Description

Technical Field

[0001] This utility model relates to the field of semiconductor cleaning technology, and in particular to a semiconductor cleaning fluid dispensing system. Background Technology

[0002] In semiconductor manufacturing, the cleaning step is a crucial step in ensuring product quality. This process typically requires a large amount of cleaning fluid to effectively remove surface contaminants and residues. When semiconductor materials are separated from the cleaning fluid, some of the cleaning fluid is often carried away with them. This phenomenon not only reduces the concentration of the cleaning fluid but may also affect the effectiveness and efficiency of subsequent cleaning processes. Therefore, in order to maintain the optimal performance of the cleaning fluid and ensure the effectiveness of the cleaning process, the cleaning fluid must be replenished regularly.

[0003] Current cleaning fluid filling systems require operators to check the remaining amount of cleaning fluid before determining whether to add more. They cannot automatically complete the filling process. To address this issue, we propose a semiconductor cleaning fluid filling system. Utility Model Content

[0004] The purpose of this invention is to provide a semiconductor cleaning fluid dispensing system to solve the problems mentioned in the background art.

A pump body is mounted on the upper surface of the storage tank. A suction pipe is fixedly connected to the input end of the pump body. The bottom end of the suction pipe penetrates the storage tank and extends to the bottom of the storage tank. A drain pipe is fixedly connected to the output end of the pump body. A set of distribution pipes is fixedly connected to the outer surface of the drain pipe. A ring-shaped connecting rod is fixedly connected to the outer surface of each distribution pipe. A shield is fixedly connected to the bottom end of each set of connecting rods. A level gauge is mounted on the bottom surface of the shield.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 In this utility model, a semiconductor cleaning fluid addition system includes a storage tank 1, which can be used to store the cleaning agent.

[0020] A liquid level window 11 is fixedly embedded on the front of the liquid storage tank 1. The liquid level window 11 allows staff to easily observe the remaining cleaning agent inside the liquid storage tank 1 and add cleaning agent in a timely manner.

[0021] The bottom surface of the liquid storage tank 1 is fixedly connected with a ring of supporting legs 10. Each supporting leg 10 is located on the edge side of the bottom of the liquid storage tank 1, and the supporting legs 10 can provide stable support for the liquid storage tank 1.

[0022] A set of cleaning tanks 9 arranged at equal intervals is provided on the right side of the storage tank 1. A pump body 3 is installed on the upper surface of the storage tank 1. The input end of the pump body 3 is fixedly connected to the suction pipe 2. The bottom end of the suction pipe 2 passes through the storage tank 1 and extends to the bottom of the storage tank 1. The output end of the pump body 3 is fixedly connected to the drain pipe 5. A distribution pipe 4 is fixedly connected to the outer surface of the drain pipe 5. The pump body 3 can draw the cleaning agent, and the drain pipe 5 will divert the cleaning agent to the inner wall of the distribution pipe 4, thereby completing the addition of cleaning agent inside the cleaning tank 9.

[0023] A support plate 7 is fixedly connected to the outer surface of the liquid storage tank 1. A set of equally spaced support columns 6 are fixedly connected to the upper surface of the support plate 7. The top of each support column 6 is connected to the outer surface of the drain pipe 5. The drain pipe 5 can be supported and fixed by the cooperation of the support plate 7 and the support column 6.

[0024] Each dispensing tube 4 has a ring of connecting rods 14 fixedly connected to its outer surface. The bottom of each set of connecting rods 14 is fixedly connected to a shield 15. A level gauge 16 is installed on the bottom surface of the shield 15. The connection of the connecting rods 14 and the shield 15 can fix the level gauge 16. At the same time, the shield 15 can shield the top of the level gauge 16, which can prevent the level gauge 16 from being damaged by the cleaning agent.

[0025] Each dispensing tube 4 is equipped with a solenoid valve 13 on its outer surface. A controller 12 is installed on the front of the storage tank 1. The controller 12 can be used to set the liquid level value of the level gauge 16. When the level gauge 16 detects a low liquid level value, the controller 12 will start the pump body 3 and open the solenoid valve 13 to complete the filling of the cleaning agent. At the same time, when the level gauge 16 detects the highest value of the cleaning agent, the controller 12 will stop the pump body 3 and close the solenoid valve 13, thereby automatically completing the filling of the cleaning agent.

[0026] Each cleaning tank 9 has a partition 8 fixedly connected to its inner wall. The partition 8 can be used to divide the inside of the cleaning tank 9 into a cleaning area and a cleaning fluid filling area to prevent collisions between the semiconductor and the liquid distribution pipe 4 and the liquid level gauge 16 during the cleaning process.

[0027] The working principle of this utility model is as follows: When cleaning agent needs to be added, the level gauge 16 is inserted into the corresponding cleaning tank 9, and the level value is set by the controller 12. When the level gauge 16 detects that the liquid level value inside the cleaning tank 9 is low, the controller 12 will start the pump body 3 and open the corresponding solenoid valve 13. The pump body 3 will draw the cleaning agent inside the storage tank 1 into the drain pipe 5 and then enter the corresponding cleaning tank 9 through the distribution pipe 4 until the liquid level inside the cleaning tank 9 reaches the highest value set by the level gauge 16. At this point, the controller 12 will stop the pump body 3 and close the corresponding solenoid valve 13, thus achieving the effect of automatic cleaning agent addition.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
