[0039] The invention will now be described more fully below with reference to the accompanying drawings, in which various embodiments are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth below. Rather, these embodiments are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of the invention to those skilled in the art. The same reference numerals throughout refer to the same elements.

[0040] Various modifications and forms may be made in this disclosure, and specific embodiments will be shown in the accompanying drawings and described in detail in the text. However, this is not intended to limit this disclosure to the specific forms disclosed, and it will be understood that all changes, equivalents, or substitutions falling within the spirit and technical scope of this disclosure should be included.

[0041] It will be understood that when an element is referred to as being "on" another element, it can be directly on that other element, or there can be an intermediate element between them. Conversely, when an element is referred to as being "directly" on another element, there is no intermediate element.

[0042] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or part from another. Therefore, the first element, component, region, layer, or part discussed below may be referred to as the second element, component, region, layer, or part without departing from the teachings of this document.

[0043] It will be understood that when an element is referred to as "connected" or "coupled" to another element, it can be directly connected or coupled to that other element, or there may be one or more intermediate elements. Conversely, when an element is referred to as "directly connected" or "directly coupled" to another element, there are no intermediate elements. Other terms used to describe the relationship between elements should be interpreted in a similar manner (e.g., "between" and "directly between," "adjacent" and "directly adjacent," etc.).

[0044] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, “a,” “an,” “the,” and “at least one” do not indicate a limitation of quantity and are intended to include both the singular and the plural unless the context clearly indicates otherwise. Thus, reference to “a” followed by “the” in the claims includes one element and multiple elements. For example, “element” has the same meaning as “at least one element” unless the context clearly indicates otherwise. “At least one” should not be construed as limiting “a” or “an.” “Or” means “and / or.” As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. It will be further understood that the terms “comprising” and / or “including” or “containing” and / or “including” as used in this specification specify the presence of the stated features, areas, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, areas, integrals, steps, operations, elements, components, and / or groups thereof.

[0045] Furthermore, relative terms such as “down” or “bottom” and “up” or “top” may be used herein to describe the relationship between one element and another as illustrated in the figures. It will be understood that relative terms are intended to cover different orientations of the device beyond those depicted in the figures. For example, if the device in one of the figures is flipped, an element described as being “down” to other elements would be positioned “up” to other elements. Thus, depending on the specific orientation of the figure, the term “down” can encompass both “down” and “up” orientations. Similarly, if the device in one of the figures is flipped, an element described as being “below” or “under” other elements would be positioned “above” other elements. Thus, the terms “below” or “under” can encompass both “up” and “below” orientations.

[0046] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which the inventive concept pertains. It will be further understood that terms such as those defined in common dictionaries shall be interpreted as having the meaning consistent with their meaning in the context of the relevant field, and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0047] In this specification, the x-axis, y-axis, and z-axis are not limited to three axes in an orthogonal coordinate system, but can be interpreted in a broad sense that includes these three axes. For example, the x-axis, y-axis, and z-axis can be perpendicular to each other, or they can represent different directions that are not perpendicular to each other. Here, the x-axis direction can be referred to as the x-direction or x-axis direction, the y-axis direction can be referred to as the y-direction or y-axis direction, and the z-axis direction can be referred to as the z-direction or z-axis direction.

[0048] This document describes embodiments with reference to schematic cross-sectional views illustrating idealized embodiments. Thus, variations from the illustrated shapes are expected due to factors such as manufacturing techniques and / or tolerances. Therefore, the embodiments described herein should not be construed as limited to the specific shapes of the regions illustrated herein, but should include shape deviations, for example, due to manufacturing processes. For instance, regions illustrated as or described as flat may generally have rough and / or non-linear characteristics. Furthermore, illustrated sharp corners may be rounded. Therefore, the regions illustrated are schematic in nature and their shapes are not intended to represent the precise shapes of the regions, nor are they intended to limit the scope of these claims.

[0049] The embodiments will be described in detail below with reference to the accompanying drawings.

[0050] Figure 1 This is a schematic diagram illustrating a distribution device according to an embodiment. Figure 2 It is shown in the figure. Figure 1 A plan view of the resin control electrode.

