確度來調節基板的浮起量,基板的浮起量例如可控制爲 ΙΟΟμπι以下,而50μιη以下較佳。 基板搬出區域2 2,是用來將塗佈有光阻劑的基板8 搬出到裝置外部的部位,具有:搬出側載台2 8、與升降機 構2 9。該搬出側載台2 8,設置在相對於處理載台2 7的+ X 方向側,由與設置在基板搬入區域2 0的搬入側載台2 5大 致相同的材質、尺寸所構成。與搬入側載台2 5同樣地, 在搬出側載台2 8設置有:空氣噴出孔2 8 a及升降銷出 '沒 孔2 8b。升降機構29,設置在搬出側載台28的基板搬出 位置的背面側,例如以框架部2 4來支承。升降機構2 9的 •15- 200918175 升降構件29a及升降銷29b,與設置在基板搬入區域20的 升降機構26的各部位爲相同的構造。該升降機構29,當 將搬出側載台2 8上的基板S搬出到外部裝置時,能藉由 基板S交接用的升降銷2

,是設置成在Y方向跨越處理載台27。支柱構件31a,在 處理載台27的Y方向側各設置有一個,各支柱構件31a 分別支承於框架部24的Y方向側的兩側面。各支柱構件 3 1 a,是設置成讓其上端部的高度位置一致。架橋構件3 1 b ,是架橋於各支柱構件3 1 a的上端部之間,相對於該支柱 構件3 1 a可進行升降。 該門型框架31是連接於移動機構31c,可朝X方向 移動。藉由該移動機構31c讓門型框架31可在其與管理 部4之間移動。也就是說,設置於門型框架31的噴嘴32 可在其與管理部4之間移動。 噴嘴32,是作成其中一方向爲長軸的長條狀,是設置 在門型框架31的架橋構件31b的-Z方向側的面部。在該 噴嘴32之中的-Z方向的前端,沿著本身的長軸方向設置 有狹縫狀的開口部32a,從該開口部32a將光阻劑吐出。 噴嘴3 2,其開口部3 2 a的長軸方向與噴嘴3 2本身的長軸 方向(Y方向)平行,並且該開口部32a配置成與處理載台 27相對向。開口部32a的長軸方向的尺寸是較所搬運的基 板S的Y方向的尺寸更小,而不會將光阻劑塗佈到基板s 的周邊區域。在噴嘴3 2的內部設置有使光阻劑流通到開 口部3 2 a的沒有圖示的流通路。在支柱構件3 1 a設置有·沒 -17- 200918175 有圖示的移動機構,藉由該移動機構,讓在架橋構件31b 所保持的噴嘴32可朝Z方向移動。而也可在門型框架31 的架橋構件31b下面安裝:用來將噴嘴32的開口部32a ’ 也就是噴嘴3 2的前端以及與該噴嘴前端相對向的相對向 面之間的Z方向上的距離予以測定的感應器3 4。 泵浦3 3,是將光阻劑供給到噴嘴3 2的流通路的光阻 劑供給手段。該泵浦3 3,如第1圖〜第4圖所示,在門型 框架31的架橋構件31b上面沿著噴嘴32的長軸方向配置 有兩個,該兩個泵浦3 3配置在相對於噴嘴3 2互相爲大致 相同距離的位置。這裡是分別將泵浦3 3配置在例如在Y 方向將架橋構件31b大致分成三等分的位置。 作爲該泵浦,適合使用例如膜片泵、高精度定量吐出 栗浦(tubephragm Pump)、手動活塞泵浦等。在這些栗浦之 中,高精度定量吐出泵浦(tubephragm Pump)最適合。 (管理部) 以下說明管理部4的構造。 管理部4,是爲了讓吐出到基板S的光阻劑(液狀體) 的吐出量爲定量而將噴嘴32進行管理的部位,是設置在 :基板搬運部2之中的相對於塗佈部3的-X方向側(基板 搬運方向的上游側)。該管理部4,具有:預備吐出機構 41、浸漬槽42、噴嘴洗淨裝置43、將這些構造予以收容 的收容部44、以及用來保持該收容部的保持構件45。保 持構件45與移動機構45a連接。藉由該移動機構45a讓 -18- 200918175 收容部44可朝X方向移動。 浸 上 門 〇 是 置 置 使 設 於 置 的 部 3 2 出 洗 洗 預備吐出機構4 1 '浸漬槽4 2、及噴嘴洗淨裝置4 3 是以該順序朝-X方向側排列。該等預備吐出機構4 1、 漬槽42、及噴嘴洗淨裝置43的Y方向的各尺寸,是較 述門型框架3 1的支柱構件3 1 a之間的距離更小,上述 型框架3 1是跨越各部分來接達。 預備吐出機構4 1,是預備性地將光阻劑吐出的部分 該預備吐出機構4 1設置成最接近噴嘴32。浸漬槽42, 在內部儲存有稀釋劑或光阻劑等的液體槽。噴嘴洗淨裝 43,是用來將噴嘴32的開口部32a附近予以沖洗的裝 ,是具有:朝γ方向移動的沒有圖示的洗淨機構、以及 該洗淨機構移動的沒有圖示的移動機構。該移動機構, 置在較洗淨機構更靠-X方向側。噴嘴洗淨裝置43,由 設置有移動機構,與預備吐出機構4 1及浸漬槽42相比 其X方向的尺寸較大。 當將該噴嘴洗淨裝置43配置在接近噴嘴32的位 (+ X方向側)時,則將其他部位配置到距離噴嘴3 2較遠 位置(-X方向側)。在這種情況,當噴嘴3 2接達到收容 44內的其他部位時會需要通過移動機構,藉此讓噴嘴 的移動距離變長。 