[0027] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] With the continuous development of electronic technology, uniformly covering the substrate with a film layer is a commonly used technology.

[0030] In general, existing electronic devices tend to be miniaturized and thin, so it is very important to accurately attach a fixed thickness, relatively thin film layer on the substrate. In related technologies, vapor deposition technology can achieve the above-mentioned effect of attaching a thin, precise thickness film layer on the substrate. For example, in order to make the luminous color of the display panel more accurate and reduce the color deviation of the display panel, a thin film encapsulation process for generating a CVD film layer, that is, the above-mentioned vapor deposition technology, can be used to prepare a CVD film with the required refractive index between the optical functional layer and the thin film encapsulation layer of the display panel, so that the light emitted by the optical functionality can be free of color deviation, and ultimately the display of the display panel is more accurate.

[0031] like Figure 1 and Figure 2 As shown, Figure 1 This is the side cross-sectional view corresponding to the vapor deposition equipment. Figure 2 It is a three-dimensional diagram of part of the structure of the vapor deposition equipment. Figure 1 It can be seen that the vapor deposition equipment includes two electrodes, a lower electrode 11 and a back electrode 12, and a gas reactor 13 is arranged below the back electrode 12, wherein the back electrode 12 and the gas reactor 13 need to be relatively suspended and electrically connected, and therefore, are connected through an electrical connection sheet 14. Furthermore, a placement space 15 for placing a substrate waiting to be deposited with a film layer by the vapor deposition equipment is provided between the gas reactor 13 and the lower electrode 11. During the vapor deposition process, a substrate (for example, a substrate of a display panel) can be placed in the placement space 15, and the gas ions are separated by the electrolysis of the gas by the vapor deposition equipment, and finally the separated ions cover the substrate to form a film layer.

[0032] Further, by Figure 2 As shown, in Figure 2 Figure 1 shows a three-dimensional stereoscopic image of the back electrode 12, gas reactor 13, and electrical connection sheet 14. It can be seen that the back electrode 12 and gas reactor are electrically connected via a very thin, surrounding hollow sheet 14 and are suspended relative to each other. Specifically, during the actual vapor deposition process, both the back electrode 12 and gas reactor 13 are provided with a number of uniform pores. To ensure uniform gas reaction and coverage, gas is introduced through the central pores of the back electrode 12, passes through the hollow region of the sheet 14, reaches the gas reactor, and then electrolyzes the gas. The electrolyzed gas ions are then evenly distributed above the substrate through the pores of the gas reactor 13, forming a film layer.

[0033] As the temperature in the placement space 15 continues to rise as the coating process proceeds, the temperature of the gas reactor 13 will also rise accordingly. As the temperature of the gas reactor 13 rises, the electrolysis rate and the film formation rate of the substrate will continue to accelerate.

[0034] like Figure 3 As shown, Figure 3 As can be seen from line A in the figure, as the temperature rises, the gas reactor 13 causes the film formation rate of the substrate to continue to increase. In the case where the substrate is a substrate of a display panel, the thickness of the film layer may eventually be thicker than the required thickness, affecting the accuracy of the color displayed by the display panel.

[0035] Based on this, the present application proposes a vapor deposition device that can solve the problem that the vapor deposition technology will make the speed of generating film layers faster and faster over time, which may cause the thickness of the generated film layer to be thicker than the required thickness, thereby affecting the use effect of the substrate, ensuring the stability of the film thickness, and improving the reliability of the film layer on the substrate.

[0036] like Figure 4 As shown, Figure 4 This is a vapor deposition device according to an embodiment of the present application, characterized in that the device includes: a first electrode and a second electrode arranged opposite to each other, a gas uniformizer is arranged on the side of the first electrode close to the second electrode, a first space is arranged between the gas uniformizer and the second electrode, the first space is used to arrange a substrate, and a temperature control plate is arranged on the side of the first electrode away from the second electrode.

[0037] Illustratively, the first electrode may be an electrode in a vapor deposition device for delivering gas to a gas homogenizer and generating an electric field between the electrode and the gas homogenizer.

[0038] Illustratively, the areas of the first electrode and the second electrode may be the same.

