[0036] See also Figure 1 , Figure 1 Schematic diagram of the structure of the solid precursor packaging device in the first embodiment of the utility model, the solid precursor packaging device includes: a bottle body 100, an air inlet pipe 200, an air outlet pipe 300 and a path extension member 400.
[0037] The bottle body 100 is used to encapsulate the precursor.
[0038] The air inlet pipe 200 is passed through the bottle body 100 , and one end of the air inlet pipe 200 toward the bottle body 100 extends into the bottle body 100 . The end of the air inlet pipe 200 away from the bottle body 100 is used to communicate with the air supply end of a preset gas supply device.
[0039] The gas outlet pipe 300 is disposed in the bottle body 100 , and one end of the gas outlet pipe 300 extends into the bottle body 100 . The end of the gas outlet pipe 300 away from the bottle body 100 is used to communicate with a reaction chamber of a preset vapor deposition device.
[0040] The path extension member 400 is disposed in the bottle body 100 , and the path extension member 400 is used to change the flow direction of the carrier gas flowing into the bottle body 100 from the air inlet pipe 200 , and the carrier gas is used to carry the precursor into the reaction chamber.
[0041] Through the above embodiment, when the staff starts the vapor deposition equipment, the air inlet pipe 200 of the solid precursor packaging device is connected to the gas supply end of the gas supply device, and the air outlet pipe 300 of the solid precursor packaging device is connected to the reaction chamber of the vapor deposition equipment. The carrier gas flowing out of the gas supply device enters the bottle body 100 through the air inlet pipe 200 of the solid precursor packaging device, and is guided by the path extension member 400 to change the flow direction of the carrier gas from the longitudinal flow direction of the air inlet pipe 200 to the lateral flow direction, and finally flows out to the process pipeline of the vapor deposition equipment through the air outlet pipe 300 of the solid precursor packaging device. During the transmission process inside the bottle body 100, the path extension member 400 is provided to change the flow direction of the carrier gas inside the bottle body 100, thereby increasing the time the carrier gas stays in the bottle body 100. The lateral and longitudinal flows of the carrier gas in the bottle body 100 make the carrier gas transmission more uniform, thereby ensuring the stability of the solid precursor output, extending the carrier gas flow path, and increasing the contact area between the carrier gas and the solid precursor, thereby improving the problem of unstable vapor pressure of the solid precursor in the solid precursor packaging device, thereby improving the stability of the vapor deposition process and the equipment utilization rate, while reducing the production cost.
[0042] In one embodiment, Figure 1 and Figure 2 As shown, the air inlet pipe 200 and the air outlet pipe 300 are coaxially arranged on the bottle body 100, the length of the air outlet pipe 300 extending toward the inside of the bottle body 100 is greater than the length of the air inlet pipe 200 extending toward the bottle body 100, one end of the air inlet pipe 200 extending toward the bottle body 100 extends to the middle position of the bottle body 100, and one end of the air outlet pipe 300 extending toward the bottle body 100 extends to the bottom of the bottle body 100 and has a gap with the bottom of the bottle body 100.
[0043] It is worth mentioning that, since the existing packaging containers are arranged on both sides of the top of the container wall, the air inlet pipe 200 and the air outlet pipe 300 are difficult to identify in shape. When replacing the precursor packaging container, the operator may not be able to clearly identify the air inlet pipe 200 and the air outlet pipe 300 due to negligence. The solid-state precursor packaging device provided in this embodiment can avoid the phenomenon of the air inlet pipe 200 and the air outlet pipe 300 being connected reversely by coaxially arranging the air inlet pipe 200 and the air outlet pipe 300.
[0044] Furthermore, the enlarged diameter of the air inlet pipe 200 can increase the contact area between the carrier gas entering the packaging container and the precursor in the horizontal direction. However, the conventional air inlet pipe 200 is arranged at a position far away from the air outlet pipe 300 at the top of the packaging container. As the precursor is used and consumed, even if the diameter of the air inlet pipe 200 is enlarged, there is a high probability that channeling will occur inside the solid precursor. The air inlet pipe 200 of the solid precursor packaging device provided in this embodiment is arranged outside the air outlet pipe 300 and distributed at the top center of the packaging container, which not only ensures that the air inlet pipe 200 has a larger air inlet pipe 200 diameter, increases the contact area between the carrier gas entering the packaging container and the precursor in the horizontal direction, but also avoids the channeling phenomenon of the solid precursor. In addition, the air inlet pipe 200 and the air outlet pipe 300 are arranged at a position at the top of the packaging container, which can simplify the packaging container preparation process and reduce the process processing cost.
[0045] Through the above-mentioned embodiment, the bottle body 100 can fully flow inside the bottle body 100 under the obstruction of the path extension member 400, and finally be transmitted to the reaction chamber of the vapor deposition equipment through the gas outlet pipe 300. The path extension member 400 continuously changes the flow direction of the carrier gas inside the bottle body 100, so that the carrier gas is fully mixed with the precursor, so that the carrier gas in the flow process can be fully mixed with the precursor through a longer path and then transmitted to the vapor deposition equipment.
