Moreover, for brevity, some elements can be suitably omitted in the figures.

[0026] FIG. 1 is a schematic diagram of a deposition apparatus E according to an embodiment of the disclosure. The deposition apparatus E can deposit on the substrate of various electronic devices. For example, the electronic devices can include a display device, a backlight device, an antenna device, a sensing device, a tiled device, or the combination thereof, but it is not limited thereto. The display device can be a non-self-emitting type display device or a self-emitting type display device. The antenna device can be a liquid crystal type antenna device or a non-liquid crystal type antenna device. The sensing device can be a sensing device for sensing capacitance, light, heat, or ultrasonic, but it is not limited thereto. The tiled device can be a tiled display device or a tiled antenna device, but it is not limited thereto. The electronic device can be a bendable electronic device or a flexible electronic device. The electronic device can include a passive element and an active element, such as a capacitance, a resistance, an inductance, a diode, a transistor, or etc. The diode can include a light-emitting diode or a photoelectric diode. For example, the light-emitting diode can include an organic light-emitting diode (OLED), a mini LED, a micro LED, or a quantum dot LED, but it is not limited thereto. It should be noted that, the electronic device can be a combination having one or more aforementioned devices, but it is not limited thereto.

[0027] The deposition apparatus E primarily includes a deposition chamber 100, a target 200, a substrate holder 300, and an adjustment plate 400. The deposition chamber 100 has an inner space 110. The target 200, the substrate holder 300, and the adjustment plate 400 can be disposed in the inner space 110. The adjustment plate 400 can be disposed between the target 200 and the substrate holder 300. As shown in FIG. 2. When the user uses the deposition apparatus E to deposit on a substrate S, the substrate S can be disposed on the substrate holder 300, and the material of the target 200 can pass through the adjustment plate 400 and fall on the substrate S to form a coated film on the substrate S.

[0028] The substrate holder 300 includes a base portion 310, a first supporting portion 320, and a second supporting portion 330. The base portion 310 has a flat surface 311 facing the target 200, and the first supporting portion 320 and the second supporting portion 330 are disposed on the flat surface 311 and protrude therefrom. In this embodiment, the first supporting portion 320 and the second supporting portion 320 are adjacent to each other, the first supporting portion 320 has a curved surface 321, and the second supporting portion 330 has an inclined surface 331. Thus, the curved surface 321 and the inclined surface 331 can be connected to each other, and an included angle ? can be formed between the inclined surface 331 and the flat surface 311 of the base portion 310.

[0029] The substrate S has a curved surface section S1 and a flat surface section S2. The curvature of the curved surface 321 of the first supporting portion 320 matches the curvature of the curved surface section S1, and the slope of the inclined surface 321 of the second supporting portion 330 matches the slope of the flat surface section S2. Therefore, when the substrate S is disposed on the substrate holder 300, the curved surface section S1 and the flat surface section S2 are respectively in contact with and attached to the curved surface 321 of the first supporting portion 320 and the inclined surface 331 of the second supporting portion 330. The included angle ? is also formed between the flat surface section S2 of the substrate S and the flat surface 311 of the base portion 310. For example, the inclined angle ? can be greater than 0 degrees and less than 90 degrees, but it is not limited thereto. In some embodiments, the included angle ? can be ranged from 1 degree to 50 degrees (1??included angle ??50?).

[0030] Owing to the aforementioned structure of the substrate holder 300, the curved surface section S1 can be prevented from blocking when the substrate S is to be deposited. Thereby, the film thickness on every portions of the substrate S is substantially uniform, or the color difference of the substrate S after the film is coated can be reduced. For example, the difference of the film thickness on the curved surface section S1 of the substrate S and the film thickness on the flat surface section S2 of the substrate S can be less than or equal to 10% (such as be ranged from 0.5% to 10% (0.5%?the difference of the film thickness?10%)), but it is not limited thereto.

[0031] In this embodiment, the first supporting portion 320 and the second supporting portion 330 can affixed to the base portion 310 independently. Therefore, when the user wants to deposit on a substrate that has the curved surface section with different curvature and/or the flat surface section with different slop, the first supporting portion 320 and/or the second supporting portion 330 can be detached from the base portion 310 and replaced by the first supporting portion having the corresponding curvature and/or the second supporting portion having the corresponding slope. Therefore, it is facilitated the usage of the deposition apparatus E or the cost of deposition by using the deposition apparatus E can be reduced.