[0051] refer to Figure 1 and Figure 2 In an embodiment, the dispensing device 100 may include a stage 110, a dispensing head 120, a resin supply unit 130, a resin control electrode 140, a head moving unit 161, an electrode moving unit 162, a power supply unit 170, a measurement unit 180, and a control unit (or controller) 190.

[0052] The substrate S can be placed on the stage 110. The substrate S can be placed on the upper surface of the stage 110. In an embodiment, for example, the upper surface of the stage 110 may be substantially parallel to the xy plane. In an embodiment, for example, the substrate S may be a display module or a substrate in an intermediate stage of manufacturing a display module, but the invention is not limited thereto.

[0053] The dispensing head 120 can be positioned from the stage 110 and the substrate S in the upward direction (+z direction). The dispensing head 120 can dispense (or dispense) coating material toward the substrate S in the downward direction (-z direction), which is the direction of gravity. In an embodiment, the dispensing device 100 can be a resin dispensing device for dispensing (or dispensing) resin R. The dispensing head 120 can dispense resin R in a point form through the nozzle 121c. That is, the resin R supplied from the resin supply unit 130 can be continuously or successively dispensed toward the substrate S in a fine point form by the dispensing head 120. Hereinafter, the resin R dispensed in a point form from the nozzle 121c of the dispensing head 120 can be referred to as resin point RD.

[0054] In an embodiment, the dispensing head 120 may include a plate 121, a head electrode 122, a rod 123, and a rod driving unit 124.

[0055] Plate 121 can form the body of dispensing head 120. Plate 121 can define inflow channel 121a, outflow channel 121b, nozzle 121c, and receiving space 121d. In embodiments, plate 121 can be provided by combining multiple plates (e.g., nozzle plate, channel plate, etc.).

[0056] The inflow channel 121a can be connected to the resin supply unit 130. The resin R, which is the coating material, can be stored in the storage space of the resin supply unit 130. The storage space of the resin supply unit 130 can be connected to the inflow channel 121a of the dispensing head 120 via a pipe 131. Therefore, the resin R stored in the resin supply unit 130 can be introduced into the inflow channel 121a of the dispensing head 120 via the pipe 131.

[0057] The head electrode 122 may be adjacent to (e.g., close to) the inflow channel 121a. The head electrode 122 may include a conductive material, such as a metal or alloy. In embodiments, for example, the head electrode 122 may include a highly conductive metal, such as copper, but this is merely an example and the invention is not limited thereto.

[0058] A first voltage may be applied to the head electrode 122 to charge the resin R flowing through the inflow channel 121a. In an embodiment, for example, the first voltage may be a positive voltage. The resin R flowing through the inflow channel 121a can be positively charged through the head electrode 122. In an embodiment, for example, the amplitude (or voltage level) of the first voltage may be in the range of about 0.1 kV to about 10 kV, but this is merely an example and the invention is not limited thereto.

[0059] In an embodiment, such as Figure 1 As illustrated, the head electrode 122 can be configured to directly contact the resin R in the inflow channel 121a to charge the resin R. In an embodiment, for example, the head electrode 122 can be formed to at least partially surround the inflow channel 121a, but this is merely an example and the invention is not limited thereto. In an embodiment, the head electrode 122 can be configured to further contact the lower portion of the outflow channel 121b and the nozzle 121c.

[0060] The outflow channel 121b can extend from the nozzle 121c in an upward direction (+z direction) and can communicate with the inflow channel 121a and the receiving space 121d. In an embodiment, for example, the inflow channel 121a can communicate with the middle portion of the outflow channel 121b and can extend from the middle portion of the outflow channel 121b in one direction (e.g., the +x direction).

[0061] Nozzle 121c may be provided or defined at the lower portion of the outflow channel 121b. In embodiments, for example, nozzle 121c may be formed to be relatively small (e.g., to have a relatively small cross-sectional area) to discharge minute amounts of resin R and improve discharge accuracy. The diameter of nozzle 121c may be smaller than the diameter of outflow channel 121b. In embodiments, for example, the diameter of nozzle 121c may be in the range of about 10 micrometers to 100 micrometers, but this is merely an example, and the invention is not limited thereto.