本實施方式的噴嘴洗淨裝置43是設置在較預備吐 機構41及浸漬槽42更靠-X方向側的位置,並且噴嘴 淨裝置43的移動機構是設置在較該噴嘴洗淨裝置43的 淨機構更靠-X方向側,所以噴嘴32不會通過移動機構 -19- 200918175 配置成盡量縮短噴嘴32的移動距離。而當然針對預備吐 出機構41、浸漬槽42、噴嘴洗淨裝置43的配置方式,並 不限於本實施方式的配置方式’也可以用其他的配置方式 (塗佈裝置的動作) 接著來說明如上述構造的塗佈裝置1的動作。 第5圖是塗佈裝置1的動作的時序圖。如第5圖所示 ,在塗佈裝置1,進行:基板搬入、光阻劑塗佈、基板搬 出、預備吐出、光阻劑充塡(泵浦充塡)的各個動作。以下 說明將光阻劑塗佈到基板S的動作。 第6圖〜第9圖,是顯不塗佈裝置1的基板搬入、光 阻劑塗佈、基板搬出的各動作的俯視圖。將基板S搬入到 基板搬入區域20,使該基板S浮起而進行搬運,且在塗 佈處理區域2 1塗佈光阻劑,將已塗佈好該光阻劑的基板 S從基板搬出區域22搬出。第7圖〜第9圖僅以虛線顯 示門型框架3 1的輪廓,而容易判斷噴嘴32及處理載台27 的構造。以下來說明各部分的詳細動作。 在將基板搬入到基板搬入區域20之前,使塗佈裝置1 待機。具體來說,在搬入側載台25的基板搬入位置的-Y 方向側配置搬運機23a,將真空襯墊23b的高度位置定位 在基板的浮起高度位置,並且從搬入側載台2 5的空氣噴 出孔25a、處理載台27的空氣噴出孔27a、空氣吸引孔 2 7 b及搬出側載台2 8的空氣噴出孔2 8 a分別將空氣噴出或 -20- 200918175 吸引’成爲將空氣供給到讓基板浮起於各載台表面 的狀態。而預先將光阻劑充塡到泵浦3 3內。具體 是預先將在預備吐出動作及該預備吐出動作後的光 佈所需要的分量的光阻劑,分別充塡在兩個泵浦3 3 (1)基板搬入 在該狀態’例如藉由沒有圖示的搬運臂等,如彳 所示’若從外部將基板S搬運到基板搬入位置,則 構件2 6 a朝+ Z方向移動,將升降銷2 6 b從升降銷 25b突出到載台表面25c。而藉由升降銷26b將基;| 起,進行該基板S的交接動作。而從校準裝置25d 使定位構件突出於載台表面25c。 在接收基板S之後,使升降構件2 6 a下降將 2 6 b收容於升降銷出沒孔2 5 b內。此時,由於在載 25c形成有空氣層,所以基板S藉由該空氣而保持 於載台表面25c浮起的狀態。當基板s到達空氣層 時’藉由校準裝置25d來進行基板S的定位,將在 入位置的-Y方向側處配置的搬運機2 3 a的真空襯墊 空吸附於基板s的-Y方向側端部。在第7圖顯示 基板S的-Y方向側端部的狀態。 (2)預備吐出 在將光阻劑塗佈到基板S之前,在塗佈部3, 來保持噴嘴3 2的吐出狀態的預備吐出動作。該預 的程度 來說, 阻劑塗 內。 第6圖 使升降 出沒孔 反S抬 的長孔 升降銷 台表面 爲相對 的表面 基板搬 23b真 吸附住 進行用 備吐出 -21 - 200918175 動作,與開始搬入基板大致同時進行。首先如第1 0圖所 示,藉由移動機構31c(顯示於第4圖)使門型框架31朝-X 方向移動到管理部4的位置。 在使門型框架3 1移動到管理部4的位置之後,調整 門型框架3 1的位置將噴嘴32接達到噴嘴洗淨裝置43。在 噴嘴洗淨裝置43,朝向噴嘴32的開口部32a附近而吐出 稀釋劑等的洗淨液,並且因應需要將氮氣與稀釋劑同時吐 出到噴嘴3 2的開口部3 2 a,且同時藉由將沒有圖示的洗淨 機構朝向噴嘴3 2的長軸方向掃描,將噴嘴3 2洗淨。 在洗淨好噴嘴3 2之後,將該噴嘴3 2接達到預備吐出 單元41。在預備吐出單元41,會一邊將開口部32a與預 備吐出面之間的距離予以測定,一邊將噴嘴3 2的開口部 3 2a移動到Z方向上的預定位置,一邊使噴嘴32朝-X方 向移動,一邊從開口部3 2a預備吐出光阻劑。在該預備吐 出動作,在設置有兩個的泵浦33之中,在充塡有光阻劑 的其中一方的泵浦3 3,將內部的光阻劑壓送到噴嘴3 2的 流通路。 在進行了預備吐出動作之後,將門型框架3 1回到原 來位置,當要搬運下個基板S時,如第11圖所示,藉由 移動機構3 1 b使噴嘴3 2移動到Z方向上的預定位置。. 而也可因應需要,例如每預定次數接達到管理部4, 則使該噴嘴3 2接達到浸漬槽42內。在浸漬槽42,藉由將 噴嘴32的開口部32a暴露於:儲存於浸漬槽42的溶劑( 稀釋劑)的蒸氣環境中,來防止噴嘴3 2乾燥。 -22- 200918175 (塗佈) 在藉由真空襯墊23b吸附住基板s的-Y方向側端部 之後,使搬運機23a沿著軌道23c移動。由於基板S爲浮 起的狀態,所以即使搬運機2 3 a的驅動力較小,基板s也 能沿著軌道23 C順利移動。當基板S從搬入側載台25朝 處理載台27移動時’在處理載台27該基板的浮起量爲 ΙΟΟμιη,而50μπι以下較佳。 —旦基板S的搬運方向前端到達噴嘴32的開口部32a 的位置,則進行將光阻劑塗佈到基板S上。在光阻劑塗佈 動作,在設置有兩個的泵浦33之中,在預備吐出動作進 行壓送的泵浦3 3,再次將泵浦3 3內的光阻劑壓送到噴嘴 3 2的流通路。所壓送的光阻劑,如第7圖所示,從開口部 3 2a(顯示於第4圖)朝向基板S吐出。該光阻劑的吐出動作 ,是使噴嘴32的位置固定,藉由搬運機23a —邊搬運基 板S —邊來進行。伴隨著基板S的移動,則如第8圖所示 在基板S上塗佈光阻膜R。藉由讓基板S通過,吐出光阻 劑的開口部32a下面,而在基板S的預定區域形成光阻膜 R。 形成了光阻膜R的基板S,是藉由搬運機23a將其朝 向搬出側載台2 8搬運。在搬出側載台2 8,在相對於載台 表面28C浮起的狀態,如第9圖所示將基板S搬運到基板 搬出位置。 (4)基板搬出 -23- 200918175 一旦基板S到達基板搬出位置,則解除真空襯墊23b 的吸附。解除基板S的吸附之後,搬運機23a再回到搬入 側載台25的基板搬入位置。而解除吸附後,使升降機構 29的升降構件29a朝向+Z方向移動。伴隨著升降構件 29a的移動,升降銷29b從升降銷出沒孔28b朝向基板S 的背面突出,藉由升降銷2 9 b將基板S抬起。在該狀態, 例如在搬出側載台2 8的+X方向側處設置的外部的搬運臂 ,會接達於搬出側載台28,而接收基板S。以這種方式進 行基板S的搬出。 (5)泵浦充塡 泵浦充塡動作,在光阻劑的吐出完成之瞬後開始。在 吐出光阻劑之瞬後,在該光阻劑的吐出所使用的泵浦3 3 的光阻劑保持部3 3 a變空。在光阻劑充塡動作,該泵浦3 3 會作動,將光阻劑充塡到變空的內部。在充塡光阻劑的途 中’將基板S搬運到搬出側載台2 8,進行基板S的搬出 動作。 (6)下個基板搬入 上述基板的下個基板(以下稱爲「下個基板」)S2的搬 入’是與上述基板S的搬出動作的開始時間大致同時來進 行。針對搬入動作,與上述基板S的搬入動作一樣,利用 升降銷2 6 b來接收下個基板s 2之後,將其浮起保持於搬 入側載台25上,進行校準動作。在上述基板S搬出時已 -24- 200918175 回到基板搬入位置的搬運機23a,在下個基板S2的校準動 作完成之前,會回到基板搬入位置。下個基板S2,會被 回到基板搬入位置的搬運機2 3 a的吸附襯墊2 3 b所吸附。 (7) 下個基板的預備吐出 在上述(3 )所說明的基板搬運、光阻劑塗佈動作完成之 後,進行將光阻劑吐出到下個基板S 2的預備吐出動作。 針對該預備吐出動作的內容,是與上述(2)所說明的內容相 同。在該預備吐出動作,是藉由在兩個泵浦33之中與在 上述(2)、(3)進行壓送的栗浦33不同的泵浦33來進行壓 送。當下個基板的預備吐出動作開始時,在上述(2)及(3) 已進行壓送的泵浦3 3會處於進行光阻劑充塡動作的狀態 。與下個基板S2的搬入動作完成的時機大致相同的時機 ’下個基板的預備吐出動作也完成。於是,該下個基板預 備吐出動作,會與上述基板S的搬出動作、下個基板S2 的搬入動作、及光阻劑充塡動作一起進行。 (8) 下個基板的塗佈 將下個基板S2搬入到搬入側載台25,藉由吸附襯墊 23b將其吸附之後,則將該下個基板S2朝處理載台27搬 運。將下個基板S2搬運到處理載台27之後,則將光阻劑 塗佈到該下個基板S 2。針對該下個基板S 2的搬運動作及 塗佈動作的內容,與在上述(2)及(3)所說明的內容相同。 在該塗佈動作中,是藉由在兩個泵浦33之中當上述(7)的 -25- 200918175 預備吐出動作時進行壓送的泵浦33來進行光阻劑的壓送 (9)下個基板的搬出 在下個基板S到達基板搬出位置之後,則進行該下個 基板S2的搬出動作。該動作的內容,與上述(4)的內容相 同。 (1 〇 )下個泵浦的充塡 該泵浦充塡動作,在對於下個基板S2所進行的光阻 劑吐出動作完成之瞬後開始。在該光阻劑充塡動作,與在 上述(5 )說明的光阻劑充塡動作一樣,該泵浦3 3會作動, 在將光阻劑吐出至下個基板52之瞬後在成空的內部充塡 光阻劑。在進行光阻劑之充塡的途中,將下個基板S2搬 運到搬出側載台2 8,進行該下個基板S 2的搬出動作。 以下反覆進行上述(6)〜(10)的動作。 第1 2圖是當安裝於噴嘴的泵浦爲一個的情況的塗佈 裝置的處理時序圖。 如該圖所示,泵浦爲一個時,在充塡光阻劑的期間就 不能進行預備吐出動作,藉此會讓每一枚基板的處理時間 變長。 相對的,藉由本發明的一種實施方式,由於設置有: 對於塗佈部3的噴嘴3 2分別壓送光阻劑的複數的泵浦3 3 ,所以即使藉由複數的泵浦33的其中一個泵浦充塡光阻 -26- 200918175 劑的期間,也不會浪費時間,能藉由其他泵浦3 3將光阻 劑供給到基板上。藉此,可減少每一枚基板的處理時間。 則藉由本發明的一種實施方式的構造,可使處理作業線縮 短化。 