[0027] ​​​It will be understood that when an element or layer is referred to as being “on” another element or layer, “connected to” or “coupled to” another element or layer, it can be directly on, connected or coupled to the other element or layer, or one or more intervening elements or layers can also be present. In contrast, when an element or layer is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another element or layer, there are no intervening elements or layers present. By way of example, when a first element is described as “coupled” or “connected” to a second element, it can be directly coupled or connected to the second element or it can be indirectly coupled or connected to the second element via one or more intervening elements.

[0028] In the figures, the size of various elements, layers, etc., can be exaggerated for clarity. Like reference numbers signify like elements in all figures. As used in herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. In addition, use of “may” in the description of a disclosed embodiment(s) relates to “one or more disclosed embodiments” of the disclosure. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list. For example, the expressions “at least one of a, b, and c” indicates only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c. As used herein, the term “use” can be considered synonymous with the term “utilize.” As used herein, the terms “substantially,” “about,” and similar terms are used as approximating terms and not as terms of degree, and are intended to account for the inherent variations in measurements or calculations that would be recognized by those of ordinary skill in the art.

[0029] It will be understood that, although the terms “first,” “second,” “third,” etc. can be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms are used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of example embodiments.

[0030] For purposes of the description hereinafter, spatial or directional terms, such as "below," "lower," "bottom," "above," "upper," and the like, can be used with reference to the illustrated embodiment. However, it will be understood that no absolute directions are intended by the use of these terms. Rather, these terms are used for convenience and are intended to be correlated with the directional illustrations in the respective views. In addition, terms such as "first" and / or "second" can be used herein to describe various components. Such terminology can be used as an arbitrary device convention for purposes of this description and thus, is not intended to convey any meaning beyond that of the intended use of such terms in the respective contexts.

[0031] The terminology used herein is for the purpose of describing embodiments of the present disclosure and is not intended to be limiting of the present disclosure. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0033] Further, any numerical ranges herein are intended to include all sub-ranges of the same whole number recited, as implicitly disclosed as being within the range. For example, a range from 1.0 to 10.0 should be read to include a range from a limit of 1.0 to a limit of 10.0, that is, all sub-ranges beginning with either 1.0 or 10.0 or in between are intended to be encompassed. Any maximum numerical limitation should be read as a minimum and any minimum numerical limitation should be read as a maximum. In this disclosure and

[0034] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0035] Hereinafter, embodiments of a substrate deposition apparatus and a substrate deposition method using the same according to the present disclosure will be described with reference to the accompanying drawings.

[0036] Figure 1 is a cross-sectional view of a substrate deposition apparatus SA according to an embodiment of the present disclosure, and Figure 2 is a cross-sectional view of a substrate deposition apparatus SA according to an embodiment of the present disclosure.

[0037] Hereinafter, D1 is referred to as a first direction, D2 crosses (e.g., intersects) the first direction D1 and is referred to as a second direction, and D3 crosses (e.g., intersects) each of the first direction D1 and the second direction D2 and is referred to as a third direction. The third direction D3 can be referred to as a vertical direction. In addition, each of the first direction D1 and the second direction D2 can be referred to as a horizontal direction.

[0038] Referring to Figure 1 and Figure 2 A substrate deposition apparatus SA can be provided. The substrate deposition apparatus SA can be a chamber in which a deposition process is performed on a substrate. For example, the substrate deposition apparatus SA can be an apparatus that heats a deposition source (e.g., a deposition material) and forms a deposition layer on a substrate to manufacture a display device. The substrate deposition apparatus SA can include a process chamber 1, a stage 3, and a deposition source module 5.

[0039] The process chamber 1 can include (or can form) a process space 1h. The process space 1h can be separated from an external space by the process chamber 1. A deposition process can be performed on a substrate in the process space 1h. The process space 1h can be maintained in a vacuum state during a deposition process for a substrate in the process space 1h. For this purpose, the process space 1h can be connected to a vacuum pump, however, the present disclosure should not be limited to this or be limited thereby.

