批次處理部4配置於第一介面部3的X軸正方向側。亦即,搬入搬出部2、第一介面部3及批次處理部4,係以此順序從X軸負方向側往X軸正方向側配置。批次處理部係將以第一間距P1包含複數片(例如50片或是100片)基板W的基板批L整批進行處理。一個基板批L例如係以M個基板匣盒C的基板W構成。M為2以上的自然數。M可為與N相同的自然數,亦可為與N不同的自然數。批次處理部4包含:化學藥液槽41、沖洗液槽42、第一搬運裝置43、處理具44及驅動裝置45。
化學藥液槽41及沖洗液槽42係沿著X軸方向配置。例如,化學藥液槽41及沖洗液槽42係依此順序從X軸正方向側往X軸負方向側排列。又,亦可將化學藥液槽41及沖洗液槽42統稱為處理槽。化學藥液槽41及沖洗液槽42的數並不限定於圖1的數量。例如,化學藥液槽41及沖洗液槽42在圖1中為一組,但亦可為複數組。
化學藥液槽41係儲存浸漬基板批L的化學藥液。化學藥液例如為磷酸水溶液(H
3PO
4)。磷酸水溶液係在矽氧化物膜與氮化矽膜中,選擇性地蝕刻氮化矽膜並將其去除。化學藥液並不限定於磷酸水溶液。例如亦可為DHF(稀氫氟酸)、BHF(氟酸與氟化銨的混合液)、稀硫酸、SPM(硫酸與過氧化氫與水的混合液)、SC1(氨與過氧化氫與水的混合液)、SC2(鹽酸與過氧化氫與水的混合液)、TMAH(四甲基氫氧化銨與水的混合液)、電鍍液等。化學藥液亦可為剝離處理用或是電鍍處理用。化學藥液的數量並未特別限定,亦可為複數。

處理具44係從第一搬運臂43b承接基板批L並加以固持。處理具44係在Y軸方向上以第一間距P1固持複數片基板W,並將複數片基板W分別鉛直地固持。
驅動裝置45係使處理具44在X軸方向及Z軸方向上移動。處理具44係使基板批L浸漬於儲存在化學藥液槽41的化學藥液,接著,使基板批L浸漬於儲存在沖洗液槽42的第一沖洗液,其後,將基板批L傳遞至第一搬運裝置43。
處理具44與驅動裝置45之單元的數量,在本實施態樣為一個,但亦可為複數。後者的情況,一個單元係使基板批L浸漬於儲存在化學藥液槽41的化學藥液,另一個單元係使基板批L浸漬於儲存在沖洗液槽42的第一沖洗液。此情況下,驅動裝置45亦可只要使處理具44在Z軸方向上移動即可,而不需使處理具44在X軸方向上移動。
第二介面部5配置於批次處理部4的Y軸正方向側。第二介面部5係在其與批次處理部4及單片處理部6之間搬運基板W。第二介面部5包含:浸漬槽51、第二搬運裝置52、第三搬運裝置53及第二傳遞台54。
浸漬槽51配置於第一搬運臂43b的移動範圍外。例如,浸漬槽51配置於相對於處理槽往Y軸正方向側錯開的位置。浸漬槽51儲存浸漬基板批L的第二沖洗液。第二沖洗液例如為超純水(去離子水)。基板W在藉由第三搬運裝置53從第二沖洗液拉起前,係固持在第二沖洗液中。由於基板W存在於比第二沖洗液之液面更下方,故第二沖洗液的表面張力不會作用於基板W,而可防止基板W的不規則性圖案之崩塌。
第二搬運裝置52包含:Y軸驅動裝置52a、Z軸驅動裝置52b及第二搬運臂52c。
Y軸驅動裝置52a配置於第二介面部5的X軸正方向側。Y軸驅動裝置52a係從第二介面部5往批次處理部4沿著水平方向(Y軸方向)而延伸。Y軸驅動裝置52a係使Z軸驅動裝置52b及第二搬運臂52c在Y軸方向上移動。Y軸驅動裝置52a亦可包含滾珠螺桿。
Z軸驅動裝置52b係可移動地安裝於Y軸驅動裝置52a。Z軸驅動裝置52b係使第二搬運臂52c在Z軸方向上移動。Z軸驅動裝置52b亦可包含滾珠螺桿。
第二搬運臂52c係可移動地安裝於Z軸驅動裝置52b。第二搬運臂52c係從第一搬運臂43b承接基板批L並加以固持。第二搬運臂52c係在Y軸方向上以第一間距P1固持複數片基板W,並將複數片基板W分別鉛直地固持。第二搬運臂52c係藉由Y軸驅動裝置52a及Z軸驅動裝置52b而在Y軸方向及Z軸方向上移動。第二搬運臂52c可在包含傳遞位置、浸漬位置及待命位置的複數位置移動。