[0032] Although there is one target, one substrate holder, and one adjustment plate disposed in one deposition chamber shown in FIG. 1 and FIG. 2, a plurality of targets, multiple substrate holders, and multiple adjustment plates can be disposed in one deposition chamber in some embodiments (not shown). Thus, the speed and the yield of forming a film with multiple layers can be facilitated. In detail, the multiple targets can be disposed in the deposition chamber. Each of the substrate holders can include a base portion having a flat surface, a first supporting portion having a curved surface and disposed on the flat surface of the base portion, and a second supporting portion disposed on the flat surface of the base portion and protruding therefrom, as mentioned before. The multiple adjustment plates are disposed in the deposition chamber, and each adjustment plate is disposed between one of the multiple targets and one of the substrate holders.

[0033] Referring to FIG. 3A to FIG. 3D, in some embodiments, the deposition apparatus E includes a plurality of pad units 500 disposed on the substrate holder 300. In detail, each of the pad units 500 includes a pad base 510, a pad 520, and at least one spring 530. The pad base 510 can pass through the hole H on the substrate holder 300 and can be exposed from the surface that is configured to be in contact with the substrate S (i.e. the curved surface 321 and the inclined surface 331). The pad 520 is disposed on the pad base 510 and has an adhesive material. Therefore, when the substrate S is disposed on the base holder 300, the substrate S is in contact with the pad 520, and the firmness of affixing the substrate S to the substrate holder 300 can be enhanced. An end of the spring 530 is connected to the pad base 510, and the other end of the spring 530 is connected to the deposition chamber 100 or the base portion 310. The spring 530 can provide a buffer when a vibration is generated during the film is coated on the substrate S.

[0034] Referring to FIG. 3E, in some embodiments, each of the pad units 500 further includes a vacuum suction hole 540. The vacuum suction hole 540 can penetrate the pad base 510 and the pad 520, and connect to a vacuum generator (not shown). Therefore, when the substrate S is disposed on the substrate holder 300, the vacuum generator can pump out from the vacuum suction hole 540, and the substrate S can be affixed to the substrate holder 300 more steadily.

[0035] It should be noted that, the number and the arrangement of the pad units 500 can be adjusted as required. The number and the arrangement shown in FIG. 3A, FIG. 3B, or FIG. 3C is merely an example, it is not limited thereto.

[0036] Referring to FIG. 4, in this embodiment, the adjustment plate 400 includes at least one fixed portion 410, at least one frame portion 420, a plurality of fin portions 430, and a plurality of fixing members 440. The fixed portion 410 is affixed to the wall 120 of the deposition chamber 100. The frame portion 420 includes a first side 421 and a second side 422, the first side 421 faces the wall 120 of the deposition chamber 100, and the second side 422 is opposite to the first side 421. Therefore, the distance D1 between the first side 421 and the wall 120 of the deposition chamber 100 is less than or equal to the distance D2 between the second side 422 and the wall 120 of the deposition chamber 100. The fixed portion 410 is connected to the first side 421 of the frame portion 420, thus, the frame portion 420 can be affixed to the deposition chamber 100 via the fixed portion 410 and hung in the inner space 110 of the deposition chamber 100.

[0037] A plurality of first holes 423 are formed on the frame portion 420, and each of the pin portions 430 has a second hole 431. Each fixing member 400 (such as a screw, a pin, or a rivet) can pass through the second hole 430 of the corresponding fin portion 430 and one of the first holes 423 to affix the fin portion 430 to the frame portion 420. When the fin portions 430 are affixed to the frame portion 420, the fin portions 430 can protrude from the second side 422 of the frame portion 420, so that it can block some material of the target 200 when the film is coated on the substrate S.

[0038] In this embodiment, the first holes 423 are arranged in matrix, so that at least a portion of the first holes 423 are arranged along a direction D from the first side 421 to the second side 422 of the frame 420 (i.e. the Y-axis in the figures). Thus, the lengths of the fin portions 430 can be the same, and the user can adjust the length of each fin portion 430 protruding from the second side 422 by passing the fixing member 440 through the different first holes 423 in the direction D. Moreover, each second hole 430 can include a longitudinal structure along the direction D, so as to further slightly adjust the length of each fin portion 430 protruding from the second side 422.

