 are fixed to the circumferential side walls of the insulating window 12 by friction, so that the insulating window 12 and the main body ring 101 remain relatively stationary.

[0030] As Figure 1 and Figure 2 shown in the figure, when installing the insulating window 12 using the jig 100 provided in this embodiment, the main body ring 101 and the insulating window 12 that remain relatively stationary are lifted simultaneously through the lifting member 105 and moved above the inner liner 11. Since the main body ring 101 can be concentrically arranged with the inner liner 11 through the positioning member 102, the positioning member 102 on the lower surface of the main body ring 101 is inserted into the corresponding positioning holes 14 to complete the concentric installation of the main body ring 101 and the inner liner 11, and thus the concentric installation of the insulating window 12 and the inner liner 11 is achieved at one time, reducing the wear on the sealing ring 13 below the insulating window 12. Among them, since three points can determine a circle, the number of the positioning members 102 is greater than or equal to 3 to ensure the concentric setting of the main body ring 101 and the inner liner 11.

[0031] Further, as Figure 1As shown, a clamping groove 121 is further provided on the circumferential side wall of the insulating window 12. The fixed clamping plug 103 and the adjusting clamping plug 104 can be embedded into the clamping groove 121 to improve the connection stability between the insulating window 12 and the main body ring 101. Among them, the sides of the fixed clamping plug 103 and the adjusting clamping plug 104 facing the insulating window 12 match the radian of the clamping groove 121. Specifically, the clamping groove 121 on the circumferential side wall of the insulating window 12 is a concave groove recessed towards the center of the circle. The sides of the fixed clamping plug 103 and the adjusting clamping plug 104 facing the insulating window 12 are convex arcs, and the radian of the arc is approximately equal to the radian of the groove, so that the fixed clamping plug 103 and the adjusting clamping plug 104 can be closely attached to the clamping groove 121. The clamping groove 121 provides a clamping fixing force and friction force to the fixed clamping plug 103 and the adjusting clamping plug 104, so that the insulating window 12 can be more stably fixed in the main body ring 101, effectively preventing the insulating window 12 from falling off the main body ring 101, and further improving the installation stability of the insulating window 12.

[0032] Specifically, as Figure 2 shown, in this embodiment, the shape of the main body ring 101 is a closed ring. The inner diameter of the main body ring 101 is larger than the outer diameter of the insulating window 12, so that the main body ring 101 can be arranged around the circumferential outer side of the insulating window 12. Two fixed clamping plugs 103 and two adjusting clamping plugs 104 are arranged along the circumference of the main body ring 101. The fixed clamping plug 103 has a fixed thickness extending radially along the main body ring 101, which can make the center of the insulating window 12 approximately located at the center position of the main body ring 101 when the insulating window 12 is arranged in the main body ring 101. Then, move the adjusting clamping plug 104 along the radial direction of the main body ring 101 to change the radial position of the adjusting clamping plug on the main body ring 101, that is, adjust the distance from the adjusting clamping plug 104 to the center of the main body ring 101, so that the center of the insulating window 12 coincides with the center of the main body ring 101, and then realize the concentric setting of the insulating window 12 and the main body ring 101. By setting the main body ring 101 as a closed ring, the fixed clamping plug 103 and the adjusting clamping plug 104 can be arranged at any position in the circumferential direction of the main body ring 101 to realize the radial adjustment of any circumferential position of the insulating window 12, and then ensure the concentric setting of the insulating window 12 and the main body ring 101.

[0033] Among them, as Figure 2As shown, the adjusting plug 104 includes a plug body 141 and a fastener 142; the first end of the fastener 142 is connected to the plug body 141, and the second end passes through the radial arrangement of the main ring 101. The plug body 141 is installed on the inner side of the main ring 101 or flexibly removed from the main ring 101 through the fastener 142 to ensure that the insulating window 12 can be installed in the main ring 101. Specifically, in the present embodiment, the fastener 142 is a second screw, and the plug body 141 is fixed on the main ring 101 by inserting the second screw into the mounting hole on the main ring 101 and rotating the second screw; when the insulating window 12 is installed in the main ring 101 and the position of the insulating window 12 in the main ring 101 needs to be adjusted, the second screw is rotated again to drive the plug body 141 to move back and forth radially along the main ring 101, and the extrusion force provided by the plug body 141 pushes the insulating window 12 to be displaced radially, thereby realizing the concentric adjustment of the insulating window 12 and the main ring 101.

[0034] Furthermore, the hanging member 105 includes at least one hanging rod 151, and a plurality of pull rings 152 are provided on the hanging rod 151. Both ends of each hanging rod 151 are fixedly connected to the main ring member 101, and two adjacent hanging rods 151 can also be arranged crosswise at a certain angle to improve the stability of the main ring member 101. By applying an upward pulling force to the pull ring 152, the main ring member 101 and the insulating window 12 are lifted up at the same time. In this embodiment, Figure 2 As shown, the hanging member 105 includes two hanging rods 151 , and the hanging rods 151 are arranged perpendicular to each other, which reduces the deformation and stress concentration of the main ring member 101 and enhances the structural stability of the main ring member 101 .

[0035] In another embodiment, if Figure 3 As shown, the lifting member 205 includes a lifting ring 251 concentric with the main ring 101, and a plurality of pull rings 253 are arranged on the lifting ring 251, and the pull ring 253 is fixedly connected to the lifting ring 251, and the lifting ring 251 is connected to the main ring 101 through a plurality of reinforcing rods 252, which can effectively enhance the structural stability between the lifting ring 251 and the main ring 101, especially when subjected to external loads or torque, it can help disperse the force, reduce local stress, and improve the rigidity and anti-deformation ability of the overall structure. At the same time, by setting the lifting ring 251 concentric with the main ring 101, the level of the main ring 101 and the insulating window 12 during the movement is also guaranteed, which effectively prevents the main ring 101 and the insulating window 12 from tilting, and improves the assembly safety of the insulating window 12.