傳遞位置係在第一搬運臂43b及第二搬運臂52c之間進行基板批L之傳遞的位置。傳遞位置係在Y軸負方向側且Z軸正方向側的位置。
浸漬位置係使基板批L浸漬於浸漬槽51的位置。浸漬位置係在比傳遞位置更Y軸正方向側且Z軸負方向側的位置。
待命位置係在未進行基板批L之傳遞及對浸漬槽51浸漬基板批L時,第二搬運臂52c所待命的位置。待命位置係在傳遞位置正下方(Z軸負方向側),且不會妨礙第一搬運臂43b之移動的位置。此情況下,由於第二搬運臂52c僅藉由往上方(Z軸正方向側)移動便可移動至傳遞位置,故可提高處理量。待命位置亦可與浸漬位置相同位置。此情況下,可防止因第一搬運裝置43動作所產生的微粒附著於第二搬運臂52c。待命位置亦可在浸漬位置正上方(Z軸正方向側)的位置。如此,藉由將待命位置設於與傳遞位置不同的位置,可防止第一搬運臂43b與第二搬運臂52c的接觸。
在第一搬運裝置43動作期間,此第二搬運裝置52係使第二搬運臂52c移動至浸漬位置或是待命位置。藉此,可防止第一搬運臂43b與第二搬運臂52c的接觸。
第三搬運裝置53係由多軸(例如6軸)機械臂構成,並於其前端具有第三搬運臂53a。第三搬運臂53a具有可固持一片基板W的固持爪(未圖示)。第三搬運臂53a可在藉由固持爪固持住基板W的狀態下,於三維空間內採取任意位置及姿態。第三搬運裝置53係在位於浸漬位置之第二搬運臂52c及第二傳遞台54之間搬運基板W。此時,由於浸漬槽51配置於第一搬運臂43b的移動範圍外,故第一搬運臂43b與第三搬運臂53a不會互相干擾。藉此,可使第一搬運裝置43及第三搬運裝置53中的其中一者不受另一者之動作狀態影響而獨立動作。因此,由於可在任意時間點使第一搬運裝置43及第三搬運裝置53動作,故可縮短基板W之搬運所需要的時間。其結果,可提高基板處理系統1的生產率。
第二傳遞台54鄰接於單片處理部6,並配置於第二介面部5的X軸負方向側。第二傳遞台54係從第三搬運裝置53承接基板W,並在傳遞至單片處理部6前暫時保管。亦即,在第二傳遞台54中,係載置從浸漬槽51取出的基板W。載置於第二傳遞台54的基板W,較佳係例如表面為經第二沖洗液潤濕的狀態。此情況下,第二沖洗液的表面張力不會作用於基板W,可抑制基板W的不規則性圖案之崩塌。在第二傳遞台54中,係載複數片(例如2片)基板W。
單片處理部6配置於第二介面部5的X軸負方向側,且配置於搬入搬出部2、第一介面部3及批次處理部4的Y軸正方向側。單片處理部6係將基板W逐一進行處理。單片處理部6包含:第四搬運裝置61、液體處理裝置62及乾燥裝置63。
第四搬運裝置61包含導軌61a及第四搬運臂61b。導軌61a配置於單片處理部6的Y軸負方向側。導軌61a係在單片處理部6中沿著水平方向(X軸方向)而延伸。第四搬運臂61b係沿著導軌61a而在水平方向(X軸方向)及鉛直方向上移動,並繞著鉛直軸旋轉。第四搬運臂61b係在第二傳遞台54、液體處理裝置62、乾燥裝置63及第一傳遞台33之間搬運基板W。第四搬運臂61b的數量可為一個亦可為複數,後者的情況,第四搬運裝置61係將複數片(例如5片)基板W整批搬運。
液體處理裝置62配置於單片處理部6的X軸正方向側且Y軸正方向側。液體處理裝置62為單片型,且以處理液將基板W逐一處理。液體處理裝置62在鉛直方向(Z軸方向)上配置成多段(例如3段)。藉此,可同時以處理液處理複數片基板W。處理液亦可為複數種,例如,亦可為超純水等純水及表面張力低於純水的乾燥液。乾燥液例如亦可為IPA(異丙醇)等醇。