[0039] The length of each fin portion 430 protruding from the second side 422 can be determined by the corresponding portion of the substrate S and the consumption of the target 200. For example, in this embodiment, the lengths L1 of the fin portions 430 protruding from the second side 422, which correspond to the curved surface 321 of the first supporting portion 320 (i.e. correspond to the curved surface section S1 of the substrate S), is less than or equal to the lengths L2 of the fin portions 430 protruding from the second side 422, which correspond to the inclined surface 331 of the second supporting portion 330 (i.e. correspond to the flat surface section S2 of the substrate S). Therefore, more material of the target 200 can be fallen on the curved surface section S1 during the deposition, and the uneven problem of the film thickness can be reduced.

[0040] Referring to FIG. 5, in another embodiment of the disclosure, a deposition apparatus E primarily includes a deposition chamber 100, a target 200, a substrate holder 300, and an adjustment plate 400. The structures of the deposition chamber 100, the target 200, the substrate holder 300, and the adjustment plate 400 of the deposition apparatus E are substantially the same as the structures of the deposition chamber 100, the target 200, the substrate holder 300, and the adjustment plate 400 of the deposition apparatus E, so that the features thereof are not repeated in the interest of brevity.

[0041] Specifically, in this embodiment, the first supporting portion 320 and the second supporting portion 330 of the substrate holder 300 are integrally formed as one piece, so that the supporting strength for the substrate S can be increased.

[0042] Referring to FIG. 6, in another embodiment of disclosure, a deposition apparatus E primarily includes a deposition chamber 100, a target 200, a substrate holder 300, and an adjustment plate 400, and the substrate holder 300 includes a base portion 310, a first supporting portion 320, and a second supporting portion 330. The structures of the deposition chamber 100, the target 200, the adjustment plate 400, and the first supporting portion 320 of the deposition apparatus E are substantially the same as the structures of the deposition chamber 100, the target 200, the adjustment plate 400, and the first supporting portion 320 of the deposition apparatus E, so that the features thereof are not repeated in the interest of brevity.

[0043] In this embodiment, the second supporting portion 330 is disposed on and protrudes from the flat surface 311 of the base portion 310. A gap is formed between the second supporting portion 330 and the first supporting portion 320. When the substrate S is disposed on the substrate holder 300, the second supporting portion 330 can be in contact with the flat surface section S2 of the substrate S and raise the flat surface section S2 of the substrate S, and the flat surface section S2 of the substrate S is inclined relative to the flat surface 311 of the base portion 310 accordingly. An included angle ? is formed between the inclined flat surface section S2 and the flat surface 311 of the base portion 310. The included angle ? can be greater than 0 degrees and less than or equal to 90 degrees (such as be ranged from 1 degree to 50 degrees).

[0044] Owing to the aforementioned structures of the deposition apparatus E, the cost of the deposition apparatus E can be further saved, and the uneven problem of the film thickness of the substrate S can be still solved by using the deposition apparatus E.

[0045] Although there is one target, one substrate holder, and one adjustment plate disposed in one deposition chamber shown in FIG. 5 and FIG. 6, multiple targets, multiple substrate holders, and multiple adjustment plates can be disposed in one deposition chamber in some embodiments (not shown). Thus, the speed and the yield of forming a film with multiple layers can be facilitated. In detail, the multiple targets can be disposed in the deposition chamber. Each of the substrate holders can include a base portion having a flat surface, a first supporting portion having a curved surface and disposed on the flat surface of the base portion, and a second supporting portion disposed on the flat surface of the base portion and protruding therefrom, as mentioned before. The multiple adjustment plates are disposed in the deposition chamber, and each adjustment plate is disposed between one of the multiple targets and one of the substrate holders.

[0046] In another embodiment of the disclosure, the deposition apparatus E includes a deposition chamber, ate least one substrate holder, multiple targets, and multiple adjustment plate. The deposition method of using the deposition apparatus E includes the steps of disposing at least one substrate on at least one substrate holder before the substrate entering the deposition chamber and forming at least one substrate chamber with the substrate. As mentioned before, if the at least one substrate includes a flat surface section and a curved surface section, the at least one substrate holder can be configured as the design in FIG. 1, FIG. 2, FIG. 5, or FIG. 6. An included angle ? can be formed between the flat surface section and the flat surface of the at least one substrate holder, and the included angle ? is greater than 0 degrees and less than or equal to 90 degrees (for example, the included angle ? can be ranged from 1 degree to 50 degrees).

