近年來,存在以下的市場需求:代替玻璃基板而使用具有撓性的樹脂基板作為電子元件用的基板。這樣的樹脂基板例如使用聚醯亞胺膜。例如,聚醯亞胺膜是在基板上塗布聚醯亞胺的前驅體的溶液後、經過對所述基板進行加熱的工程(加熱工程)而形成的。作為聚醯亞胺的前驅體的溶液,例如存在由聚醯胺酸與溶劑構成的聚醯胺酸清漆(例如參照專利文獻1以及專利文獻2)。 現有技術文獻In recent years, there has been a market demand to use a flexible resin substrate as a substrate for electronic components instead of a glass substrate. As such a resin substrate, a polyimide film is used, for example. For example, a polyimide film is formed by applying a solution of a precursor of polyimide on a substrate, and then going through a process (heating process) of heating the substrate. As a solution of a precursor of polyimide, for example, there is a polyamic acid varnish composed of polyamic acid and a solvent (for example, refer to Patent Document 1 and Patent Document 2). prior art literature

發明要解決的技術問題The technical problem to be solved by the invention

然而,上述的加熱工程包括:使溶劑在較低溫度下蒸發的第一工程與使聚醯胺酸在較高溫度下固化的第二工程。考慮在第二工程中,使用紅外線加熱器,能夠通過紅外線加熱基板。作為紅外線加熱器,例如已知有呈W型或U型的紅外線加熱器(例如參照專利文獻3)。但是,W型或U型的紅外線加熱器,露出以向外側凸出的方式彎折的部分,露出的部分與其他部分相比會降溫,因此在提高紅外線加熱器的溫度分佈的平衡方面存在問題。However, the above-mentioned heating process includes a first process of evaporating the solvent at a lower temperature and a second process of curing the polyamic acid at a higher temperature. In the second process, it is considered that an infrared heater is used, and the substrate can be heated by infrared rays. As an infrared heater, for example, a W-shaped or U-shaped infrared heater is known (for example, refer to Patent Document 3). However, in the W-shaped or U-shaped infrared heaters, a portion that is bent so as to protrude outward is exposed, and the exposed portion is lowered in temperature compared with other portions, so there is a problem in improving the balance of the temperature distribution of the infrared heater. .

鑒於以上那樣的情況,本發明的目的在於提供一種基板加熱裝置、基板加熱方法以及紅外線加熱器,能夠提高紅外線加熱器的溫度分佈的平衡。 用於解決上述技術問題的方案In view of the above circumstances, an object of the present invention is to provide a substrate heating apparatus, a substrate heating method, and an infrared heater capable of improving the balance of the temperature distribution of the infrared heater. Solutions for solving the above technical problems

本發明的一方案的基板加熱裝置,其特徵在於,包括:減壓部,對塗布了溶液的基板的容納空間的氛圍進行減壓;及紅外線加熱器,能夠通過紅外線加熱所述基板,所述紅外線加熱器呈在多個部位彎折的管狀,並且包括:彎曲部,以向外側凸出的方式彎折;及蓋部,配置為從外側覆蓋所述彎曲部的至少一部分。A substrate heating apparatus according to an aspect of the present invention is characterized by comprising: a decompression unit for depressurizing the atmosphere of the accommodation space of the substrate to which the solution has been applied; and an infrared heater capable of heating the substrate by infrared rays, and the The infrared heater has a tubular shape bent at a plurality of places, and includes a bent portion bent so as to protrude outward, and a cover portion arranged to cover at least a part of the bent portion from the outside.

根據該構成,因為紅外線加熱器包括配置為從外側覆蓋彎曲部的至少一部分的蓋部,所以能夠避免彎曲部露出,從而能夠抑制彎曲部與其他部分相比發生降溫。即,因為通過蓋部能夠從外側加熱彎曲部的至少一部分,所以能夠抑制彎曲部與其他部分產生溫度差。因此,能夠提高紅外線加熱器的溫度分佈的平衡。According to this configuration, since the infrared heater includes the cover portion arranged to cover at least a part of the curved portion from the outside, exposure of the curved portion can be avoided, and the temperature of the curved portion can be suppressed from being lowered compared to other portions. That is, since at least a part of the curved portion can be heated from the outside by the cover portion, it is possible to suppress a temperature difference between the curved portion and other portions. Therefore, the balance of the temperature distribution of the infrared heater can be improved.

也可以是,在上述的基板加熱裝置中,所述紅外線加熱器還包括多個直部,所述多個直部在第一方向上具有長邊,並且在與所述第一方向交叉的第二方向上並列配置,所述彎曲部連結相鄰的2個所述直部的端部,所述蓋部以從外側覆蓋多個所述彎曲部的方式在所述第二方向上直線狀地延伸。 根據該構成,蓋部以從外側覆蓋多個彎曲部的方式在第二方向上直線狀地延伸,由此能夠一併地避免多個彎曲部露出,因此能夠一併地抑制多個彎曲部與其他部分相比發生降溫。即,因為通過蓋部能夠從外側一併地加熱多個彎曲部,所以能夠抑制多個彎曲部與其他部分產生溫度差。因此,能夠有效地提高紅外線加熱器的溫度分佈的平衡。此外,紅外線加熱器還包括多個直部,由此多個直部彼此相鄰,能夠提高相互的發熱溫度,因此能夠在較高溫度下提高紅外線加熱器的溫度分佈的平衡,所述多個直部在第一方向上具有長邊,並且並列地配置在與第一方向交叉的第二方向上。In the above-mentioned substrate heating device, the infrared heater may further include a plurality of straight portions having long sides in the first direction, and may be formed on a second portion intersecting the first direction. They are arranged in parallel in two directions, the curved portion connects the ends of the two adjacent straight portions, and the cover portion is linearly formed in the second direction so as to cover the plurality of curved portions from the outside. extend. According to this configuration, since the cover portion extends linearly in the second direction so as to cover the plurality of curved portions from the outside, exposure of the plurality of curved portions can be collectively avoided, and therefore, the plurality of curved portions can be collectively suppressed from being exposed to the Cooling compared to other parts. That is, since the plurality of curved portions can be collectively heated from the outside by the cover portion, it is possible to suppress a temperature difference between the plurality of curved portions and other portions. Therefore, the balance of the temperature distribution of the infrared heater can be effectively improved. In addition, the infrared heater further includes a plurality of straight portions, whereby the plurality of straight portions are adjacent to each other, and the mutual heat generation temperature can be increased, so that the balance of the temperature distribution of the infrared heater can be improved at a higher temperature, the plurality of The straight portions have long sides in the first direction, and are arranged in parallel in the second direction intersecting with the first direction.

也可以是,在上述的基板加熱裝置中,所述蓋部與彎曲部之間的間隔比相鄰的2個所述直部之間的間隔小。 根據該構成,與使蓋部與彎曲部之間的間隔為相鄰的2個直部之間的間隔以上的情況相比較,能夠更可靠地避免彎曲部露出,因此能夠更可靠地抑制彎曲部與其他部分相比發生降溫。即,因為通過蓋部能夠從外側更可靠地加熱彎曲部的至少一部分,所以能夠更可靠地抑制彎曲部與其他部分產生溫度差。因此,能夠更可靠地提高紅外線加熱器的溫度分佈的平衡。In the above-mentioned substrate heating apparatus, the interval between the cover portion and the curved portion may be smaller than the interval between the two adjacent straight portions. According to this configuration, as compared with the case where the interval between the cover portion and the curved portion is set to be equal to or greater than the interval between two adjacent straight portions, exposure of the curved portion can be avoided more reliably, and thus the curved portion can be suppressed more reliably. Cooling occurs compared to other parts. That is, since at least a part of the curved part can be more reliably heated from the outside by the cover part, the temperature difference between the curved part and other parts can be suppressed more reliably. Therefore, the balance of the temperature distribution of the infrared heater can be improved more reliably.

也可以是,在上述的基板加熱裝置中,所述紅外線加熱器還包括:第一導入部,設置在所述紅外線加熱器的一端;第二導入部,設置在所述紅外線加熱器的另一端,所述第一導入部以及所述第二導入部的至少一方設置在所述蓋部的端部。 然而,若第一導入部與第二導入部過於接近,則存在該部分的溫度比其他部分的溫度更為降溫的傾向。但是,根據該構成,因為第一導入部與第二導入部一定程度地遠離,所以能夠抑制紅外線加熱器局部地降溫。因此,能夠提高紅外線加熱器的溫度分佈的平衡。In the above-mentioned substrate heating device, the infrared heater may further comprise: a first introduction part provided at one end of the infrared heater; and a second introduction part provided at the other end of the infrared heater and at least one of the first introduction portion and the second introduction portion is provided at an end of the cover portion. However, when the first introduction part and the second introduction part are too close, the temperature of the part tends to drop more than the temperature of the other parts. However, according to this structure, since the 1st introduction part and the 2nd introduction part are spaced apart to some extent, it is possible to suppress the local temperature drop of the infrared heater. Therefore, the balance of the temperature distribution of the infrared heater can be improved.

也可以是,在上述的基板加熱裝置中,在俯視狀態下,所述紅外線加熱器的外形呈矩形形狀,所述第一導入部以及所述第二導入部在所述紅外線加熱器的一邊的中央部對置地配置。 根據該構成,因為第一導入部與第二導入部一定程度地遠離,所以能夠抑制紅外線加熱器局部地降溫。因此,能夠提高紅外線加熱器的溫度分佈的平衡。In the above-mentioned substrate heating apparatus, the outer shape of the infrared heater may be a rectangular shape in a plan view, and the first introduction portion and the second introduction portion may be on one side of the infrared heater. The central parts are arranged to face each other. According to this structure, since the 1st introduction part and the 2nd introduction part are spaced apart to some extent, it can suppress that an infrared heater is cooled locally. Therefore, the balance of the temperature distribution of the infrared heater can be improved.

也可以是,在上述的基板加熱裝置中,在俯視狀態下,所述紅外線加熱器的外形呈矩形形狀,所述第一導入部配置在所述紅外線加熱器的一邊的一側,所述第二導入部配置在所述一邊的另一側。 根據該構成,因為紅外線加熱器中的從第一導入部或者第二導入部中的任一個到彎曲部的部分為在2個部位彎折的U字管狀(即沿著除了紅外線加熱器的所述一邊以外的三邊的形狀),所以與直管狀以及L字管狀的情況相比較,能夠提高紅外線加熱器的柔軟性。因此,即便紅外線加熱器的所述一邊熱膨脹或者熱收縮,也能夠利用紅外線加熱器的柔軟性來容許所述一邊的膨脹或者收縮。In the above-mentioned substrate heating apparatus, the outer shape of the infrared heater may be a rectangular shape in a plan view, the first introduction portion may be arranged on one side of the infrared heater, and the first introduction portion may be arranged on one side of the infrared heater. The two introduction parts are arranged on the other side of the one side. According to this configuration, the portion of the infrared heater from either the first introduction portion or the second introduction portion to the bent portion is in the shape of a U-shaped tube bent at two places (that is, along all parts except the infrared heater). The shape of the three sides other than the one side mentioned above), the flexibility of the infrared heater can be improved compared with the case of the straight tube shape and the L-shaped tube shape. Therefore, even if the one side of the infrared heater thermally expands or contracts, the flexibility of the infrared heater allows the expansion or contraction of the one side to be tolerated.

也可以是,在上述的基板加熱裝置中,在俯視狀態下,所述紅外線加熱器的外形呈矩形形狀,所述第一導入部配置在所述紅外線加熱器的一角部,所述第二導入部配置在所述一角部的對角部。 根據該構成,在俯視狀態下,第一導入部以及第二導入部的配置位置是以紅外線加熱器的中心為基準成為點對稱,並且第一導入部以及第二導入部較遠地遠離。由此,即便在第一導入部以及第二導入部比其他部分降溫的情況下,也不會降低相互的降溫溫度,從而能夠避免紅外線加熱器局部地過度降溫,因此能夠盡可能地提高紅外線加熱器的溫度分佈的平衡。In the above-mentioned substrate heating apparatus, the outer shape of the infrared heater may be a rectangular shape in a plan view, the first introduction portion may be arranged at a corner of the infrared heater, and the second introduction may be The part is arranged at a diagonal part of the one corner part. According to this configuration, in a plan view, the arrangement positions of the first introduction portion and the second introduction portion are point-symmetrical with respect to the center of the infrared heater, and the first introduction portion and the second introduction portion are far away from each other. Thereby, even when the temperature of the first introduction part and the second introduction part is lower than that of the other parts, the mutual cooling temperature is not lowered, and the temperature of the infrared heater can be prevented from being locally excessively lowered, so that the infrared heating can be improved as much as possible. balance of the temperature distribution of the device.

