IC、LSI等多個元件為交叉的多條分割預定線所劃分並形成於晶圓的正面上,該晶圓係藉由切割裝置而被分割成各個元件晶片,所分割的元件晶片被利用於行動電話、個人電腦等電子設備(參照例如專利文獻1)。Multiple components such as IC, LSI, etc. are divided by multiple predetermined dividing lines that intersect and are formed on the front surface of the wafer. The wafer is divided into individual component chips by a dicing device, and the divided component chips are used in Electronic devices such as mobile phones and personal computers (see, for example, Patent Document 1).
此外,晶圓係在被分割成各個元件晶片之前,被定位於具有收容晶圓的開口部之環狀框架的該開口部,和環狀框架一起黏貼黏著膠膜而一體構成。In addition, the wafer is positioned in the opening of a ring frame having an opening for accommodating the wafer before being divided into individual element wafers, and an adhesive film is bonded together with the ring frame to form an integrated structure.
然後,對晶圓實施切割加工,分割成各個元件晶片後,對與晶圓對應的黏著膠膜的區域照射紫外線而減低黏著力。其後,各個元件晶片從黏著膠膜被拾取(pickup)後,被接合(bonding)於配線基板上。 [習知技術文獻] [專利文獻]Then, the wafer is diced and divided into individual element wafers, and then ultraviolet rays are irradiated to the area of the adhesive film corresponding to the wafer to reduce the adhesive force. After that, each element chip is picked up from the adhesive film and then bonded on the wiring substrate. [Conventional Technical Literature] [Patent Literature]

使卡盤台10在X軸方向的裝卸區域A與加工區域B之間移動的移動手段係藉由以下構件而實現:台座部15,其透過支柱14而固定晶圓支撐台12;一對導軌17,其配設於基台1a上;滾珠螺桿18,其配設於導軌17間;以及馬達16,其旋轉驅動滾珠螺桿18。台座部15構成為可沿著上述的導軌17滑動,利用適當形成於台座部15底部下表面的未圖示的接合手段,使其和滾珠螺桿18接合。利用馬達16使滾珠螺桿18正轉或反轉,藉此可和台座部15一起使卡盤台10在X軸方向移動。在導軌17與台座部15之間配設有未圖示的位置檢測手段,該位置檢測手段以及馬達16連接於未圖示的控制手段,可將卡盤台10正確定位於所希望的位置上。The moving means for moving the chuck table 10 between the loading and unloading area A and the processing area B in the X-axis direction is realized by the following components: a
其次,就切割手段20進行說明。切割手段20具備固定於旋轉軸221前端部的切割刀片21,切割刀片21透過旋轉軸221而為主軸單元22所支撐。在主軸單元22的後端側配設有主軸馬達23,利用主軸馬達23,透過旋轉軸221可使切割刀片21以高速旋轉驅動。主軸單元22配設於滑動構件24的滑動板25上,滑動板25利用配設於滑動構件24上的Z軸方向移動馬達26,可沿著滑動構件24在以箭頭Z所示的Z軸方向精密地進退。Next, the cutting means 20 will be described. The cutting means 20 includes a
滑動構件24利用設於豎立在基台1a上的壁部1b的跟前側的側面的滑移手段,可使其在水平方向(Y軸方向)滑動自如地移動。此滑移手段係由以下構件所構成:一對導軌27,其以平行配設於壁部1b側面的水平方向;滾珠螺桿28,其水平配設於一對導軌27之間;以及Y軸方向移動馬達29,其將滾珠螺桿28在正轉或反轉方向旋轉驅動。而且,滑動構件24滑動自如地懸吊於一對導軌27上,並且在滑動構件24的背面側,和滾珠螺桿28為適當的接合手段所接合。利用如此構成的滑移手段,藉由使Y軸方向移動馬達29在正轉方向或反轉方向旋轉,使滑動構件24在Y軸方向精密地進退。The sliding
如圖2所示,配設於卡盤台10的蓋構件11中央的晶圓支撐台12具備:正面部120,其係由圓形狀的支撐基板122、以及圍繞支撐基板122的框部121所構成。再者,從圖3所示可理解,從正面部120卸下支撐基板122的狀態,在為框部121所圍繞的區域且為支撐基板122的背面側,配設有朝向上方照射紫外線的紫外線照射手段60。紫外線照射手段60具備配設於框部121底部的紫外線照射基板62,在紫外線照射基板62上的劃分成格子狀的多個區域,備置有紫外線照射源(紫外線LED)64。此外,如圖4所示,在不配設紫外線照射基板62的紫外線照射源64的區域,配設有上下(正面背面)貫穿的連通孔66。電源72透過從框部121的下表面連接的電源供給電路70而連接於各紫外線照射源64。As shown in FIG. 2, the wafer support table 12 disposed in the center of the
支撐基板122係由透明的具有透氣性的板狀構件,例如多孔玻璃(porous glass)所構成。如圖3以及圖4所示,支撐基板122載置於上述的框部121內的紫外線照射手段60上,且使支撐基板122的上表面和框部121的上表面一致。使吸引通路141產生負壓的吸引手段(圖示省略)連接於通過晶圓支撐台12內的吸引通路141,透過紫外線照射基板62的連通孔66與具有透氣性的支撐基板122,使負壓透過黏著膠膜T而作用於保持在支撐基板122上表面的晶圓W。再者,支撐基板122未必需要是全體具有透氣性的多孔玻璃,也可以是平坦的略圓形狀的純粹的玻璃板。這種情況,要在多處形成上下連通於支撐基板122的外周部與框部121的邊界的間隙,透過該間隙,使負壓作用於支撐基板122上即可。The
本實施方式的切割裝置1大致構成如上述,茲就使用上述的切割裝置1將晶圓W分割成各個元件晶片的步驟,說明於下。The dicing device 1 of this embodiment is roughly configured as described above, and the steps of dividing the wafer W into individual element wafers using the dicing device 1 described above are described below.