[0062] A portion of the lower part of the outflow channel 121b (between the middle part of the outflow channel 121b that communicates with the inflow channel 121a and the nozzle 121c) can be filled with resin R, which is introduced through the inflow channel 121a and positively charged through the head electrode 122.

[0063] The receiving space 121d can communicate with the upper part of the outflow channel 121b. The rod 123 and the rod drive unit 124 can be disposed in the receiving space 121d.

[0064] Rod 123 can extend in the z-axis direction. The lower portion of rod 123 can be inserted into the outflow channel 121b. The upper portion of rod 123 can be connected to rod drive unit 124. Rod 123 can be driven in the upward and downward directions (+z and -z directions) by rod drive unit 124. When rod 123 is driven in the upward and downward directions (+z and -z directions), the positively charged resin R contained in the lower portion of the outflow channel 121b can be discharged in a point form from nozzle 121c to the outside of dispensing head 120. That is, the resin point RD discharged from nozzle 121c of dispensing head 120 can be positively charged.

[0065] A rod drive unit 124 can be connected to the upper portion of the rod 123 in the receiving space 121d. The rod drive unit 124 can drive the rod 123 in both upward and downward directions (+z and -z directions). In embodiments, the rod drive unit 124 can be a piezoelectric element that contracts or expands depending on the voltage applied to it, but the invention is not limited thereto, and the rod drive unit 124 can be modified in various ways (e.g., a cylinder, etc.).

[0066] The resin control electrode 140 can be located between the dispensing head 120 and the stage 110. The resin control electrode 140 can be positioned from the stage 110 in the upward direction (+z direction) and from the dispensing head 120 in the downward direction (-z direction). The resin control electrode 140 can control the path of the resin dot RD by adjusting the position of the resin dot RD discharged from the nozzle 121c of the dispensing head 120.

[0067] The resin control electrode 140 may comprise a conductive material, such as a metal or alloy. In an embodiment, for example, the resin control electrode 140 may comprise a highly conductive metal, such as copper, but this is merely an example, and the invention is not limited thereto. A second voltage having the same polarity as the first voltage may be applied to the resin control electrode 140 to control the position of the resin point RD discharged from the nozzle 121c. In an embodiment, for example, the second voltage may be a positive voltage. In an embodiment, for example, the amplitude of the second voltage may be in the range of about 0.1 kV to about 10 kV, but this is merely an example, and the invention is not limited thereto.

[0068] In an embodiment, in a plan view, the resin control electrode 140 may have an annular shape in which the opening OP is defined at its inner portion. In an embodiment, for example, as... Figure 2 As illustrated, the resin control electrode 140 may have an annular shape in a plan view, but this is merely an example, and the invention is not limited thereto. In embodiments, for example, the radius D of the opening OP of the resin control electrode 140 may be in the range of about 1 mm to about 10 mm, the width W of the resin control electrode 140 may be in the range of about 0.1 mm to about 1 mm, and the thickness T of the resin control electrode 140 may be in the range of about 0.1 mm to about 1 mm, but this is merely an example, and the invention is not limited thereto.

[0069] The resin control electrode 140 can be located below the dispensing head 120, such that the nozzle 121c of the dispensing head 120 is positioned within (or overlaps with) the opening OP of the resin control electrode 140 in a plan view (or in the z-direction). That is, the resin dots RD discharged from the nozzle 121c of the dispensing head 120 can pass through the opening OP of the resin control electrode 140 and land on the substrate S. At this time, since the resin control electrode 140 is charged with the same polarity as the resin dots RD, the resin dots RD can move towards the center point 140c of the resin control electrode 140 due to the repulsive force RF between the resin dots RD and the resin control electrode 140 (see [link to relevant documentation]). Figure 2 ).

[0070] As described below, the resin control electrode 140 can be moved relative to the dispensing head 120 via the electrode moving unit 162. According to an embodiment, the dispensing device 100 can control the path of the resin dot RD by appropriately adjusting the position of the resin control electrode 140 relative to the dispensing head 120 in real time based on the landing state of the resin dot RD, so that the resin dot RD can land at a target position on the substrate S. In such an embodiment, the smaller the resin dot RD, the greater the influence of the resin control electrode 140 on controlling the path of the resin dot RD.

