Description
本發明係關於具備保持晶圓之複數吸盤台的研磨裝置。
於轉盤上具有保持晶圓之2以上的吸盤台之類型的研磨裝置,係藉由使轉盤旋轉,使其分別位於使各吸盤台公轉而加工晶圓的加工區域,與搬出入晶圓的搬出入區域,研磨位於加工區域的晶圓。晶圓的研磨中,係在加工區域中使用的研磨用水及研磨屑會散射,故在位於加工區域的吸盤台與位於搬出入區域的吸盤台之間設置區隔板,遮斷加工區域與搬出入區域(例如,參照後述之專利文獻1及2)。
前述之吸盤台係可在轉盤上旋轉,例如作為將使吸盤台旋轉的電動機直接連結於吸盤台的下部的構造。又,圖5所示先前的研磨裝置40為兩個吸盤台42配設成可在轉盤41上旋轉,於各吸盤台42的下方側配設電動機43的構造。於各電動機43,分別安裝驅動滑輪44,並且於連結於各吸盤台42之下部的旋轉軸420分別安裝
從動滑輪45,於驅動滑輪44與從動滑輪45分別捲繞於皮帶46。如此,即使任一構造之狀況中,都於轉盤的下側配置電動機,故容易進行電動機的交換作業。
[專利文獻1]日本特開2013-255952號公報
[專利文獻2]日本特開2013-086244號公報
但是,於轉盤的下側配置電動機的構造中,電動機的發熱所致之熱傳達至轉盤,故轉盤會熱變形,發生被研磨之晶圓不會成為所定厚度的加工不良。
本發明係有鑑於前述的情況所發明者,目的為防止電動機的發熱所致之熱波及轉盤,讓轉盤不會熱變形。
本發明是一種研磨裝置,係具備:2以上的保持手段,係具有使保持晶圓之吸盤台旋轉的電動機;轉盤,係2以上的該保持手段被均等間隔地配設且旋轉;區隔部,係配設於該轉盤上,並將2以上的吸盤台之間予以區隔;研磨手段,係具有研磨被該吸盤台保持之晶圓的研
磨砥石;及研磨用水供給手段,係對晶圓與該研磨砥石供給研磨用水;其特徵為:該電動機,係配設於該轉盤上;該區隔部,係具有將配設於該轉盤上的該電動機,收容於內側的凹部;藉由使該研磨用水接觸該區隔部的外側,冷卻該區隔部與被該區隔部收容的該電動機。
本發明相關的研磨裝置係具備具有使吸盤台旋轉的電動機之2以上的保持手段、2以上的保持手段被均等間隔地配設且旋轉的轉盤、配設於轉盤上,並將2以上的吸盤台之間予以區隔的區隔部、具有研磨晶圓的研磨砥石的研磨手段、及對晶圓與該研磨砥石供給研磨用水的研磨用水供給手段,電動機係配設於轉盤上,故易發熱之電動機的上部從轉盤露出,電動機的發熱所致之熱不會傳達至轉盤。
又,區隔部係具有將配設於轉盤上之電動機收容於內側的凹部,故於該凹部收容電動機之狀態下,藉由使研磨用水接觸區隔部的外側,冷卻區隔部與電動機,可讓熱影響不會波及轉盤。
藉此,在晶圓的研磨中防止轉盤熱變形,晶圓不會發生加工不良。

圖1所示之研磨裝置1,係具備保持被加工物即晶圓W之複數吸盤台的研磨裝置之一例,具有裝置基座2。於裝置基座2的Y軸方向前部側的上面2a,具備具有保持晶圓W之吸盤台50a、50b與使該等旋轉之電動機54的2以上的保持手段5a、5b、保持手段5a、5b被均等間隔地配設且旋轉的轉盤3、及配設於轉盤3上,將2以上的吸盤台50a、50b之間予以區隔的區隔部6。
於裝置基座2之Y軸方向後部側的上面2b,豎立設置有向Z軸方向延伸的支柱9。於支柱9的側方,隔著研磨進給手段30,配設具有研磨被吸盤台50a、50b保持的晶圓W之研磨砥石16的研磨手段10。
研磨手段10係藉由具有Z軸方向之軸心的主軸11、支持且可繞主軸11旋轉的主軸殼體12、連接於主軸11的一端的電動機13、連接於主軸11的下端的固定