乾燥裝置63相對於液體處理裝置62係鄰接配置於X軸負方向側。此情況下,單片處理部6的Y軸正方向側之端面,可配置成與第二介面部5的Y軸正方向側之端面齊平或是大致齊平。因此,由於幾乎不會產生無效區域,故可使基板處理系統1的佔地面積較小。相對於此,若乾燥裝置63相對於液體處理裝置62係鄰接配置於Y軸正方向側,則單片處理部6的Y軸正方向側之端面,會比第二介面部5的Y軸正方向側之端面更突出,而產生無效區域。乾燥裝置63為單片型,並以超臨界流體將基板W逐一乾燥。乾燥裝置63係在鉛直方向上配置成多段(例如3段)。藉此,可使複數片基板W同時乾燥。
液體處理裝置62及乾燥裝置63兩者亦可均非為單片型,亦可液體處理裝置62為單片型,而乾燥裝置63為批次型。乾燥裝置63亦可藉由超臨界流體將複數片基板W整批乾燥。在乾燥裝置63中整批處理的基板W之片數,與在液體處理裝置62中整批處理的基板W之片數相比亦可相等或較多,亦可較少。液體處理裝置62及乾燥裝置63以外的裝置亦可配置於單片處理部6。
控制裝置9例如為電腦,並包含CPU(Central Processing Unit,中央處理單元)91及記憶體等記錄媒體92。在記錄媒體92中,儲存有控制基板處理系統1中執行的各種處理之程式。控制裝置9係藉由使CPU91執行儲存於記錄媒體92的程式,而控制基板處理系統1的動作。控制裝置9包含輸入介面93及輸出介面94。控制裝置9係以輸入介面93接收來自外部的訊號,並以輸出介面94將訊號傳輸至外部。
上述程式例如儲存於電腦可讀取記錄媒體,並從該記錄媒體安裝至控制裝置9的記錄媒體92。作為電腦可讀取記錄媒體,例如可列舉:硬碟(HD)、軟性磁碟(FD)、光碟(CD)、磁光碟(MO)及記憶卡等。又,程式亦可經由網際網路從伺服器下載,並安裝至控制裝置9的記錄媒體92。
控制裝置9係基於與搬入搬入搬出部2之基板匣盒C相關的資訊,而控制基板移載裝置31,以將基板匣盒C所收納的複數片基板W搬運至第一傳遞台33及基板批形成部32的其中任一者。該資訊亦可包含基板類別。例如,控制裝置9在基板類別為製品基板的情況下,係控制基板移載裝置31將基板匣盒C所收納的基板W搬運至基板批形成部32。例如,控制裝置9在基板類別為擋片基板的情況下,係控制基板移載裝置31將基板匣盒C所收納的基板W搬運至第一傳遞台33。
以上所說明的依實施態樣之基板處理系統包含:搬入搬出部2、第一介面部3、批次處理部4、第二介面部5及單片處理部6。第一介面部3,將位於搬入搬出部2之基板匣盒C所收納的基板W,在其與單片處理部6及批次處理部4之間進行分配。分配至單片處理部6的基板W,係在單片處理部6中進行單片處理。分配至批次處理部4的基板W,係在批次處理部4中進行批次處理。第二介面部5係將施予過批次處理的基板W搬運至單片處理部6。搬運至單片處理部6的基板W,係在單片處理部6中進行單片處理。如此,可對位於搬入搬出部2之基板匣盒C所收納的基板W並行實施包含批次處理與單片處理的複合處理,及未經由批次處理部4的單片處理。
(基板處理系統的動作)
參照圖2~圖4,說明依實施態樣之基板處理系統1的動作,亦即基板處理方法。圖2所示的處理係在藉由控制裝置9所進行之控制下實施。
首先,基板匣盒C在收納有複數片基板W的狀態下,被搬入搬入搬出部2,並載置於載入埠21。在基板匣盒C的內部,基板W係被水平地固持,並在鉛直方向上以第二間距P2(P2=N×P1)受到固持。N為2以上的自然數,在本實施態樣中為2但亦可為3以上。
接著,基板匣盒搬運裝置24將基板匣盒C從載入埠21搬運至裝載器23(圖3的箭頭F1,圖4的箭頭G1)。當將基板匣盒C搬運至裝載器23後,藉由蓋體開閉機構開啟基板匣盒C的蓋體。
接著,控制裝置9控制基板處理系統1之各部,以進行圖2所示的處理。控制裝置9控制基板處理系統1之各部,在每次將基板匣盒C載置於裝載器23時,進行圖2所示的處理。
首先,在將基板匣盒C搬運至裝載器23後,控制裝置9係基於與該基板匣盒C相關之資訊,對該基板匣盒C所收納的複數片基板W,判斷進行複合處理及單片處理中的哪一者(圖2的S101)。