當使用切割裝置1切割晶圓W時,如圖5所示,準備晶圓W,晶圓W透過黏著膠膜T而為具有開口部的環狀框架F所支撐。晶圓W的多個元件4透過分割預定線6而被劃分並形成於正面Wa上。黏著膠膜T係藉由照射紫外線而使黏著力降低的膠膜,例如可使用塗布有由丙烯酸系基底樹脂等構成的UV硬化糊的膠膜,該UV硬化糊係藉由對由聚氯乙烯(PVC)構成的片狀基材的黏貼面(黏貼晶圓W的面)照射紫外線,加以硬化而使黏著力降低者。再者,藉由照射紫外線而使黏著力降低的膠膜為眾所周知,只要是藉由照射紫外線而使黏著力降低的膠膜,則使用上述的黏著膠膜T以外的膠膜也無妨。When the wafer W is diced using the dicing device 1, as shown in FIG. 5, the wafer W is prepared, and the wafer W is supported by the ring frame F having an opening through the adhesive film T. The
如上述,若已準備透過黏著膠膜T而為環狀框架F所支撐的晶圓W,就以黏著膠膜T側為下而載置並吸引保持在定位於裝卸區域A的卡盤台10的晶圓支撐台12的正面部120上,以框架支撐部13固定支撐晶圓W的環狀框架F。若已在卡盤台10上保持晶圓W,就將卡盤台10移動到加工區域B側。As described above, if the wafer W supported by the ring frame F through the adhesive film T is prepared, the chuck table 10 positioned in the loading and unloading area A is placed and held with the adhesive film T side as the bottom. On the
如圖6所示,切割手段20的主軸單元22具備:切割刀片21,其被固定於旋轉軸221的前端部,在外周具有切割刃;以及刀片蓋223,其保護切割刀片21。切割刀片21為例如電鑄磨石,設定成直徑為50mm、厚度為30μm。切割刀片21藉由主軸馬達23的驅動,而以例如20,000rpm的速度旋轉。關於刀片蓋223,在與切割刀片21鄰接的位置上配設有切割水供給手段224,朝向切割刀片21的切割位置供給切割水。當利用切割刀片21實施切割加工時,預先使用未圖示的對準(alignment)手段,進行切割刀片21與為卡盤台10所保持的晶圓W的加工位置的對位(對準)。關於該對準手段,至少具備未圖示的照明手段、以及攝像手段,構成為可從晶圓W的正面Wa側拍攝、檢測晶圓W的正面Wa的分割預定線6。As shown in FIG. 6, the
若已實施該對準手段的對準,就將和旋轉軸221一起高速旋轉的切割刀片21定位於晶圓W上的預定的加工開始位置,使切割刀片21的下端位置下降並切入到完全切割晶圓W、稍微到達黏著膠膜T的高度位置,使保持晶圓W的卡盤台10相對於切割刀片21在以箭頭X所示的X軸方向(加工進給方向)移動。此時的加工進給速度設定為例如50mm/秒。藉此,如圖6所示,切割與晶圓W的分割預定線6對應的區域,形成切割槽100。然後,一面利用上述的移動手段,使卡盤台10在X軸方向以及和X軸方向正交的方向適當移動,一面對晶圓W的預定方向的所有分割預定線6,利用上述的切割刀片21形成切割槽100。若是已對應卡盤台10的預定方向的所有分割預定線6而形成了切割槽100,就使晶圓支撐台12旋轉90度,在和上述的預定方向正交的方向,在與分割預定線6對應的區域,和上述同樣地形成切割槽100。藉此,在與晶圓W的所有分割預定線6對應的區域,形成切割槽100。其結果,如圖7所示,形成於晶圓W的正面Wa上的元件4被分割成各個元件晶片4,
。If the alignment by the alignment means has been performed, the
若已如上述般,實施了利用切割手段20形成切割槽100的切割加工,就如圖8所示,一面從清洗手段40朝向下方使清洗水42以高壓噴出,一面使卡盤台10從X軸方向,即加工區域B側朝向裝卸區域A移動。藉此,清洗晶圓W、黏著膠膜T、以及環狀框架F,去除切割加工時飛散的未圖示的切割屑。再者,當從清洗手段40噴出清洗水42時,為了使清洗效果提高,較佳是使清洗水42以高壓空氣噴射的雙流體噴射。If the cutting process of forming the cutting
若已如上述般,清洗了晶圓W、黏著膠膜T、以及環狀框架F,就使卡盤台10定位於裝卸區域A後停止。若已在裝卸區域A使卡盤台10停止,就如從圖9(作為晶圓支撐台12以及晶圓W的局部放大剖面圖所示)可理解般,使紫外線照射源64作動預定時間(例如30秒程度)。從紫外線照射源64照射之在圖中以UV所示的紫外線會穿透由多孔玻璃構成的支撐基板122,照射到與晶圓W對應的區域的黏著膠膜T,減低黏著膠膜T的黏著力。即,對黏著膠膜T照射紫外線,覆蓋於黏著膠膜T正面(黏貼有晶圓W的面)的UV硬化糊就會硬化,而使黏著力降低。再者,此時的黏著力降低,是指保持黏著膠膜T上的各個元件晶片4,