[0036] In yet another embodiment, Figure 4As shown, the shape of the main body ring 201 is an open ring, and the opening can be set at any position in the circumferential direction of the main body ring 201. Compared with a closed ring, the inner diameter of the open ring can be finely adjusted by adjusting the tension at the opening, which enables the fixed plug 103 and the adjusting plug 104 provided on the open ring to fit more closely to the circumferential side wall of the insulating window 12, increasing the extrusion force of the fixed plug 103 and the adjusting plug 104 on the open ring, and thus improving the fixing effect between the main body ring 201 and the insulating window 12. At the same time, when the open ring lifts the insulating window 12, the stress is mainly concentrated at the opening, while the stress in other parts of the open ring is relatively small, which can avoid generating uniform high stress on the entire open ring, thereby prolonging the service life of the main body ring 201 and reducing the risk of fracture.

[0037] In yet another embodiment, as Figure 5 shown, the main body ring 301 is composed of a plurality of arc segments 311. The plurality of arc segments 311 are evenly distributed along the circumferential direction of the insulating window 12 to form a ring shape, and at least one fixed plug 103 and / or adjusting plug 104 is provided on each arc segment 311. Specifically, in this embodiment, the main body ring 301 is composed of two arc segments 311. The inner diameter of the main body ring 301 formed by the two arc segments 311 surrounding the insulating window 12 is greater than or equal to the outer diameter of the insulating window 12. One fixed plug 103 and one adjusting plug 104 are provided on each arc segment 311, and the two arc segments 311 are connected by a suspension rod 151. During use, the two arc segments 311 are respectively sleeved on the circumference of the insulating window 12, the position of the adjusting plug 104 in the radial direction of the arc segment 311 is adjusted, the insulating window 12 is clamped inside the main body ring 301 to make the insulating window 12 concentric with the main body ring 301, and then the positioning member 102 on the lower surface of the main body ring 301 is inserted into the corresponding positioning hole 14 to complete the concentric installation of the main body ring 301 and the inner liner 11, thereby realizing the concentric installation of the insulating window 12 and the inner liner 11 at one time. By splitting the main body ring 301 into multiple arc segments 311, each split arc segment 311 can independently bear the force, thereby improving the structural stability and service life of the main body ring 301; at the same time, if a certain part of the main body ring 301 is damaged, only the corresponding arc segment 311 needs to be replaced instead of the entire main body ring 301, reducing the maintenance cost.

[0038] After the inductively coupled plasma (ICP) reaction device operates at high temperature for a long time, the sealing ring 13 between the inner liner 11 and the insulating window 12 tightly adheres the inner liner 11 and the insulating window, resulting in time-consuming and laborious disassembly of the insulating window 12. Based on this, as Figures 1 to 5The jig of any of the embodiments shown further includes a jacking member 106. A plurality of through holes 161 are provided in the circumferential direction of the main body ring members 101, 201, and 301. The jacking member 106 can pass through the through holes 161 and contact the top of the inner liner 11. For Figure 1 and Figure 2 taking the jig 100 shown as an example, when the insulating window 12 is disassembled from the inner liner 11 by using the jig 100, first, the main body ring member 101 is sleeved on the circumference of the insulating window 12, and the radial position of the adjusting plug 104 is adjusted to fix the adjusting plug 104 and the fixed plug 103 to the insulating window 12. In this embodiment, the shape of the jacking member 106 is a cylindrical pin with equal diameter. By applying an impact force to the cylindrical pin, the cylindrical pin can move downward along the axial direction of the main body ring member 101 until the bottom of the cylindrical pin abuts against the top of the inner liner 11. Furthermore, the cylindrical pin provides an upward acting force to separate the insulating window 12 from the inner liner 11. By providing the jacking member 106, the insulating window 12 and the inner liner 11 can be pre-separated, which is convenient for later removing the insulating window 12 from the inner liner 11 through the lifting member 105.

[0039] Optionally, the jacking member 106 is a first screw, and the through hole 161 provided on the main body ring member is a threaded hole matching the first screw. The first screw makes a screwing-in movement in the threaded hole, so that the first screw moves downward along the axial direction of the main body ring member until the first screw abuts against the top of the inner liner 11. The first screw provides an upward acting force to separate the insulating window 12 from the inner liner 11. This screw structure has the advantages of labor saving and strong controllability, and avoids damage to the top of the inner liner 11 caused by excessive impact force applied.

[0040] In summary, the jig for disassembling and assembling the insulating window provided by the present utility model can realize the concentric setting of the insulating window 12 and the main body ring member 101 by adjusting the radial positions of the fixed plug 103 and the adjusting plug 104 provided on the main body ring member 101; at the same time, by inserting the positioning member 102 on the lower surface of the main body ring member 101 into the positioning hole 14 on the top of the inner liner 11, the concentric installation of the main body ring member 101 and the inner liner 11 is completed. Furthermore, the concentric installation of the insulating window 12 and the inner liner 11 is realized at one time, reducing the wear of the sealing ring 13 below the insulating window 12. Secondly, by providing the jacking member 106, the insulating window 12 and the inner liner 11 can be separated, which is convenient for removing the insulating window 12 from the inner liner 11 through the lifting member 105, improving the convenience of disassembling and assembling the insulating window 12, and also avoiding damage to the insulating window 12 and the inner liner 11 caused by violent disassembly.