也可以是,在上述的基板加熱裝置中,在俯視狀態下,所述紅外線加熱器呈點對稱形狀。 根據該構成,與在俯視狀態下紅外線加熱器呈非對稱形狀的情況相比較,能夠更可靠地提高紅外線加熱器的溫度分佈的平衡。In the above-mentioned substrate heating apparatus, the infrared heater may have a point-symmetric shape in a plan view. According to this configuration, the balance of the temperature distribution of the infrared heater can be improved more reliably than when the infrared heater has an asymmetric shape in a plan view.

也可以是,在上述的基板加熱裝置中,在俯視狀態下,所述紅外線加熱器的外形呈矩形形狀,所述第一導入部以及所述第二導入部鄰接地配置於所述紅外線加熱器的一角部。 根據該構成,因為第一導入部以及第二導入部之間的距離變得最小,所以能夠盡可能地抑制紅外線加熱器的熱膨脹或者熱收縮。In the above-mentioned substrate heating apparatus, the infrared heater may have a rectangular shape in a plan view, and the first introduction portion and the second introduction portion may be arranged adjacent to the infrared heater. corner of . According to this configuration, since the distance between the first introduction portion and the second introduction portion is minimized, thermal expansion or thermal contraction of the infrared heater can be suppressed as much as possible.

也可以是,在上述的基板加熱裝置中,在俯視狀態下,所述第一導入部以及所述第二導入部的至少一部分進入所述紅外線加熱器的外部形狀內。 根據該構成,因為在配置紅外線加熱器時能夠避免第一導入部以及第二導入部成為妨礙,所以能夠提高佈局的自由度。例如,在一表面上鋪設多個紅外線加熱器時,能夠避免相鄰的2個紅外線加熱器在第一導入部以及第二導入部處發生干涉,因此能夠整齊地鋪設多個紅外線加熱器。In the above-mentioned substrate heating apparatus, at least a part of the first introduction part and the second introduction part may enter into the outer shape of the infrared heater in a plan view. According to this configuration, the first introduction portion and the second introduction portion can be prevented from being obstructed when the infrared heater is arranged, so that the degree of freedom of layout can be improved. For example, when laying a plurality of infrared heaters on one surface, it is possible to avoid the interference of two adjacent infrared heaters in the first introduction part and the second introduction part, so that the plurality of infrared heaters can be arranged neatly.

也可以是,在上述的基板加熱裝置中,還包括加熱器單元,所述加熱器單元構成為在一表面上鋪設多個所述紅外線加熱器。 根據該構成,因為具備上述紅外線加熱器,所以能夠提高加熱器單元的溫度分佈的平衡。此外,在能夠個別地控制多個紅外線加熱器的情況下,能夠使一部分的紅外線加熱器的輸出比其他的紅外線加熱器的輸出大,所以能夠對基板進行溫度分佈良好的加熱。例如,在基板的四角的溫度較低的情況下,使配置在與該部分對應的位置的紅外線加熱器的輸出比其他的紅外線加熱器的輸出大,由此僅提高該部分的溫度,能夠提高基板整體的溫度分佈。The above-mentioned substrate heating apparatus may further include a heater unit configured by laying a plurality of the infrared heaters on one surface. According to this configuration, since the above-described infrared heater is provided, the balance of the temperature distribution of the heater unit can be improved. In addition, when a plurality of infrared heaters can be individually controlled, the output of some of the infrared heaters can be made larger than the output of the other infrared heaters, so that the substrate can be heated with a favorable temperature distribution. For example, when the temperature of the four corners of the substrate is low, the output of the infrared heater arranged at the position corresponding to the portion is made larger than the output of the other infrared heaters, thereby increasing the temperature of only this portion, and it is possible to improve the The temperature distribution of the entire substrate.

也可以是,在上述的基板加熱裝置中,所述加熱器單元包括:多個第一紅外線加熱器,在一方向上鋪設配置;多個第二紅外線加熱器,在與所述一方向平行的方向上鋪設配置,所述第二紅外線加熱器以與相鄰的2個所述第一紅外線加熱器的邊界部鄰接的方式,在與所述一方向交叉的方向上與所述第一紅外線加熱器鋪設配置。 根據該構成,因為第一紅外線加熱器的溫度分佈與第二紅外線加熱器的溫度分佈能夠相互地補足,所以能夠更進一步地提高加熱器單元的溫度分佈的平衡。In the above-mentioned substrate heating apparatus, the heater unit may include: a plurality of first infrared heaters, which are laid out in one direction; and a plurality of second infrared heaters, which are arranged in a direction parallel to the one direction. The second infrared heater is arranged to be laid on top of the first infrared heater in a direction intersecting with the one direction so as to be adjacent to the boundary portion of the two adjacent first infrared heaters. Lay configuration. According to this configuration, since the temperature distribution of the first infrared heater and the temperature distribution of the second infrared heater can complement each other, the balance of the temperature distribution of the heater unit can be further improved.

也可以是,在上述的基板加熱裝置中,在俯視狀態下,所述第二紅外線加熱器具有與所述第一紅外線加熱器相同的形狀。 根據該構成,與在俯視狀態下第二紅外線加熱器具有與第一紅外線加熱器不同的形狀的情況相比,能夠更可靠地提高加熱器單元的溫度分佈的平衡。此外,即便改變基板尺寸,也能夠通過改變紅外線加熱器的個數,等間隔地配置紅外線加熱器,而對基板進行溫度分佈良好的加熱。然而,在紅外線加熱器為單純的直管的情況下,若基板尺寸變大,則需要使直管的長度伸長,因此存在難以容許紅外線加熱器的熱膨脹的可能性。但是,根據該構成,即便基板尺寸變大,紅外線加熱器的尺寸也不會改變,因此能夠容易地容許紅外線加熱器的熱膨脹。In the above-mentioned substrate heating apparatus, the second infrared heater may have the same shape as the first infrared heater in a plan view. According to this configuration, the balance of the temperature distribution of the heater unit can be improved more reliably than when the second infrared heater has a shape different from that of the first infrared heater in a plan view. In addition, even if the size of the substrate is changed, by changing the number of infrared heaters and arranging the infrared heaters at equal intervals, the substrate can be heated with a favorable temperature distribution. However, when the infrared heater is a simple straight tube, if the size of the substrate increases, the length of the straight tube needs to be extended, so that it may be difficult to tolerate thermal expansion of the infrared heater. However, according to this configuration, even if the size of the substrate increases, the size of the infrared heater does not change, so that the thermal expansion of the infrared heater can be easily tolerated.

也可以是,在上述的基板加熱裝置中,在俯視狀態下,所述第二紅外線加熱器具有使所述第一紅外線加熱器旋轉90度後的形狀。 根據該構成,因為能夠利用第一紅外線加熱器與第二紅外線加熱器來相互地補足由紅外線加熱器的形狀引起的溫度分佈,所以能夠更進一步地提高加熱器單元的溫度分佈的平衡。In the above-mentioned substrate heating apparatus, the second infrared heater may have a shape obtained by rotating the first infrared heater by 90 degrees in a plan view. According to this configuration, since the temperature distribution caused by the shape of the infrared heater can be mutually complemented by the first infrared heater and the second infrared heater, the balance of the temperature distribution of the heater unit can be further improved.

也可以是,在上述的基板加熱裝置中,還包括加熱部,所述加熱部隔著所述基板配置在與所述紅外線加熱器相反的一側,並且能夠加熱所述基板。 根據該構成,因為加熱部的加熱與紅外線加熱器的加熱相輔相成,能夠更有效地加熱基板。The above-mentioned substrate heating apparatus may further include a heating unit which is arranged on the opposite side of the infrared heater across the substrate and capable of heating the substrate. According to this structure, since the heating of the heating part and the heating of the infrared heater are complemented, the board|substrate can be heated more efficiently.

也可以是,在上述的基板加熱裝置中,還包括能夠容納所述基板、所述加熱部以及所述紅外線加熱器的腔室。 根據該構成,因為能夠在腔室內管理基板的加熱溫度,所以能夠有效地加熱基板。The above-mentioned substrate heating apparatus may further include a chamber capable of accommodating the substrate, the heating unit, and the infrared heater. According to this configuration, since the heating temperature of the substrate can be managed in the chamber, the substrate can be efficiently heated.

也可以是,在上述的基板加熱裝置中,所述基板、所述加熱部以及所述紅外線加熱器被共用的所述腔室容納。 根據該構成,能夠在共用的腔室內一併地進行加熱部對基板的加熱處理與紅外線加熱器對基板的加熱處理。即,不必像加熱部以及紅外線加熱器被容納於相互不同的腔室的情況那樣地,需要用於使基板在不同的2個腔室之間輸送的時間。因此,能夠更高效地進行基板的加熱處理。此外,與具備不同的2個腔室的情況相比較,能夠使裝置整體小型化。In the above-mentioned substrate heating apparatus, the substrate, the heating unit, and the infrared heater may be accommodated in the common chamber. According to this configuration, the heating process of the substrate by the heating unit and the heating process of the substrate by the infrared heater can be collectively performed in the common chamber. That is, as in the case where the heating unit and the infrared heater are accommodated in different chambers, time for transferring the substrate between the two different chambers is not necessary.

The position adjustment unit 7 can adjust the relative positions of the heating unit 5 and the infrared heater 6 and the substrate 10 . The position adjustment unit 7 includes a moving unit 7a and a driving unit 7b. The moving part 7a is a columnar member extending up and down (Z direction). The upper end of the moving part 7 a is fixed to the lower surface of the heating part 5 . The drive part 7b can move the moving part 7a up and down.

Specifically, when the substrate 10 is placed on the upper surface of the heating unit 5 , the moving unit 7 a can move the substrate 10 up and down by the driving of the driving unit 7 b (see FIGS. 5 and 6 ).

驅動部7b配置在腔室2的外部。因此,即便假設隨著驅動部7b的驅動而產生微塵,通過使腔室2內為密閉空間,也能夠避免微塵向腔室2內的入侵。The drive unit 7b is arranged outside the chamber 2 . Therefore, even if it is assumed that fine dust is generated in accordance with the driving of the drive unit 7b, the intrusion of the fine dust into the chamber 2 can be avoided by making the inside of the chamber 2 a closed space.

<輸送部> 輸送部8在腔室2內被配置在加熱部5與紅外線加熱器6之間。輸送部8能夠輸送基板10。在輸送部8形成有能夠使移動部7a通過的通過部8h。輸送部8具備沿著基板10的輸送方向即X方向配置的多個輸送輥8a。<Conveying Department> The conveying unit 8 is arranged between the heating unit 5 and the infrared heater 6 in the chamber 2 . The transport unit 8 can transport the substrate 10 . The conveyance part 8 is formed with a passage part 8h through which the moving part 7a can pass. The conveyance part 8 is provided with the some conveyance roller 8a arrange|positioned along the X direction which is the conveyance direction of the board|substrate 10.

多個輸送輥8a遠離地配置在周壁23的+Y方向側與-Y方向側。即,通過部8h是周壁23的+Y方向側的輸送輥8a與周壁23的-Y方向側的輸送輥8a之間的空間。The plurality of conveyance rollers 8a are arranged on the +Y direction side and the −Y direction side of the peripheral wall 23 so as to be spaced apart. That is, the passage portion 8h is a space between the conveyance roller 8a on the +Y direction side of the peripheral wall 23 and the conveyance roller 8a on the −Y direction side of the peripheral wall 23 .

例如,在周壁23的+Y方向側以及-Y方向側,沿著X方向分別地配置有在Y方向上延伸的多個軸(未圖示)。各輸送輥8a由驅動機構(未圖示)驅動而繞各軸旋轉。For example, on the +Y direction side and the −Y direction side of the peripheral wall 23 , a plurality of shafts (not shown) extending in the Y direction are respectively arranged along the X direction. Each conveyance roller 8a is driven by a drive mechanism (not shown) to rotate about each axis.

圖3是用於說明輸送輥8a、基板10以及加熱部5的配置關係的圖。圖3相當於基板加熱裝置1的俯視圖。為了方便,在圖3中以雙點虛線示出腔室2。 在圖3中,附圖標記L1是周壁23的+Y方向側的輸送輥8a與周壁23的-Y方向側的輸送輥8a遠離(相距)的間隔(以下稱為“輥遠離間隔”)。此外,附圖標記L2是基板10的Y方向的長度(以下稱為“基板長度”)。此外,附圖標記L3是加熱部5的Y方向的長度(以下稱為“加熱部長度”)。3 : is a figure for demonstrating the arrangement|positioning relationship of the conveyance roller 8a, the board|substrate 10, and the heating part 5. FIG. FIG. 3 corresponds to a plan view of the substrate heating apparatus 1 . For convenience, the chamber 2 is shown in FIG. 3 with a double-dotted dashed line. In FIG. 3 , the reference numeral L1 is an interval (hereinafter referred to as “roller distance interval”) at which the conveying roller 8a on the +Y direction side of the peripheral wall 23 and the conveying roller 8a on the −Y direction side of the peripheral wall 23 are separated from each other. In addition, the reference numeral L2 is the length in the Y direction of the substrate 10 (hereinafter referred to as “substrate length”). In addition, reference numeral L3 is the length of the Y direction of the heating part 5 (henceforth "heating part length").