[0039] Illustratively, the area of ​​the first electrode and the area of ​​the second electrode may be the same as or different from the area of ​​the substrate disposed in the first space.

[0040] It is understood that the above-mentioned vapor deposition equipment is used to coat substrates, and generally, the coating of the substrate should be of a fixed and uniform thickness. At the same time, the vapor deposition equipment often needs to coat multiple different substrates during the operating time. In the process of coating each substrate, in order to ensure uniform film thickness and accurate fixation of the film thickness, the area of ​​the substrate and the first electrode and the area of ​​the second electrode are set to be the same as the area of ​​the substrate placed in the first space. This allows the same substrate to be coated at a time, with high speed and high accuracy.

[0041] In an example, the first electrode may be a backing plate.

[0042] In one example, the second electrode may be a bottom electrode (Susceptor).

[0043] Exemplarily, the gas homogenizer is used to electrolyze the gas and uniformly transport the electrolyzed gas ions to attach to the surface of the substrate.

[0044] In one example, the gas homogenizer may be a gas reactor (Diffuser).

[0045] In the embodiment of the present application, the first electrode and the gas homogenizer are arranged opposite to each other and are respectively attached to the end surfaces on both sides of the connecting member, wherein the connecting member is a heat conducting member.

[0046] Illustratively, a first space for arranging a substrate is provided between the gas homogenizer and the second electrode.

[0047] It can be understood that the substrate is a substrate to be coated, that is, a substrate to be covered with a film layer by vapor deposition.

[0048] Furthermore, the range of the first space is related to the thickness and duration of the substrate to be coated, and is an adjustable space size.

[0049] For example, if the user requires the substrate to be coated in a shorter time, the first space can be set to be smaller, that is, the distance between the gas reactor and the second electrode can be set closer. For another example, if the user requires the substrate coating to be thinner and the film thickness to be more accurate, the first space can be set to be larger, that is, the distance between the gas reactor and the second electrode can be set to be farther. This embodiment of the present application does not limit this.

[0050] Exemplarily, a temperature control plate may be provided on a side of the first electrode away from the second gas electrode and the gas homogenizer.

[0051] In one example, the temperature control plate is a non-electric cooling structure with a plurality of temperature control pipelines arranged on a side away from the second electrode.

[0052] In one example, the temperature control plate may include several temperature control pipelines arranged on the side away from the second electrode, and the temperature control plate may be provided with an electric cooling structure of a power pump and a cooling system outside the area where the vapor deposition equipment is located.

[0053] Furthermore, in the case where the above-mentioned temperature control plate is an electric cooling structure, by starting the temperature control plate, the temperature control plate continuously circulates the heat-conducting liquid in the temperature control pipeline through the power pump, and at the same time transmits the heat-conducting liquid that has absorbed heat and heated up to the cooling system for cooling, and then transmits it to the temperature control pipeline and the first temperature control pipeline again for cooling the first electrode and the gas homogenizer respectively.

[0054] In the embodiment of the present application, the first electrode is arranged opposite to the gas homogenizer and is electrically connected to the gas homogenizer through a connector.

[0055] Exemplarily, the connecting member is an electrode transmission path between the first electrode and the gas homogenizer.

[0056] It is understood that in order to achieve vapor deposition, the principle of vapor deposition is to electrolyze a gas through the electrolysis between the gas homogenizer and the first electrode, thereby separating the gas into ions. The target ions are then attached to the substrate surface through the interaction of the first and second electrodes to form a film layer. Therefore, the connector needs to serve as an electrical connector between the first electrode and the gas homogenizer to enable the first electrode and the gas homogenizer to complete the electrolysis of the gas.

[0057] In an embodiment of the present application, the connecting member includes at least one hollow structure, and the orthographic projection of the at least one hollow structure in the middle area of ​​the first electrode is within the orthographic projection of the gas homogenizer.

[0058] It is understood that the connector is used to isolate the gas homogenizer and the first electrode, so that they are suspended, that is, they are separated by a certain distance while also having an isolated space. Based on this, the gas homogenizer and the first electrode can be separated by a heat conducting member located between the gas homogenizer and the first electrode. At the same time, the connector has a hollow structure, so that there is a certain isolated space between the gas homogenizer and the first electrode.