[0071] The head moving unit 161 can be connected to the dispensing head 120 and can be configured to move the dispensing head 120 relative to the stage 110. In an embodiment, while the stage 110 is fixed, the dispensing head 120 can be moved by the head moving unit 161 and resin dots RD are dispensed at target locations on the substrate S, thereby forming resin layers RSL of various shapes. The head moving unit 161 can move the dispensing head 120 relative to the stage 110 in the x-axis, y-axis, and / or z-axis directions. In an embodiment, the head moving unit 161 can refer to a mechanical part or assembly that enables the dispensing head 120 to move in various directions or positions, and may include, for example, a motor, cylinder, or electric actuator.

[0072] Electrode moving unit 162 can be connected to resin control electrode 140 and can be configured to move resin control electrode 140. Electrode moving unit 162 can move resin control electrode 140 in the x-axis direction, y-axis direction, and / or z-axis direction. In embodiments, electrode moving unit 162 can refer to a mechanical part or assembly that enables resin control electrode 140 to move in various directions or positions, and may include, for example, a motor, cylinder, or electric actuator.

[0073] In this embodiment, the resin control electrode 140 can move together with the dispensing head 120 as the dispensing head 120 moves. That is, the resin control electrode 140 can move relative to the stage 110 together with the dispensing head 120 via the head moving unit 161, and can also move relative to the dispensing head 120 simultaneously via the electrode moving unit 162.

[0074] In this embodiment, the dispensing head 120 and the resin control electrode 140 can be moved independently of each other via the head moving unit 161 and the electrode moving unit 162. In this embodiment, the electrode moving unit 162 can move the resin control electrode 140 such that when the dispensing head 120 moves, the resin control electrode 140 moves together with the dispensing head 120. Furthermore, when it is desired to correct the landing position of the resin point RD, the electrode moving unit 162 can move the resin control electrode 140 such that the resin control electrode 140 also moves relative to the dispensing head 120.

[0075] The power supply unit 170 can apply voltage to components of the dispensing device 100. The power supply unit 170 may include a first power supply unit 171 that applies a first voltage to the head electrode 122 and a second power supply unit 172 that applies a second voltage to the resin control electrode 140. The first power supply unit 171 and the second power supply unit 172 can independently apply the first voltage to the head electrode 122 and the resin control electrode 140, respectively. The first power supply unit 171 and the second power supply unit 172 can be configured as multiple channels of a single power supply device, or they can be configured as multiple power supply devices.

[0076] The measurement unit 180 can generate measurement data by measuring the landing position of the resin dots RD on the substrate S. In an embodiment, for example, the measurement unit 180 may include a camera. In an embodiment, when the dispensing head 120 dispenses the resin dots RD, the measurement unit 180 can acquire an image of the substrate S in real time and generate measurement data in real time. In an embodiment, after the resin dots RD landing on the substrate S are cured, the measurement unit 180 can acquire an image of the substrate S and generate measurement data.

[0077] The control unit 190 can control the operation of each component of the dispensing device 100. In an embodiment, the control unit 190 may be included in a processor.

[0078] In this embodiment, the control unit 190 can receive measurement data from the measurement unit 180. In this embodiment, the control unit 190 can receive measurement data generated in real time by the measurement unit 180.

[0079] The control unit 190 can control the head moving unit 161 to move the dispensing head 120 relative to the stage 110.

[0080] The control unit 190 can control the electrode moving unit 162 to move the resin control electrode 140 relative to the dispensing head 120 based on the measurement data received from the measuring unit 180.

[0081] The control unit 190 can receive measurement data from the measurement unit 180 in real time and can check the landing status of the resin dots RD on the substrate S in real time based on the measurement data. In an embodiment, for example, the control unit 190 can check the landing status of the resin dots RD by calculating the error between the landing position and the target position based on the measurement data. Based on the check result of the landing status of the resin dots RD, the control unit 190 can control the head moving unit 161 to adjust the position of the dispensing head 120 relative to the stage 110, or it can control the electrode moving unit 162 to adjust the position of the resin control electrode 140 relative to the dispensing head 120. (See below for further details.) Figure 5 This will be described in detail.