如圖3所示,輥遠離間隔L1比基板長度L2小,並且比加熱部長度L3大(L3<L1<L2)。輥遠離間隔L1比加熱部長度L3大,由此移動部7a能夠與加熱部5一起通過通過部8h(參照圖5以及圖6)。As shown in FIG. 3 , the roller separation interval L1 is smaller than the substrate length L2 and larger than the heating portion length L3 ( L3 < L1 < L2 ). The roller distance interval L1 is larger than the heating portion length L3, whereby the moving portion 7a can pass through the passage portion 8h together with the heating portion 5 (see FIGS. 5 and 6 ).

In addition, although only one temperature detection part 9 is shown in FIG. 1, the number of the temperature detection part 9 is not limited to one, and may be more than one. For example, it is preferable to arrange the plurality of temperature detection units 9 at the center and the four corners of the top plate 21 .

<回收部> 回收部11連接於減壓部3(真空泵13)的管線。回收部11能夠回收從塗布於基板10的聚醯亞胺形成用液揮發的溶劑。<Recycling Department> The recovery unit 11 is connected to the line of the decompression unit 3 (vacuum pump 13 ). The recovery unit 11 can recover the solvent volatilized from the polyimide-forming liquid applied to the substrate 10 .

In the present embodiment, the substrate 10 is heated using the above-described substrate heating apparatus 1 . The operations performed by the components of the substrate heating apparatus 1 are controlled by the control unit 15 .

本實施方式的基板加熱方法包括:減壓工程、第一加熱工程以及第二加熱工程。 在減壓工程中,對塗布了聚醯亞胺形成用液的基板10的容納空間的氛圍進行減壓。 如圖4所示,在減壓工程中,基板10被配置於輸送輥8a。此外,在減壓工程中,加熱部5位於底板22附近。在減壓工程中,加熱部5以及基板10以加熱部5的熱量不會傳遞至基板10的程度遠離。在減壓工程中,接通加熱部5的電源。加熱部5的溫度例如是250℃左右。另一方面,在減壓工程中,斷開紅外線加熱器6的電源。The substrate heating method of the present embodiment includes a decompression process, a first heating process, and a second heating process. In the decompression process, the atmosphere of the accommodation space of the substrate 10 to which the liquid for forming polyimide is applied is decompressed. As shown in FIG. 4, in the decompression process, the board|substrate 10 is arrange|positioned on the conveyance roller 8a. In addition, in the decompression process, the heating part 5 is located in the vicinity of the bottom plate 22 . In the decompression process, the heating unit 5 and the substrate 10 are separated to such an extent that the heat of the heating unit 5 is not transferred to the substrate 10 . In the decompression process, the power supply of the heating unit 5 is turned on. The temperature of the heating unit 5 is, for example, about 250°C. On the other hand, in the decompression process, the power supply of the infrared heater 6 is turned off.

在減壓工程中,使基板10的容納空間的氛圍從大氣壓減壓到500Pa以下。例如,在減壓工程中使腔室內壓力逐漸從大氣壓下降到20Pa。In the decompression process, the atmosphere of the accommodation space of the substrate 10 is decompressed from atmospheric pressure to 500 Pa or less. For example, in the decompression process, the pressure in the chamber is gradually lowered from atmospheric pressure to 20 Pa.

在減壓工程中,使腔室2的內部氛圍的氧濃度盡可能地低。例如,在減壓工程中,使腔室2內的真空度為20Pa以下。由此,能夠使腔室2內的氧氣濃度為100ppm以下。In the decompression process, the oxygen concentration of the inner atmosphere of the chamber 2 is made as low as possible. For example, in the decompression process, the degree of vacuum in the chamber 2 is set to 20 Pa or less. Thereby, the oxygen concentration in the chamber 2 can be made 100 ppm or less.

在減壓工程之後,在第一加熱工程中,以第一溫度加熱基板10。 如圖5所示,在第一加熱工程中,使加熱部5移動至上方,使基板10載置在加熱部5的上表面。由此,通過使加熱部5抵接基板10的第二表面10b,加熱部5的熱量直接傳遞至基板10。在第一加熱工程中,加熱部5的溫度例如維持在250℃。因此,基板溫度能夠上升到250℃。另一方面,在第一加熱工程中,紅外線加熱器6的電源一直處於斷開狀態。After the decompression process, in the first heating process, the substrate 10 is heated at the first temperature. As shown in FIG. 5 , in the first heating step, the heating unit 5 is moved upward, and the substrate 10 is placed on the upper surface of the heating unit 5 . Thereby, the heat of the heating part 5 is directly transferred to the board|substrate 10 by making the heating part 5 contact|abut the 2nd surface 10b of the board|substrate 10. In the first heating process, the temperature of the heating unit 5 is maintained at, for example, 250°C. Therefore, the substrate temperature can be raised to 250°C. On the other hand, in the 1st heating process, the power supply of the infrared heater 6 is always in the OFF state.

另外,在第一加熱工程中,加熱部5位於通過部8h(參照圖1)內。為了方便,在圖5中,以雙點虛線示出移動前(減壓工程時的位置)的加熱部5,以實線示出移動後(第一加熱工程時的位置)的加熱部5。In addition, in the 1st heating process, the heating part 5 is located in the passage part 8h (refer FIG. 1). For convenience, in FIG. 5 , the heating unit 5 before the movement (the position during the decompression process) is shown by the double-dotted line, and the heating unit 5 after the movement (the position during the first heating process) is shown by the solid line.

在第一加熱工程中,在保持減壓工程的氛圍的狀態下,基板溫度為150℃到300℃的範圍,將基板10加熱到使得塗布於基板10的聚醯亞胺形成用液揮發或者醯亞胺化。例如,在第一加熱工程中,對基板10進行加熱的時間為10min以下。具體而言,在第一加熱工程中,將對基板10進行加熱的時間設為3min。例如,在第一加熱工程中,使基板溫度從25℃緩慢地上升到250℃。In the first heating step, the substrate 10 is heated to a temperature in the range of 150° C. to 300° C. while maintaining the atmosphere of the depressurization step until the polyimide-forming liquid applied to the substrate 10 is volatilized or the polyimide is imidization. For example, in the first heating process, the time for heating the substrate 10 is 10 min or less. Specifically, in the first heating process, the time for heating the substrate 10 was set to 3 min. For example, in the first heating step, the substrate temperature is gradually raised from 25°C to 250°C.

第一加熱工程之後,在第二加熱工程中,以比第一溫度高的第二溫度對基板10進行加熱。在第二加熱工程中,使用紅外線加熱器6加熱基板10,所述紅外線加熱器6與第一加熱工程中使用的加熱部5分別獨立地設置。另外,第二加熱工程相當於申請專利範圍所述的加熱工程。After the first heating process, in the second heating process, the substrate 10 is heated at a second temperature higher than the first temperature. In the second heating process, the substrate 10 is heated using the infrared heaters 6 provided separately from the heating units 5 used in the first heating process. In addition, the second heating process corresponds to the heating process described in the scope of the patent application.

如圖6所示,在第二加熱工程中,使加熱部5移動到比第一加熱工程時的位置的更上方,使基板10接近紅外線加熱器6。例如,在第二加熱工程中,加熱部5的溫度維持在250℃。此外,在第二加熱工程中,接通紅外線加熱器6的電源。例如,紅外線加熱器6能夠以450℃對基板10進行加熱。因此,基板溫度能夠上升到450℃。在第二加熱工程中,基板10比在第一加熱工程時更接近紅外線加熱器6,因此紅外線加熱器6的熱量被充分地傳遞至基板10。As shown in FIG. 6 , in the second heating step, the heating unit 5 is moved to a position higher than the position in the first heating step, and the substrate 10 is brought close to the infrared heater 6 . For example, in the second heating process, the temperature of the heating unit 5 is maintained at 250°C. In addition, in the second heating process, the power of the infrared heater 6 is turned on. For example, the infrared heater 6 can heat the substrate 10 at 450°C. Therefore, the substrate temperature can be raised to 450°C. In the second heating process, since the substrate 10 is closer to the infrared heater 6 than in the first heating process, the heat of the infrared heater 6 is sufficiently transferred to the substrate 10 .

另外,在第二工程中,加熱部5位於輸送輥8a(圖1所示的通過部8h)的上方並且紅外線加熱器6的下方。為了方便,在圖6中,以雙點虛線示出移動前(第一加熱工程時的位置)的加熱部5,以實線示出移動後(第二加熱工程時的位置)加熱部5。In addition, in the 2nd process, the heating part 5 is located above the conveyance roller 8a (passage part 8h shown in FIG. 1 ) and below the infrared heater 6 . For convenience, in FIG. 6 , the heating unit 5 before the movement (the position during the first heating process) is shown by a double-dotted line, and the heating unit 5 after the movement (the position during the second heating process) is shown by a solid line.

在第二加熱工程中,在保持減壓工程的氛圍的狀態下,對基板10進行加熱,使基板溫度從第一加熱工程的溫度變為600℃以下。例如,在第二加熱工程中,使基板溫度從250℃急劇地上升到450℃。此外,在第二加熱工程中,使腔室內壓力維持在20Pa以下。In the second heating step, the substrate 10 is heated while maintaining the atmosphere of the decompression step so that the substrate temperature is 600° C. or lower from the temperature of the first heating step. For example, in the second heating process, the substrate temperature is rapidly increased from 250°C to 450°C. In addition, in the second heating process, the pressure in the chamber was maintained at 20 Pa or less.

第二加熱工程包括使基板10冷卻的冷卻工程。例如,在冷卻工程中,在保持減壓工程的氛圍或者低氧氛圍的狀態下對基板10進行冷卻,使基板溫度從第二加熱工程的溫度變為能夠對基板10進行輸送的溫度。在冷卻工程中,斷開紅外線加熱器6的電源。The second heating process includes a cooling process of cooling the substrate 10 . For example, in the cooling process, the substrate 10 is cooled while maintaining the atmosphere of the decompression process or the low-oxygen atmosphere, and the substrate temperature is changed from the temperature in the second heating process to a temperature at which the substrate 10 can be transported. In the cooling process, the power of the infrared heater 6 is turned off.

通過經過以上的工程,進行塗布於基板10的聚醯亞胺形成用液的揮發或者醯亞胺化,並且進行塗布於基板10的聚醯亞胺形成用液的醯亞胺化時的分子鏈的再排列,能夠形成聚醯亞胺膜。Through the above process, the volatilization or imidization of the polyimide-forming liquid applied to the substrate 10 is performed, and the molecular chain at the time of imidization of the polyimide-forming liquid applied to the substrate 10 is carried out. The rearrangement can form a polyimide film.

如上所述,根據本實施方式,紅外線加熱器6包括配置為從外側覆蓋彎曲部31a~31h的至少一部分的蓋部32、33,所以能夠避免彎曲部31a~31h的露出,從而能夠抑制彎曲部31a~31h與其他部分相比發生降溫。即,因為通過蓋部32、33能夠從外側加熱彎曲部31a~31h的至少一部分,所以能夠抑制彎曲部31a~31h與其他部分產生溫度差。因此,能夠提高紅外線加熱器6的溫度分佈的平衡。As described above, according to the present embodiment, since the infrared heater 6 includes the cover parts 32 and 33 arranged to cover at least a part of the curved parts 31a to 31h from the outside, exposure of the curved parts 31a to 31h can be avoided, and the curved parts can be suppressed. 31a ~ 31h, compared with other parts, the temperature dropped. That is, since at least a part of the curved parts 31a to 31h can be heated from the outside by the cover parts 32 and 33, the temperature difference between the curved parts 31a to 31h and other parts can be suppressed. Therefore, the balance of the temperature distribution of the infrared heater 6 can be improved.