機(mounter)14、可旋轉地安裝於固定機14的研磨輪15、及環狀固接於研磨輪15之下部的研磨砥石16所構成。藉由電動機13使主軸11以所定旋轉速度旋轉,可讓研磨輪15以所定旋轉速度旋轉。
於研磨手段10,連接有具有研磨用水供給源21的研磨用水供給手段20。研磨用水供給手段20係在晶圓W的研磨時,可從研磨用水供給源21對研磨砥石16與晶圓W的接觸部分供給研磨用水。再者,作為研磨用水,例如使用純水。
研磨進給手段30係藉由向Z軸方向延伸的滾珠螺絲31、連接於滾珠螺絲31的一端的電動機32、與滾珠螺絲31平行延伸之一對導引軌道33、及內部所具備之螺帽螺合於滾珠螺絲31,並且側部滑接於導引軌道33,研磨手段10固定於一方之面的升降部34所構成。研磨進給手段30係被電動機32驅動而滾珠螺絲31旋動,藉由沿著一對導引軌道33使升降部34向Z軸方向移動,可與升降部34一起使研磨手段10向Z軸方向升降。
於轉盤3的上面,安裝有覆蓋轉盤3的轉盤護蓋4。隔著該轉盤護蓋4,保持手段5a、5b與區隔部6配設於轉盤3上。轉盤3以圖2所示之旋轉軸3a為中心旋轉的話,則可使保持手段5a、5b公轉,在對晶圓W研磨加工的加工區域P1與搬出入晶圓W的搬出入區域P2之間使保持手段5a、5b依序移動。再者,保持手段5b係與保持手段5a相同構造,故以下針對保持手段5a的構造
詳細說明。
如圖1所示,構成保持手段5a的吸盤台50a的上面,成為保持晶圓W的保持面51。保持面51係例如藉由多孔陶瓷等的多孔質構件所形成。於吸盤台50a的下端,如圖2所示,連結有具有垂直方向之軸心的旋轉軸52。於旋轉軸52,連接旋轉接頭53,於旋轉接頭53,連接有連通於吸盤台50a之保持面51的吸引源7,與連通於轉盤3之下面的空氣供給源8。然後,藉由吸引源7使吸引力作用於吸盤台50a的保持面51時,可利用保持面51吸引保持晶圓W,藉由從空氣供給源8向轉盤3的下面噴吹空氣,可使轉盤3浮起。
於旋轉軸52,連接有在轉盤3上使吸盤台50a旋轉的旋轉機構。旋轉機構係如圖2所示,藉由配設於轉盤3上的電動機54、安裝於電動機54的驅動滑輪55、安裝於旋轉軸52的從動滑輪56、及捲繞於驅動滑輪55與從動滑輪56的皮帶57所構成。再者,在圖2的範例中雖未圖示,但是,於吸盤台50b側也連接有與吸盤台50a相同的旋轉機構。
電動機54係以從轉盤3上突出之方式配設。亦即,成為藉由使電動機54的驅動時易發熱的上部540從轉盤3露出,電動機54的熱不會傳達至轉盤3的配置構造。然後,藉由電動機54驅動驅動滑輪55時,皮帶57使從動滑輪56從動,可與旋轉軸52一起使吸盤台50a旋轉。
區隔部6係如圖1所示,延伸於X軸方向,配置於吸盤台50a與吸盤台50b之間。藉由利用區隔部6將吸盤台50a、50b之間予以區隔,於研磨時遮斷加工區域P1與搬出入區域P2。如此,藉由區隔部6,可防止加工區域P1中使用的研磨用水等散射至位於搬出入區域P2的吸盤台50a或吸盤台50b。
區隔部6係如圖2所示,至少在兩處(圖2中僅圖示1處)具有用以將配設於轉盤3上的各電動機54收容於內側的凹部60。於該凹部60,收容有保持手段5a、5b的各電動機54。因此,藉由研磨時從研磨用水供給源21供給至研磨砥石16與晶圓W的研磨用水接觸區隔部6的外側面61,可冷卻區隔部6與被區隔部6的凹部60收容的電動機54。再者,區隔部6之上端面62的高度位置,係位於至少比吸盤台50a、50b的保持面51還高的位置即可。
