[0003] This disclosure relates to deposition equipment, deposition methods for display devices, and electronic devices including display devices. Background Technology
[0004] Organic light-emitting display devices utilize the recombination of electrons injected from the cathode and holes injected from the anode in an organic thin film to form excitons, and when the excitons relax from the excited state to the ground state, they generate light of a specific wavelength as energy is released.
[0005] In organic light-emitting display devices, vacuum deposition using a deposition apparatus can be used as a method for depositing organic materials or metals used as electrodes. Vacuum deposition can be performed by placing a substrate on which an organic thin film is to be grown inside a vacuum chamber, bringing a deposition mask with the same pattern as the pattern of the thin film to be formed into contact with the substrate, and then using a deposition source to evaporate or sublimate a deposition material such as an organic material to deposit the deposition material on the substrate.

Detailed Implementation
[0032] 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 herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. The same reference numerals throughout denote the same elements.
[0033] It will be understood that when an element is referred to as being "on" another element, it can be directly on the other element, or there can be an intervening element between them. Conversely, when an element is referred to as being "directly" on another element, there is no intervening element.
[0034] 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, and / or part from another element, component, region, layer, and / or part. Therefore, without departing from the teachings herein, “first element,” “first component,” “first region,” “first layer,” or “first part” discussed below may be referred to as a second element, second component, second region, second layer, or second part.
[0035] 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” element in a claim followed by “the” element 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 also be understood that when the terms “comprising” and / or “including” or “containing” and / or “containing” are used in this specification, they 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, and / or groups thereof.
[0036] Furthermore, relative terms such as “below” or “bottom” and “above” or “top” may be used herein to describe the relationship between one element and another, as shown in the accompanying drawings. It will be understood that, in addition to the orientations depicted in the drawings, the relative terms are intended to also encompass different orientations of the device. For example, if a device in one of the drawings is flipped, an element described as being “below” the other elements will subsequently be oriented “above” the other elements. Thus, the term “below” can encompass both “below” and “above” orientations, depending on the specific orientation of the drawing. Similarly, if a device in one of the drawings is flipped, an element described as being “below” or “under” the other elements will subsequently be oriented “above” the other elements. Thus, the term “below” or “under” can encompass both “above” and “below” orientations.
[0037] Unless otherwise specified, 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 this disclosure pertains. It will also be understood that terms such as those defined in common dictionaries shall be interpreted as having meanings consistent with their meanings in the relevant technical context and in the context of this disclosure, and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.
[0038] Embodiments are described herein with reference to cross-sectional views, which are schematic diagrams of idealized embodiments. Therefore, deviations from the illustrated shapes will be anticipated, for example, due to manufacturing techniques and / or tolerances. Consequently, the embodiments described herein should not be construed as limited to the specific shapes of the regions shown herein, but should include, for example, deviations in shape due to manufacturing processes. For instance, regions shown or described as flat may generally have rough and / or non-linear characteristics. Furthermore, sharp corners shown may be rounded. Therefore, the regions shown in the figures are schematic in nature, and their shapes are not intended to illustrate the precise shapes of the regions, nor are they intended to limit the scope of the claims.
[0039] Features of the various exemplary embodiments of this disclosure can be combined in part or in whole. As will be clearly understood by those skilled in the art, various technical interactions and operations are possible. The various exemplary embodiments can be practiced individually or in combination.
[0040] In the following, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
[0041] Figure 1 This is a side view showing a deposition apparatus according to an embodiment of the present disclosure. Figure 2 yes Figure 1 Front view of the deposition equipment.
[0042] refer to Figure 1 and Figure 2 The deposition apparatus 100 according to embodiments of the present disclosure may include a chamber 110, a deposition source 120, a track 130, and a moving module 140.
[0043] Chamber 110 provides space for performing deposition processes. During the deposition process, the interior of chamber 110 can be maintained under vacuum. Being under vacuum means maintaining a low pressure inside chamber 110. Chamber 110 may include an inlet / outlet (not shown) for loading / unloading the substrate SUB. Furthermore, chamber 110 may include a vacuum pump (not shown) for controlling the pressure inside chamber 110 and discharging any deposited material not deposited on the substrate SUB, and an exhaust port (not shown) connected to the vacuum pump.