此外,蓋部32、33以從外側覆蓋多個彎曲部31a~31h的方式在第二方向V2上直線狀地延伸,由此能夠一併地避免多個彎曲部31a~31h露出,因此能夠一併地抑制多個彎曲部31a~31h與其他部分相比發生降溫。即,因為通過蓋部32、33,能夠從外側一併地加熱多個彎曲部31a~31h,所以能夠抑制多個彎曲部31a~31h與其他部分產生溫度差。因此,能夠高效地提高紅外線加熱器6的溫度分佈的平衡。此外,紅外線加熱器6還包括在第一方向V1上具有長邊、並且在與第一方向V1交叉的第二方向V2上並列配置的多個直部30a~30i,由此通過多個直部30a~30i相互地相鄰,能夠提高相互的發熱溫度,因此能夠在較高溫度下提高紅外線加熱器6的溫度分佈的平衡。In addition, the cover parts 32 and 33 linearly extend in the second direction V2 so as to cover the plurality of curved parts 31a to 31h from the outside, and thus the plurality of curved parts 31a to 31h can be prevented from being exposed at the same time. In parallel, the plurality of curved portions 31a to 31h are restrained from being lowered in temperature compared with other portions. That is, since the plurality of curved portions 31a to 31h can be collectively heated from the outside by the cover portions 32 and 33, the temperature difference between the plurality of curved portions 31a to 31h and other portions can be suppressed. Therefore, the balance of the temperature distribution of the infrared heater 6 can be efficiently improved. In addition, the infrared heater 6 further includes a plurality of straight portions 30a to 30i which have long sides in the first direction V1 and are arranged in parallel in the second direction V2 intersecting with the first direction V1, thereby passing through the plurality of straight portions 30a to 30i are adjacent to each other, and since the mutual heat generation temperature can be increased, the balance of the temperature distribution of the infrared heater 6 can be improved at a relatively high temperature.

然而,若第一導入部34與第二導入部35過於接近,則存在該部分的溫度與其他部分的溫度相比降溫的傾向。但是,根據本實施方式,通過將第一導入部34以及第二導入部35的兩者設置在蓋部32、33的端部,因為第一導入部34與第二導入部35一定程度地遠離,所以能夠抑制紅外線加熱器6局部地降溫。因此,能夠提高紅外線加熱器6的溫度分佈的平衡。此外,根據本實施方式,通過使第一導入部34與第二導入部35的距離(紅外線加熱器6的外部形狀的一邊的長度)為225mm左右,即便腔室2的頂板21熱膨脹或者熱收縮,也能夠容許所述膨脹或者收縮。However, when the first introduction portion 34 and the second introduction portion 35 are too close, the temperature of this portion tends to drop compared to the temperature of other portions. However, according to the present embodiment, by providing both the first introduction part 34 and the second introduction part 35 at the ends of the cover parts 32 and 33 , the first introduction part 34 and the second introduction part 35 are separated to some extent. , the temperature of the infrared heater 6 can be suppressed from being locally lowered. Therefore, the balance of the temperature distribution of the infrared heater 6 can be improved. Furthermore, according to the present embodiment, by setting the distance between the first introduction part 34 and the second introduction part 35 (the length of one side of the outer shape of the infrared heater 6 ) to be about 225 mm, even if the top plate 21 of the chamber 2 is thermally expanded or contracted , can also tolerate the expansion or contraction.

此外,在俯視狀態下,紅外線加熱器6的外部形狀呈矩形形狀,第一導入部34配置在紅外線加熱器6的一邊的一側,第二導入部35配置在所述一邊的另一側,從而起到以下的效果。因為紅外線加熱器6中從第二導入部35到彎曲部31h的部分成為在2個部位彎折的U字管狀(即沿著除了紅外線加熱器6的所述一邊以外的三邊的形狀),所以與直管狀以及L字管狀的情況相比較,能夠提高紅外線加熱器6的柔軟性。因此,即便紅外線加熱器6的所述一邊熱膨脹或者熱收縮,由於紅外線加熱器6的柔軟性,也能夠容許所述一邊的膨脹或者收縮。In addition, in a plan view, the outer shape of the infrared heater 6 is a rectangular shape, the first introduction part 34 is arranged on one side of one side of the infrared heater 6, and the second introduction part 35 is arranged on the other side of the one side, Thus, the following effects are achieved. Since the portion of the infrared heater 6 from the second introduction portion 35 to the curved portion 31h has a U-shaped tubular shape (ie, a shape along three sides other than the one side of the infrared heater 6) bent at two places, Therefore, the flexibility of the infrared heater 6 can be improved as compared with the case of the straight tube shape and the L-shaped tube shape. Therefore, even if the one side of the infrared heater 6 thermally expands or contracts, the expansion or contraction of the one side can be tolerated due to the flexibility of the infrared heater 6 .

此外,在俯視狀態下,第一導入部34以及第二導入部35的兩者都進入紅外線加熱器6的外部形狀內,由此在配置紅外線加熱器6時,因為能夠避免第一導入部34以及第二導入部35成為妨礙,所以能夠提高佈局的自由度。例如,在一表面上鋪設多個紅外線加熱器6時,能夠避免相鄰的2個紅外線加熱器6在第一導入部34以及第二導入部35處發生干涉,因此能夠整齊地鋪設多個紅外線加熱器6。In addition, in a plan view, both the first introduction part 34 and the second introduction part 35 enter into the outer shape of the infrared heater 6 , so that the first introduction part 34 can be avoided when the infrared heater 6 is arranged. And the second introduction portion 35 becomes an obstacle, so the degree of freedom of layout can be improved. For example, when a plurality of infrared heaters 6 are laid on one surface, interference between two adjacent infrared heaters 6 at the first introduction portion 34 and the second introduction portion 35 can be avoided, so that a plurality of infrared heaters can be laid neatly Heater 6.

此外,還包括加熱部5,隔著基板10配置在與紅外線加熱器6相反的一側,並且能夠加熱基板10,由此因為加熱部5的加熱與紅外線加熱器6的加熱相輔相成,能夠更有效地加熱基板10。In addition, the heating unit 5 is provided on the opposite side of the infrared heater 6 with the substrate 10 interposed therebetween, and the substrate 10 can be heated. Therefore, the heating by the heating unit 5 and the heating by the infrared heater 6 can be supplemented, so that the heating can be more efficient. The substrate 10 is heated.

此外,還包括能夠容納基板10、加熱部5以及紅外線加熱器6的腔室2,由此能夠在腔室2內管理基板10的加熱溫度,因此能夠有效地加熱基板10。In addition, the chamber 2 capable of accommodating the substrate 10 , the heating unit 5 , and the infrared heater 6 is included, whereby the heating temperature of the substrate 10 can be managed in the chamber 2 , so that the substrate 10 can be efficiently heated.

此外,基板10、加熱部5以及紅外線加熱器6被共用的腔室2容納,由此能夠在共用的腔室2內一併地進行加熱部5對基板10的加熱處理與紅外線加熱器6對基板10的加熱處理。即,不必像加熱部5以及紅外線加熱器6被容納於相互不同的腔室2的情況那樣地,需要用於使基板10在不同的2個腔室2之間輸送的時間。因此,能夠更高效地進行基板10的加熱處理。此外,與具備不同的2個腔室2的情況相比,能夠使裝置整體小型化。In addition, since the substrate 10 , the heating unit 5 and the infrared heater 6 are accommodated in the common chamber 2 , the heating process of the substrate 10 by the heating unit 5 and the pairing of the infrared heater 6 can be performed together in the common chamber 2 . Heat treatment of the substrate 10 . That is, as in the case where the heating unit 5 and the infrared heater 6 are accommodated in different chambers 2, time for transferring the substrate 10 between the two different chambers 2 is not necessary. Therefore, the heat treatment of the substrate 10 can be performed more efficiently. Moreover, compared with the case where two different chambers 2 are provided, the overall size of the apparatus can be reduced.

此外,聚醯亞胺形成用液僅被塗布在基板10的第一表面10a,加熱部5被配置於基板10的第一表面10a的相反側即第二表面10b的一側,由此起到以下的效果。因為從加熱部5產生的熱量從基板10的第二表面10b的一側朝向第一表面10a的一側傳遞,所以能夠有效地加熱基板10。此外,在利用加熱部5加熱基板10的期間,能夠高效地進行被塗布於基板10的聚醯亞胺形成用液的揮發或者醯亞胺化(例如成膜中的排氣)。In addition, the liquid for forming polyimide is applied only on the first surface 10a of the substrate 10, and the heating unit 5 is arranged on the opposite side of the first surface 10a of the substrate 10, that is, on the side of the second surface 10b, thereby achieving The following effects. Since the heat generated from the heating portion 5 is transferred from the side of the second surface 10b of the substrate 10 toward the side of the first surface 10a, the substrate 10 can be efficiently heated. In addition, while the substrate 10 is heated by the heating unit 5 , volatilization or imidization of the polyimide-forming liquid applied to the substrate 10 (eg, exhaust gas during film formation) can be efficiently performed.

此外,加熱部5以及紅外線加熱器6都能夠階段性地加熱基板10,由此起到以下的效果。與加熱部5以及紅外線加熱器6僅能以恆定的溫度加熱基板10的情況相比較,能夠高效地加熱基板10以適合塗布於基板10的聚醯亞胺形成用液的成膜條件。因此,使塗布於基板10的聚醯亞胺形成用液階段性地乾燥,能夠良好地固化。In addition, both the heating unit 5 and the infrared heater 6 can heat the substrate 10 in steps, and thus the following effects are obtained. Compared with the case where the heating unit 5 and the infrared heater 6 can only heat the substrate 10 at a constant temperature, the substrate 10 can be efficiently heated to suit the film-forming conditions of the polyimide-forming liquid applied to the substrate 10 . Therefore, the liquid for forming polyimide applied to the substrate 10 can be dried stepwise and cured well.

此外,還包括位置調整部7,能夠調整加熱部5以及紅外線加熱器6與基板10的相對位置,由此,與不具備位置調整部7的情況相比較,容易調整基板10的加熱溫度。例如,能夠在要使基板10的加熱溫度變高的情況下,使加熱部5以及紅外線加熱器6接近基板10,能夠在要使基板10的加熱溫度變低的情況下,使加熱部5以及紅外線加熱器6遠離基板10。因此,容易階段性地加熱基板10。In addition, the position adjusting unit 7 is included to adjust the relative positions of the heating unit 5 and the infrared heater 6 and the substrate 10 , thereby making it easier to adjust the heating temperature of the substrate 10 than when the position adjusting unit 7 is not provided. For example, when the heating temperature of the substrate 10 is to be increased, the heating unit 5 and the infrared heater 6 can be brought close to the substrate 10, and when the heating temperature of the substrate 10 is to be decreased, the heating unit 5 and the infrared heater 6 can be brought close to the substrate 10. The infrared heater 6 is far from the substrate 10 . Therefore, it is easy to heat the substrate 10 in steps.

此外,位置調整部7包括能夠使基板10在加熱部5與紅外線加熱器6之間移動的移動部7a,從而通過使基板10在加熱部5與紅外線加熱器6之間移動,在將加熱部5以及紅外線加熱器6中的至少一方配置在固定位置的狀態下,能夠調整基板10的加熱溫度。因此,無需另外設置能夠使加熱部5以及紅外線加熱器6的至少一方移動的裝置,因此能夠以簡單的構成調整基板10的加熱溫度。In addition, the position adjustment unit 7 includes a moving unit 7 a capable of moving the substrate 10 between the heating unit 5 and the infrared heater 6 . By moving the substrate 10 between the heating unit 5 and the infrared heater 6 , the heating unit is moved The heating temperature of the substrate 10 can be adjusted in a state where at least one of the 5 and the infrared heater 6 is arranged at a fixed position. Therefore, there is no need to separately provide a device capable of moving at least one of the heating unit 5 and the infrared heater 6 , so that the heating temperature of the substrate 10 can be adjusted with a simple configuration.

此外,在加熱部5與紅外線加熱器6之間,設置有能夠輸送基板10的輸送部8,在輸送部8中形成有能夠使移動部7a通過的通過部8h,從而起到以下的效果。在使基板10在加熱部5與紅外線加熱器6之間移動的情況下,因為能夠使基板10通過通過部8h,所以無需使基板10繞過輸送部8而移動。因此,無需另外設置用於使基板10繞過輸送部8而移動的裝置,能夠以簡單的構成順暢地進行基板10的移動。In addition, between the heating unit 5 and the infrared heater 6 , a conveying unit 8 capable of conveying the substrate 10 is provided, and the conveying unit 8 is formed with a passage portion 8 h through which the moving portion 7 a can pass, thereby exhibiting the following effects. When moving the board|substrate 10 between the heating part 5 and the infrared heater 6, since the board|substrate 10 can pass the passing part 8h, it is not necessary to move the board|substrate 10 bypassing the conveyance part 8. Therefore, there is no need to separately provide a device for moving the substrate 10 around the conveyance unit 8 , and the substrate 10 can be smoothly moved with a simple configuration.