接著,針對研磨裝置1的動作例進行說明。圖1所示之晶圓W,係被加工物的一例,並不是限定其材質及厚度等者。首先,將晶圓W搬送至例如在搬出入區域P2待機的吸盤台50a。
利用吸盤台50a的保持面51吸引保持晶圓W之後,藉由使轉盤3旋轉,使吸盤台50a往加工區域P1移動。具體來說,將從空氣供給源8送來的空氣向轉盤3的下面噴吹而使其浮起之狀態下,使轉盤3向例如箭頭A方向旋轉。然後,伴隨轉盤3的旋轉,使吸盤台50a往研
磨手段10的下方移動。
接下來,如圖3所示,藉由電動機54的驅動,使吸盤台50a往例如箭頭A方向旋轉,並且研磨手段10一邊藉由使主軸11旋轉,使研磨輪15往例如箭頭A方向旋轉,一邊藉由圖1所示之研磨進給手段30,使研磨手段10往接近吸盤台50a的保持面51的方向下降,利用一邊旋轉一邊下降的研磨砥石16,對晶圓W一邊按壓一邊研磨至成為所定厚度為止。
此時,如圖3所示,從研磨用水供給源21對晶圓W與研磨砥石16的接觸部分供給研磨用水22,冷卻研磨砥石16並且洗掉研磨屑。研磨用水22係散射至旋轉之研磨砥石16的周圍,但是,接觸區隔部6的外側面61而被遮斷,故研磨用水22不會散射至吸盤台50b。
在此,研磨用水22散射的方向係如圖4所示,伴隨吸盤台50a及研磨砥石16的旋轉,朝向被區隔部6的內部收容的電動機54側。亦即,研磨用水22係從實際上研磨砥石16接觸研磨晶圓W的接觸部分100朝向箭頭B方向散射。因此,可有效率地使研磨用水22接觸對應收容電動機54的位置之區隔部6的外側面61,可冷卻區隔部6與被區隔部6收容的電動機54。
晶圓W的研磨中,係從圖3所示之研磨用水供給源21經常將研磨用水22持續供給至晶圓W與研磨砥石16,使研磨用水22持續接觸區隔部6的外側面61。如此一來,藉由研磨用水22的冷卻作用,利用時常冷卻
電動機54的上部540,去除電動機54的熱,讓熱影響不會波及轉盤3。
將晶圓W研磨成所定厚度之後,圖4所示之轉盤3更加旋轉,使吸盤台50a移動至搬出入區域P2,並且使保持未加工之晶圓W的吸盤台50b移動至加工區域P1,重覆進行與前述相同的研磨動作。
如此,本發明相關的研磨裝置1係具備具有使吸盤台50a、50b旋轉之電動機54的2以上的保持手段5a、5b、保持手段5a、5b被均等間隔地配設且旋轉的轉盤3、及配設於轉盤3上,將吸盤台50a、50b之間予以區隔的區隔部6,且使電動機54突出配設於轉盤3上,故電動機54的熱不會傳達至轉盤3。。又,區隔部6係具有將電動機54收容於內側的凹部60,故在將電動機54收容於區隔部6的凹部60之狀態下,藉由使研磨用水22接觸區隔部6的外側面61,可冷卻區隔部6與電動機54,熱影響不會波及轉盤3。如此,研磨時轉盤3不會熱變形,可將晶圓W加工成所定研磨厚度。
研磨裝置1係常為使電動機54從轉盤3突出的配置構造,但是,可從轉盤3的下方側進行電動機54的交換,故與先前同樣地可容易進行電動機的交換作業。
在本實施形態中,將1個區隔部6配設於吸盤台50a、50b之間,但是並不限定於該構造,可因應配設於轉盤的吸盤台的數量,變更區隔部6的數量、形狀及配設位置。
又,在本實施形態1中,成為具備1個研磨手段10的構造,但是並不限定於該構造。例如,具備兩個研磨手段(粗研磨手段及完成研磨手段)亦可,具備研削手段亦可。
