Description

Technical Field

[0001] The utility model relates to the technical field of photoresist, and particularly relates to a photoresist sealing and liquid absorbing combination. Background Technique

[0002] In the liquid crystal panel, chip, and semiconductor industries, photoresist is a key material used in the manufacturing process of chips and devices. Generally, photoresist products require indicators such as particle size, moisture, and metal impurities to be in a relatively low range. Therefore, it is necessary to avoid contamination of the photoresist during the manufacturing process to ensure the performance of the liquid crystal panel and circuit. With the continuous increase in the size of liquid crystal panels and the continuous reduction in the size of integrated circuits, the requirements for the content of metal impurities and particle size in the production manufacturing process in factories are also continuously increasing. The highest-end semiconductor chips require the content of single metal impurities in raw materials such as photoresist to be controlled within 1 ppb, and the particle size above 0.15 microns to be controlled within 10 / mL. The packaging containers of photoresist must also be controlled to the highest standards. Otherwise, the particulate matter and metal impurities in the container will adhere to the wafer during the photolithography process, causing the microcircuit to be open-circuited or short-circuited by the particulate matter, resulting in defects; furthermore, it will affect the yield of the entire batch of semiconductor products.

[0003] Currently, in order to obtain the photoresist in the packaging container, the common practice is to insert a straw into the opened packaging container for suction. Although this method meets the basic requirements for taking out the photoresist from the container to a certain extent, when deeply analyzing its operation process and effect, it can be clearly seen that it has the following defects:

[0004] 1) Direct exposure to air: When the opening of the packaging container is opened, in order to insert the straw for liquid absorption, the photoresist is directly exposed to the air. This means that dust, particles, moisture, and possibly existing metal impurities in the air all have the opportunity to enter the photoresist, thereby contaminating its purity.

[0005] 2) Lack of effective isolation measures:

[0006] The method of inserting the straw does not provide an effective mechanism to isolate the direct contact between air and the photoresist, nor can it prevent pollutants in the air from entering the photoresist. Content of the Utility Model

[0040] Please refer to Figures 1 to 11, this embodiment provides a photoresist sealing and liquid suction combination, including a packaging container 1, a straw 2 and a connector 3. The packaging container 1 is used to store liquids such as photoresist. The top of the packaging container 1 has an opening 11; the straw 2 is arranged inside the packaging container 1, the upper end of the straw 2 extends to the opening 11 of the packaging container 1, and the lower end of the straw 2 extends to the inner bottom end of the packaging container 1; the lower end of the connector 3 is threadedly sleeved outside the opening 11 of the packaging container 1 to seal the opened packaging container 1, avoiding direct exposure of liquids such as photoresist to air during the liquid suction process, reducing the risk of photoresist being contaminated and oxidized, and ensuring the purity of the photoresist; the connector 3 is provided with a pressure channel 311 and a liquid suction channel 312 that penetrate up and down. The pressure channel 311 is used to connect an external pressure pipe. External equipment can introduce nitrogen or other gases into the packaging container 1 along the pressure channel 311 and the straw 2 through the external pressure pipe. A one-way valve 3111 is arranged in the pressure channel 311 so that gas can enter the packaging container 1 from the external pressure pipe, while the gas or liquid in the packaging container 1 cannot go out in the reverse direction along the pressure channel 311; the liquid suction channel 312 is used to connect an external liquid suction pipe so that external equipment can suck the liquid in the packaging container 1 through the external liquid suction pipe.

[0041] In the photoresist sealing and liquid suction combination of this embodiment, the straw 2 in the packaging container 1, the external pressure pipe and the external liquid suction pipe of external equipment are connected through the connector 3. The external pressure pipe of external equipment injects nitrogen or other gases into the packaging container 1 through the pressure channel 311 to form a pressure difference, thereby driving liquids such as photoresist to be sucked out to external equipment through the liquid suction channel 312 by the external liquid suction pipe; the entire liquid suction process is carried out in a sealed environment, and it is difficult for external impurities and pollutants to enter the interior of the packaging container 1, thus effectively isolating the photoresist from the external environment, improving the purity of the photoresist, and at the same time improving the efficiency and accuracy of liquid suction; this photoresist sealing and liquid suction combination is not only applicable to the photoresist liquid suction process of G11 and G8.5 liquid crystal panel production lines, but can also be appropriately adjusted and improved according to needs to be applicable to the liquid suction requirements of other similar liquids, with high versatility and flexibility.