此外,加熱部5是電熱板,由此能夠在基板10的面內使基板10的加熱溫度均勻化,因此能夠提高膜特性。例如,在使電熱板的一表面與基板10的第二表面10b抵接的狀態下加熱基板10,由此能夠提高基板10的加熱溫度的面內均勻性。In addition, since the heating unit 5 is a hot plate, the heating temperature of the substrate 10 can be made uniform within the surface of the substrate 10 , so that the film properties can be improved. For example, the in-plane uniformity of the heating temperature of the substrate 10 can be improved by heating the substrate 10 in a state in which one surface of the hot plate is in contact with the second surface 10b of the substrate 10 .

此外,還包括能夠檢測基板10的溫度的溫度檢測部9,由此能夠即時地掌握基板10溫度。例如,通過基於溫度檢測部9的的檢測結果對基板10進行加熱,能夠抑制基板10溫度偏離目標值。Moreover, the temperature detection part 9 which can detect the temperature of the board|substrate 10 is included, and the temperature of the board|substrate 10 can be grasped|ascertained immediately. For example, by heating the substrate 10 based on the detection result of the temperature detection unit 9 , it is possible to suppress the temperature of the substrate 10 from deviating from the target value.

此外,還包括回收部11,能夠回收從塗布於基板10的聚醯亞胺形成用液揮發的溶劑,由此能夠防止從聚醯亞胺形成用液揮發的溶劑向工廠側排出。此外,在將回收部11連接於減壓部3(真空泵13)的管線的情況下,能夠防止從聚醯亞胺形成用液揮發的溶劑再次液化而逆流至真空泵13內。進而,從聚醯亞胺形成用液揮發的溶劑能夠作為清洗液再利用。例如,清洗液能夠用於噴嘴前端的清洗、附著於刮取構件的液體的清洗等,所述刮取構件對附著在噴嘴上的液體進行刮取。In addition, the recovery unit 11 is included to recover the solvent volatilized from the polyimide-forming liquid applied to the substrate 10, thereby preventing the solvent volatilized from the polyimide-forming liquid from being discharged to the factory. Further, when the recovery unit 11 is connected to the line of the decompression unit 3 (vacuum pump 13 ), the solvent volatilized from the polyimide-forming liquid can be prevented from being liquefied again and flowing back into the vacuum pump 13 . Furthermore, the solvent volatilized from the liquid for forming polyimide can be reused as a cleaning liquid. For example, the cleaning liquid can be used for cleaning the tip of the nozzle, cleaning the liquid adhering to the scraping member that scrapes the liquid adhering to the nozzle, and the like.

此外,紅外線加熱器6被配置在基板10的第一表面10a的一側,由此從紅外線加熱器6產生的熱量從基板10的第一表面10a的一側傳遞至第二表面10b的一側,由此加熱部5的加熱與紅外線加熱器6的加熱相輔相成,能夠更有效地加熱基板10。Further, the infrared heater 6 is arranged on the side of the first surface 10 a of the substrate 10 , whereby the heat generated from the infrared heater 6 is transferred from the side of the first surface 10 a to the side of the second surface 10 b of the substrate 10 Accordingly, the heating of the heating unit 5 and the heating of the infrared heater 6 are complemented, and the substrate 10 can be heated more efficiently.

此外,通過紅外線加熱器6的紅外線加熱,能夠在短時間內將基板10升溫到第二溫度。此外,因為能夠在使紅外線加熱器6與基板10遠離的狀態下,對基板10進行加熱(所謂的非接觸加熱),所以能夠保持基板10的清潔(所謂的清潔加熱)。In addition, the temperature of the substrate 10 can be raised to the second temperature in a short time by the infrared heating of the infrared heater 6 . In addition, since the substrate 10 can be heated with the infrared heater 6 separated from the substrate 10 (so-called non-contact heating), the substrate 10 can be kept clean (so-called clean heating).

此外,因為紅外線加熱器的峰值波長範圍是1.5μm以上並且4μm以下的範圍,而1.5μm以上並且4μm以下的範圍的波長與玻璃以及水等的吸收波長一致,因此能夠更有效地加熱基板10以及塗布於基板10的聚醯亞胺形成用液。In addition, since the peak wavelength range of the infrared heater is in the range of 1.5 μm or more and 4 μm or less, and the wavelength in the range of 1.5 μm or more and 4 μm or less corresponds to the absorption wavelength of glass, water, etc., the substrate 10 and the substrate 10 can be heated more efficiently. The liquid for forming polyimide applied to the substrate 10 .

此外,還包括能夠擺動基板10的擺動部12,由此能夠一邊擺動基板10,一邊加熱基板10,因此能夠提高基板10的溫度均勻性。In addition, by including the swing portion 12 capable of swinging the substrate 10 , the substrate 10 can be heated while swinging the substrate 10 , so that the temperature uniformity of the substrate 10 can be improved.

(第一變形例) 接著,使用圖7對第一實施方式的第一變形例進行說明。 圖7是示出第一實施方式的紅外線加熱器的第一變形例的俯視圖。 在第一變形例中,相對於第一實施方式,紅外線加熱器的形狀特別地不同。在圖7中,對與第一實施方式相同的構成賦予相同的附圖標記,省略其詳細說明。(first modification) Next, a first modification of the first embodiment will be described with reference to FIG. 7 . 7 is a plan view showing a first modification of the infrared heater according to the first embodiment. In the first modification, the shape of the infrared heater is particularly different from that of the first embodiment. In FIG. 7 , the same reference numerals are assigned to the same components as those of the first embodiment, and detailed descriptions thereof will be omitted.

<紅外線加熱器> 如圖7所示,本變形例的紅外線加熱器6A的外部形狀的一邊的長度以及全長比第一實施方式的紅外線加熱器6(參照圖2)的長度短。例如,紅外線加熱器6A的外部形狀的一邊的長度為210mm左右。例如,紅外線加熱器6A的全長為1890mm左右。<Infrared heater> As shown in FIG. 7 , the length of one side and the overall length of the outer shape of the infrared heater 6A of the present modification are shorter than the length of the infrared heater 6 (see FIG. 2 ) of the first embodiment. For example, the length of one side of the outer shape of the infrared heater 6A is about 210 mm. For example, the overall length of the infrared heater 6A is about 1890 mm.

直部30a~30g在第二方向V2上並列配置有多個(例如在本變形例中為7個)。本變形例的相鄰的2個直部30a~30g之間的間隔S1比第一實施方式的相鄰的2個直部30a~30i之間的間隔S1大。例如,本變形例的相鄰的2個直部30a~30g之間的間隔S1為30mm左右。The straight portions 30 a to 30 g are arranged in parallel in the second direction V2 (for example, seven in this modification). The interval S1 between the two adjacent straight portions 30a to 30g in this modification is larger than the interval S1 between the two adjacent straight portions 30a to 30i in the first embodiment. For example, the interval S1 between the two adjacent straight portions 30a to 30g in this modification is about 30 mm.

蓋部32、33以從外側覆蓋多個(例如在本變形例中為6個)彎曲部31a~31f的方式在第二方向V2上直線狀地延伸。具體而言,蓋部32、33具備:第一蓋部32,從第一方向V1的一側覆蓋3個彎曲部31b、31d、31f;第二蓋部33,從第一方向V1的另一側覆蓋3個彎曲部31a、31c、31e。The cover parts 32 and 33 extend linearly in the second direction V2 so as to cover a plurality of (for example, six in this modification) curved parts 31 a to 31 f from the outside. Specifically, the cover parts 32 and 33 include: a first cover part 32 covering the three curved parts 31b, 31d, and 31f from one side in the first direction V1; and a second cover part 33 covering the other side from the first direction V1 The sides are covered with three bent portions 31a, 31c, and 31e.

第一蓋部32與彎曲部31b、31d、31f之間的間隔S2與相鄰的2個直部30a~30g之間的間隔S1為實質相同的大小。第一蓋部32與彎曲部31b、31d、31f之間的間隔例如是30mm左右。The space|interval S2 between the 1st cover part 32 and the curved parts 31b, 31d, and 31f and the space|interval S1 between two adjacent straight parts 30a-30g are substantially the same magnitude|size. The interval between the first cover portion 32 and the curved portions 31b, 31d, and 31f is, for example, about 30 mm.

第二蓋部33與彎曲部31a、31c、31e之間的間隔S3與相鄰的2個直部30a~30g之間的間隔S1為實質相同的大小。第二蓋部33中的蓋主體33a與彎曲部31a、31c、31e之間的間隔例如是30mm左右。另外,第二蓋部33中的延伸部33b與直部30a之間的間隔也是30mm左右。The space|interval S3 between the 2nd cover part 33 and the curved parts 31a, 31c, and 31e and the space|interval S1 between the two adjacent straight parts 30a-30g are substantially the same magnitude|size. The space|interval between the cover main body 33a in the 2nd cover part 33, and the curved parts 31a, 31c, 31e is about 30 mm, for example. In addition, the interval between the extension portion 33b and the straight portion 30a in the second cover portion 33 is also about 30 mm.

如上所述,根據本變形例,通過使紅外線加熱器6A的外部形狀的一邊的長度以及全長比第一實施方式的紅外線加熱器6的長度短,能夠實現紅外線加熱器6A的輕量化以及輕巧化。此外,本變形例的紅外線加熱器6A能夠毫無問題地作為低溫用(例如350℃~400℃的加熱溫度)的紅外線加熱器來使用,因此能夠實現低成本化。As described above, according to this modification, the length of one side and the overall length of the outer shape of the infrared heater 6A are made shorter than the length of the infrared heater 6 of the first embodiment, so that the weight and weight of the infrared heater 6A can be reduced. . In addition, since the infrared heater 6A of the present modification can be used as an infrared heater for low temperature (for example, a heating temperature of 350° C. to 400° C.) without any problem, cost reduction can be achieved.

(第二變形例) 接著,使用圖8對第一實施方式的第二變形例進行說明。 圖8是示出第一實施方式的紅外線加熱器的第二變形例的俯視圖。 在第二變形例中,相對於第一變形例,紅外線加熱器的形狀特別地不同。在圖8中,對與第一變形例相同的構成賦予相同的附圖標記,省略其詳細說明。(Second modification) Next, a second modification of the first embodiment will be described with reference to FIG. 8 . 8 is a plan view showing a second modification of the infrared heater of the first embodiment. In the second modification, the shape of the infrared heater is particularly different from the first modification. In FIG. 8 , the same reference numerals are given to the same structures as those of the first modification, and the detailed description thereof will be omitted.

<紅外線加熱器> 如圖8所示,本變形例的紅外線加熱器6B的全長比第一變形例的紅外線加熱器6A(參照圖7)的長度要長。例如,紅外線加熱器6B的全長為2070mm左右。另外,紅外線加熱器6B的外部形狀的一邊的長度為210mm左右。<Infrared heater> As shown in FIG. 8 , the entire length of the infrared heater 6B of the present modification is longer than the length of the infrared heater 6A (see FIG. 7 ) of the first modification. For example, the overall length of the infrared heater 6B is about 2070 mm. In addition, the length of one side of the outer shape of the infrared heater 6B is about 210 mm.

第一蓋部32與彎曲部31b、31d、31f之間的間隔比相鄰的2個直部30a~30g之間的間隔S1小。第一蓋部32與彎曲部31b、31d、31f之間的間隔例如是15mm左右。The interval between the first cover portion 32 and the curved portions 31b, 31d, and 31f is smaller than the interval S1 between the two adjacent straight portions 30a to 30g. The interval between the first cover portion 32 and the curved portions 31b, 31d, and 31f is, for example, about 15 mm.

第二蓋部33與彎曲部31a、31c、31e之間的間隔比相鄰的2個直部30a~30g之間的間隔S1小。第二蓋部33中的蓋主體33a與彎曲部31a、31c、31e之間的間隔S3例如是15mm左右。另外,第二蓋部33中的延伸部33b與直部30a之間的間隔是30mm左右。The interval between the second cover portion 33 and the curved portions 31a, 31c, and 31e is smaller than the interval S1 between the two adjacent straight portions 30a to 30g. The interval S3 between the cover main body 33a and the curved portions 31a, 31c, and 31e in the second cover portion 33 is, for example, about 15 mm. Moreover, the space|interval between the extension part 33b in the 2nd cover part 33, and the straight part 30a is about 30 mm.