[0059] Exemplarily, the above-mentioned hollow structure may be one hollow structure or multiple central control structures.

[0060] It can be understood that, in order to enable the ions decomposed from the gas to uniformly adhere to the substrate in the first space, when the hollow structure is a single hollow structure, it is necessary to make the gas and the ions decomposed from the gas uniformly output from the central region of the first backplane to the space isolated between the gas homogenizer and the first electrode, and then the gas electrolysis reaction occurs uniformly; when the hollow structure is multiple hollow structures, each of the multiple hollow structures can be the same. In this way, it is also possible to make the gas and the ions decomposed from the gas uniformly output from the central region of the first backplane to the space isolated between the gas homogenizer and the first electrode, and then the gas electrolysis reaction occurs uniformly.

[0061] For example, the multiple hollow structures can be a hollow structure in the form of a Chinese character "tian" composed of 4 frame structures.

[0062] In the embodiments of the present application, the first electrode and the gas homogenizer are respectively and adhesively disposed on the end faces on both sides of the connecting member, and / or a first temperature control pipeline communicating with the temperature control pipeline in the temperature control plate is disposed in the outer region of the projection area of the connecting member on the gas homogenizer on the side of the gas homogenizer close to the first electrode.

[0063] It can be understood that, in order to ensure the constant temperature of the gas homogenizer: Method 1: The connecting member can be set as a connecting member with two end faces, so that the first electrode and the gas homogenizer are respectively adhered to it for cooling; Method 2: The gas homogenizer is cooled by providing a first temperature control pipeline communicating with the temperature control pipeline in the temperature control plate on the surface of the gas homogenizer.

[0064] Furthermore, the above two methods can be used together, or only one of them can be used. The following is an explanation in turn:

[0065] Method 1: The first electrode and the gas homogenizer are respectively and adhesively disposed on the end faces on both sides of the connecting member.

[0066] Exemplarily, the end faces on both sides of the connecting member in contact with the first electrode and the gas homogenizer have a certain contact area.

[0067] Furthermore, the end face of the connecting member in contact with the first electrode and the end face of the connecting member in contact with the gas homogenizer can have the same area or different areas.

[0068] Still further, the shapes of these two end faces can be the same or different.

[0069] Exemplarily, the above-mentioned connecting member is used to heat-conduct the heat received by the gas homogenizer in the first space to the first electrode, or directly dissipate it to the area where the vapor deposition equipment is located, so that the temperature change of the gas homogenizer is within a preset range, or the temperature change rate of the gas homogenizer is significantly reduced.

[0070] Optionally, the connecting member is made of a heat-conducting metal material.

[0071] It is understandable that as a connector, it has both heat conduction and electrical connection functions. Therefore, it needs to be set to a heat-conducting metal material to achieve the above-mentioned heat conduction and electrical connection functions.

[0072] It can be understood that, when the connecting member with end surfaces on both sides conducts heat from the gas homogenizer to the first electrode, the heat of the first electrode will also increase accordingly.

[0073] Furthermore, generally, the operating temperature range corresponding to the electrolysis work of the first electrode is larger. Therefore, the first electrode is not easily affected by temperature changes and its working efficiency is affected. However, in order to prevent the temperature of the first electrode from exceeding the operating temperature range and ultimately affecting the normal working mode of the vapor deposition equipment, a temperature control plate can be set for the first electrode, and the temperature of the first electrode can be adjusted in time through the above-mentioned temperature control plate.

[0074] like Figure 4 and Figure 5 As shown, Figure 4 is a side cross-sectional view corresponding to the vapor deposition apparatus in the embodiment of the present application, Figure 5 It is a three-dimensional stereogram of part of the structure of the vapor deposition equipment in the embodiment of this application. Figure 4 As can be seen, the vapor deposition apparatus includes two electrodes: a lower electrode 31 (also known as the second electrode) and a back electrode 32 (also known as the first electrode). A gas reactor 33 (also known as the gas homogenizer) is located below the back electrode 32, on the side of the back electrode 32 closest to the lower electrode 31. A first space 34 is located between the gas reactor 33 and the lower electrode 31, specifically for placing the substrate on which the film layer will be formed during the vapor deposition process.