藉由本發明的一種實施方式,將複數的泵浦33配置 成:相對於噴嘴3 2互相爲大致相等距離的位置,所以能 使各個泵浦3 3與噴嘴3 2之間的光阻劑搬運路線的條件大 致相同。藉此能將光阻劑穩定吐出到基板上。 藉由本發明的一種實施方式,將複數的泵浦3 3設置 在:可自由升降地支承噴嘴32的門型框架31’所以能配 合噴嘴3 2的升降來使泵浦3 3升降。藉此,能將各個泵浦 3 3與噴嘴3 2之間的光阻劑搬運路線的狀態保持爲一定, 所以能將光阻劑穩定吐出到基板上。除此之外’讓泵浦3 3 與噴嘴3 2之間的距離很短即可完成’所以能減輕泵浦3 3 的負擔。 藉由本發明的一種實施方式,將複數的泵浦33安裝 在門型框架31的架橋構件3 1 b ’所以能以穩定狀態安裝各 泵浦33。 本發明的技術範圍並不限於上述實施方式’在不脫離 本發明主旨的範圍可以作適當變更。 針對塗佈裝置1的全體構造’在上述實施方式’雖然 是將搬運機構23配置在各載台的-Y方向側’而並不限於 此。例如,也可將搬運機構23配置在各載台的+Y方向側 。而如第1 3圖所示,也可在各載台的-γ方向側配置上述 -27- 200918175 搬運機構23(搬運機23a、真空襯墊23b、軌道23c),在 + Y方向側配置與該搬運機構23爲相同構造的搬運機構 53(搬運機53a、真空襯墊53b、軌道53c),而能以搬運機 構23與搬運機構53來搬運不同的基板。例如,如該圖所 示,在搬運機構23搬運基板S1,在搬運機構53搬運基 板S2。在該情況,則能以搬運機構23與搬運機構53來 交互搬運基板,讓生產能力提升。而在要將具有上述基板 S、S 1、S2的一半程度的面積的基板進行搬運的情況,例 如以搬運機構23與搬運機構53各保持一枚,藉由使搬運 機構2 3與搬運機構5 3朝+X方向一同行進,則能同時搬 運兩枚基板。藉由這種構造,則能讓生產能力提升。 在上述實施方式,將泵浦33配置在門型框架31的架 橋構件31b上面將該架橋構件31b在長軸方向予以三等分 的位置,而並不限於此,也可配置在其他位置。 例如,如第1 4圖所示,也可在架橋構件3 1 b上面分 別將泵浦3 3配置在該架橋構件3 1 b的長軸方向的兩端部 。也可在架橋構件31b上面分別將泵浦33配置在該架橋 構件31b的長軸方向中央部。藉由將泵浦33配置在架橋 構件31b的長軸方向中央部,則可將連接於泵浦33與噴 嘴3 2之間的配管的長度予以縮短,所以能減輕泵浦3 3 的 負擔。 在該情況,如第1 5圖所示,也可爲將兩個泵浦3 3沿 著架橋構件3 1 b的長軸方向配置的構造,如第1 6圖所示 ’也可爲將兩個泵浦33沿著基板搬運方向(架橋構件31b -28- 200918175 的短軸方向)配置的構造。在將泵浦33沿著基板搬運方 配置的構造中,尤其可將配管的長度縮短’而且也可將 個泵浦33安裝在架橋構件31b的上面以外的面部。 如第17圖所示,也可爲將兩個泵浦33安裝在門型 架31的支柱構件3 1 a的構造。在該情況,如第1 7圖所 ,也可爲在各支柱構件31a各安裝一個泵浦33的構造 雖然省略圖示,而也可爲在其中一方的支柱構件31a安 複數的泵浦3 3的構造。 如第18圖所示,也可形成爲另外設置:用來安裝 個泵浦3 3的泵浦安裝框架60的構造。如第1 8圖所示 也可將泵浦安裝框架6 0配置在相對於門型框架3 1的基 搬運方向的上游側(-X方向側),也可配置在相對於門型 架3 1的基板搬運方向的下游側(+ X方向側),可爲配置 基板搬運方向的上游側及下游側兩方的構造。 也可配置複數的噴嘴3 2,將該複數的噴嘴3 2分別 於菜浦33

Inside the nozzle 32, a flow path (not shown) through which the photoresist flows to the opening portion 3 2 a is provided. The column member 3 1 a is provided with a moving mechanism as shown in Fig. -17-200918175, and the nozzle 32 held by the bridge member 31b is movable in the Z direction by the moving mechanism. Alternatively, it may be mounted under the bridging member 31b of the portal frame 31 for the Z direction between the opening 32a of the nozzle 32, that is, the front end of the nozzle 32 and the opposing surface facing the nozzle leading end.

