[Technical field]
[0001] The present invention relates to the technical field of semiconductor processing, and more particularly to a wafer processing apparatus, a wafer processing system and a control method. [Background technology]
[0002] Wafer processing is used to process semiconductors by techniques including physical vapor deposition (PVD), chemical vapor deposition (CVD), plasma enhanced chemical vapor deposition (PECVD), atomic layer deposition (ALD), plasma enhanced atomic layer deposition (PEALD), pulse deposition layer (PDL), molecular layer deposition (MLD), plasma enhanced pulsed deposition layer (PEPDL) processing, etching and etch inhibitor removal, etc.
[0003] When processing a wafer, it is necessary to first preheat the wafer. Conventional wafer processing apparatuses generally have a heating plate installed in the processing apparatus when preheating the wafer, and the wafer is preheated by the heating plate before the processing process, and the wafer is processed only after it reaches a predetermined processing condition.
[0004] This processing method causes problems in that the wafer processing time is long and the efficiency is low. Summary of the Invention [Problem to be solved by the invention]
[0005] The objective of the present invention is to provide a wafer processing apparatus, a wafer processing system and a control method, in which wafers that need to be processed can be directly transported to the processing chamber by the driving device for processing, and wafers that need to be adjusted or do not need to be directly processed can be adjusted or stored in the transfer chamber, thereby reducing the time that wafers between different batches occupy the operating mechanism and waiting time, and improving the wafer processing efficiency; and the transfer chamber and the mounting assembly provide the basic conditions for synchronous processing of multiple wafers or multiple batches of wafers, thereby solving the problems of long occupancy time and low efficiency when processing wafers in the prior art. [Means for solving the problem]
[0006] In order to achieve the above object, the present invention provides a wafer processing apparatus, the wafer processing apparatus including a drive unit, a transfer chamber, a processing chamber, a first bleed unit, a second bleed unit, and a mounting assembly, the processing chamber communicates with the transfer chamber, the transfer chamber is used to provide a sealed space, the first bleed unit communicates with the transfer chamber, the first bleed unit is used to extract gas in the transfer chamber and perform a first vacuum process on the transfer chamber, the processing chamber is used to process a wafer. a second bleed device communicating with the processing chamber, the second bleed device being used to extract gas within the processing chamber and perform a second vacuum process on the processing chamber; the mounting assembly being installed in the transfer chamber, the mounting assembly being used to place a wafer thereon; the drive device being used to adjust a position of the mounting assembly in the transfer chamber, and the drive device being further used to drive the mounting assembly to move between the transfer chamber and the processing chamber.
[0007] The beneficial effects of the wafer processing apparatus of the present invention are as follows: by setting the processing chamber, the wafer placed in the processing chamber is processed, where the processing includes heating, deposition, coating, etching or other processing methods; by setting the mounting assembly, the wafer is supported; by setting the transfer chamber and performing a first vacuum process on the transfer chamber to provide a sealed space, the wafer can be adjusted or stored in the transfer chamber, and a second vacuum process on the processing chamber to provide a sealed space, thus the driving device, the transfer chamber and the processing chamber can flexibly control multiple batches of wafers to be adjusted or stored in the transfer chamber under the first vacuum condition, which avoids the prior art transferring the wafers in a non-vacuum environment before entering the processing chamber, which damages the quality of the wafers. In the present invention, a transfer chamber under a first vacuum condition is set up to store wafers, so that different batches of wafers can be flexibly controlled to be transported to the processing chamber for processing, and the wafers can be freely moved between the transfer chamber under a first vacuum condition and the processing chamber under a second vacuum condition while ensuring that the wafers are not damaged, providing a basic condition for simultaneously processing multiple or multiple batches of wafers. The driving device is set up to move the loading assembly between the transfer chamber and the processing chamber, or adjust the position of the loading assembly in the transfer chamber.As can be seen from this, in the wafer processing apparatus of the present application, the driving device, the transfer chamber and the processing chamber can flexibly control the wafers to be adjusted or stored in the transfer chamber, or the wafers to be transported to the processing chamber for processing, and multiple wafers can be placed on one mounting assembly for processing or transport according to demand, thereby reducing the time that one or a set of wafers occupies the processing chamber, and improving the processing efficiency of the processing apparatus; further, according to the flexible use of the driving device, the transport time between wafers of different batches or the interval time between processing wafers of different batches can be reduced, thereby further improving the processing efficiency of the processing apparatus.

In the present invention, by providing a transfer chamber under the first vacuum condition for wafer storage, wafers of different batches can be flexibly controlled to be transported to the heating chamber or the process chamber for processing, thereby reducing the waiting time for wafer pre-heating processing of different batches and improving the processing efficiency of wafers of different batches.