[0075] Furthermore, a hollow structure needs to be provided between the back electrode 32 and the gas reactor 33, so that the two are suspended from each other and need to be electrically connected. At the same time, since the gas reactor 33 is easily affected by the heat generated by the first space 34 during the vapor deposition process, a connector 35 with two end faces is provided between the gas reactor 33 and the back electrode 32, wherein the connector 35 is a heat conduction member, and the two end faces of the connector 35 are respectively attached to the back electrode 32 and the gas reactor 33, so that the gas reactor 33 can transfer heat through the end face of the connector 35 attached to it to the other end face of the connector 35 attached to the back electrode 32, and finally transfer the heat to the back electrode 32.

[0076] like Figure 5 As shown in the three-dimensional stereogram of the back electrode 32, the gas reactor 33 and the connecting piece 35, it can be seen that the back electrode 32 and the gas reactor 33 are electrically connected through the connecting piece 35. At the same time, the connecting piece 35 has a hollow structure 36. The hollow structure 36 is within the range of the positive projection of the gas reactor 33 in the middle area of ​​the back electrode 32.

[0077] Optionally, in an embodiment of the present application, the contact area between the connector and the gas homogenizer is greater than a preset area, so that the heat conduction rate corresponding to the connector matches the heat generation rate of the substrate.

[0078] It is understood that in order to prevent the gas reactor from being affected by temperature changes in the first space, that is, to enable the gas reactor to maintain a stable temperature, thereby ensuring that the film formation rate is uniform and constant within a controllable range, it is necessary to set the contact area between the connector and the contact end surface of the gas homogenizer to be larger than a preset area, wherein the preset area can match the heat conduction rate corresponding to the connector with the heat generation rate of the substrate to be vapor deposited. Specifically, the preset area can match the heat conduction rate corresponding to the connector with the heat generation rate of the first space where the substrate to be vapor deposited is located.

[0079] Furthermore, the contact area between the connecting member and the first electrode may be larger than the first preset area, so that the heat conduction rate corresponding to the connecting member matches the heat generation rate of the gas reactor.

[0080] like Figure 3 As shown by line B in FIG, as the time length increases, the temperature of the substrate in the actual first space also increases, which in turn causes the gas reactor to be affected by the temperature in the first space and increase in temperature. However, since the two side end surfaces are respectively attached to Figure 4The connecting piece 35 on the back electrode 32 and the gas reactor 33, and the heat conduction rate corresponding to the connecting piece 35 matches the heating rate of the substrate. Therefore, the heat received by the gas reactor 33 will be directly conducted upward to the back electrode 32 through the connecting piece 35, and will not remain in the gas reactor 33. Figure 3 The temperature of the gas reactor 33 indicated by the line B will remain constant, which will not affect the film forming rate of the substrate in the first space, and can also ensure that the film thickness of the substrate in the first space remains unchanged over time.

[0081] Method 2: A first temperature control pipeline connected to the temperature control pipeline in the temperature control plate is provided on the side of the gas homogenizer close to the first electrode and outside the area of ​​the connector on the positive projection of the gas homogenizer.

[0082] It is understandable that, in order to ensure that the temperature of the gas homogenizer is sufficiently stable, a first temperature control pipeline connected to the temperature control pipeline may be provided on a side of the gas homogenizer close to the first electrode.

[0083] Furthermore, since the temperature of the temperature control pipeline in the temperature control plate can be controlled, the temperature of the first temperature control pipeline connected to the temperature control pipeline of the temperature control plate can also be controlled. When the temperature of the first temperature control pipeline can be controlled, the temperature of the gas homogenizer can be controlled by controlling the temperature of the first temperature control pipeline.

[0084] It should be noted that since a gas electrolysis reaction between the first electrode and the gas homogenizer can occur in at least one hollow structure of the connector, a high-density electric field is present in the at least one hollow structure. Therefore, the first temperature control pipeline can be arranged in an area outside the high-density electric field, that is, in an area outside the positive projection area of ​​the connector on the gas homogenizer.