[0047] Referring to FIG. 7A, a deposition chamber 100A is provided, wherein a first target 200A, a second target 200B, a first adjustment plate 400A, and a second adjustment plate 400B are disposed inside the deposition chamber 100A. A substrate holder with the substrate (such as a substrate holder 300 with the substrate S shown in FIG. 7A) can be transferred into the deposition chamber 100A, then the substrate holder 300 with the substrate S can be rotated to a position corresponding to the first target 200A, and the first adjustment plate 400A can be disposed between the first target 200A and the substrate holder 300 with the substrate S. After that, a deposition process can be started. The material of the first target 200A can pass through the first adjustment plate 400A and deposit on the substrate S.

[0048] The structure of the first adjustment plate 400A can be similar to the structure of the adjustment plate 400 of the deposition apparatus E, and the structure of the substrate holder 300 can be similar to the structure of the substrate holder 300 of the deposition apparatus E.

[0049] Subsequently, as shown in FIG. 7B, the substrate holder 300 with the substrate S can be rotated to let the substrate S move from the position corresponding to the first target 200A to a position corresponding to the second target 200B, and the second adjustment plate 400B can be disposed between the second target 200B and the at least one substrate holder 300 with the substrate S. After that, a deposition process can be started. The material of the second target 200B can pass through the second adjustment plate 400B and deposit on the material of the first target 200A which is on the substrate S. For example, the rotating speed of the substrate holder 300 can be ranged from 40 rpm (revolutions per minute) to 60 rpm.

[0050] Therefore, the deposition apparatus E can deposit a plurality of layers with different targets on the substrate S. It should be noted that, although the deposition apparatus E in this embodiment takes an example in that two layers of targets including the first target 200A and the second target 200B are deposited on the substrate S, it is not limited thereto. The user can add the third or more adjustment plates and the third or more targets in the deposition apparatus as required, but it is not limited thereto. Moreover, in the deposition apparatus E, after the material of the second target 200B is deposited on the material of the first target 200A that is on the substrate S, the substrate holder 300 can rotate again to let the substrate S move to the position corresponding to the first target 200A, and the first adjustment plate 400A is disposed between the first target 200A and the substrate holder 300 with the substrate S. After that, a deposition process can be further started. The material of the first target 200A can pass through the first adjustment plate 400A again and deposit on the material of the second target 200B that is on the substrate S.

[0051] Although there is two targets, one substrate holder, and two adjustment plates disposed in one deposition chamber shown in FIG. 7A and FIG. 7B, multiple targets, multiple substrate holders, and multiple adjustment plates can be disposed in one deposition chamber in some embodiments (not shown). Thus, the speed and the yield of forming a film with multiple layers can be facilitated. In detail, the multiple targets can be disposed in the deposition chamber. Each of the substrate holders can include a base portion having a flat surface, a first supporting portion having a curved surface and disposed on the flat surface of the base portion, and a second supporting portion disposed on the flat surface of the base portion and protruding therefrom, as mentioned before. The multiple adjustment plates are disposed in the deposition chamber, and each adjustment plate is disposed between one of the multiple targets and one of the substrate holders. In some embodiments (not shown), the deposition apparatus can includes multiple deposition chambers, multiple substrate holders, multiple targets, and multiple adjustment plates. In one of the multiple deposition chambers, one target, one adjustment plate, and one substrate holder can be disposed therein. The structure of each of the adjustment plates can be similar to the structure of the adjustment plate of the aforementioned deposition apparatus, and the structure of each of the substrate holders can be similar to the structure of the substrate holder of the aforementioned deposition apparatus.

[0052] The features between the aforementioned embodiments can be used or combined as long as they do not violate or conflict the spirit of the present application.

[0053] In summary, an embodiment of the disclosure provides a deposition apparatus, including a deposition chamber, at least one target, at least one substrate holder, and at least one adjustment plate. The at least one target, the at least one substrate holder, and the at least one adjustment plate are disposed in the deposition chamber, and the at least one adjustment plate is disposed between the at least one target and the at least one substrate holder. The at least one substrate holder includes a base portion, a first supporting portion, and a second supporting portion. The base portion has a flat surface.