[0042] Please refer to Figure 2 , Figures 6 to 8 , in one embodiment, the outer wall of the opening 11 of the packaging container 1 is provided with a first external thread 111, and the inner wall of the lower end of the connector 3 is provided with a first internal thread 321 adapted to the first external thread 111. Through the threaded connection of the first external thread 111 and the first internal thread 321, the connector 3 can be firmly fixed on the opening 11 of the packaging container 1, thus forming a tight sealing environment. At the same time, the threaded connection has high durability and can withstand multiple installations and removals without being easily damaged, enabling the photoresist sealing and liquid suction combination to be reused, reducing the use cost and improving the resource utilization efficiency.

[0043] Please refer to Figure 7 and Figure 8 In one embodiment, the inner wall of the upper end of the pressurizing channel 311 is provided with a second internal thread 3112 adapted to the second external thread at the end of the external pressurizing tube, and the inner wall of the upper end of the liquid suction channel 312 is provided with a third internal thread 3121 adapted to the third external thread at the end of the external liquid suction tube. By providing the second internal thread 3112 on the inner wall of the upper end of the pressurizing channel 311 and the third internal thread 3121 on the inner wall of the upper end of the liquid suction channel 312, it is convenient for the user to simply screw the external pressurizing tube and the external liquid suction tube into the corresponding channels respectively to complete the connection, improving the operation efficiency.

[0044] Please refer to Figures 4 to 8 In one embodiment, the connector 3 includes a main body portion 31 and a connecting sleeve 32. The connecting sleeve 32 is rotatably sleeved outside the lower end of the main body portion 31. The lower end of the connecting sleeve 32 is threadedly sleeved outside the opening 11 of the packaging container 1. The main body portion 31 is provided with a pressurizing channel 311 and a liquid suction channel 312 that penetrate up and down. The connecting sleeve 32 is a rotatable component sleeved outside the lower end of the main body portion 31. Its main function is to provide a threaded connection with the opening 11 of the packaging container 1. By rotating the connecting sleeve 32, the connector 3 can be firmly fixed on the opening 11 of the packaging container 1, making the installation and disassembly of the connector 3 very simple, and only by rotating the connecting sleeve 32 can it be completed. Among them, a plurality of vertical anti-slip stripes 322 are circumferentially provided on the outer wall of the connecting sleeve 32. The anti-slip stripes 322 can significantly increase the friction force on the outer wall of the connecting sleeve 32, enabling the user to hold and apply force more stably when rotating the connecting sleeve 32.

[0045] Please refer to Figure 2 and Figures 6 to 11, in one embodiment, a straw connection portion 313 is provided at the bottom of the main body portion 31. A first accommodation cavity 33 is formed between the straw connection portion 313 and the connection sleeve 32 for the opening 11 and the straw 2 to enter. The first accommodation cavity 33 provides space for the installation of the opening 11 of the packaging container 1 and the straw 2, and also facilitates their connection with the pressurization channel 311 and the liquid suction channel 312; the pressurization channel 311 and the liquid suction channel 312 extend from the top surface of the main body portion 31 to the bottom of the straw connection portion 313. The upper end of the straw 2 is connected to the straw connection portion 313 through a straw connector 4 to achieve the connection between the straw 2 and the pressurization channel 311 and the liquid suction channel 312. In this way, when an external pressurization tube injects gas into the pressurization channel 311, the gas can enter the inside of the straw 2 through the straw connector 4 and act on the liquid in the packaging container 1; and when it is necessary to suck the liquid, the liquid can enter the liquid suction channel 312 through the straw connector 4 and be sent out by an external liquid suction tube. By providing the straw connection portion 313, the main body portion 31 realizes a firm connection with the straw 2 in cooperation with the straw connection portion 313, ensuring that the straw 2 will not loosen or fall off during the liquid suction process, thus ensuring the smooth flow of the liquid.

