[0049] In the prior art, the design of the heating plate is mainly divided into fixed type and rotating type.

[0052] Please refer to Figure 1 , Figure 1 Semiconductor processing equipment provided according to some embodiments of the present invention is shown.

[0054] Please refer to Figure 2 , Figure 2 A schematic structural diagram of a heating plate angle adjustment device provided according to some embodiments of the present invention is shown.

[0055] like Figure 2 As shown, the heating plate angle adjustment device includes a support seat 70, a ball seat 60, a water-cooling block 40 and a plurality of top screw assemblies 50. Here, the support seat 70 is fixedly connected to the slider of the machine table of the semiconductor device processing equipment, and rises and falls with the slider. The upper end of the ball seat 60 can be connected to the heating plate body 30 via the water-cooling block 40. The lower surface of the water-cooling block 40 is a raised spherical surface, and the spherical surface is movably connected to the upper end of the ball seat 60 to adjust the axial tilt angle of the heating plate body 30. The plurality of top screw assemblies 50 adjust the axial tilt angle of the heating plate body 30 by pushing the water-cooling block 40 laterally.

[0056] Please refer to Figure 3 to Figure 6 , Figure 3 A schematic structural diagram of a support base provided according to some embodiments of the present invention is shown. Figure 4 A schematic structural diagram of a ball seat provided according to some embodiments of the present invention is shown. Figure 5 A schematic structural diagram of a water cooling block provided according to some embodiments of the present invention is shown. Figure 6 A schematic structural diagram of a jackscrew device provided according to some embodiments of the present invention is shown.

[0057] like Figure 3 As shown, the support base 70 is fixedly connected to a machine table of a semiconductor device processing equipment, and a plurality of first limiting structures 701 distributed along the circumferential direction are provided on the upper surface of the support base 70.

[0058] Further, the first limiting structure 701 is configured as a radially extending concave structure or convex structure, and the second limiting structure 601 is correspondingly configured as a radially extending convex structure or concave structure. Here, the ball seat 60 is lifted to adjust the circumferential deflection angle of the heating plate body 30, and dropped to lock the circumferential deflection angle of the heating plate body 30.

[0059] Further, the plurality of first limiting structures 701 may include a plurality of grooves distributed along the circumference of the support seat 70 , and the plurality of second limiting structures 601 may include a plurality of tooth-shaped protrusions distributed along the circumference of the ball seat 60 .

[0060] In some embodiments, the number of grooves may be 360 ​​and surround the support seat 70, and each adjacent two grooves form a central angle of 1° on the circumference thereof. The plurality of tooth-like protrusions may be divided into three sections, each section including 30 tooth-like protrusions, and each adjacent two tooth-like protrusions form a central angle of 1° on the circumference thereof.

[0061] like Figure 4 As shown, in some embodiments, the upper end of the ball seat 60 can be directly connected to the heating plate body 30, and its lower surface is provided with a plurality of second limiting structures 601 distributed along the circumference, which are used to cooperate with the plurality of first limiting structures 701 to adjust and lock the circumferential deflection angle of the heating plate body 30.

[0062] like Figure 5-6 As shown, in some embodiments, the upper end of the water cooling block 40 is connected to the heating plate body 30, and its lower surface is a convex spherical surface. The spherical surface is movably connected to the upper end of the ball seat 60, and the water cooling block 40 can rotate at various angles on the ball seat 60 to adjust the axial tilt angle of the heating plate body 30.

[0063] The multiple top screw assemblies 50 respectively include a connecting seat 501, a nut 502 and a first top screw 503, wherein the connecting seat 501 of the multiple top screw assemblies 50 is circumferentially installed at multiple positions of the ball seat 60, and a corresponding nut 502 is provided thereon, and the first top screw 503 of each top screw assembly 50 respectively abuts against the side of the water cooling block 40 via the corresponding nut 502, so as to adjust the axial inclination angle of the heating plate body 30 by laterally pushing the water cooling block 40.

[0064] Furthermore, the side of the water-cooling block 40 is provided with a first threaded hole 401 (for example, three evenly distributed) at a position where the first top screw 503 contacts the side of the water-cooling block 40. The first top screw 503 is screwed into the first threaded hole 401 to pull the corresponding position of the water-cooling block 40 closer and raise it, or is screwed out of the first threaded hole 401 to push the corresponding position of the water-cooling block 40 farther and lower it.

[0065] Please refer to Figure 7A to Figure 7B , Figure 7A to Figure 7B A schematic diagram of a locking structure provided according to some embodiments of the present invention is shown.

[0066] like Figure 7A to Figure 7B As shown, the support seat 70 and the ball seat 60 are also provided with a first locking structure 801 corresponding to multiple positions (for example: threaded holes with bolts, and / or through holes with bolts and nuts 502, etc.), which are used to lock the support seat 70 and the ball seat 60 after the circumferential deflection angle of the heating plate body 30 is adjusted.

[0067] In some embodiments, the ball seat 60 and the water cooling block are further provided with a plurality of corresponding second locking structures 802 for locking the ball seat 60 and the water cooling block 40 after the axial tilt angle of the heating plate body 30 is adjusted.