[0040] The stage 3 can be placed (or disposed) in the process chamber 1. The stage 3 can support (e.g., can suspend) a substrate. When the substrate is disposed on the stage 3, a deposition process can be performed on the substrate. When the substrate is disposed on the stage 3, a hole (e.g., an opening) can be formed through the center of the stage 3 to expose a lower surface of the substrate downward. Two stages 3 can be provided in one process space 1h. For example, referring to Figure 1A first station 31 and a second station 33 can be provided. The first station 31 and the second station 33 can be arranged spaced apart from each other in the first direction D1. When a substrate is arranged on each of the first station 31 and the second station 33, a deposition process can be performed. When two substrates are placed in one process chamber 1, a deposition process can be performed on both substrates simultaneously or jointly. However, for the sake of illustration, embodiments will be described below in which the station 3 is single.

[0041] The deposition source module 5 can be placed in the process space 1h. For example, the deposition source module 5 can be arranged underneath the station 3. The deposition source module 5 can be movable in one or two horizontal directions. As an example, the deposition source module 5 can be movable in the second direction D2. Accordingly, the deposition source module 5 can be connected to a deposition source drive arrangement (e.g., a deposition source driver). A deposition process can be performed on a substrate while the deposition source module 5 is moving. A deposition material evaporated from the deposition source module 5 can be deposited on the substrate to form a deposition layer. This will be described in more detail later. One deposition source module 5 can be provided in one process chamber 1. For example, for a deposition process in which a deposition material is evaporated from a plurality of deposition sources, one deposition source module 5 can be provided in one process chamber 1. For example, for a deposition process in which a deposition material is evaporated from a plurality of deposition sources, one deposition source module 5 can be provided in one process chamber 1. Figure 1 For the embodiments shown in FIG. 1, a deposition process can be performed on substrates arranged on the two stations 31 and 33, respectively, by using one deposition source module 5. For this purpose, the deposition source module 5 can be movable in the first direction D1. However, the present disclosure should not be limited thereto or thereby. According to an embodiment, two deposition source modules can be provided. The deposition source module 5 will be described in more detail later.

The first deposition material 519 stored in the first storage space can be discharged to the outside of the first deposition case 511 through the first nozzle 513. The first deposition material 519 can be filled in the first deposition case 511. When the first deposition material 519 in the first deposition case 511 is heated, at least a portion of the first deposition material 519 can be evaporated. The evaporated first deposition material 519 can be discharged to the outside through the first nozzle 513.

The second blocking plate 5251 can have a second blocking hole (e.g., a second blocking opening) 5251h. The second blocking hole 5251h can be through (e.g., can extend through) the second blocking plate 5251 from the top to the bottom. When viewed in a planar surface, the second blocking hole 5251h can have a rectangular shape; however, the present disclosure is not to be limited thereto or thereby. The second blocking hole 5251h can have a second width (or a second diameter) w2. The second width w2 can be different from the first width w1.

When the first deposition sources 51 are provided as a plurality, the first nozzles 513 can also be provided as a plurality. The first nozzles 513 can be arranged along the first direction D1. Among the first deposition sources 51, a first distance DS1 (i.e., a separation distance in the first direction D1 between two first deposition sources 51 adjacent to an edge (or end) of the first blocker plate 5151) can be different from a second distance DS2 (i.e., a separation distance in the first direction D1 between two first deposition sources 51 at (or near) a center of the first blocker plate 5151). The first distance DS1 can be a distance in the first direction D1 between two first nozzles 513 adjacent to each other at an edge of the first blocker plate 5151. The second distance DS2 can be a distance in the first direction D1 between two first nozzles 513 adjacent to each other at (or near) a center of the first blocker plate 5151. The second distance DS2 can be greater than the first distance DS1. For example, the first distance DS1 can be less than the second distance DS2, and thus, the first deposition sources 51 can be more densely arranged at an edge of the first blocker plate 5151 than at a center of the first blocker plate 5151. However, for ease of illustration, embodiments in which the first deposition sources 51 have a single form are described below.