Among these Lipu, the high-precision quantitative pumping pump (tubephragm pump) is most suitable. (Management Unit) The structure of the management unit 4 will be described below. The management unit 4 is a portion for managing the nozzle 32 in order to limit the amount of discharge of the photoresist (liquid) discharged to the substrate S, and is provided in the substrate transport unit 2 with respect to the application unit. The -X direction side of 3 (the upstream side of the substrate conveyance direction). The management unit 4 includes a preliminary discharge mechanism 41, a dipping tank 42, a nozzle cleaning device 43, an accommodating portion 44 for accommodating these structures, and a holding member 45 for holding the accommodating portion. The holding member 45 is connected to the moving mechanism 45a. By the moving mechanism 45a, the -18-200918175 accommodating portion 44 can be moved in the X direction. The immersed door 〇 is placed so that the portion 3 2 that is disposed is washed, the pre-discharging mechanism 4 1 'dip tank 4 2, and the nozzle cleaning device 4 3 are arranged in the order toward the -X direction. The sizes of the preliminary discharge mechanism 4 1 , the stain groove 42 , and the nozzle cleaning device 43 in the Y direction are smaller than the distance between the pillar members 31 1 a of the portal frame 3 1 , and the frame 3 is formed. 1 is to access through the various parts. The preliminary discharge mechanism 4 1 is a portion that preliminarily discharges the photoresist. The preliminary discharge mechanism 4 1 is disposed closest to the nozzle 32.

The nozzle cleaning device 43 is a device for rinsing the vicinity of the opening 32a of the nozzle 32, and has a cleaning mechanism (not shown) that moves in the γ direction, and a movement (not shown) in which the cleaning mechanism moves. mechanism. The moving mechanism is placed on the -X direction side of the cleaning mechanism. The nozzle cleaning device 43 is provided with a moving mechanism, and has a larger dimension in the X direction than the preliminary discharge mechanism 4 1 and the immersion tank 42. When the nozzle cleaning device 43 is disposed close to the position of the nozzle 32 (+X direction side), the other portion is placed at a position farther from the nozzle 3 2 (the -X direction side). In this case, when the nozzle 3 2 is connected to other portions in the housing 44, it is necessary to pass the moving mechanism, thereby making the moving distance of the nozzle longer. The nozzle cleaning device 43 of the present embodiment is provided at a position closer to the -X direction than the preliminary discharge mechanism 41 and the immersion tank 42, and the moving mechanism of the nozzle cleaning device 43 is provided in the cleaner of the nozzle cleaning device 43. The mechanism is further on the -X direction side, so the nozzle 32 is not configured by the moving mechanism -19-200918175 to minimize the moving distance of the nozzle 32. Of course, the arrangement of the preliminary discharge mechanism 41, the immersion tank 42, and the nozzle cleaning device 43 is not limited to the arrangement mode of the present embodiment. Other arrangements (operation of the coating device) may be used. The operation of the coating device 1 of the structure. Fig. 5 is a timing chart showing the operation of the coating device 1. As shown in Fig. 5, in the coating device 1, each operation of substrate loading, photoresist application, substrate unloading, preliminary discharge, and photoresist filling (pump charging) is performed. The operation of applying a photoresist to the substrate S will be described below. Fig. 6 to Fig. 9 are plan views showing respective operations of substrate loading, photoresist application, and substrate unloading of the coating apparatus 1. The substrate S is carried into the substrate loading area 20, the substrate S is floated and transported, and a photoresist is applied to the coating processing region 21 to carry out the substrate S to which the photoresist has been applied from the substrate. 22 moved out. 7 to 9 show the outline of the door frame 31 only by a broken line, and it is easy to judge the configuration of the nozzle 32 and the processing stage 27. The detailed operation of each part will be described below. The coating device 1 is placed on standby before the substrate is carried into the substrate loading area 20. Specifically, the transporter 23a is disposed on the -Y direction side of the substrate loading position of the loading-side stage 25, and the height position of the vacuum pad 23b is positioned at the floating height position of the substrate, and from the loading-side stage 25 The air ejection hole 25a, the air ejection hole 27a of the processing stage 27, the air suction hole 27b, and the air ejection hole 28a of the carry-out side stage 28 respectively suck the air or -20-200918175 to supply air. The state in which the substrate is floated on the surface of each stage. The photoresist is pre-charged into the pump 3 3 . Specifically, the photoresist which is required for the preliminary discharge operation and the component required for the optical cloth after the preliminary discharge operation is charged in the two pumps 3 (1), and the substrate is carried in the state, for example, by no figure. When the substrate S is transported to the substrate loading position from the outside, the member 2 6 a moves in the + Z direction, and the lift pin 2 6 b protrudes from the lift pin 25b to the stage surface 25c. . On the other hand, the transfer operation of the substrate S is performed by the lift pins 26b. On the other hand, the positioning member protrudes from the aligning device 25d on the stage surface 25c. After receiving the substrate S, the elevating member 26 6a is lowered to accommodate 2 6 b in the elevating pin exit hole 2 5 b. At this time, since the air layer is formed on the carrier 25c, the substrate S is maintained in a state where the stage surface 25c is floated by the air. When the substrate s reaches the air layer, the positioning of the substrate S is performed by the calibration device 25d, and the vacuum liner of the carrier 23a disposed at the -Y direction side of the entry position is adsorbed to the -Y direction of the substrate s. Side end. Fig. 7 shows the state of the end portion of the substrate S on the -Y direction side. (2) Pre-discharge Before the application of the photoresist to the substrate S, the application portion 3 maintains the preliminary discharge operation of the discharge state of the nozzle 3 2 . To this extent, the resist is applied. Figure 6: Lifting the hole and lifting the hole. The surface of the lifting pin table is the opposite surface. The substrate is moved. 