[0068] In some embodiments, the heating plate angle adjustment device further includes a plurality of second top screws 702 distributed in multiple directions on the side of the support seat 70, and used to drive the heating plate body 30 to perform radial centering adjustment via the support seat 70, thereby driving the heating plate thereon to be centered.

[0069] Here, in the absence of a locking structure, multiple bolts directly bear the gravity of the heating plate. After the equipment has been running for a long time, a slight looseness between the threads will directly affect the gap of the heating plate. Therefore, the locking structure can prevent the heating plate gap problem caused by loose threads, thereby effectively improving the process quality of the film.

[0070] The following will describe the working principles of the heating disk angle adjustment device and the semiconductor device processing equipment in combination with some embodiments of the heating disk angle adjustment method. Those skilled in the art will understand that these embodiments of the heating disk angle adjustment method are only some non-restrictive implementation methods provided by the present invention, which are intended to clearly demonstrate the main concept of the present invention and provide some specific solutions that are convenient for the public to implement, rather than to limit all functions or all working modes of the heating disk angle adjustment device. Similarly, the heating disk angle adjustment device is also only some non-restrictive implementation methods provided by the present invention, and does not constitute a limitation on the execution subject or execution order of each step in these heating disk angle adjustment methods.

[0071] Please refer to Figure 8 , Figure 8 A schematic flow chart of a method for adjusting the angle of a heating plate provided according to some embodiments of the present invention is shown.

[0072] like Figure 8 As shown, the heating plate angle adjustment device can first adjust the axial tilt angle of the heating plate via the convex spherical surface on the lower surface of the water cooling block 40 of the heating plate angle adjustment device. Here, the upper end of the water cooling block 40 is fixedly connected to the heating plate, and the spherical surface at the lower end thereof is movably connected to the upper end of the ball seat 60 of the heating plate angle adjustment device.

[0073] Afterwards, the circumferential deflection angle of the heating plate is adjusted and locked by using a plurality of second limiting structures 601 distributed circumferentially arranged on the lower surface of the ball seat 60 in cooperation with a plurality of first limiting structures 701 distributed circumferentially arranged on the upper surface of the support seat 70 therebelow, wherein the support seat 70 is fixedly connected to the machine table of the semiconductor device processing equipment.

[0074] Finally, the heating plate is driven to be radially centered via a plurality of second top screws 702 distributed in multiple directions on the side surface of the support base 70 .

[0075] Furthermore, after the heating disk is radially centered, the heating disk angle adjustment device also needs to calibrate the spacing of the heating disk.

[0076] Specifically, the heating plate angle adjustment device cooperates with the automatic gapping system (AGS) to calibrate the spacing of the heating plate. Specifically, the AGS is placed on the support ring, the device is evacuated to a vacuum state, and the heating plate is moved upward until the computer displays the spacing distances of three places, and the first top screws 503 evenly distributed at the three places are adjusted to make the displayed spacing distances of the three places consistent, thereby completing the spacing calibration of the heating plate.

[0077] In addition, please continue to refer to Figure 1 and Fig. 9 , Fig. 9 A schematic diagram of installing a support ring and a wafer according to some embodiments of the present invention is shown.

[0078] like Figure 1 and Fig. 9 As shown, the adjustment device for the angle of the heating plate can also be provided with a support ring 20. The support ring 20 is fixed on the heating plate. In the process of depositing a thin film on the back of the wafer 10, a positioning groove 101 (usually V-shaped) is provided directly below the wafer 10 for positioning or marking. In order to prevent the deposition gas from entering the front area of ​​the wafer 10 through the small groove, resulting in the growth of a film on the front of the wafer 10, a convex surface is usually designed to block the position of the corresponding groove of the support ring 20 of the wafer 10. However, due to the complex installation structure of the support ring 20 of the wafer 10, the heating plate and the water-cooling block 40, in order to ensure that the groove of the wafer 10 coincides with the convex surface of the support ring 20, the processing accuracy of the device is extremely high, the installation difficulty is extremely great, and it is easy to cause the unqualified rate of the heating plate to increase.

[0079] Therefore, the device can also adjust the angle of the heating plate by meshing the small teeth, thereby adjusting the angle of the support ring through the heating plate, so as to achieve the purpose of shielding and adjusting the V-shaped groove of the wafer after the device is installed.

[0080] In summary, the heating plate angle adjustment device, method, and semiconductor device processing equipment provided by the present invention can be used to avoid the installation of a heating plate rotating mechanism, and can achieve circumferential angle adjustment, thereby reducing limitations in sealing, transmission and maintenance, and effectively reducing costs.

[0081] Although the above methods are illustrated and described as a series of actions for simplicity of explanation, it should be understood and appreciated that these methods are not limited by the order of the actions, because according to one or more embodiments, some actions may occur in a different order and / or concurrently with other actions from those illustrated and described herein or not illustrated and described herein but understandable to those skilled in the art.

[0082] The previous description of the disclosure is provided to enable any person skilled in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the spirit or scope of the disclosure.