[0046] In one embodiment, Figure 1 and Figure 2 As shown, a fixing member 440 is provided on the inner wall of the bottle body 100, and one end of the fixing member 440 away from the inner wall of the bottle body 100 is connected to the path extension member 400. The connection method between the path extension member 400 and the fixing member 440 can be a fixed connection or a detachable connection, so that the path extension member 400 can stably change the flow direction of the carrier gas. This is not limited in the present embodiment, and the fixing member 440 can be fixedly connected to the inner wall of the bottle body 100 at one end away from the path extension member 400, or fixedly connected to the side wall of the bottle body 100.
[0047] In one embodiment, Figure 1-Figure 4 As shown, the path extension member 400 includes an air intake baffle 410, which is used to change the air intake direction of the air intake pipe 200. The connection method between the air intake baffle 410 and the bottle body 100 can be a fixed connection or a detachable connection. The connection method between the air intake baffle 410 and the bottle body 100 is not limited here. In this embodiment, the air intake baffle 410 is set at the air outlet of the air intake pipe 200 in a fixed connection manner.
[0048] Through the above-mentioned embodiment, the provision of the air inlet baffle 410 changes the direction of the carrier gas flow in the air inlet pipe 200, and the carrier gas is guided into other areas in the bottle body 100 through the air inlet baffle 410, so that the carrier gas and the precursor in the bottle body 100 are fully mixed. By extending the time of the carrier gas in the bottle body 100, the flow direction of the carrier gas is further changed horizontally and vertically through the air inlet baffle 410, so that the precursor is evenly distributed inside the bottle body 100 under the guidance of different wind directions, thereby improving the uniformity of mixing of the carrier gas and the precursor.
[0049] In one embodiment, Figure 1 and Figure 2 As shown, the path extension member 400 also includes a partition 420, which is used to change the flow direction of the carrier gas guided by the air intake partition 420. The partition 420 is fixedly connected to the inner wall of the bottle body 100, and the partition 420 is vertically arranged along the corresponding guide of the air intake baffle 410.
[0050] Furthermore, a ventilation portion 500 is provided on the partition plate 420 , and the ventilation portion 500 is used to change the flow direction of the carrier gas. In the present embodiment, the ventilation portion 500 may be a ventilation hole or a mesh plate.
[0051] Through the above embodiment, the carrier gas moves to the partition 420 under the guidance of the air inlet baffle 410, and the partition 420 blocks and guides the carrier gas that changes from longitudinal flow to transverse flow again, so that the transversely flowing carrier gas is again divided into the longitudinal carrier gas flowing along the partition 420 and the transverse carrier gas directly formed through the vent holes on the ventilation part 500 or the mesh holes on the mesh plate. The setting of the partition 420 further increases the flow direction of the carrier gas inside the bottle body 100, so that the precursor concentration inside the bottle body 100 is more uniform.
[0052] In one embodiment, Figure 3 As shown, a plurality of partitions 420 may be arranged in the bottle body 100, and the partitions 420 are arranged in sequence along the carrier gas flow guided by the air inlet baffle 410, and the height of the partitions 420 decreases with the flow direction of the carrier gas guided by the air inlet baffle 410, and the distance between adjacent partitions 420 increases with the distance of the air inlet pipe 200; partitions 420 are arranged in sequence on one side of the air outlet pipe 300 inside the bottle body 100, and when the number of partitions 420 is 1, a vent 500 is arranged on the partition 420 near the bottom of the bottle body 100; when the number of partitions 420 is greater than 1, except for the partition 420 near the air outlet pipe 300, the vent 500 is not arranged, and the other partitions 420 are arranged near the bottom of the bottle body 100. The vent 500 is a vent hole or a mesh plate, and the height of the partition 420 gradually decreases.
[0053] In one embodiment, Figure 4As shown, a plurality of baffles 420 may be provided in the bottle body 100, and the baffles 420 are sequentially arranged along the flow direction of the carrier gas guided by the air inlet baffle 410, the height of the baffles 420 decreases with the flow direction of the carrier gas guided by the air inlet baffle 410 (i.e., the height H gradually decreases along the direction away from the air inlet pipe 200), and the distance between adjacent baffles 420 increases with the distance from the air inlet pipe 200 (i.e., the distance L gradually increases along the direction away from the air inlet pipe 200), and the air outlet pipe inside the bottle body 100 is located at a position adjacent to the baffle 420. The partitions 420 with symmetrical distribution of height are symmetrically arranged on both sides of 300. When the number of the partitions 420 on one side is 1, the partitions 420 are provided with a vent 500 near the bottom of the bottle body 100; when the number of the partitions 420 on one side is greater than 1, except that the partitions 420 near the air outlet pipe 300 are not provided with the vent 500, the other partitions 420 are provided with a vent 500 near the bottom of the bottle body 100, which is a vent hole or a mesh plate, and the height of the partitions 420 on one side gradually decreases.