[0052] The second deposition sources 52 can be provided as a plurality. The second deposition sources 52 can be arranged along the first direction D1. For example, the substrate deposition apparatus SA (see, e.g., FIG. 1) can be a linear deposition module for linear deposition. When the second deposition sources 52 are provided as a plurality, the second nozzles 523 can also be provided as a plurality. The second nozzles 523 can be arranged along the first direction D1. Among the second deposition sources 52, a first distance DS1 (i.e., a separation distance in the first direction D1 between two second deposition sources 52 adjacent to an edge (or end) of the second blocker plate 5251) can be different from a second distance DS2 (i.e., a separation distance in the first direction D1 between two second deposition sources 52 at (or near) a center of the second blocker plate 5251). The first distance DS1 can be a distance in the first direction D1 between two second nozzles 523 adjacent to each other at an edge of the second blocker plate 5251. The second distance DS2 can be a distance in the first direction D1 between two second nozzles 523 adjacent to each other at a center of the second blocker plate 5251. The second distance DS2 can be greater than the first distance DS1. For example, the first distance DS1 can be less than the second distance DS2, and thus, the second deposition sources 52 can be more densely arranged at an edge of the second blocker plate 5251 than at a center of the second blocker plate 5251. However, for ease of illustration, embodiments in which the second deposition sources 52 have a single form are described below. Figure 1

[0053] ​Multiple third deposition sources 53 may be provided. The third deposition sources 53 may be arranged along the first direction D1. That is, the substrate deposition apparatus SA (see, for example...) Figure 1 The deposition source module 5 can be a linear deposition module for linear deposition. When multiple third deposition sources 53 are provided, multiple third nozzles 533 can also be provided. The third nozzles 533 can be arranged along a first direction D1. Among the third deposition sources 53, a first distance DS1 (i.e., the separation distance in the first direction D1 between two third deposition sources 53 adjacent to the edge of the third baffle plate 5351) can be different from a second distance DS2 (i.e., the separation distance in the first direction D1 between two third deposition sources 53 at (or near) the center of the third baffle plate 5351). The first distance DS1 can be the distance in the first direction D1 between two adjacent third nozzles 533 at the edge of the third baffle plate 5351. The second distance DS2 can be the distance in the first direction D1 between two adjacent third nozzles 533 at the center of the third baffle plate 5351. The second distance DS2 can be greater than the first distance DS1. For example, the first distance DS1 may be smaller than the second distance DS2, and therefore, the third deposition source 53 may be arranged more densely at the edge of the third barrier plate 5351 than at the center of the third barrier plate 5351. However, for ease of illustration, an embodiment of the third deposition source 53 having a single form is described below.

[0054] Multiple fourth deposition sources 54 may be provided. The fourth deposition sources 54 may be arranged along the first direction D1. That is, the substrate deposition apparatus SA (see, for example...) Figure 1 The deposition source module 5 can be a linear deposition module for linear deposition. When multiple fourth deposition sources 54 are provided, multiple fourth nozzles 543 can also be provided. The fourth nozzles 543 can be arranged along a first direction D1. Among the fourth deposition sources 54, a first distance DS1 (i.e., the separation distance in the first direction D1 between two fourth deposition sources 54 adjacent to the edge of the fourth baffle plate 5451) can be different from a second distance DS2 (i.e., the separation distance in the first direction D1 between two fourth deposition sources 54 at the center of the fourth baffle plate 5451). The first distance DS1 can be the distance in the first direction D1 between two adjacent fourth nozzles 543 at the edge of the fourth baffle plate 5451. The second distance DS2 can be the distance in the first direction D1 between two adjacent fourth nozzles 543 at the center of the fourth baffle plate 5451. The second distance DS2 can be greater than the first distance DS1. For example, the first distance DS1 may be smaller than the second distance DS2, and therefore, the fourth deposition source 54 may be arranged more densely at the edge of the fourth barrier plate 5451 than at the center of the fourth barrier plate 5451. However, for ease of illustration, an embodiment in which the fourth deposition source 54 has a single form will be described below.