[0085] like Figure 6 and Figure 7 As shown, Figure 6 is a side view of the vapor deposition equipment. Figure 7 It is a three-dimensional stereoscopic diagram corresponding to the vapor deposition equipment. The first temperature control pipeline 71 is connected to the temperature control pipeline 73 of the temperature control plate 72, and is arranged on the side of the gas reactor 33 close to the back electrode 32. Specifically, it is arranged in the outer area 74 of the connecting part 35 in the positive projection area of ​​the above-mentioned gas reactor 33.

[0086] In the present application, the vapor deposition equipment includes a first electrode and a second electrode arranged opposite to each other, wherein a gas homogenizer is arranged on the side of the first electrode close to the second electrode, a first space for arranging a substrate is provided between the gas homogenizer and the second electrode, and a temperature control plate is provided on the side of the first electrode away from the second electrode; further, the first electrode and the gas homogenizer are arranged opposite to each other and are electrically connected through a connector, the connector includes at least one hollow structure, and the at least one hollow structure is within the orthographic projection of the gas homogenizer in the middle area of ​​the first electrode; wherein the first electrode and the gas homogenizer are respectively arranged on the end surfaces on both sides of the connector, and / or a first temperature control pipeline connected to the temperature control pipeline in the temperature control plate is provided on the side of the gas homogenizer close to the first electrode and in the outer area of ​​the connector on the orthographic projection area of ​​the gas homogenizer. In this way, the first electrode and the gas homogenizer are connected through a connector with an end face, so that the heat in the gas homogenizer can be conducted and dissipated through the end face of the heat conduction member, or the temperature of the gas homogenizer can be kept constant through the first temperature control pipeline, thereby greatly reducing the temperature change rate of the gas homogenizer caused by the temperature rise of the first space, keeping the temperature of the gas homogenizer stable, and thus ensuring that the temperature of the vapor deposition equipment is stable during the process of vapor deposition to generate a film layer, the thickness of the film layer is consistent, and the subsequent use effect of the substrate is good.

[0087] Optionally, in an embodiment of the present application, the above-mentioned connecting member includes at least one closed annular structure, and the above-mentioned closed annular structure includes: an annular support structure, a first end face and a second end face, and the first end face is provided on the side of the above-mentioned annular support structure perpendicular to the above-mentioned first electrode, and the second end face is provided on the side of the above-mentioned annular support structure perpendicular to the above-mentioned gas uniformizer.

[0088] Illustratively, the first end surface is in contact with the first electrode, and the second end surface is in contact with the gas homogenizer.

[0089] Illustratively, the orthographic projection shape of the annular support structure on the gas homogenizer may include a variety of annular shapes, which is not limited in the embodiment of the present application.

[0090] In one example, the annular shape may be a circle, a square, or other polygons, such as a regular hexagon, a regular pentagon, a rhombus, etc., which is not limited in the embodiment of the present application.

[0091] Furthermore, the annular support structure of the above-mentioned connecting member may include one annular support structure or multiple annular support structures, which is not limited in the embodiments of the present application.

[0092] For example, Figure 5 As shown, in Figure 5, the ring shape is a single four-bordered rectangle.

[0093] Furthermore, the annular shape may be a four-frame rectangle, and the closed annular structure may be a frame structure corresponding to the four four-frame rectangles. Specifically, the connecting member may be a grid-shaped frame structure.

[0094] Optionally, in an embodiment of the present application, a plurality of connection holes are provided in the temperature control plate and in the area corresponding to the first electrode and the outer area.

[0095] Exemplarily, the diameter of the connecting hole is greater than or equal to the diameter of the first temperature control pipeline;

[0096] Exemplarily, the first temperature control pipeline is: the temperature control pipeline of the temperature control plate extends from the connection hole to the side of the gas homogenizer close to the first electrode, and is fitted onto the side of the gas homogenizer close to the first electrode.

[0097] For example, Figure 7 As shown, in Figure 7 It can be seen that a plurality of connection holes 75 are provided in the temperature control plate 72 and the area corresponding to the back electrode 32 and the outer area 74 . The apertures of these connection holes are greater than or equal to the aperture of the first temperature control pipeline 71 .

[0098] Specifically, the first temperature control pipeline 71 is a pipeline connected to the temperature control pipeline 73 in the temperature control plate 72.