[0044] The substrate SUB on which organic materials or metals used as electrodes are deposited can be configured as an insulating substrate, a semiconductor substrate, a display device substrate, etc., but this disclosure is not limited thereto. According to embodiments, a substrate SUB used in an organic light-emitting display device is described as an example. A predetermined structure can be formed on the substrate SUB via a deposition process. Depending on the manufacturing process of the organic light-emitting display device, structures formed on the substrate SUB via deposition processes can be formed in various ways. In embodiments, for example, in the process of forming a hole injection layer, a pixel defining layer and an anode electrode can be formed on the substrate SUB. Furthermore, in the process of forming an organic light-emitting layer, not only can a pixel defining layer and an anode electrode be formed on the substrate SUB, but also a hole injection layer and a hole transport layer can be formed on the substrate SUB.
[0045] The deposition source 120 can provide the deposition material to be deposited on the substrate SUB. The deposition source 120 can be disposed on the lower side of the chamber 110. The deposition source 120 may include a deposition source body 121 and a plurality of deposition nozzles 122.
[0046] The deposition source body 121 can support a plurality of deposition nozzles 122. The deposition source body 121 can be configured as a block with a predetermined thickness and can extend at the bottom in a first direction D1 within the chamber 110 (or on the inner bottom surface of the chamber 110). A space for accommodating the deposition material can be provided or formed in the deposition source body 121.
[0047] The deposition nozzle 122 can provide deposition material to the substrate SUB by spraying deposition material. The deposition nozzle 122 can be disposed on the upper surface of the deposition source body 121 and supported by the deposition source body 121. The deposition nozzles 122 can be spaced apart from each other on the upper surface of the deposition source body 121 in a first direction D1.
[0048] Track 130 may be disposed above deposition source 120. Track 130 may be disposed above deposition source 120 along the direction in which deposition nozzle 122 is arranged. In some embodiments, track 130 may be disposed above deposition source 120 along a first direction D1. Track 130 may include a plurality of rollers. Rollers may be spaced apart from each other above deposition source 120 along the first direction D1. Track 130 may be disposed above deposition source 120 at two opposite sides of deposition source 120. In some embodiments, track 130 may be disposed on two opposite sides of deposition source 120 to form a space for flow of deposited material. Track 130 may be disposed below moving module 140, and moving module 140 may be moved in the first direction D1 by operation of track 130.
[0049] Figure 3 yes Figure 1 Side view of the mobile module. Figure 4 yes Figure 3 The front view of the moving module. Figure 5 yes Figure 3 A floor plan of the mobile module. Figure 6 It is shown Figure 3 A block diagram of the track, camera, laser irradiator, sound sensor, and controller.
[0050] refer to Figures 3 to 6 In one embodiment, the moving module 140 may be mounted on and movable along the track 130. In some embodiments, the moving module 140 may be moved in a first direction D1 by operation of the track 130. The moving module 140 may include a carrier 141, a deposition mask 142, a mask support 143, a camera 144, a laser irradiator 145, a sound sensor 146, and a controller 147.
[0051] The carrier 141 can hold the substrate SUB. When viewed from above (or in a plan view), the carrier 141 can be rectangular in shape and can have a predetermined thickness. An opening can be defined or formed by passing through the center of the carrier 141 or by penetrating the carrier 141 in the thickness direction (or third direction D3). The opening can overlap with the substrate SUB and the deposition mask 142. The substrate SUB can be disposed below the carrier 141 and held by the carrier 141.
[0052] A deposition mask 142 may be supported by a carrier 141 and may be disposed below a substrate SUB. The deposition mask 142 may be connected to the carrier 141 via a mask support 143. The deposition mask 142 may define an area of the substrate SUB where deposition material ejected from the deposition source 120 is deposited. The deposition mask 142 may include a mask portion and a transmission portion. The mask portion may cover an area of the substrate SUB to prevent deposition material ejected from the deposition source 120 from depositing in that area of the substrate SUB. The transmission portion exposes an area of the substrate SUB and may be an opening defined or formed in the mask portion. Deposition material may be deposited on the area of the substrate SUB exposed by the transmission portion.