如上所述,根據本變形例,通過使蓋部32、33與彎曲部31a~31f之間的間隔S2、S3比相鄰的2個直部30a~30g之間的間隔S1小,起到以下的效果。與蓋部32、33與彎曲部31a~31f之間的間隔S2、S3為相鄰的2個直部30a~30g之間的間隔S1以上的情況相比較,能夠更可靠地避免彎曲部31a~31f的露出,因此能夠更可靠地抑制彎曲部31a~31f與其他部分相比發生降溫。即,因為通過蓋部32、33能夠從外側更可靠地加熱彎曲部31a~31f的至少一部分,所以能夠更可靠地抑制彎曲部31a~31f與其他部分產生溫度差。因此,能夠更可靠地提高紅外線加熱器6B的溫度分佈的平衡。As described above, according to the present modification, by making the intervals S2 and S3 between the cover parts 32 and 33 and the curved parts 31a to 31f smaller than the interval S1 between the two adjacent straight parts 30a to 30g, the following Effect. Compared with the case where the distances S2 and S3 between the cover parts 32 and 33 and the curved parts 31a to 31f are equal to or larger than the distance S1 between the two adjacent straight parts 30a to 30g, the curved parts 31a to 31f can be avoided more reliably. 31f is exposed, so that it is possible to more reliably prevent the bent portions 31a to 31f from being lowered in temperature compared with other portions. That is, since at least a part of the curved parts 31a to 31f can be more reliably heated from the outside by the cover parts 32 and 33, the temperature difference between the curved parts 31a to 31f and other parts can be suppressed more reliably. Therefore, the balance of the temperature distribution of the infrared heater 6B can be improved more reliably.

(第二實施方式) 接著,使用圖9~圖12對本發明的第二實施方式進行說明。 圖9是第二實施方式的紅外線加熱器206的俯視圖。 在第二實施方式中,相對於第一實施方式,紅外線加熱器的形狀特別地不同。在圖9中,對與第一實施方式相同的構成賦予相同的附圖標記,省略其詳細說明。(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIGS. 9 to 12 .

The second cover portion 233 is connected to one end portion of the straight portion 30i on the other side in the second direction V2. The second cover portion 233 has a straight tubular shape having long sides in the second direction V2.

第一導入部34被配置於紅外線加熱器206的一角部。具體而言,第一導入部34被設置于第一蓋部32的一端。 第二導入部35被配置於所述一角部的對角部。具體而言,第二導入部35被設置于第二蓋部233的一端。即,在第一方向V1以及第二方向V2上,第二導入部35被配置在第一導入部34的相反側。The first introduction part 34 is arranged at a corner of the infrared heater 206 . Specifically, the first introduction portion 34 is provided at one end of the first cover portion 32 . The second introduction portion 35 is arranged at a diagonal portion of the one corner portion.

In addition, the surrounding plate 273 may not be provided. That is, the position adjustment portion 207 may include at least the first support plate 271 , the moving portion 275 , and the driving portion 279 . For example, an exterior cover that surrounds the entire apparatus may be provided.

第一支承板271的外周邊緣被連接於腔室2的周壁23的下端。第一支承板271也作為腔室2的底板起作用。在第一支承板271上配置有加熱部205。具體而言,加熱部205在腔室2內由第一支承板271支承。The outer peripheral edge of the first support plate 271 is connected to the lower end of the peripheral wall 23 of the chamber 2 . The first support plate 271 also functions as the bottom plate of the chamber 2 . The heating unit 205 is arranged on the first support plate 271 . Specifically, the heating unit 205 is supported by the first support plate 271 in the chamber 2 .

包圍板273與周壁23上下連續地相連。腔室2構成為能夠在密閉空間內容納基板10。例如通過利用熔接熔接等無間隙地接合頂板21、作為底板的第一支承板271以及周壁23的各連接部,能夠提高腔室2內的氣密性。The surrounding plate 273 is continuously connected up and down with the peripheral wall 23 . The chamber 2 is configured to be able to accommodate the substrate 10 in a closed space. The airtightness in the chamber 2 can be improved by joining the top plate 21 , the first support plate 271 serving as the bottom plate, and each connection portion of the peripheral wall 23 without a gap, for example, by welding or the like.

移動部275具備銷276、伸縮管277以及基台278。 銷276能夠支承基板10的第二表面10b,並且能夠在第二表面10b的法線方向(Z方向)上移動。銷276是上下延伸的棒狀構件。銷276的前端(上端)能夠抵接於基板10的第二表面10b,並且能夠遠離基板10的第二表面10b。The moving part 275 includes a pin 276 , a telescopic tube 277 , and a base 278 . The pins 276 can support the second surface 10b of the substrate 10 and can move in the normal direction (Z direction) of the second surface 10b. The pin 276 is a rod-shaped member extending up and down. The front end (upper end) of the pin 276 can abut against the second surface 10 b of the substrate 10 and can be away from the second surface 10 b of the substrate 10 .

在與第二表面10b平行的方向(X方向以及Y方向)上隔開間隔地設置有多個銷276。多個銷276分別形成為大致相同的長度。多個銷276的前端配置在與第二表面10b平行的面內(XY平面內)。A plurality of pins 276 are provided at intervals in the directions (X and Y directions) parallel to the second surface 10b. The plurality of pins 276 are each formed to have substantially the same length. The tips of the plurality of pins 276 are arranged in a plane parallel to the second surface 10b (in the XY plane).

伸縮管277被設置在第一支承板271與基台278之間。伸縮管277是以包圍銷276的周圍的方式進行覆蓋並且上下延伸的管狀構件。伸縮管277在第一支承板271與基台278之間上下自如地伸縮。伸縮管277例如是真空波紋管。The telescopic tube 277 is provided between the first support plate 271 and the base 278 . The telescopic tube 277 is a tubular member that covers the periphery of the pin 276 and extends up and down. The telescopic tube 277 can be freely extended and contracted up and down between the first support plate 271 and the base 278 . The telescopic tube 277 is, for example, a vacuum bellows.

伸縮管277設置有多個,與多個銷276的數量相同。多個伸縮管277的前端(上端)被固定于第一支承板271。具體而言,在第一支承板271上形成有使第一支承板271在厚度方向上開口的多個插通孔271h。各插通孔271h的內徑為與各伸縮管277的外徑大致相同大小。各伸縮管277的前端例如被嵌合固定于第一支承板271的各插通孔271h。A plurality of telescopic tubes 277 are provided in the same number as the plurality of pins 276 . Front ends (upper ends) of the plurality of telescopic tubes 277 are fixed to the first support plate 271 . Specifically, the first support plate 271 is formed with a plurality of insertion holes 271h that open the first support plate 271 in the thickness direction. The inner diameter of each insertion hole 271h is substantially the same size as the outer diameter of each telescopic tube 277 . The front end of each telescopic tube 277 is fitted and fixed to each insertion hole 271h of the first support plate 271, for example.

基台278是與第一支承板271對置的板狀構件。基台278的上表面呈沿著基板10的第二表面10b的平坦面。在基台278的上表面固定有多個銷276的基端(下端)以及多個伸縮管277的基端(下端)。The base 278 is a plate-like member facing the first support plate 271 .

多個銷276的前端可插通加熱部205。在加熱部205中,在第二表面10b的法線方向上與第一支承板271的各插通孔271h(各伸縮管277的內部空間)重疊的位置,形成有使加熱部205在第二表面10b的法線方向(電熱板的厚度方向)開口的多個插通孔205h。The front ends of the plurality of pins 276 can be inserted through the heating portion 205 . The heating portion 205 is formed so that the heating portion 205 is placed in the second surface 10b at a position overlapping each insertion hole 271h of the first support plate 271 (inner space of each telescopic tube 277) in the normal direction of the second surface 10b. The plurality of through holes 205h opened in the normal direction of the surface 10b (the thickness direction of the hot plate).

多個銷276的前端能夠經由各伸縮管277的內部空間以及加熱部205的各插通孔205h而抵接於基板10的第二表面10b。因此,通過多個銷276的前端能夠以平行於XY平面的方式支承基板10。多個銷276一邊支承容納在腔室2內的基板10,一邊沿腔室2內的Z方向移動(參照圖10~圖12)。The tips of the plurality of pins 276 can abut on the second surface 10b of the substrate 10 via the inner space of each telescopic tube 277 and each insertion hole 205h of the heating unit 205 . Therefore, the substrate 10 can be supported by the tips of the plurality of pins 276 so as to be parallel to the XY plane. The plurality of pins 276 move in the Z direction in the chamber 2 while supporting the substrate 10 accommodated in the chamber 2 (see FIGS. 10 to 12 ).

驅動部279被配置在腔室2的外部即容納部270內。因此即便假設隨著驅動部279的驅動而產生微塵,通過使腔室2內為密閉空間,也能夠避免微塵向腔室2內的入侵。The drive unit 279 is arranged outside the chamber 2 , that is, in the accommodating unit 270 . Therefore, even if it is assumed that fine dust is generated in accordance with the driving of the driving unit 279 , the intrusion of the fine dust into the chamber 2 can be avoided by making the inside of the chamber 2 a closed space.

<基板加熱方法> 接著,對本實施方式的基板加熱方法進行說明。在本實施方式中,使用上述的基板加熱裝置201對基板10進行加熱。在基板加熱裝置201的各構件進行的動作由控制部15控制。另外,對於與第一實施方式相同的工程,省略了其詳細說明。<Substrate heating method> Next, the substrate heating method of the present embodiment will be described. In this embodiment, the substrate 10 is heated using the above-described substrate heating apparatus 201 . The operations performed by the components of the substrate heating apparatus 201 are controlled by the control unit 15 . In addition, about the same process as 1st Embodiment, the detailed description is abbreviate|omitted.

本實施方式的基板加熱方法包括減壓工程、第一加熱工程以及第二加熱工程。 在減壓工程中,對塗布了聚醯亞胺形成用液的基板10進行減壓。 如圖10所示,在減壓工程中,基板10遠離加熱部205。具體而言,使多個銷276的前端經由各伸縮管277的內部空間以及加熱部205的各插通孔205h而抵接於基板10的第二表面10b,並且使基板10上升,由此使基板10遠離加熱部205。在減壓工程中,加熱部205以及基板10以加熱部205的熱量不會傳遞至基板10的程度遠離。在減壓工程中,接通加熱部205的電源。加熱部205的溫度,例如是250℃左右。另一方面,在減壓工程中,斷開紅外線加熱器206的電源。The substrate heating method of the present embodiment includes a decompression process, a first heating process, and a second heating process. In the decompression process, the substrate 10 to which the liquid for forming polyimide is applied is decompressed. As shown in FIG. 10 , in the decompression process, the substrate 10 is separated from the heating unit 205 . Specifically, the tips of the plurality of pins 276 are brought into contact with the second surface 10b of the substrate 10 via the inner spaces of the telescopic tubes 277 and the respective insertion holes 205h of the heating portion 205, and the substrate 10 is lifted, thereby making the The substrate 10 is away from the heating part 205 . In the decompression process, the heating unit 205 and the substrate 10 are separated to such an extent that the heat of the heating unit 205 is not transferred to the substrate 10 . In the decompression process, the power supply of the heating unit 205 is turned on. The temperature of the heating unit 205 is, for example, about 250°C. On the other hand, in the decompression process, the power supply of the infrared heater 206 is turned off.

在減壓工程之後,在第一加熱工程中,以加熱部205的溫度加熱基板10。 如圖11所示,在第一加熱工程中,通過使多個銷276的前端遠離基板10的第二表面10b,使基板10抵接加熱部205。即,使基板10載置在加熱部205的上表面。由此,因為加熱部205抵接基板10的第二表面10b,所以加熱部5的熱量會直接傳遞至基板10。加熱部205的溫度例如在第一加熱工程中維持在250℃。因此,基板溫度能夠上升到250℃。另一方面,在第一加熱工程中,紅外線加熱器206的電源一直處於斷開狀態。After the decompression process, in the first heating process, the substrate 10 is heated at the temperature of the heating unit 205 . As shown in FIG. 11 , in the first heating step, the tips of the plurality of pins 276 are moved away from the second surface 10 b of the substrate 10 , so that the substrate 10 is brought into contact with the heating portion 205 . That is, the substrate 10 is placed on the upper surface of the heating unit 205 . Accordingly, since the heating portion 205 is in contact with the second surface 10 b of the substrate 10 , the heat of the heating portion 5 is directly transferred to the substrate 10 . The temperature of the heating unit 205 is maintained at, for example, 250° C. in the first heating process. Therefore, the substrate temperature can be raised to 250°C. On the other hand, in the 1st heating process, the power supply of the infrared heater 206 is always in the OFF state.

第一加熱工程之後,在第二加熱工程中,以第二溫度對基板10進行加熱。 如圖12所示,在第二加熱工程中,通過使基板10上升到比第一加熱工程時的位置更高的位置,使基板10接近紅外線加熱器206。例如,在第二加熱工程中,加熱部205的溫度維持在250℃。此外,在第二加熱工程中,接通紅外線加熱器206的電源。例如,紅外線加熱器206能夠以450℃對基板10進行加熱。因此,基板溫度能夠上升到450℃。在第二加熱工程中,基板10比在第一加熱工程時更接近紅外線加熱器206,因此紅外線加熱器206的熱量被充分地傳遞至基板10。After the first heating process, in the second heating process, the substrate 10 is heated at the second temperature. As shown in FIG. 12 , in the second heating process, the substrate 10 is brought close to the infrared heater 206 by raising the substrate 10 to a position higher than the position in the first heating process. For example, in the second heating process, the temperature of the heating unit 205 is maintained at 250°C. In addition, in the second heating process, the power of the infrared heater 206 is turned on. For example, the infrared heater 206 can heat the substrate 10 at 450°C. Therefore, the substrate temperature can be raised to 450°C. In the second heating process, the substrate 10 is closer to the infrared heater 206 than in the first heating process, so the heat of the infrared heater 206 is sufficiently transferred to the substrate 10 .