在圖2的S101中判斷為進行複合處理時,控制裝置9係控制基板處理系統1之各部,以將基板匣盒C所收納的基板W搬運至批次處理部4(圖2的S102)。具體而言,基板移載裝置31會承接基板匣盒C所收納的基板W,並搬運至基板批形成部32(圖3的箭頭F2)。接著,基板批形成部32係以第一間距P1(P1=P2/N)固持複數片基板W,並形成基板批L。一個基板批L例如由M個基板匣盒C的基板W構成。由於基板W的間距從第二間距P2變成較窄的第一間距P1,故可增加整批處理的基板W之片數。接著,第一搬運裝置43會從基板批形成部32承接基板批L,並搬運至處理具44(圖3的箭頭F3)。
接著,處理具44會從化學藥液槽41的上方下降,並將基板批L浸漬於化學藥液,以進行化學藥液處理(圖2的S103)。其後,處理具44會從化學藥液上升以將基板批L拉起,接著在水平方向(X軸負方向側)上往沖洗液槽42的上方移動(圖3的箭頭F4)。
接著,處理具44會從沖洗液槽42的上方下降,並將基板批L浸漬於第一沖洗液,以進行沖洗液體處理(圖2的S103)。其後,處理具44會從第一沖洗液上升以將基板批L拉起。接著,第一搬運裝置43會從處理具44承接基板批L,並傳遞至第二搬運裝置52。
接著,第二搬運裝置52的第二搬運臂52c係在水平方向(Y軸正方向側)上移動,並從浸漬槽51的上方下降,以使基板批L浸漬於第二沖洗液(圖2的S104,圖3的箭頭F5)。基板批L的複數基板W在藉由第三搬運裝置53從第二沖洗液拉起前,係固持在第二沖洗液中。由於基板W存在於比第二沖洗液之液面更下方,故第二沖洗液的表面張力不會作用於基板W,而可防止基板W的不規則性圖案之崩塌。
接著,第三搬運裝置53係將在第二沖洗液中藉由第二搬運臂52c固持之基板批L的基板W,搬運至第二傳遞台54(圖3的箭頭F6)。第三搬運裝置53係將基板W逐一搬運至第二傳遞台54。
接著,第四搬運裝置61會從第二傳遞台54承接基板W,並搬運至液體處理裝置62(圖3的箭頭F7)。
接著,液體處理裝置62係以液體將基板W逐一進行處理(圖2的S105)。液體亦可為複數種,例如宜為超純水等純水及表面張力低於純水的乾燥液。乾燥液例如宜為IPA等醇。液體處理裝置62係對基板W的頂面,依序供給純水及乾燥液,並形成乾燥液的液體膜。
接著,第四搬運裝置61會從液體處理裝置62承接基板W,並以使乾燥液之液體膜朝上的方式水平地固持基板W。第四搬運裝置61係將基板W從液體處理裝置62搬運至乾燥裝置63(圖3的箭頭F8)。
接著,乾燥裝置63係以超臨界流體將基板W逐一進行乾燥(圖2的S105)。將乾燥液替換為超臨界流體,而可抑制因乾燥液之表面張力而造成的基板W的不規則性圖案之崩塌。由於超臨界流體需要耐壓容器,因此為了使耐壓容器小型化故進行單片處理,而非進行批次處理。
又,乾燥裝置63在本實施態樣中為單片型,但如上所述,亦可為基板批型。基板批型的乾燥裝置63係以超臨界流體將形成有液體膜的複數片基板W整批進行乾燥。相對於單片型的乾燥裝置63具有一個固持基板W的搬運臂,基板批型的乾燥裝置63則具有複數搬運臂。
又,本實施態樣的乾燥裝置63係以超臨界流體將基板W乾燥,但乾燥的方式並未特別限定。乾燥方式只要能抑制基板W的不規則性圖案之崩塌即可,例如亦可為旋轉乾燥、掃描乾燥,或是撥水乾燥等。旋轉乾燥係使基板W旋轉,並藉由離心力將液體膜從基板W甩下。掃描乾燥係一邊使乾燥液的供給位置從基板W的中心往基板W的外周移動,一邊使基板W旋轉,並藉由離心力將液體膜從基板W甩下。掃描乾燥亦可進一步使N
2氣體等乾燥氣體的供給位置,以追隨乾燥液的供給位置之方式,從基板W的中心往基板W的外周移動。
接著,第四搬運裝置61會從乾燥裝置63承接基板W,並搬運至第一傳遞台33(圖3的箭頭F9)。
接著,基板移載裝置31會從第一傳遞台33承接基板W,並收納至載置於裝載器23的基板匣盒C內(圖2的S106,圖3的箭頭F10)。