23b is actually sucked and ready for use. -21 - 200918175 The operation is performed at the same time as the loading of the substrate. First, as shown in Fig. 10, the door frame 31 is moved to the position of the management unit 4 in the -X direction by the moving mechanism 31c (shown in Fig. 4). After the door frame 3 1 is moved to the position of the management unit 4, the position of the door frame 31 is adjusted to connect the nozzle 32 to the nozzle cleaning device 43. In the nozzle cleaning device 43, a cleaning liquid such as a diluent is discharged toward the vicinity of the opening 32a of the nozzle 32, and if necessary, nitrogen gas and a diluent are simultaneously discharged to the opening portion 3 2 a of the nozzle 3 2 while The cleaning mechanism (not shown) is scanned toward the long axis direction of the nozzle 3 2, and the nozzle 32 is washed. After the nozzle 3 2 is cleaned, the nozzle 3 2 is connected to the preliminary discharge unit 41. In the preliminary discharge unit 41, the distance between the opening 32a and the preliminary discharge surface is measured, and the opening 32 2a of the nozzle 3 2 is moved to a predetermined position in the Z direction, and the nozzle 32 is oriented in the -X direction. When moving, the photoresist is prepared to be discharged from the opening 3 2a. In the preliminary discharge operation, among the two pumps 33 provided, one of the pumps 3 3 filled with the photoresist presses the internal photoresist to the flow path of the nozzle 3 2 . After the preliminary ejection operation is performed, the portal frame 3 1 is returned to the original position, and when the next substrate S is to be transported, as shown in Fig. 11, the nozzle 3 2 is moved to the Z direction by the moving mechanism 3 1 b. The intended location. Alternatively, if necessary, for example, the management unit 4 is connected every predetermined number of times, the nozzle 3 2 is brought into the dipping tank 42. In the immersion tank 42, the nozzle 32 is prevented from drying by exposing the opening 32a of the nozzle 32 to a vapor atmosphere of a solvent (diluent) stored in the immersion tank 42. -22-200918175 (Coating) After the end portion on the -Y direction side of the substrate s is sucked by the vacuum pad 23b, the carrier 23a is moved along the rail 23c. Since the substrate S is in a floating state, even if the driving force of the conveyor 2 3 a is small, the substrate s can smoothly move along the rail 23 C. When the substrate S moves from the loading-side stage 25 toward the processing stage 27, the amount of floating of the substrate on the processing stage 27 is ΙΟΟμηη, and preferably 50 μm or less. When the leading end of the substrate S in the conveyance direction reaches the position of the opening 32a of the nozzle 32, the photoresist is applied onto the substrate S. In the photoresist application operation, among the two pumps 33 provided, the pump 3 3 that performs the pressure feed in the preliminary discharge operation again presses the photoresist in the pump 3 3 to the nozzle 3 2 . Flow path. As shown in Fig. 7, the pressure-transmitted photoresist is discharged from the opening portion 3 2a (shown in Fig. 4) toward the substrate S. The discharge operation of the photoresist is performed by fixing the position of the nozzle 32 and transporting the substrate S by the transporter 23a. As the substrate S moves, the photoresist film R is applied onto the substrate S as shown in Fig. 8. The resist film R is formed in a predetermined region of the substrate S by passing the substrate S through the lower surface of the opening 32a of the photoresist. The substrate S on which the photoresist film R is formed is transported toward the carry-out side stage 28 by the transporter 23a. In the state in which the carry-out side stage 2 8 is floated with respect to the stage surface 28C, the substrate S is transported to the substrate carry-out position as shown in Fig. 9. (4) Substrate carry-out -23- 200918175 When the substrate S reaches the substrate carry-out position, the suction of the vacuum liner 23b is released. After the adsorption of the substrate S is released, the transporter 23a returns to the substrate loading position of the loading-side stage 25. After the adsorption is released, the elevating member 29a of the elevating mechanism 29 is moved in the +Z direction. As the elevating member 29a moves, the elevating pin 29b protrudes from the elevating pin ejecting hole 28b toward the rear surface of the substrate S, and the substrate S is lifted by the elevating pin 2 9 b. In this state, for example, the external transport arm provided at the +X direction side of the carry-out side stage 28 is connected to the carry-out side stage 28 to receive the substrate S. The substrate S is carried out in this manner. (5) Pump charging The pump charging action starts after the completion of the discharge of the photoresist. Immediately after the photoresist is ejected, the photoresist holding portion 3 3 a of the pump 3 3 used for the discharge of the photoresist is emptied. When the photoresist is charged, the pump 3 3 will act to fill the photoresist into the empty interior. In the middle of charging the photoresist, the substrate S is transported to the carry-out side stage 2, and the substrate S is carried out. (6) The loading of the next substrate (hereinafter referred to as "next substrate") S2 of the substrate is performed at substantially the same time as the start time of the substrate S. In the loading operation, similarly to the loading operation of the substrate S, the lower substrate s 2 is received by the lift pins 26b, and then floated and held on the carry-side stage 25 to perform a calibration operation. When the substrate S is carried out, the carrier 23a that has returned to the