[0053] Mask support 143 can extend downward from carrier 141 and can be connected to deposition mask 142. In some embodiments, mask support 143 can connect carrier 141 to deposition mask 142 such that deposition mask 142 is supported by carrier 141. Because mask support 143 extends downward from carrier 141, mask support 143 can support deposition mask 142 in a manner that spaced the deposition mask 142 from carrier 141.
[0054] A camera 144 can be positioned at the carrier 141 to capture images of the deposition nozzle 122. The camera 144 can also be positioned at an end of the carrier 141 in the direction of movement of the carrier 141. In an embodiment, for example, in... Figure 3 In this configuration, camera 144 can be positioned at the right end of carrier 141 in the first direction D1. When the moving module 140 moves, camera 144 can capture an image of the deposition nozzle 122 positioned in front of the moving module 140 in the direction of movement. Camera 144 can then transmit the captured image of the deposition nozzle 122 to controller 147.
[0055] A laser irradiator 145 can be mounted on the carrier 141 to radiate laser light toward the deposition nozzle 122. The laser irradiator 145 can be positioned at an end of the carrier 141 in the direction of movement of the carrier 141. In some embodiments, for example, the laser irradiator 145 can be positioned at the right end of the carrier 141 in a first direction D1. The laser irradiator 145 can be positioned behind the camera 144 in the direction of movement of the moving module 140. In some embodiments, the camera 144 can be positioned forward of the laser irradiator 145 in the direction of movement of the moving module 140.
[0056] A sound sensor 146 can be mounted on the carrier 141 to detect sound in the chamber 110. The sound sensor 146 can transmit the detected sound in the chamber 110 to the controller 147.
[0057] Controller 147 can analyze the images captured by camera 144 to control laser irradiator 145. In some embodiments, controller 147 can compare an image of the deposition nozzle 122 captured by camera 144 with a pre-acquired image of the deposition nozzle 122 (e.g., a reference image of the deposition nozzle 122), and can control laser irradiator 145 based on the comparison result (i.e., the result obtained by comparing the image of the deposition nozzle 122 captured by camera 144 with the pre-acquired image of the deposition nozzle 122). In embodiments, for example, when a foreign object or similar object is present in the image of the deposition nozzle 122 captured by camera 144 and the foreign object or similar object is not in the pre-acquired image of the deposition nozzle 122, controller 147 can determine that a foreign object is present at the deposition nozzle 122. When it is determined that a foreign object is present at the deposition nozzle 122, controller 147 can control laser irradiator 145 to irradiate laser light onto the foreign object. The foreign object accumulated at the deposition nozzle 122 can be removed by the laser light irradiated from laser irradiator 145.
[0058] In one implementation, the controller 147 can analyze the sound detected by the sound sensor 146 to control the operation of the track 130. In some implementations, the controller 147 can compare the sound detected by the sound sensor 146 in the chamber 110 with a pre-acquired sound in the chamber 110 (e.g., a reference sound), and can control the operation of the track 130 based on the comparison result. In one implementation, for example, when the sound detected by the sound sensor 146 inside the chamber 110 is different from the pre-acquired sound inside the chamber 110, the controller 147 can determine that an anomaly exists in the deposition apparatus 100. When the normal sound inside the chamber 110 (i.e., the sound pre-acquired inside the chamber 110 while the deposition apparatus 100 is operating normally) is different from the current sound detected by the sound sensor 146 inside the chamber 110, the controller 147 can determine that an anomaly has occurred in the deposition apparatus 100. When an anomaly is determined to exist in the deposition apparatus 100, the controller 147 can interrupt the operation of the track 130 to stop the movement of the movement module 140.
[0059] When the decibel level of the sound inside chamber 110 detected by sound sensor 146 differs from the pre-acquired decibel level of the sound inside chamber 110, controller 147 can determine that an anomaly exists in deposition apparatus 100 and interrupt operation of track 130.
[0060] In the following description, a deposition method for a display device according to an embodiment of the present disclosure will be described with reference to the accompanying drawings.