之後,經過與第一實施方式相同的工程,進行塗布於基板10的聚醯亞胺形成用液的揮發或者醯亞胺化,並且進行塗布於基板10的聚醯亞胺形成用液的醯亞胺化時的分子鏈的再排列,能夠形成聚醯亞胺膜。After that, through the same process as in the first embodiment, volatilization or imidization of the polyimide-forming liquid applied to the substrate 10 is performed, and imidization of the polyimide-forming liquid applied to the substrate 10 is performed. The rearrangement of molecular chains during amination can form a polyimide film.

如上所述,根據本實施方式,在俯視狀態下,紅外線加熱器206的外部形狀呈矩形形狀,第一導入部34配置在紅外線加熱器206的一角部,第二導入部35配置在所述一角部的對角部,由此,在俯視狀態下,第一導入部34以及第二導入部35的配置位置以紅外線加熱器206的中心為基準而成為點對稱,並且第一導入部34以及第二導入部35較遠地遠離。由此,即便在第一導入部34以及第二導入部35與其他部分相比降溫的情況下,也不會降低相互的降溫溫度,從而能夠避免紅外線加熱器206局部地過度降溫,因此能夠盡可能地提高紅外線加熱器206的溫度分佈的平衡。As described above, according to the present embodiment, the outer shape of the infrared heater 206 is rectangular in plan view, the first introduction part 34 is arranged at a corner of the infrared heater 206 , and the second introduction part 35 is arranged at the corner Therefore, in a plan view, the arrangement positions of the first introduction part 34 and the second introduction part 35 are point-symmetrical with respect to the center of the infrared heater 206, and the first introduction part 34 and the second introduction part 35 The two introduction parts 35 are far away. Thereby, even when the temperature of the first introduction part 34 and the second introduction part 35 is lowered compared with other parts, the mutual cooling temperature is not lowered, and the temperature of the infrared heater 206 can be prevented from being locally excessively lowered. It is possible to improve the balance of the temperature distribution of the infrared heater 206 .

此外,在俯視狀態下,紅外線加熱器206呈點對稱形狀,由此與在俯視狀態下,紅外線加熱器206呈非對稱形狀的情況相比較,能夠更可靠地提高紅外線加熱器206的溫度分佈的平衡。In addition, since the infrared heater 206 has a point-symmetric shape in a plan view, compared with a case where the infrared heater 206 has an asymmetric shape in a plan view, the temperature distribution of the infrared heater 206 can be more reliably improved. balance.

此外,移動部275包括能夠支承基板10的第二表面10b、並且能夠在第二表面10b的法線方向上移動的多個銷276,多個銷276的前端被配置在與第二表面10b平行的面內,從而起到以下的效果。能夠在穩定地支承基板10的狀態下對基板10進行加熱,因此能夠使塗布於基板10的聚醯亞胺形成用液穩定地成膜。Further, the moving portion 275 includes a plurality of pins 276 capable of supporting the second surface 10b of the substrate 10 and capable of moving in a direction normal to the second surface 10b, and the tips of the plurality of pins 276 are arranged in parallel with the second surface 10b within the plane, so as to achieve the following effects. Since the substrate 10 can be heated in a state where the substrate 10 is stably supported, the polyimide-forming liquid applied to the substrate 10 can be stably formed into a film.

此外,在加熱部205中,形成有使加熱部205在第二表面10b的法線方向開口的多個插通孔205h,各銷276的前端能夠經由各插通孔205h抵接第二表面10b,從而起到以下的效果。能夠在短時間內進行基板10在多個銷276與加熱部205之間的交接,因此能夠高效地調整基板10的加熱溫度。In addition, the heating portion 205 is formed with a plurality of insertion holes 205h opening the heating portion 205 in the direction normal to the second surface 10b, and the tips of the pins 276 can abut on the second surface 10b via the insertion holes 205h. , so as to have the following effects. Since the transfer of the substrate 10 between the plurality of pins 276 and the heating unit 205 can be performed in a short time, the heating temperature of the substrate 10 can be adjusted efficiently.

The plurality of third infrared heaters 563a to 563d are laid out and arranged in a direction parallel to the first direction V1. In addition, the third infrared heaters 563a, 563b, 563c, and 563d are arranged in this order from one side toward the other side in the direction parallel to the first direction V1.

第二紅外線加熱器562a~562c,以與相鄰的2個第一紅外線加熱器561a~561d的邊界部鄰接的方式,在第二方向V2(與所述一方向交叉的方向)上與第一紅外線加熱器561a~561d鋪設地配置。進而,第二紅外線加熱器562a~562c,在第二方向V2上,以與相鄰的2個第三紅外線加熱器563a~563d的邊界部鄰接的方式,在第二方向V2上與第三紅外線加熱器563a~563d鋪設地配置。即,第二紅外線加熱器562a~562c在第二方向V2上配置為被夾於相鄰的2個第一紅外線加熱器561a~561d的邊界部與相鄰的2個第三紅外線加熱器563a~563d的邊界部之間。The second infrared heaters 562a to 562c are adjacent to the first infrared heaters 561a to 561d in the second direction V2 (the direction intersecting the one direction) so as to be adjacent to the boundary of the two adjacent first infrared heaters 561a to 561d. The infrared heaters 561a to 561d are laid out and arranged. Furthermore, the second infrared heaters 562a to 562c are connected to the third infrared heaters in the second direction V2 so as to be adjacent to the boundary of the two adjacent third infrared heaters 563a to 563d in the second direction V2. The heaters 563a to 563d are laid out. That is, the second infrared heaters 562a to 562c are arranged in the second direction V2 so as to be sandwiched between the boundary portions of the two adjacent first infrared heaters 561a to 561d and the adjacent two third infrared heaters 563a to 561d. 563d between the borders.

在俯視狀態下,第二紅外線加熱器562a~562c具有與第一紅外線加熱器561a~561d以及第三紅外線加熱器563a~563d相同的形狀。另外,第一紅外線加熱器561a~561d、第二紅外線加熱器562a~562c以及第三紅外線加熱器563a~563d,相當於第一實施方式的紅外線加熱器6。The second infrared heaters 562a to 562c have the same shape as the first infrared heaters 561a to 561d and the third infrared heaters 563a to 563d in a plan view. The first infrared heaters 561a to 561d, the second infrared heaters 562a to 562c, and the third infrared heaters 563a to 563d correspond to the infrared heaters 6 of the first embodiment.

如上所述,根據本實施方式,具備加熱器單元560,所述加熱器單元560構成為在一表面鋪設多個紅外線加熱器6,從而起到以下的效果。因為具備上述紅外線加熱器6,能夠提高加熱器單元560的溫度分佈的平衡。此外,在能夠個別地控制多個紅外線加熱器6的情況下,因為能夠使一部分的紅外線加熱器6的輸出比其他的紅外線加熱器6的輸出大,所以相對於基板10能夠進行溫度分佈良好的加熱。例如,在基板10的四角的溫度較低的情況下,使配置在與該部分對應的位置的紅外線加熱器6的輸出比其他的紅外線加熱器6的輸出大,由此僅提高該部分的溫度,從而能夠提高基板10整體的溫度分佈。As described above, according to the present embodiment, the heater unit 560 provided with the plurality of infrared heaters 6 on one surface provides the following effects. Since the infrared heater 6 described above is provided, the balance of the temperature distribution of the heater unit 560 can be improved. In addition, when the plurality of infrared heaters 6 can be individually controlled, since the output of some of the infrared heaters 6 can be made larger than the output of the other infrared heaters 6, it is possible to achieve a favorable temperature distribution with respect to the substrate 10. heating. For example, when the temperature of the four corners of the substrate 10 is low, the output of the infrared heater 6 arranged at the position corresponding to the portion is made larger than the output of the other infrared heaters 6, thereby increasing the temperature of only that portion. , so that the temperature distribution of the entire substrate 10 can be improved.

此外,加熱器單元560包括:多個第一紅外線加熱器561a~561d,沿第一方向V1鋪設地配置;多個第二紅外線加熱器562a~562c,沿與第一方向V1平行的方向鋪設地配置,第二紅外線加熱器562a~562c,以與相鄰的2個第一紅外線加熱器561a~561d的邊界部鄰接的方式,在與第一方向V1交叉的第二方向V2上與第一紅外線加熱器561a~561d鋪設地配置,從而起到以下的效果。因為第一紅外線加熱器561a~561d的溫度分佈與第二紅外線加熱器562a~562c的溫度分佈能夠相互地補足,所以能夠更進一步地提高加熱器單元560的溫度分佈的平衡。 進而,在第二方向V2上,第二紅外線加熱器562a~562c與第三紅外線加熱器563a~563d鋪設地配置為使得第二紅外線加熱器562a~562c與相鄰的2個第三紅外線加熱器563a~563d的邊界部鄰接。因為第三紅外線加熱器563a~563d的溫度分佈與第二紅外線加熱器562a~562c的溫度分佈能夠相互地補足,所以能夠更進一步地提高加熱器單元560的溫度分佈的平衡。In addition, the heater unit 560 includes: a plurality of first infrared heaters 561a to 561d, which are laid out along the first direction V1; and a plurality of second infrared heaters 562a to 562c, which are laid out in a direction parallel to the first direction V1. The second infrared heaters 562a to 562c are arranged such that the second infrared heaters 562a to 562c are adjacent to the boundary of the two adjacent first infrared heaters 561a to 561d, and are connected to the first infrared rays in the second direction V2 intersecting with the first direction V1. The heaters 561a to 561d are arranged so as to be laid, and the following effects are obtained. Since the temperature distribution of the first infrared heaters 561a to 561d and the temperature distribution of the second infrared heaters 562a to 562c can complement each other, the balance of the temperature distribution of the heater unit 560 can be further improved. Furthermore, in the second direction V2, the second infrared heaters 562a to 562c and the third infrared heaters 563a to 563d are laid out so that the second infrared heaters 562a to 562c and the adjacent two third infrared heaters The boundary portions of 563a to 563d are adjacent to each other. Since the temperature distribution of the third infrared heaters 563a to 563d and the temperature distribution of the second infrared heaters 562a to 562c can complement each other, the balance of the temperature distribution of the heater unit 560 can be further improved.

此外,在俯視狀態下,第二紅外線加熱器562a~562c具有與第一紅外線加熱器561a~561d以及第三紅外線加熱器563a~563d相同的形狀,從而起到以下的效果。與在俯視狀態下第二紅外線加熱器562a~562c具有第一紅外線加熱器561a~561d以及第三紅外線加熱器563a~563d不同的形狀的情況相比,能夠更可靠地提高加熱器單元560的溫度分佈的平衡。此外,即便改變基板尺寸,也能夠通過改變紅外線加熱器6的個數,等間隔地配置紅外線加熱器6,而能夠對基板10進行溫度分佈良好的加熱。然而,在紅外線加熱器為單純的直管的情況下,若基板尺寸變大,則須要使直管的長度伸長,因此存在難以容許紅外線加熱器的熱膨脹的可能性。但是,根據本實施方式之構成,即便基板尺寸變大,紅外線加熱器6的尺寸也不會改變,因此能夠容易地容許紅外線加熱器6的熱膨脹。In addition, the second infrared heaters 562a to 562c have the same shape as the first infrared heaters 561a to 561d and the third infrared heaters 563a to 563d in a plan view, and the following effects are obtained. Compared with the case where the second infrared heaters 562a to 562c have different shapes from the first infrared heaters 561a to 561d and the third infrared heaters 563a to 563d in a plan view, the temperature of the heater unit 560 can be raised more reliably distribution balance. In addition, even if the substrate size is changed, by changing the number of infrared heaters 6 and arranging the infrared heaters 6 at equal intervals, the substrate 10 can be heated with a favorable temperature distribution. However, when the infrared heater is a simple straight tube, if the size of the substrate becomes large, the length of the straight tube needs to be extended, so that it may be difficult to tolerate thermal expansion of the infrared heater. However, according to the configuration of the present embodiment, even if the size of the substrate increases, the size of the infrared heater 6 does not change, so the thermal expansion of the infrared heater 6 can be easily tolerated.