[0055] Figure 7 A flowchart illustrating steps of a substrate deposition method according to an embodiment of the disclosure is described.

[0056] Reference is made to Figure 7 A substrate deposition method S according to an embodiment can be provided. According to the substrate deposition method S, a deposition layer can be formed on a substrate by using a substrate deposition apparatus SA (see, for example, Figures 1 to 6 described below. The substrate deposition method S can include placing a substrate in a substrate deposition apparatus (S1) and performing a deposition process on the substrate (S2). Figure 1 Performing a deposition process on the substrate (S2) can include heating a deposition source module (S21) and moving the deposition source module (S22).

[0057] Hereinafter, the substrate deposition apparatus SA described below will be described in more detail.

[0058] Figures 8 to 11 The substrate deposition method S described below will be described in more detail. Figure 7

[0059] A diagram illustrating steps of a substrate deposition method according to a flowchart in Figures 8 to 11 Figure 7 A substrate W can be disposed on a stage 3 by placing a substrate in a substrate deposition apparatus (S1) with reference to

[0060] Figure 7 , Figure 8 and Figure 9 Heating a deposition source module (S21) can include heating a deposition source module by using a first heater 517 (see, for example, Figure 8

[0061] Heating a deposition source module (S21) can include heating a deposition source module by using a second heater 527 (see, for example, Figure 8 Figure 10 Figure 11 Heating a deposition source module (S21) can include heating a deposition source module by using a third heater 537 (see, for example, Figure 3 Figure 3 Figure 3 Heating a deposition source module (S21) can include heating a deposition source module by using a fourth heater 547 (see, for example, Figure 3 ​​​​​​​​) to increase the temperature of the first deposition material 519, the second deposition material 529, the third deposition material 539, and / or the fourth deposition material 549. The first deposition source 51 and the second deposition source 52 can be heated at different temperatures from each other. In one embodiment, the first deposition source 51 can be heated at a first temperature, and the second deposition source 52 can be heated at a second temperature. The first temperature can be different from the second temperature. As an example, the first temperature can be in a range from about 200°C to about 400°C; however, the present disclosure should not be limited thereto or thereby. In the above description, an embodiment in which the temperature of the first deposition material 519, the second deposition material 529, the third deposition material 539, and / or the fourth deposition material 549 is increased differently is described, but the present disclosure should not be limited thereto or thereby.

[0062] During the heating of the deposition source module (S21), the first deposition material 519 stored in the first deposition source 51 can be evaporated and can be discharged to the outside through the first nozzle 513. The first deposition material 51a discharged through the first nozzle 513 can reach the lower surface Wb of the substrate W after passing through the first blocking plate 5151. That is, the evaporated first deposition material 51a can be deposited on the substrate W.

[0063] During the heating of the deposition source module (S21), the second deposition material 529 stored in the second deposition source 52 can be evaporated and can be discharged to the outside through the second nozzle 523. The second deposition material 52a discharged through the second nozzle 523 can reach the lower surface Wb of the substrate W after passing through the second blocking plate 5251. That is, the evaporated second deposition material 52a can be deposited on the substrate W.

[0064] During the heating of the deposition source module (S21), the third deposition material 539 stored in the third deposition source 53 can be evaporated and can be discharged to the outside through the third nozzle 533. The third deposition material 53a discharged through the third nozzle 533 can reach the lower surface Wb of the substrate W after passing through the third blocking plate 5351. That is, the evaporated third deposition material 53a can be deposited on the substrate W.