substrate loading position at -24-200918175 returns to the substrate loading position before the calibration operation of the next substrate S2 is completed. The next substrate S2 is adsorbed by the suction pad 2 3 b of the conveyor 2 3 a which is returned to the substrate loading position. (7) Pre-discharge of the next substrate After the substrate transfer and the photoresist application operation described in the above (3) are completed, the preliminary discharge operation for discharging the photoresist to the next substrate S 2 is performed. The content of the preliminary discharge operation is the same as that described in the above (2). In the preliminary discharge operation, the pump 33 is different from the pump 33 which is pumped in the above (2) and (3) by the two pumps 33. When the preparatory discharge operation of the next substrate is started, the pump 3 3 that has been pressure-fed in the above (2) and (3) is in a state in which the photoresist charging operation is performed. The timing at which the timing of completion of the loading operation of the next substrate S2 is substantially the same. The preparatory discharge operation of the next substrate is also completed. Then, the next substrate is prepared for the discharge operation, and is carried out together with the carry-out operation of the substrate S, the loading operation of the next substrate S2, and the photoresist filling operation. (8) Application of the next substrate After the next substrate S2 is carried into the carry-in stage 25 and adsorbed by the suction pad 23b, the next substrate S2 is transported to the process stage 27. After the next substrate S2 is transported to the processing stage 27, a photoresist is applied to the next substrate S2. The contents of the transport operation and the coating operation for the next substrate S 2 are the same as those described in the above (2) and (3). In the coating operation, the pumping of the photoresist is performed by the pump 33 that is pressure-fed during the preparatory discharge operation of the above-mentioned (7) -25 to 200918175 among the two pumps 33 (9) After the next substrate is carried out and the next substrate S reaches the substrate carry-out position, the next substrate S2 is carried out. The content of this action is the same as that of the above (4). (1 〇) Charge of the next pump This pump charge operation starts after the completion of the photoresist discharge operation for the next substrate S2. In the charging operation of the photoresist, the pump 3 3 is actuated as in the charging operation of the photoresist described in the above (5), and is emptied immediately after the photoresist is discharged to the next substrate 52. The interior is filled with a photoresist. While the photoresist is being charged, the next substrate S2 is transported to the carry-out side stage 2, and the next substrate S2 is carried out. The above operations (6) to (10) are repeated as follows. Fig. 12 is a process timing chart of the coating device in the case where the pump installed in the nozzle is one. As shown in the figure, when the pump is one, the preliminary discharge operation cannot be performed while the photoresist is being charged, and the processing time per substrate is made longer. In contrast, according to an embodiment of the present invention, since a plurality of pumps 3 3 for respectively applying a photoresist to the nozzles 3 2 of the coating portion 3 are provided, even one of the plurality of pumps 33 is provided. During the pumping of the photoresist -26- 200918175, no time is wasted, and the photoresist can be supplied to the substrate by other pumps 3 3 . Thereby, the processing time of each substrate can be reduced. By the configuration of an embodiment of the present invention, the processing line can be shortened. According to one embodiment of the present invention, the plurality of pumps 33 are disposed at positions substantially equal to each other with respect to the nozzles 3 2, so that the photoresist transfer route between the respective pumps 3 3 and the nozzles 3 2 can be made. The conditions are roughly the same. Thereby, the photoresist can be stably discharged onto the substrate. According to one embodiment of the present invention, the plurality of pumps 3 3 are provided in the door frame 31' which can support the nozzle 32 so as to be freely movable and lowered, so that the pump 3 3 can be moved up and down to raise and lower the pump 3 3 . Thereby, the state of the photoresist transport path between each of the pump 3 3 and the nozzle 3 2 can be kept constant, so that the photoresist can be stably discharged onto the substrate. In addition to this, 'the distance between the pump 3 3 and the nozzle 3 2 is short enough to be completed', so that the burden of the pump 3 3 can be alleviated. According to an embodiment of the present invention, the plurality of pumps 33 are mounted to the bridging members 3 1 b ' of the portal frame 31 so that the respective pumps 33 can be mounted in a stable state. The technical scope of the present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the scope of the present invention. In the above-described embodiment, the entire configuration of the coating apparatus 1 is such that the transport mechanism 23 is disposed on the -Y direction side of each stage, and is not limited thereto. For example, the transport mechanism 23 may be disposed on the +Y direction side of each stage. Further, as shown in Fig. 3, the transport mechanism 23 (transporter 23a, vacuum pad 23b, track 23c) of the above -27-200918175 may be disposed on the -γ direction side of each stage, and arranged in the +Y direction side. The transport mechanism 23 is a transport mechanism 53 (a transporter 53a, a vacuum cushion 53b, and a rail 53c) having the same structure, and the transport mechanism 23 and the transport mechanism 53 can transport different substrates. For example, as shown in the figure, the substrate S1 is transported by the transport mechanism 23, and the substrate S2 is transported by the transport mechanism 53. In this case, the substrate can be transported by the transport mechanism 23 and the transport mechanism 53 to increase the productivity. On the other hand, when the substrate having the area of about half of the substrates S, S1, and S2 is to be transported, for example, the transport mechanism 23 and the transport mechanism 53 are each held one by one, and the transport mechanism 2 and the transport mechanism 5 are moved. 