[0082] In one embodiment, the control unit 190 may control the power supply unit 170 to adjust the amplitude of the first voltage and / or the amplitude of the second voltage based on the inspection results of the landing status of the resin point RD.

[0083] According to the dispensing apparatus 100 of the embodiment, charged resin R can be discharged from the nozzle 121c of the dispensing head 120 in the form of dots. The discharged resin dots RD can pass through the opening OP of the resin control electrode 140 (which is charged with the same polarity as the charged resin R (i.e., resin dots RD)) and can land on the substrate S. The control unit 190 can check the landing status of the resin dots RD on the substrate S in real time and can control the path of the resin dots RD discharged from the nozzle 121c in real time based on the check results. In the embodiment, for example, the control unit 190 can control the path of the resin dots RD in real time by adjusting the position of the resin control electrode 140 relative to the dispensing head 120 in real time based on the check results, so that the resin dots RD can land at the target position on the substrate S. Therefore, even when the resin dots RD are discharged from the nozzle 121c in an inclined direction due to nozzle blockage, increased moving speed of the dispensing head 120, etc., the dispensing apparatus 100 can control the path of the resin dots RD in real time, so that the resin dots RD can land at the target position on the substrate S. Therefore, the emission accuracy of the distribution equipment 100 can be improved.

[0087] The dispensing head 120 can charge the resin R supplied from the resin supply unit 130, and can discharge the charged resin R in a point form through the nozzle 121c.

The third resin control electrode 143 can be positioned from the stage 110 in the upward direction (+z direction) and from the second resin control electrode 142 in the downward direction (-z direction).

[0089] The first to third resin control electrodes 141, 142 and 143 can control the path of the resin point RD by adjusting the position of the resin point RD discharged from the nozzle 121c of the dispensing head 120. Figure 3 The figure shows an embodiment of the dispensing device 101 including three resin control electrodes, but the number of resin control electrodes can be varied, for example, two or four or more.

[0090] Each of the first to third resin control electrodes 141, 142, and 143 may include a conductive material, such as a metal or alloy. In an embodiment, for example, each of the first to third resin control electrodes 141, 142, and 143 may include a highly conductive metal, such as copper, but this is merely an example, and the invention is not limited thereto.

[0091] A second voltage with the same polarity as the first voltage applied to the head electrode 122 can be applied to the first resin control electrode 141. A third voltage with the same polarity as the first voltage can be applied to the second resin control electrode 142. A fourth voltage with the same polarity as the first voltage can be applied to the third resin control electrode 143.

In a plan view, the second resin control electrode 142 may have an annular shape in which a second opening OP2 is defined in its inner portion. In a plan view, the third resin control electrode 143 may have an annular shape in which a third opening OP3 is defined in its inner portion. In an embodiment, for example, the first to third resin control electrodes 141, 142, and 143 may have substantially the same width and substantially the same thickness, but the invention is not limited thereto.

[0094] In one embodiment, in a plan view, the dimensions of the first to third openings OP1, OP2, and OP3 may be different from each other. In another embodiment, for example, in a plan view, the size of the second opening OP2 may be smaller than the size of the first opening OP1, and the size of the third opening OP3 may be smaller than the size of the second opening OP2. In yet another embodiment, in a plan view, the dimensions of the first to third openings OP1, OP2, and OP3 may be equal to each other.

[0095] Resin dots RD discharged from nozzle 121c of dispensing head 120 can sequentially pass through the first opening OP1 of the first resin control electrode 141, the second opening OP2 of the second resin control electrode 142, and the third opening OP3 of the third resin control electrode 143, and can land on the substrate S. At this time, since each of the first to third resin control electrodes 141, 142, and 143 is charged with the same polarity as the resin dots RD, the resin dots RD can move towards the center point of each of the first to third resin control electrodes 141, 142, and 143 by the repulsive force between the resin dots RD and each of the first to third resin control electrodes 141, 142, and 143.