[0065] During the heating of the deposition source module (S21), the fourth deposition material 549 stored in the fourth deposition source 54 can be evaporated and can be discharged to the outside through the fourth nozzle 543. The fourth deposition material 54a discharged through the fourth nozzle 543 can reach the lower surface Wb of the substrate W after passing through the fourth blocking plate 5451. That is, the evaporated fourth deposition material 54a can be deposited on the substrate W.

[0066] The second deposited material 52a evaporated from the substrate W can reach a first area where the substrate W is located, and the fourth deposited material 54a evaporated from the substrate W can reach a second area where the substrate W is located. The first area can have the same size as the second area; however, the present disclosure should not be limited thereto or thereby. According to an embodiment, the first area can partially overlap the second area. According to an embodiment, the first area can completely overlap the second area, and the first area can be identical to the second area. The third deposited material 51a evaporated from the substrate W can reach a third area where the substrate W is located, and the third area can be narrower than the first area.

[0067] By moving the deposition source module (S22), the heated deposition source module 5 can be moved in a direction parallel to the second direction D2. Accordingly, the deposition layer can be completely formed on the lower surface Wb of the substrate W.

[0068] According to the substrate deposition apparatus and the substrate deposition method using the same, four deposition sources can be used for deposition on the substrate W, and thus various deposition structures can be implemented. In such an embodiment, when the second deposited material is identical to the fourth deposited material, the durability of the deposition layer can be improved, and the lifespan of a manufactured product can be extended.

[0069] According to the substrate deposition apparatus and the substrate deposition method using the same, a plurality of deposition sources including the same deposited material can be provided. For example, a linear deposition method can be implemented. Accordingly, the deposition layer can be deposited on the entire substrate at once, and thus the process can be quickly performed.

[0070] According to the substrate deposition apparatus and the substrate deposition method using the same, the deposition sources can be more densely arranged at the edges (or ends) than at the center. Accordingly, a phenomenon in which the thickness of the deposition layer is reduced at the edges of the substrate can be prevented, and thus the deposition layer can be more uniformly formed.

[0072] In Figure 12 , identical reference numerals indicate identical elements in Figures 1 to 11 , and thus detailed descriptions of the same elements will be omitted or simply repeated.

A width of the second blocking hole (e.g., second blocking opening) 5251h' in the second blocking plate 5251' can be referred to as a second width w2'. Unlike the description with reference to Figure 3 , the second width w2' can be substantially the same or similar to the first width w1'.

A width of the third blocking hole (e.g., third blocking opening) 5351h' in the third blocking plate 5351' can be referred to as a third width w3'. The third width w3' can be different from the first width w1'. As an example, the third width w3' can be greater than the first width w1'.

[0077] The fourth deposition source 54' can comprise a fourth blocking plate 5451'. A width of the fourth blocking hole (e.g., fourth blocking opening) 5451h' in the fourth blocking plate 5451' can be referred to as a fourth width w4'. Unlike the description with reference to Figure 3 , the fourth width w4' can be substantially the same or similar to the third width w3'.

According to an embodiment, the shutter 8 can be movable in a direction parallel to the second direction D2 to selectively cover at least one of the first deposition source 51", the second deposition source 52", the third deposition source 53", and the fourth deposition source 54".

[0081] According to the substrate deposition apparatus and the substrate deposition method using the same, a shutter can be used to cover a deposition source not in use. Accordingly, various deposition layers can be implemented with a single deposition source module.

[0082] Figure 14 FIG. 6 is a cross-sectional view of a deposition source module according to an embodiment of the present disclosure.

[0083] In Figure 14 , identical reference numerals are used to designate the same elements as those in Figures 1 to 13 , and thus, detailed descriptions of the same elements will be omitted or simply repeated.

[0084] Referring to Figure 14 , a deposition source module 5”’ can be provided. The deposition source module 5”’ can include a first deposition source 51”’, a second deposition source 52”’, a third deposition source 53”’, and a fourth deposition source 54”’.