[0046] Please refer to Figures 6 to 11 , in one embodiment, a connection port 3131 communicating with the liquid suction channel 312 is opened in the middle of the bottom of the straw connection portion 313. The top of the straw connector 4 is provided with a second accommodation cavity 41 for the lower end of the straw connection portion 313 to be inserted, and the second accommodation cavity 41 communicates with the liquid suction channel 312. A pressurization tube 42 is provided in the middle of the second accommodation cavity 41. The upper end of the pressurization tube 42 is inserted into the connection port 3131. The outer diameter of the upper outer wall of the straw connector 4 is larger than the outer diameter of the lower outer wall of the straw connector 4. The upper end of the straw 2 is sleeved outside the upper outer wall of the straw connector 4. A plurality of liquid suction ports 43 communicating with the second accommodation cavity 41 are circumferentially opened on the lower outer wall of the straw connector 4. Among them, the connection port 3131 and the pressurization tube 42 are the key connection points between the pressurization channel 311 and the straw 2. When an external pressurization tube injects gas into the pressurization channel 311, the gas can enter the packaging container 1 through the pressurization tube 42 to form the required air pressure difference to drive the suction of the liquid. The second accommodation cavity 41 not only provides space for the insertion of the straw connection portion 313 but also ensures a firm connection between the two. At the same time, the second accommodation cavity 41 communicates with the liquid suction channel 312, enabling the liquid to enter the second accommodation cavity 41 from the straw 2 through the liquid suction ports 43 and then enter the liquid suction channel 312 through the second accommodation cavity 41. By setting the outer diameter of the upper outer wall of the straw connector 4 to be larger than the outer diameter of the lower outer wall of the straw connector 4, it is avoided that the upper end of the straw 2 blocks the liquid suction ports 43 opened on the lower outer wall of the straw connector 4 when it is sleeved outside the upper outer wall of the straw connector 4.

[0047] Please refer to Figure 7 , Figure 8, in one embodiment, a first sealing ring 34 is provided between the inner wall of the straw connector 4 and the outer wall of the straw connecting portion 313, and a second sealing ring 35 is provided between the inner wall of the connection port 3131 and the outer wall of the pressurizing tube 42. By introducing the first sealing ring 34 and the second sealing ring 35, the sealing performance between the straw connector 4 and the straw connecting portion 313 and between the connection port 3131 and the pressurizing tube 42 is further enhanced, preventing liquid or gas from leaking at the connection between the straw connector 4 and the straw connecting portion 313 and at the connection between the connection port 3131 and the pressurizing tube 42.

[0048] Please refer to Figure 2 , in one embodiment, an inclined cut 21 is provided at the bottom end of the straw 2. The inclined cut 21 can effectively prevent the problem of unsmooth liquid suction when the bottom of the straw 2 is in too tight contact with the bottom of the packaging container 1 due to manufacturing and assembly errors of parts. Moreover, the inclined cut 21 is conducive to ensuring less liquid residue in the packaging container 1 and saving costs.

[0049] Please refer to Figure 4 , Figure 5 , in one embodiment, the connector 3 is provided with two liquid suction channels 312 penetrating up and down, and the two liquid suction channels 312 are symmetrically arranged on both sides of the pressurizing channel 311. By providing the two liquid suction channels 312, the user can choose to use one liquid suction channel 312 for liquid suction, or choose to use the two liquid suction channels 312 for liquid suction simultaneously, accelerating the liquid suction effect; when the user chooses to use one liquid suction channel 312 for liquid suction, the other liquid suction channel 312 can be blocked by a sealing plug 5.

[0050] In one embodiment, the packaging container 1 is a barrel or a bottle.

[0051] In one embodiment, the straw 2 is a rigid straw. Compared with a soft straw 2, the rigid straw has better rigidity and stability. When sucking liquid, the rigid straw can maintain its shape unchanged, is not easily bent or deformed, thus ensuring the smoothness of liquid flow. In addition, the rigid straw also has high wear resistance and corrosion resistance, and can resist the erosion and wear of liquid to a certain extent. When used in cooperation with the connector 3, the rigid straw can be more firmly connected to the straw connector 4, reducing the leakage risk caused by the loosening or falling off of the straw 2. At the same time, the rigid straw can better withstand the suction force generated by the air pressure difference, ensuring that the liquid can be smoothly sucked out.

[0052] It should be understood that for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present utility model.

[0053] The above has given an exemplary description of the utility model patent in conjunction with the accompanying drawings. Obviously, the implementation of the utility model patent is not limited by the above-mentioned manner. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model patent.