(第五實施方式) 接著,使用圖15對本發明的第五實施方式進行說明。 圖15是第五實施方式的加熱器單元660的俯視圖。 在第五實施方式中,相對於第四實施方式,紅外線加熱器的配置方案特別地不同。在圖15中,對與第四實施方式相同的構成賦予相同的附圖標記,省略其詳細說明。(Fifth Embodiment) Next, a fifth embodiment of the present invention will be described with reference to FIG. 15 . FIG. 15 is a plan view of a heater unit 660 of the fifth embodiment. In the fifth embodiment, the configuration of the infrared heater is particularly different from the fourth embodiment. In FIG. 15 , the same reference numerals are assigned to the same components as those of the fourth embodiment, and detailed descriptions thereof will be omitted.

<加熱器單元> 如圖15所示,本實施方式的加熱器單元660,具備第一紅外線加熱器組561、第二紅外線加熱器組662以及第三紅外線加熱器組563。<Heater unit> As shown in FIG. 15 , the heater unit 660 of the present embodiment includes a first infrared heater group 561 , a second infrared heater group 662 , and a third infrared heater group 563 .

在俯視狀態下,第二紅外線加熱器662a~662c具有使第一紅外線加熱器561a~561d或者第三紅外線加熱器563a~563d旋轉90度後的形狀。具體而言,在俯視狀態下,第二紅外線加熱器662a~662c,具有使第一紅外線加熱器561a~561d或者第三紅外線加熱器563a~563d以其中心為起點向右(順時針)旋轉90度後的形狀。另外,第一紅外線加熱器561a~561d、第二紅外線加熱器662a~662c以及第三紅外線加熱器563a~563d相當於第一實施方式的紅外線加熱器6。The second infrared heaters 662a to 662c have a shape obtained by rotating the first infrared heaters 561a to 561d or the third infrared heaters 563a to 563d by 90 degrees in a plan view. Specifically, in a plan view, the second infrared heaters 662a to 662c have the function of rotating the first infrared heaters 561a to 561d or the third infrared heaters 563a to 563d by 90 degrees to the right (clockwise) from the center of the heater. shape after degrees. The first infrared heaters 561a to 561d, the second infrared heaters 662a to 662c, and the third infrared heaters 563a to 563d correspond to the infrared heater 6 of the first embodiment.

如上所述,根據本實施方式,在俯視狀態下,第二紅外線加熱器662a~662c具有使第一紅外線加熱器561a~561d或者第三紅外線加熱器563a~563d旋轉90度後的形狀,由此利用第一紅外線加熱器561a~561d、第二紅外線加熱器662a~662c與第三紅外線加熱器563a~563d,能夠相互地補足由紅外線加熱器6的形狀引起的溫度分佈,所以能夠更進一步地提高加熱器單元660的溫度分佈的平衡。As described above, according to the present embodiment, the second infrared heaters 662a to 662c have shapes obtained by rotating the first infrared heaters 561a to 561d or the third infrared heaters 563a to 563d by 90 degrees in a plan view. By the first infrared heaters 561a to 561d, the second infrared heaters 662a to 662c, and the third infrared heaters 563a to 563d, since the temperature distribution caused by the shape of the infrared heater 6 can be mutually complemented, the temperature distribution can be further improved. Balance of the temperature distribution of the heater unit 660 .

另外,在上述的例子中示出的各構成構件的諸形狀或組合等為一例,基於設計要求等能夠進行各種變更。 此外,雖然在上述實施方式中,基板、加熱部以及紅外線加熱器被容納於共用的腔室內,但是本發明並不限定於此。例如,也可以是加熱部以及紅外線加熱器被容納於相互不同的腔室。In addition, the shapes, combinations, and the like of the respective constituent members shown in the above-mentioned examples are only examples, and various changes can be made based on design requirements and the like. In addition, in the above-mentioned embodiment, although the board|substrate, the heating part, and the infrared heater are accommodated in the common chamber, this invention is not limited to this. For example, the heating unit and the infrared heater may be accommodated in different chambers.

此外,雖然在上述實施方式中,加熱部以及紅外線加熱器兩者都能夠階段性地加熱基板,但是本發明並不限定於此。例如,也可以是加熱部以及紅外線加熱器的至少一方能夠階段性地加熱基板。此外,也可以是加熱部以及紅外線加熱器兩者都僅能以恆定的溫度加熱基板。In addition, in the said embodiment, although both the heating part and the infrared heater can heat a board|substrate in stages, this invention is not limited to this. For example, at least one of the heating unit and the infrared heater may be capable of heating the substrate in steps. In addition, both the heating unit and the infrared heater may heat the substrate only at a constant temperature.

此外,可以在上述實施方式中使腔室的內壁能夠反射紅外線。例如,可以是使腔室的內壁為由鋁等的金屬形成的鏡面(反射面)。由此,與使腔室的內壁能夠吸收紅外線的材質相比較,能夠提高腔室內的溫度均勻性。In addition, the inner wall of the chamber may be made to reflect infrared rays in the above-described embodiment. For example, the inner wall of the chamber may be a mirror surface (reflection surface) formed of metal such as aluminum. Thereby, the temperature uniformity in the chamber can be improved compared with the material which enables the inner wall of the chamber to absorb infrared rays.

此外,雖然在上述實施方式中,使用了多個輸送輥作為輸送部,但是本發明並不限定於此。例如,作為輸送部,可以使用傳送帶,也可以使用線性電機致動器。例如,也可為能夠在X方向上添加傳送帶以及線性電機致動器。由此,能夠調整X方向中的基板的輸送距離。In addition, in the said embodiment, although a some conveyance roller was used as a conveyance part, this invention is not limited to this. For example, as a conveying part, a conveyor belt may be used, and a linear motor actuator may be used. For example, it is also possible to add conveyor belts and linear motor actuators in the X direction. Thereby, the conveyance distance of the board|substrate in X direction can be adjusted.

此外,也可以在採用圖3所示的構成(在輸送部中形成有通過部的構成)以外的構成作為輸送部的情況下,使得加熱部在俯視狀態下的尺寸大於等於基板在俯視狀態下的尺寸。由此,與使加熱部在俯視狀態下的尺寸比基板在俯視狀態下的尺寸小的情況相比較,能夠更進一步提高基板的加熱溫度的面內均勻性。In addition, when a configuration other than the configuration shown in FIG. 3 (the configuration in which the passage portion is formed in the transfer portion) is used as the transfer portion, the size of the heating portion in a plan view may be equal to or greater than that of the substrate in a plan view size of. This makes it possible to further improve the in-plane uniformity of the heating temperature of the substrate compared to the case where the size of the heating portion in the plan view is smaller than the size of the substrate in the plan view.

此外,雖然在上述實施方式中,在減壓工程以及第一加熱工程中,接通加熱部的電源,斷開紅外線加熱器的電源,但是本發明並不限定於此。例如,也可以是,在減壓工程以及第一加熱工程中接通加熱部以及紅外線加熱器的電源。In addition, in the above-mentioned embodiment, in the decompression process and the first heating process, the power supply of the heating unit is turned on and the power supply of the infrared heater is turned off, but the present invention is not limited to this. For example, in the decompression process and the first heating process, the power of the heating unit and the infrared heater may be turned on.

此外,也可以是在上述實施方式中,在俯視狀態下紅外線加熱器的外部形狀呈矩形形狀,第一導入部以及第二導入部在紅外線加熱器的一邊的中央部對置地配置。根據該構成,因為第一導入部與第二導入部一定程度地遠離,所以能夠抑制紅外線加熱器局部地降溫。因此,能夠提高紅外線加熱器的溫度分佈的平衡。In addition, in the above-described embodiment, the outer shape of the infrared heater may be a rectangular shape in plan view, and the first introduction portion and the second introduction portion may be arranged to face each other at the center portion of one side of the infrared heater. According to this structure, since the 1st introduction part and the 2nd introduction part are spaced apart to some extent, it can suppress that an infrared heater is cooled locally. Therefore, the balance of the temperature distribution of the infrared heater can be improved.

另外,作為上述實施方式或者其變形例而記載的各構成要素,在不脫離本發明的主旨的範圍內,能夠進行適當組合,此外,也可以在組合得到的多個構成要素之中,適當地不使用一部分的構成要素。In addition, the respective constituent elements described as the above-described embodiment or its modification examples can be appropriately combined within the scope of not departing from the gist of the present invention, and further, among the plurality of constituent elements obtained by combining, appropriately Some components are not used.

(實施例) 以下,通過實施例對本發明更具體地進行說明,但是本發明並不受以下的實施例的限定。(Example) Hereinafter, the present invention will be described in more detail by way of examples, but the present invention is not limited by the following examples.

本發明人通過以下的評價確認了:通過使紅外線加熱器包括以從外側覆蓋彎曲部的方式配置的蓋部,能夠提高紅外線加熱器的溫度分佈的平衡。The inventors of the present invention have confirmed through the following evaluation that the balance of the temperature distribution of the infrared heater can be improved by including the infrared heater with the cover portion arranged so as to cover the bent portion from the outside.

(比較例) 比較例的紅外線加熱器使用僅具備直部以及彎曲部的紅外線加熱器。即,在比較例中不具備蓋部。(Comparative example) As the infrared heater of the comparative example, an infrared heater having only a straight portion and a curved portion was used. That is, in the comparative example, the lid portion is not provided.

(實施例) 實施例的紅外線加熱器使用具備直部、彎曲部以及蓋部的紅外線加熱器。即,相對於比較例,實施例的紅外線加熱器還具備蓋部。另外,實施例的紅外線加熱器相當於第一實施方式的紅外線加熱器6(參照圖2)。(Example) The infrared heater of the Example used the infrared heater provided with a straight part, a curved part, and a cover part. That is, compared with the comparative example, the infrared heater of the Example is further provided with the cover part. In addition, the infrared heater of the Example corresponds to the infrared heater 6 (refer FIG. 2) of 1st Embodiment.

(評價條件) 以下,對比較例以及實施例中的、通過紅外線加熱器進行加熱時的基板的溫度分佈的評價條件進行說明。 使用玻璃基板作為基板。基板配置在紅外線加熱器的正下方。基板的溫度為450℃。 在基板中,對與直部的長度方向中央部對應的部分(即,在基板的法線方向重疊的部分)的溫度(以下稱為“直部溫度”)進行測量。此外,在基板中,對與彎曲部對應的部分(即,在基板的法線方向重疊的部分)的溫度(以下稱為“彎曲部溫度”)進行測量。而且,算出直部溫度與彎曲部溫度差(以下稱為“溫度差”)。(evaluation conditions) Hereinafter, the evaluation conditions of the temperature distribution of the board|substrate at the time of heating with an infrared heater in a comparative example and an Example are demonstrated. A glass substrate was used as the substrate. The substrate is arranged just below the infrared heater. The temperature of the substrate was 450°C. In the substrate, the temperature of the portion corresponding to the longitudinal center portion of the straight portion (ie, the portion overlapping in the normal line direction of the substrate) (hereinafter referred to as “straight portion temperature”) is measured. In addition, in the substrate, the temperature of the portion corresponding to the bent portion (ie, the portion overlapping in the normal line direction of the substrate) (hereinafter referred to as “curved portion temperature”) was measured. Then, the temperature difference between the straight portion and the curved portion (hereinafter referred to as "temperature difference") was calculated.

(通過紅外線加熱器進行加熱時的基板的溫度分佈的評價結果) 在比較例的情況下,彎曲部比直部暗。由此可知彎曲部溫度比直部溫度低。在比較例的情況下,溫度差為5.8℃。(Evaluation result of temperature distribution of substrate when heated by infrared heater) In the case of the comparative example, the curved portion is darker than the straight portion. From this, it can be seen that the temperature of the curved portion is lower than that of the straight portion. In the case of the comparative example, the temperature difference was 5.8°C.

在實施例的情況下,彎曲部比直部暗。但是,實施例的彎曲部比比較例的彎曲部亮。由此可知,即便在實施例中,彎曲部溫度比直部溫度低,但是其降低程度比比較例小。在實施例的情況下,溫度差為2.4℃。 如上所述可知,通過使紅外線加熱器包括以從外側覆蓋彎曲部的方式配置的蓋部,能夠提高紅外線加熱器的溫度分佈的平衡。此外,可知能夠提高基板的溫度分佈。In the case of the embodiment, the curved portion is darker than the straight portion. However, the curved portion of the example is brighter than the curved portion of the comparative example. From this, it can be seen that even in the examples, the temperature of the curved portion is lower than the temperature of the straight portion, but the degree of decrease is smaller than that of the comparative example. In the case of the examples, the temperature difference was 2.4°C. As described above, it was found that the balance of the temperature distribution of the infrared heater can be improved by including the cover portion arranged so as to cover the bent portion from the outside. Moreover, it turned out that the temperature distribution of a board|substrate can be improved.