[0061] A deposition method for a display device according to embodiments of the present disclosure may include: loading a substrate SUB on a carrier 141, wherein a deposition material is to be deposited on the substrate SUB; moving a moving module 140 along a track 130 disposed above the deposition nozzle 122 in a direction in which the deposition nozzle 122 is arranged; capturing an image of the deposition nozzle 122 by a camera 144; and controlling a laser irradiator 145 by a controller 147 analyzing the image captured by the camera 144.
[0062] Figure 7 This is a view showing a moving module on which a substrate is disposed in a method for manufacturing a display device according to an embodiment of the present disclosure, moving along a track.
[0063] refer to Figure 7In embodiments of the deposition method for a display device, mounting the substrate SUB on the carrier 141 may include mounting the substrate SUB below the carrier 141. In some embodiments, the substrate SUB may be disposed on the carrier 141 between the carrier 141 and the deposition mask 142.
[0064] In an embodiment of the deposition method for a display device, a moving module 140, which moves along a track 130 in the direction in which the deposition nozzle 122 is arranged, may include a carrier 141 on which a substrate SUB is mounted, moving along the track 130 in a first direction D1 according to the operation of the track 130. In some embodiments, the carrier 141 may pass through the deposition nozzle 122 along the track 130. As the carrier 141 passes through the deposition nozzle 122, deposition material ejected from the deposition nozzle 122 may pass through the deposition mask 142 and may be deposited on the substrate SUB.
[0065] During the process of capturing images of the deposition nozzle 122 via camera 144, the camera 144, positioned at the end of the carrier 141 in the direction of movement of the carrier 141, can capture images of the deposition nozzle 122 positioned on the front side in the direction of movement of the moving module 140, while the moving module 140 is moving. The camera 144 can then transmit the captured images of the deposition nozzle 122 to the controller 147.
[0066] Figure 8 It is shown Figure 7 A view of a laser irradiator removing foreign matter from a deposition nozzle.
[0067] refer to Figure 8 Controlling the laser irradiator 145 by the controller 147 through analysis of images captured by the camera 144 may include: the controller 147 comparing an image of the deposition nozzle 122 captured by the camera 144 with a pre-acquired image of the deposition nozzle 122; and the controller 147 controlling the laser irradiator 145 to radiate laser light based on the comparison result. In an embodiment, for example, the controller 147 may compare an image of the deposition nozzle 122 captured by the camera 144 with a pre-acquired image of the deposition nozzle 122, and may control the laser irradiator 145 based on the comparison result. When it is determined that a foreign object FS or similar object is present in the image of the deposition nozzle 122 captured by the camera 144 and that the foreign object FS or similar object is not present in the pre-acquired image of the deposition nozzle 122, the controller 147 may determine that a foreign object FS is present at the deposition nozzle 122. When it is determined that a foreign object FS is present at the deposition nozzle 122, the controller 147 may control the laser irradiator 145 to radiate laser light onto the foreign object FS. Foreign matter FS accumulated at the deposition nozzle 122 can be removed by laser radiation from the laser irradiator 145.
[0068] The deposition method of the display device according to the embodiments of the present disclosure may further include: detecting sound inside the chamber 110 by a sound sensor 146; and controlling the operation of the track 130 by a controller 147 by analyzing the sound detected by the sound sensor 146.
[0069] Figure 9 It is shown in Figure 7 A view of the laser irradiator moving along a track after removing foreign matter from the deposition nozzle.
[0070] refer to Figure 9 Foreign matter FS accumulated at the deposition nozzle 122 is removed by laser irradiator 145 (see Figure 8 Afterward, the moving module 140 can move along the track 130, and deposition material can be deposited on the substrate SUB. Detecting sound inside the chamber 110 via the sound sensor 146 can include detecting sound inside the chamber 110 via the sound sensor 146 during the process of continuously depositing deposition material on the substrate SUB. The sound sensor 146 can send the detected sound in the chamber 110 to the controller 147.
[0071] Controlling the operation of the track 130 by the controller 147 through analysis of the sound detected by the sound sensor 146 may include: the controller 147 comparing the sound inside the chamber 110 detected by the sound sensor 146 with a pre-acquired sound inside the chamber 110; and the controller 147 interrupting the operation of the track 130 based on the comparison result.