[0054] Through the above embodiments, when the packaging device is connected to the vapor deposition equipment, the air inlet pipe 200 is connected to the air inlet end of the vapor deposition equipment, and the air outlet pipe 300 is connected to the process pipeline of the vapor deposition equipment. The carrier gas enters the bottle body 100 through the air inlet pipe 200, and is redirected in the lateral direction through the air inlet baffle 410 to form lateral and longitudinal carrier gas transmission. After the carrier gas flows through the area with the vent 500, it is reversely transmitted from the vent 500 to reflux through the solid precursor, and then flows out through the air outlet pipe 300 to enter the process pipeline of the vapor deposition equipment. During the transmission of the solid precursor and the inside of the bottle cavity, the height of the baffle decreases and the cavity area increases in the lateral direction, thereby ensuring the uniformity of the carrier gas transmission in the direction away from the center of the air outlet pipe 300, thereby ensuring the output stability of the precursor, extending the carrier gas flow path, and increasing the contact area between the carrier gas and the solid precursor, thereby improving the problem of unstable precursor vapor pressure in the container body, improving the stability of the vapor deposition process and the equipment utilization rate, and reducing the production cost.
[0055] In one embodiment, Figure 5 and Figure 6 As shown, the air inlet pipe 200 and the air outlet pipe 300 are arranged at relative positions on the top end of the bottle body 100 , and the path extension member 400 is arranged between the air inlet pipe 200 and the air outlet pipe 300 .
[0056] Through the above-mentioned embodiment, since the air inlet pipe 200 and the air outlet pipe 300 are relatively arranged on the top surface of the bottle body 100, and the path extension member 400 is arranged between the air inlet pipe 200 and the air outlet pipe 300, during the flow of the carrier gas, the carrier gas passes through a longer path in the bottle body 100, so that the carrier gas can fully carry the uniform precursor, and a path extension member 400 for increasing the flow distance of the carrier gas is also arranged between the air inlet pipe 200 and the air outlet pipe 300, which further increases the uniformity of the mixing of the carrier gas and the precursor.
[0057] In one embodiment, Figure 5 and Figure 6 As shown, the path extension piece 400 of the air inlet pipe 200 and the air outlet pipe 300 includes a plurality of partitions 420, which are arranged in sequence along the direction of the carrier gas flow guided by the air inlet baffle 410 and the height of the partitions 420 decreases with the direction of the carrier gas flow guided by the air inlet baffle 410, and the distance between adjacent partitions 420 increases with the distance of the air inlet pipe 200.
[0058] Through the above embodiments, when the packaging device is connected to the vapor deposition equipment, the air inlet pipe 200 is connected to the air inlet end of the vapor deposition equipment, and the air outlet pipe 300 is connected to the process pipeline of the vapor deposition equipment. The carrier gas enters the bottle body 100 through the air inlet pipe 200, and is redirected in the lateral direction through the air inlet baffle 410 to form lateral and longitudinal carrier gas transmission. After the carrier gas flows through the area with the vent 500, it is reversely transmitted from the vent 500 to reflux through the solid precursor, and then flows out through the air outlet pipe 300 to enter the process pipeline of the vapor deposition equipment. During the transmission of the solid precursor and the inside of the bottle cavity, the height of the baffle decreases and the cavity area increases in the lateral direction, thereby ensuring the uniformity of the carrier gas transmission in the direction away from the center of the air outlet pipe 300, thereby ensuring the output stability of the precursor, extending the carrier gas flow path, and increasing the contact area between the carrier gas and the solid precursor, thereby improving the problem of unstable precursor vapor pressure in the container body, improving the stability of the vapor deposition process and the equipment utilization rate, and reducing the production cost.
[0059] In one embodiment, Figure 5 and Figure 6 As shown, a reverse baffle 430 is further provided in the bottle body 100 , and the reverse baffle 430 and the partition 420 are arranged alternately, and a vent 500 is provided at one end of the reverse baffle 430 away from the air inlet pipe 200 .
[0060] Through the above embodiments, when the packaging device is connected to the vapor deposition equipment, the air inlet pipe 200 is connected to the air inlet end of the vapor deposition equipment, and the air outlet pipe 300 is connected to the process pipeline of the vapor deposition equipment. The carrier gas enters the bottle body 100 through the air inlet pipe 200, and is redirected in the lateral direction through the air inlet baffle 410 to form lateral and longitudinal carrier gas transmission. After the carrier gas flows through the area with the vent 500, it is reversely transmitted from the vent 500 to reflux through the solid precursor, and then flows out through the air outlet pipe 300 to enter the process pipeline of the vapor deposition equipment. During the transmission of the solid precursor and the inside of the bottle cavity, the height of the baffle decreases and the cavity area increases in the lateral direction, thereby ensuring the uniformity of the carrier gas transmission in the direction away from the center of the air outlet pipe 300, thereby ensuring the output stability of the precursor, extending the carrier gas flow path, and increasing the contact area between the carrier gas and the solid precursor, thereby improving the problem of unstable precursor vapor pressure in the container body, improving the stability of the vapor deposition process and the equipment utilization rate, and reducing the production cost.