的程度被某種程度地降低,而不是達到完全喪失黏著力程度的降低。此外,該紫外線的照射,是上述的清洗手段40的清洗之後,即在清洗水42殘留於晶圓W、膠膜T上的狀態被實施。一般藉由照射紫外線而使黏著力降低的UV硬化糊,若是在含有氧氣的空氣內照射紫外線,黏著力的降低會較小。因此,如上述,在晶圓W、黏著膠膜T上留下清洗水42的狀態下,從黏著膠膜T的下表面側照射紫外線,藉此將黏著膠膜T與空氣中的氧氣隔離,可有效地使黏著力降低。If the wafer W, the adhesive film T, and the ring frame F have been cleaned as described above, the chuck table 10 is positioned in the loading and unloading area A and then stopped. If the chuck table 10 has been stopped in the loading and unloading area A, as can be understood from FIG. 9 (shown as a partial enlarged cross-sectional view of the wafer support table 12 and the wafer W), the
若已如上述般,從支撐晶圓W的黏著膠膜T的下表面側照射紫外線而使黏著膠膜T的黏著力降低了,就如圖10所示,以作業員的手(以H表示)夾持在裝卸區域A的為卡盤台10所保持的環狀框架F,從與裝卸區域A對應所設的開口部,和環狀框架F一起取出晶圓W。此時,從鼓風手段50的下表面噴射高壓空氣52,吹掉殘留於環狀框架F上的清洗水42,形成去除了水分的乾燥狀態。再者,圖10中雖然表示以作業員的手作業實施取出環狀框架F的作業的例子,但未必要受以手作業取出限定,也可以使用具備吸附手段的懸臂等的自動搬出裝置。如上述,從裝卸區域A搬出的晶圓W被搬送到下一個步驟(例如拾取步驟、接合(bonding)步驟等),或是被搬送到和環狀框架F一起收容晶圓W的未圖示的收容卡匣並收容。If, as described above, ultraviolet rays are irradiated from the lower surface of the adhesive film T supporting the wafer W to reduce the adhesive force of the adhesive film T, as shown in Figure 10, the operator’s hand (indicated by H ) The ring frame F held by the chuck table 10 clamped in the loading and unloading area A, and the wafer W is taken out together with the ring frame F from the opening provided in the loading and unloading area A. At this time, the high-
如上述,依據本實施方式的切割裝置1,使其具備:紫外線照射手段60,其係對構成卡盤台10的晶圓支撐台12照射紫外線,而減低與晶圓W對應的區域的黏著膠膜T的黏著力。藉此,無需配設和切割裝置1分離的紫外線照射裝置,可以實現裝置的省空間化,抑制設備費。尤其是,使晶圓支撐台12備置支撐基板122,支撐基板122支撐晶圓W並使紫外線穿透,並在支撐基板122的背面側備置紫外線照射源64,藉此更有效地實現裝置的省空間化。As described above, according to the dicing device 1 of the present embodiment, it is provided with the ultraviolet irradiation means 60, which irradiates the wafer support table 12 constituting the chuck table 10 with ultraviolet rays to reduce the adhesive in the area corresponding to the wafer W Adhesion of film T. Thereby, there is no need to arrange an ultraviolet irradiation device separate from the cutting device 1, and the space saving of the device can be realized and the equipment cost can be reduced. In particular, the wafer support table 12 is provided with a