[0067] Specifically, when the processing chamber 100 is the process chamber 101 and / or the heating chamber 102, the second driving mechanism 402 is used to move the mounting assembly 2 between the process chamber 101 and the transfer chamber 103, and / or the second driving mechanism 402 is used to move the mounting assembly 2 between the heating chamber 102 and the transfer chamber 103.
[0068] In some specific embodiments of the present invention, the transfer device 403 is set as a support plate, the transfer device 403 is provided with a hollow space, and the placement assembly 2 is placed in the hollow space. The first driving device 4 is a rotary motor, and the rotary shaft of the rotary motor is connected to the transfer device 403, so that the transfer device 403 can rotate with the rotation of the rotary motor, and further rotate the placement assembly 2 horizontally, that is, adjust the position of the placement assembly 2 in a horizontal plane.
[0069] By adjusting, the mounting assembly 2 can be moved from a position located below the process chamber 101 to a position located below the heating chamber 102. By adjusting, the mounting assembly 2 can also be moved from a position located below the heating chamber 102 to a position located below the process chamber 101.
[0070] The second driving device 4 is an electric cylinder, an air cylinder, a worm gear or other structure. The second driving mechanism 402 is installed vertically, and in use, the second driving device 4 can move the first mounting assembly 202 and / or the second mounting assembly 3 up and down, i.e., adjust the height position of the mounting assembly 2, and further realize the movement of the first mounting assembly 202 and the second mounting assembly 3 between the process chamber 101, the heating chamber 102 and the transfer chamber 103.
[0071] In some embodiments, a fixed part of the second driving mechanism 402 is installed under the transfer chamber 103, and a movable part of the second driving mechanism 402 is installed inside the transfer chamber 103. By installing in this way, the size of the space of the transfer chamber 103 can be reduced, and it is possible to avoid the transfer chamber 103 being installed with too large a space, which increases the manufacturing difficulty, or increases the manufacturing difficulty of the environment required for the transfer chamber 103.
[0072] Also, in some embodiments, the first drive mechanism 401 and / or the second drive mechanism 402 may be located at the front, back, left, right, or other orientation of the transfer chamber 103.
[0073] In some specific embodiments, the inner diameter of the hollow portion is smaller than the outer diameter of the mounting assembly 2, and thus the mounting assembly 2 can be lowered into the transfer device 403 as the movable part of the second driving mechanism 402 descends, and is restricted by the transfer device 403 so that the movable part of the second driving mechanism 402 can be detached from the mounting assembly 2, and vice versa.
[0074] FIG. 6 is a structural schematic diagram of a third driving mechanism in the second embodiment of the present invention.
[0075] In some embodiments of the present invention, the transfer device 403 is detachably connected to the first driving mechanism 401. The driving mechanism 401 further includes a third driving mechanism 404, which is installed on one side of the transfer device 403, and which is used to move the transfer device 403 and the placement assembly 2.
[0076] In some specific embodiments of the present invention, an irregular protrusion is provided on the underside of the transfer device 403, a groove that fits the irregular protrusion is provided on the movable end of the first driving mechanism 401, the transfer tool and the first driving mechanism 401 are connected via the protrusion and the groove, and the third driving mechanism 404 is installed on the underside of the transfer device 403.

[0077] In some embodiments, the driving device 4 further includes a connection mechanism (not shown), which is installed on the placement assembly 2 or the transfer device 403, a first fastening part is installed on the connection mechanism (not shown), the placement assembly 2 or the transfer device 403 is provided with a second fastening part that matches the first fastening part, and the connection mechanism is used to connect the transfer device 403 and the connection member. In use, the placement assembly 2 and the transfer device 403 are integrally formed by engaging the first fastening part with the second fastening part through the connection mechanism, and when the second driving mechanism 402 drives the placement assembly 2 to move, the transfer device 403 can achieve the effect of interlocking, and further move all the placement assemblies 2 in the transfer device 403 up and down synchronously.
[0078] In some embodiments of the present invention, the sealing method between the driving device 4 and the base 1 is a dynamic seal. In some specific embodiments of the present invention, the type of the dynamic seal may be a magnetic fluid seal. In this way, the entire non-moving part of the second driving mechanism 402 is located outside the transfer chamber 103, and impurities between the fixed part and the moving part of the second driving mechanism 402 can be reduced from entering the transfer chamber 103.