[0096] The head moving unit 161 can be connected to the dispensing head 120 and can be configured to move the dispensing head 120 relative to the stage 110. In an embodiment, while the stage 110 is fixed, the dispensing head 120 can be moved by the head moving unit 161 and resin dots RD are dispensed at target positions on the substrate S to form resin layers RSL of various shapes.

[0099] The third electrode moving unit 164 can be connected to the third resin control electrode 143 and can be configured to move the third resin control electrode 143. The third electrode moving unit 164 can move the third resin control electrode 143 in the x-axis direction, y-axis direction and / or z-axis direction.

[0100] In an embodiment, the first to third electrode moving units 162, 163 and 164 can be configured to independently move the first to third resin control electrodes 141, 142 and 143, respectively.

[0101] In this embodiment, when the dispensing head 120 moves, the first to third resin control electrodes 141, 142, and 143 can move together with the dispensing head 120. That is, the first to third resin control electrodes 141, 142, and 143 can move relative to the stage 110 with the dispensing head 120 via the head moving unit 161, and can also move relative to the dispensing head 120 simultaneously via the first to third electrode moving units 162, 163, and 164.

In this embodiment, the first to third electrode moving units 162, 163, and 164 can move the first to third resin control electrodes 141, 142, and 143 such that when the dispensing head 120 moves, the first to third resin control electrodes 141, 142, and 143 move together with the dispensing head 120. Furthermore, when it is desired to correct the landing position of the resin point RD, the first to third electrode moving units 162, 163, and 164 can move the first to third resin control electrodes 141, 142, and 143 such that the first to third resin control electrodes 141, 142, and 143 also move relative to the dispensing head 120.

The first to fourth power supply units 171, 172, 173, and 174 can be configured as multiple channels of a single power supply device, or can be configured as multiple power supply devices.

[0104] The measurement unit 180 can generate measurement data by measuring the landing position of the resin dots RD on the substrate S.

[0105] The control unit 190 can control the operation of each component of the dispensing device 101. In this embodiment, the control unit 190 can receive measurement data generated in real time by the measurement unit 180.

[0106] The control unit 190 can receive measurement data from the measurement unit 180 in real time and can check the landing status of the resin dots RD on the substrate S in real time based on the measurement data. In an embodiment, for example, the control unit 190 can check the landing status of the resin dots RD by calculating the error between the landing position and the target position based on the measurement data. Based on the check result of the landing status of the resin dots RD, the control unit 190 can control the head moving unit 161 to adjust the position of the dispensing head 120 relative to the stage 110, or it can control the first to third electrode moving units 162, 163 and 164 to adjust the position of the first to third resin control electrodes 141, 142 and 143 relative to the dispensing head 120.

[0107] According to an embodiment, as described above, the dispensing device 101 may include a plurality of resin control electrodes 141, 142, and 143 arranged along the discharge path of the resin point RD discharged from the nozzle 121c of the dispensing head 120.

[0109] The following is for reference Figure 4 The embodiments of the distribution device 102 described above can be referenced. Figure 1The embodiments of the distribution device 100 described are substantially the same or similar, except that some details are omitted. Figure 1 The head moving unit 161 further includes a stage moving unit 165. Therefore, any repeated detailed descriptions of elements that are the same as or similar to those described above will be omitted or simplified.

[0110] In an embodiment, the dispensing head 120 can charge the resin R supplied from the resin supply unit 130, and the charged resin R can be discharged in a point form through the nozzle 121c.

[0111] The resin control electrode 140 can be located between the dispensing head 120 and the stage 110. The resin control electrode 140 can control the path of the resin dot RD by adjusting the position of the resin dot RD discharged from the nozzle 121c of the dispensing head 120.

The electrode moving unit 162 can move the resin control electrode 140 in the x-axis direction, y-axis direction and / or z-axis direction.

[0113] A stage moving unit 165 can be connected to the stage 110 and configured to move the stage 110 relative to the dispensing head 120.

In an embodiment, the stage moving unit 165 can refer to a mechanical part or assembly that enables the stage 110 to move in various directions or positions, and may include, for example, a motor, cylinder, or electric actuator.

[0114] Figure 5 This is a flowchart illustrating an allocation method according to an embodiment.