接著,基板匣盒搬運裝置24會將基板匣盒C從裝載器23搬運至載入埠21(圖3的箭頭F11)。搬運至載入埠21的基板匣盒C係在收納有複數片基板W的狀態下,從搬入搬出部2搬出。又,基板匣盒搬運裝置24亦可將基板匣盒C從裝載器23搬運至暫存架22,並在暫存架22中暫時保管。
在圖2的S101中,判斷為進行單片處理時,控制裝置9係控制基板處理系統1之各部,將基板匣盒C所收納的基板W搬運至單片處理部6(圖2的S107)。具體而言,基板移載裝置31會承接基板匣盒C所收納的基板W,並搬運至第一傳遞台33(圖4的箭頭G2)。接著,第四搬運裝置61會從第一傳遞台33承接基板W,並搬運至液體處理裝置62(圖4的箭頭G3)。
接著,與圖2的S105相同,液體處理裝置62會以液體將基板W逐一進行處理,接著乾燥裝置63會以超臨界流體將基板W逐一進行乾燥(圖2的S108,圖4的箭頭G4)。
接著,第四搬運裝置61會從乾燥裝置63承接基板W,並搬運至第一傳遞台33(圖4的箭頭G5)。
接著,基板移載裝置31會從第一傳遞台33承接基板W,並收納至載置於裝載器23的基板匣盒C內(圖2的S109,圖4的箭頭G6)。
接著,基板匣盒搬運裝置24會將基板匣盒C從裝載器23搬運至載入埠21(圖4的箭頭G7)。搬運至載入埠21的基板匣盒C係在收納有複數片基板W的狀態下,從搬入搬出部2搬出。又,基板匣盒搬運裝置24亦可將基板匣盒C從裝載器23搬運至暫存架22,並在暫存架22中暫時保管。
在以上所說明的依實施態樣之基板處理方法中,例如當將複合處理之對象亦即第一基板匣盒搬運至裝載器23時,第一介面部3會將第一基板匣盒所收納的基板W分配至批次處理部4。
分配至批次處理部4的基板W,係在批次處理部4中進行批次處理。第二介面部5係將進行過批次處理的基板W搬運至單片處理部6。搬運至單片處理部6的基板W,係在單片處理部6中進行單片處理。如此,分配至批次處理部4的基板W,會在進行完包含批次處理與單片處理的複合處理後,回到位於裝載器23的基板匣盒C。
在對從第一基板匣盒取出之基板W進行複合處理的途中,若單片處理之對象亦即第二基板匣盒被搬運至裝載器23時,則第一介面部3會將第二基板匣盒所收納的基板W分配至單片處理部6。分配至單片處理部6的基板W係在單片處理部6中進行單片處理。
如此,依實施態樣之基板處理方法,可並行實施包含批次處理與單片處理的複合處理,及未經由批次處理部4的單片處理。
複合處理之對象亦即第一基板匣盒,例如係收納製品基板的基板匣盒。單片處理之對象亦即第二基板匣盒,例如係收納擋片基板的基板匣盒。此情況下,可並行實施對製品基板的複合處理,及使用擋片基板的單片處理部6中之擋片處理。作為擋片處理,例如可舉在對配置成多段之乾燥裝置63的至少一個乾燥裝置63進行零件更換等後,於該乾燥裝置63中運行多數擋片基板而提高該乾燥裝置63之潔淨度的處理。擋片基板與製品基板不同,不需要進行批次處理(例如化學藥液處理)。透過在不經由批次處理部4的情況下將擋片基板搬運至單片處理部6,可省略多餘的搬運,而可縮短擋片處理所需要的時間。又,第一基板匣盒亦可收納施予複合處理的第一製品基板,第二基板匣盒亦可收納僅施予單片處理的第二製品基板。
又,單片處理之對象亦即第二基板匣盒亦可為收納製品基板的基板匣盒。此情況下,可並行實施對製品基板的複合處理,及對製品基板的單片處理。又,複合處理之對象亦即第一基板匣盒亦可係收納擋片基板的基板匣盒。如此,第一基板匣盒及第二基板匣盒所收納的基板之種類並不限定。又,即使對於三個以上的基板匣盒C,亦可同樣地並行實施複合處理及單片處理。
吾人應瞭解到,本次所揭露的實施態樣所有內容均為示例而非限制。上述的實施態樣在不脫離附加之申請專利範圍及其主旨的情況下,亦能以各式各樣的形態進行省略、替換、變更。