[0080] In some embodiments of the present invention, there are at least two process chambers 101, and there are at least two mounting assemblies 2. In some embodiments, there are at least two first mounting assemblies 202 and / or at least two second mounting assemblies 3. There are at least two second driving mechanisms 402, and each of the second driving mechanisms 402 operates independently.
[0081] In some specific embodiments of the present invention, two process chambers 101 are provided, one heating chamber 102 is provided, two first mounting assemblies 202 and two second mounting assemblies 3 are provided, four second driving mechanisms 402 are provided, and the four second driving mechanisms 402 operate independently.
[0082] It should be noted that when the heating conditions are the same, multiple mounting assemblies 2 may be heated in the same heating chamber 102, so the number of heating chambers 102 may still be one when multiple mounting assemblies 2 are installed.
[0083] When one mounting assembly 2 and two second driving mechanisms 402 are installed, both of the two second driving mechanisms 402 are used to drive the mounting assembly 2 to move. For example, the first second driving mechanism 402 drives the mounting assembly 2 to move to the heating chamber 102, and the second second driving mechanism 402 drives the mounting assembly 2 to move to the process chamber 101.
[0084] In alternative embodiments, the process chambers 101 may be configured in one, three, four or other numbers.
[0085] In alternative embodiments, two, three or other numbers of heating chambers 102 may be provided.
[0086] In another embodiment, the first mounting assembly 202 and the second mounting assembly 3 may be provided in one, three, four or other numbers.
[0087] In another embodiment, the second driving mechanism 402 may be installed in one, two, three, four or other numbers. It should be noted that, when actually installed, the same second driving mechanism 402 may be installed to simultaneously control the lifting and lowering of two, three or more mounting assemblies 2. For example, five mounting assemblies 2 are installed, two second driving mechanisms 402 are installed, one second driving mechanism 402 controls the lifting and lowering of two mounting assemblies 2, and the other second driving mechanism 402 controls the lifting and lowering of three mounting assemblies 2.
[0088] In some other embodiments, two of the second drive mechanisms 402 may control the elevation and lowering of the same mounting assembly.
[0089] In some embodiments of the present invention, each of the mounting assemblies 2 is provided with N supports 201, each of which is used to support the wafer, where N is an integer greater than 1.
[0090] In some specific embodiments of the present invention, the mounting assembly 2 is provided with 25 supports 201, so that 25 wafers can be mounted on one mounting assembly 2 at the same time.
[0091] In alternative embodiments, any other number of supports 201 may be provided.
[0092] In some embodiments of the present invention, the apparatus further includes a seal member (not shown) disposed on the mounting assembly 2 for isolating the transfer chamber 103 from the process chamber 101 and / or the heating chamber 102.
[0093] In some specific embodiments of the present invention, the seal member (not shown) is installed on the first mounting assembly 202 and the second mounting assembly 3, and when the first support member or the second support member moves into the process chamber 101 or the heating chamber 102, the side of the seal member abuts against the side wall of the process chamber 101 or the heating chamber 102. At this time, the seal member and the first mounting assembly 202 or the second mounting assembly 3 isolate the process chamber 101 and / or the heating chamber 102 from the transfer chamber 103. As a result, only the heating chamber 102 is heated during heating, and only the wafer in the process chamber 101 is processed during processing.
[0094] In another embodiment, a movable plate, a gate valve, or other structural member may be installed at a connection point between the process chamber 101 and / or the heating chamber 102 and the transfer chamber 103, and a moving mechanism can be installed to move the movable plate, the gate valve, or the other structural member. Thus, when the first mounting assembly 202 and / or the second mounting assembly 3 are positioned in the transfer chamber 103, the communication between the process chamber 101 and / or the heating chamber 102 and the transfer chamber 103 can still be blocked by the movable plate, the gate valve, or the other structural member.

[0098] In some embodiments, one or more fourth driving mechanisms 6 may be provided, and when one fourth driving mechanism 6 is provided, the wafer processing position corresponding to the fourth driving mechanism 6 has a rotation function or an angle adjustment function. In some embodiments, a plurality of fourth driving mechanisms 6 may be provided, and each of the fourth driving mechanisms 6 is provided in one-to-one correspondence with each of the mounting assemblies 2.
[0099] It should be noted that, in order to avoid mutual interference between the third driving mechanism 404 and the second driving mechanism 402, the height of the third driving mechanism 404 and the height of the transfer device 403 may be different. Also, in some embodiments, the third driving mechanism 404 may be installed in the transfer device 403.
[0100] In another embodiment, the third drive mechanism 404 may be arranged in the form of a double pinion.
[0101] Furthermore, in some embodiments, the third drive mechanism 404 may be mounted within the movable end of the second drive mechanism 402, by mounting the third drive mechanism 404 to a rotary air cylinder, rotary motor, or other drive. It should be noted that when the third drive mechanism 404 is mounted to the second drive mechanism 402, the third drive mechanism 404 moves with the movement of the movable end of the second drive mechanism 402.

When in use, the fifth driving mechanism 7 is turned on to move the movable end of the fifth driving mechanism 7 to be in close contact with the first fixed part 104, and as the fifth driving mechanism 7 continues to be turned on, the fifth driving mechanism 7 pushes up the first fixed part 104 and further opens the transfer chamber 103. At this time, the structure inside the transfer chamber 103 can be cleaned, repaired or replaced. When it is necessary to control the transfer chamber 103 to close, the fifth drive mechanism 7 is controlled to move in the reverse direction, and the first fixing part 104 automatically descends under the action of gravity until it comes into close contact with the second fixing part 105.