[0115] Figure 5 The allocation method can be based on the above references. Figures 1 to 4 The distribution method performed by embodiments of the distribution devices 100, 101, or 102 described herein. Further reference will be made below for ease of description. Figure 1 Describes the allocation method according to an embodiment.

[0116] In an embodiment of the dispensing method, the dispensing head 120 can dispense resin R onto the substrate S in a point-like manner through the nozzle 121c (step S110). Resin R supplied from the resin supply unit 130 can be continuously dispensed toward the substrate S in a fine point-like manner through the dispensing head 120.

[0117] Before dispensing resin R onto the substrate S (step S110), the resin R can be charged inside the dispensing head 120. A first voltage can be applied to the head electrode 122 adjacent to the inflow channel 121a of the dispensing head 120 to charge the resin R passing through the inflow channel 121a. In an embodiment, for example, the first voltage can be a positive voltage. The resin R passing through the inflow channel 121a can be positively charged through the head electrode 122. Therefore, the positively charged resin R can be discharged to the outside of the dispensing head 120 in the form of a point through the nozzle 121c of the dispensing head 120. That is, the resin point RD discharged from the nozzle 121c of the dispensing head 120 can be positively charged.

[0118] The control unit 190 can check the landing status of the resin R (i.e., the resin dot RD) on the substrate S (step S120).

[0119] In this embodiment, before checking the landing state of the resin R (step S120), measurement data can be generated by measuring the landing position of the resin R (i.e., the resin dot RD) on the substrate S. The measurement unit 180 can generate measurement data by measuring the landing position of the resin dot RD on the substrate S. When the dispensing head 120 dispenses the resin dot RD, the measurement unit 180 can acquire an image of the substrate S in real time and generate measurement data in real time.

[0120] The control unit 190 can receive measurement data generated in real time by the measurement unit 180. Based on the measurement data received from the measurement unit 180, the control unit 190 can check the landing status of the resin dot RD on the substrate S in real time (step S120). The control unit 190 can check the landing status of the resin dot RD by calculating the error between the landing position and the target position of the resin dot RD based on the measurement data.

[0121] The control unit 190 can control the landing position of the resin R (i.e., the resin dot RD) based on the landing status inspection results (step S130). Based on the landing status inspection results, the control unit 190 can control the head moving unit 161 to adjust the position of the dispensing head 120 relative to the stage 110, or it can control the electrode moving unit 162 to adjust the position of the resin control electrode 140 relative to the dispensing head 120, so that the landing position of the resin R (i.e., the resin dot RD) on the substrate S can be controlled.

[0122] In this embodiment, the control unit 190 can determine whether the error is less than or equal to a first threshold (step S131). If the error is less than or equal to the first threshold (step S131: Yes), the control unit 190 can determine that the landing state of the resin R is normal. If the error is greater than the first threshold (step S131: No), the control unit 190 can determine whether the error is less than or equal to a second threshold greater than the first threshold (step S132).

[0123] In this embodiment, if the error is greater than a first threshold and less than or equal to a second threshold (step S132: Yes), the electrode moving unit 162 can move the resin control electrode 140 to adjust the position of the resin control electrode 140 relative to the dispensing head 120 (step S133). If the error is greater than the first threshold and less than or equal to the second threshold (step S132: Yes), the control unit 190 can control the electrode moving unit 162 to move the resin control electrode 140 relative to the dispensing head 120 (step S133).

[0124] In one embodiment, if the error is greater than the second threshold (step S132: No), the head moving unit 161 can move the dispensing head 120 to adjust the position of the dispensing head 120 relative to the stage 110 (step S134). In another embodiment, the stage moving unit 165 can move the stage 110 to adjust the position of the dispensing head 120 relative to the stage 110. If the error is greater than the second threshold (step S132: No), the control unit 190 can control the head moving unit 161 to move the dispensing head 120 relative to the stage 110 (step S134). At this time, when the dispensing head 120 moves, the resin control electrode 140 can move together with the dispensing head 120.

[0125] In an embodiment, for example, the first threshold may be 20 micrometers and the second threshold may be 50 micrometers, but this is merely an example and the invention is not limited thereto.