3 When you walk in the +X direction, you can carry two substrates at the same time. With this configuration, productivity can be improved. In the above embodiment, the pump 33 is disposed on the upper surface of the bridge member 31b of the portal frame 31, and the bridge member 31b is equally divided in the longitudinal direction. The present invention is not limited thereto, and may be disposed at another position. For example, as shown in Fig. 14, the pump 3 3 may be disposed on both ends of the bridging member 3 1 b in the longitudinal direction of the bridging member 3 1 b. The pump 33 may be disposed on the upper portion of the bridge member 31b in the longitudinal direction of the bridge member 31b. By arranging the pump 33 in the central portion in the longitudinal direction of the bridge member 31b, the length of the pipe connected between the pump 33 and the nozzle 3 2 can be shortened, so that the load on the pump 3 3 can be reduced. In this case, as shown in Fig. 15, a configuration may be adopted in which the two pumps 3 3 are arranged along the longitudinal direction of the bridge member 3 1 b, as shown in Fig. 16. The configurations of the pumps 33 are arranged along the substrate conveyance direction (the short-axis direction of the bridge members 31b-28-200918175). In the configuration in which the pump 33 is disposed along the substrate conveyance side, in particular, the length of the pipe can be shortened' and the pumps 33 can be attached to the face other than the upper surface of the bridge member 31b. As shown in Fig. 17, a structure in which the two pumps 33 are attached to the strut members 31a of the portal frame 31 may be employed. In this case, as shown in Fig. 17, a structure in which one pump 33 is attached to each of the pillar members 31a may be a pump 3 3 in which one of the pillar members 31a is plural. Construction. As shown in Fig. 18, it is also possible to form a configuration in which the pump mounting frame 60 for mounting the pump 3 3 is additionally provided. The pump mounting frame 60 may be disposed on the upstream side (the -X direction side) with respect to the base conveyance direction of the portal frame 3 1 as shown in FIG. 18, or may be disposed on the door frame 3 1 with respect to the portal frame 3 1 In the downstream side (+X direction side) of the board conveyance direction, it is possible to arrange both the upstream side and the downstream side in the board conveyance direction. A plurality of nozzles 3 2 may also be disposed, and the plurality of nozzles 3 2 may be disposed separately from the kitchen 33. In Fig. 19, an example in which each of the nozzles 3 2 is disposed on the upstream side and the side of the substrate in the substrate conveyance direction of the door frame 3 1 is shown. The long axis directions of the two nozzles 3 2 are arranged to intersect perpendicularly in the substrate transport direction. With this configuration, different nozzles 32 can be used interchangeably for each of the substrates. Therefore, while the coating operation is performed by one of the nozzles 32, the other nozzle 32 can be filled with the photoresist. By having a plurality of nozzles, different types of photoresist can be applied interactively. Alternatively, the plurality of management units 4 may be provided. The two frames are shown in the two frames. The frame is placed in the opposite direction, and the configuration in Fig. 19 in Fig. 19 shows that each nozzle 32 is disposed upstream of the substrate carrying direction of the portal frame 31. Examples of the side and the downstream side are not limited thereto, and a plurality of door frames 3 1 may be disposed, and the long axis direction of each of the nozzles 32 is disposed along the substrate with respect to the plurality of door frames 31 The direction in which the conveying directions intersect perpendicularly. In this case, a plurality of management units 4 can be provided. By this configuration, 'for each of the substrates' can be used interchangeably: the nozzles 3 2 provided at the plurality of gate frames 31 that are independently controlled, so that the coating operation is performed by one of the nozzles 32' The photoresist 32 can be filled on the other side of the nozzle 32. By having a plurality of nozzles 3 2, different kinds of photoresists can be alternately applied. In the structure of Fig. 19, by allowing each nozzle 3 2 to move independently, the preliminary discharge operation can be performed after the photoresist is filled. Thereby, the processing line can be shortened. In the case where the respective nozzles 32 independently perform the preliminary discharge operation, a plurality of management units 4 may be provided. In this case, it is preferable to arrange the nozzle 32 and the pump 3 3 connected to the nozzle 32 integrally. As such a configuration, for example, a structure in which the pump 33 is directly attached to the nozzle 32, a structure in which the nozzle 32 is integrally attached to the moving member, and a configuration in which the pump 3 3 is attached to the moving member can be cited. Thereby, the nozzle 3 2 and the pump 3 3 are integrally moved, so that the position of both of them can be prevented from changing due to the movement of the nozzle 32. Thereby, the environment of the resist conveyance path between the nozzle 3 2 and the pump 3 3 can be maintained, so that the photoresist discharge of the nozzle 32 can be stabilized. In the above-described respective configurations 'as the plurality of pumps 33, for example, an example in which two pumps 3 3 are disposed is described, and the present invention is not limited thereto. For example, three pumps 33 on -30-200918175 may be provided. In the above embodiment, one pump 33 is provided for one nozzle 32, and is not limited thereto. For example, two pumps 33 may be used for the ~ nozzles 32. [Industrial Applicability] The present invention provides a coating apparatus and a coating method capable of shortening a processing line, and is very useful industrially.
