Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of atomic layer deposition experimental equipment, in particular to a pipeline component and a film coating device. Background Art
[0002] In the prior art, the pipeline assembly includes a spray structure and a three-way pipeline. The first and second pipelines in the three-way pipeline are respectively used to connect with two sources of reactants to be reacted, and then converge into the third pipeline in the three-way pipeline. At the same time, the other end of the third pipeline is connected to the spray structure and sprayed into the reaction chamber through the spray port of the spray structure for subsequent reaction.
[0003] However, the length of the third pipe mentioned above is relatively long. When the two reactants are sensitive to each other, it is easy for the two reactants to react quickly in the third pipe first. Long-term use will easily produce a deposited film in the third pipe, and the presence of the deposited film will block the third pipe, causing part of the reactants to be blocked by the deposited film during subsequent use and remain in the third pipe to continue reacting. This cycle will cause the entire experimental equipment to be unable to be used normally. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] In order to solve the problem in the prior art that the structure of the pipeline assembly is unreasonable, which causes the reactants to react prematurely in the third pipeline to produce a deposited film, in some embodiments, the utility model provides a pipeline assembly and a coating device, wherein the coating device includes a shell and a pipeline assembly, and the shell has a reaction chamber; at least the spray part 20 of the pipeline assembly is located in the reaction chamber, and the spray port 211 of the spray part 20 is connected to the reaction chamber, so that each reactant can flow into the flow chamber of the spray part 20 in only one direction through the corresponding pipeline structures 10, and be sprayed into the reaction chamber through the spray port 211 for reaction; wherein the pipeline assembly is the pipeline assembly mentioned above and below.
[0023] like Figure 1 As shown, the pipeline assembly includes multiple pipeline structures 10 and a spray part 20. The first ends of the multiple pipeline structures 10 are respectively used to communicate with the source of the reactant to be reacted; the spray part 20 has a flow cavity, a spray port 211, and a connecting port 212. The spray port 211 and the connecting port 212 are both connected to the flow cavity. There are multiple connecting ports 212, and the second ends of the multiple pipeline structures 10 are respectively connected to the multiple connecting ports 212 one by one; wherein, each connecting port 212 is provided with a one-way valve structure.
[0024] In some embodiments, a pipeline assembly is provided, in which the first ends of multiple pipeline structures 10 are respectively used to connect with the source of the reactant, and the second ends of the multiple pipeline structures 10 are respectively connected with the multiple connecting ports 212 of the spray part 20 in a one-to-one correspondence. Since a one-way valve structure is provided at each connecting port 212, each reactant flows into the flow cavity in only one direction through the corresponding pipeline structure 10 and is sprayed out through the spray port 211. The reactant will not react prematurely in the pipeline structure 10, and the deposition film will not be generated, thereby ensuring that each pipeline structure 10 will not be blocked by the deposition film.
[0025] It should be noted that, as a possible scenario, the first ends of multiple pipeline structures 10 are respectively connected to multiple different sources of reactants.
[0026] It should be noted that, as a possible scenario, the spray port 211 and the communication port 212 are located on different surfaces of the spray portion 20. In this way, the overall structure of the spray portion 20 is ensured to be regular, and the reactants sprayed from the spray port 211 are prevented from being sprayed onto the pipe structure 10, thereby ensuring that the reactants sprayed from the spray port 211 can enter the reaction chamber as smoothly as possible to facilitate subsequent sufficient reaction.
[0027] It should be noted that, as a possible scenario, each pipeline structure 10 includes a main pipeline 11 and multiple branch pipelines 12, wherein the first end of the main pipeline 11 is connected to the source of the reactant; the first end of each branch pipeline 12 is connected to the second end of the main pipeline 11, there are multiple spray sections 20, and the multiple spray sections 20 are provided in a one-to-one correspondence with the multiple branch pipelines 12, and the second end of each branch pipeline 12 is connected to each communication port 212 on the corresponding spray section 20. This ensures that each pipeline structure 10 is independent and prevents the reactant from reacting prematurely within the pipeline structure 10.
[0028] It should be noted that, in a specific embodiment of the present application, Figure 1As shown, there are two pipeline structures 10, each pipeline structure 10 has a main pipeline 11 and two branch pipelines 12, and the two branch pipelines 12 of the same pipeline structure 10 are arranged in a Y shape with the main pipeline 11; there are two spray parts 20, each spray part 20 has two connecting ports 212, one of the two connecting ports 212 on the same spray part 20 is connected to the second end of a branch pipeline 12 of the first pipeline structure 10, and the other of the two connecting ports 212 on the same spray part 20 is connected to the second end of a branch pipeline 12 of the second pipeline structure 10, so that the two spray parts 20, the two branch pipelines 12 of the first pipeline structure 10, and the two branch pipelines 12 of the second pipeline structure 10 form a circular structure. In this way, while ensuring the regularity of the overall structure of the pipeline assembly, it is also possible to ensure the uniformity of the reactants sprayed into the reaction chamber.
[0029] like Figure 1 As shown, the spray section 20 is a cylindrical structure with multiple communication ports 212 disposed around the circumferential outer surface of the spray section 20. At least one axial end of the spray section 20 has a spray port 211 disposed on its end surface. Multiple spray ports 211 are provided, and the multiple spray ports 211 are spaced apart. This ensures that different reactants can be sprayed into the reaction chamber as quickly as possible through the multiple spray ports 211, thereby preventing the different reactants from remaining in the flow chamber for extended periods of time.
[0030] It should be noted that, as a possible scenario, the spray section 20 includes multiple groups of spray port groups, each of which includes one or more spray ports 211. When a spray port group includes one spray port 211, the spray port 211 is located at the geometric center of the spray section 20. When a spray port group includes multiple spray ports 211, the multiple spray ports 211 in the same group are spaced apart circumferentially around the spray section 20, and the multiple groups of spray port groups are spaced apart radially along the spray section 20. This ensures uniformity in the spray of the reactants from the spray section 20.
[0031] Preferably, the apertures of the multiple spray ports 211 in the same spray port group are equal.
[0032] Optionally, in the radial direction from the inside to the outside of the spray portion 20 , the number of the spray ports 211 in each spray port group gradually increases.
[0033] It should be noted that, in a specific embodiment of the present application, considering that the suction force in the middle of the spraying part 20 is greater than the suction force on the outer peripheral side, in order to further ensure the spraying effect of each spraying port 211 of the spraying part 20, as shown in FIG. Figure 1As shown, the aperture of at least the spray port 211 located at the geometric center of the spray portion 20 is smaller than the apertures of the other spray ports 211. In this way, when the reactant used in this application is a gas, the gas sprayed through all the spray ports 211 can be evenly dispersed into the reaction chamber.
