Description
本發明係關於一種研削加工被保持在保持台上之晶圓的加工裝置。The present invention relates to a processing apparatus for grinding and processing a wafer held on a holding table.
研削晶圓的研削裝置至少具備有保持晶圓的保持台，使保持台旋轉的馬達，用於安裝馬達的馬達托架，以及環狀地配設有研削磨石的研削輪，其中研削磨石研削保持在保持台上的晶圓，一邊藉由馬達使保持台旋轉，一邊以研削磨石研削保持台所保持的晶圓（例如，參閱下列的專利文件1）。A grinding device for grinding a wafer includes at least a holding table for holding a wafer, a motor for rotating the holding table, a motor bracket for mounting the motor, and a grinding wheel in which grinding wheels are arranged annularly. The wafer held on the holding table is ground, and the wafer held on the holding table is ground with a grinding stone while the holding table is rotated by a motor (for example, see Patent Document 1 below).
使保持台旋轉的馬達，由於在旋轉動作時會發熱，所以馬達的熱度被傳導至保持台使得保持台的傾斜度變化，或使得保持面的形狀變化，而有晶圓的面內無法研削為均一厚度的問題。因此，有具備在馬達托架的內部設置水路使水流通，以斷開馬達的熱度之冷卻機構者。 [習知技術文獻] [專利文獻]The motor that rotates the holding table generates heat during the rotation operation, so the heat of the motor is transmitted to the holding table so that the inclination of the holding table changes, or the shape of the holding surface changes, and the in-plane with wafer cannot be ground to The problem of uniform thickness. Therefore, there is a cooling mechanism provided with a water path inside the motor bracket to allow water to circulate to shut off the heat of the motor. [Habitual technical literature] [patent literature]
[專利文獻1]日本特開2010-89234號公報[Patent Document 1] Japanese Patent Laid-Open No. 2010-89234
[發明所欲解決的課題] 然而，根據流通在水路中的水之水質會有水路被阻塞的情況，在此情況下，有交換馬達托架的必要。例如，在藉由皮帶傳動機構使保持台旋轉時，因為在交換馬達托架時有暫時鬆開皮帶以調整皮帶張力的必要，所以會花費作業時間。此外，在上述專利文件1所示的研削裝置中，因為是以不具有水路的馬達托架安裝馬達，會有在稍後需要冷卻機構的情況。在此情況下，也有在交換馬達托架時需要調整皮帶張力，而花費作業時間的問題。[Problems to be Solved by the Invention] However, depending on the quality of the water flowing through the water channel, the water channel may be blocked. In this case, it is necessary to exchange the motor bracket. For example, when the holding table is rotated by a belt transmission mechanism, it is necessary to loosen the belt temporarily to adjust the belt tension when the motor bracket is exchanged, so it takes time to work. Moreover, in the grinding apparatus shown in the said patent document 1, since a motor is mounted with the motor bracket which does not have a water path, a cooling mechanism may be needed later. In this case, there is also a problem that it is necessary to adjust the belt tension when the motor bracket is exchanged, and it takes time to work.
本發明係因為有鑑於上述情況，目的是在於不進行傳動機構的調整下要能夠交換及追加冷卻機構，並且要能夠縮短作業時間，其中傳動機構將馬達的旋轉力傳動至保持台。In view of the above circumstances, the present invention aims to be able to exchange and add a cooling mechanism without adjusting the transmission mechanism, and to shorten the working time. The transmission mechanism transmits the rotational force of the motor to the holding table.
[解決課題的技術手段] 本發明是一種加工裝置，其具備保持晶圓的保持手段，以及加工該晶圓的加工手段；其中，該保持手段具備：保持台，其保持晶圓；旋轉軸，其使該保持台的中心繞軸旋轉；保持基座，其旋轉自如地支撐該旋轉軸，並被裝置基台所支撐；馬達，其為該旋轉軸的旋轉動力源，透過板狀的馬達托架配設於該保持基座或裝置基台；傳動手段，其將該馬達的旋轉力傳動至該旋轉軸；以及冷卻套，其冷卻該馬達托架；該冷卻套具備：冷卻水路，其接觸該馬達托架且在內部使冷卻水流通。[Technical means for solving the problem] The present invention is a processing device including a holding means for holding a wafer and a processing means for processing the wafer; wherein the holding means includes a holding table that holds the wafer, and a rotating shaft, It rotates the center of the holding table about an axis; a holding base that supports the rotating shaft freely and is supported by the device base; a motor, which is a rotational power source of the rotating shaft, passes through a plate-shaped motor bracket Disposed on the holding base or device base; a transmission means that transmits the rotational force of the motor to the rotation shaft; and a cooling jacket that cools the motor bracket; the cooling jacket is provided with: a cooling water path that contacts the The motor bracket circulates cooling water inside.
[發明功效] 本發明的加工裝置具備保持晶圓的保持手段，保持手段具備：保持晶圓的保持台，使保持台的中心繞軸旋轉的旋轉軸，旋轉自如地支撐旋轉軸並被裝置基台所支撐的保持基座，透過板狀的馬達托架配設於保持基座或裝置基台且為旋轉軸之旋轉動力源的馬達，將馬達的旋轉力傳動至旋轉軸的傳動手段，以及冷卻馬達托架的冷卻套；因為冷卻套具備接觸馬達托架且在內部使冷卻水流通的冷卻水路，所以不用將馬達與馬達托架一起從保持基座或裝置基台卸除，而能容易地對馬達托架進行冷卻套的裝卸。從而，在傳動手段為由例如皮帶傳動機構所組成的情況下，不進行皮帶張力的調整，而能夠交換及追加冷卻套，可以縮短作業時間。此外，即使在傳動手段為由例如齒輪傳動機構所組成的情況下，也不需調整齒輪的咬合，與上述相同，可以縮短作業時間。[Effects of the Invention] The processing device of the present invention includes a holding means for holding the wafer. The holding means includes a holding table holding the wafer, a rotating shaft that rotates the center of the holding table about the axis, and supports the rotating shaft rotatably and is supported by the device base. The holding base supported by the table is a motor that is arranged on the holding base or the device base and is a rotating power source of the rotating shaft through a plate-shaped motor bracket, a transmission means for transmitting the rotating force of the motor to the rotating shaft, and cooling The cooling jacket of the motor bracket; since the cooling jacket has a cooling water path that contacts the motor bracket and circulates cooling water inside, the motor and the motor bracket can be easily removed without removing the motor from the holding base or the device base. Attach and remove the cooling jacket to the motor bracket. Therefore, when the transmission means is composed of, for example, a belt transmission mechanism, it is possible to exchange and add a cooling jacket without adjusting the belt tension, and to shorten the working time. In addition, even in a case where the transmission means is composed of, for example, a gear transmission mechanism, it is not necessary to adjust the meshing of the gears, and the operation time can be shortened as described above.

馬達24的前端上連接有軸240。本實施方式所示的裝置基台10之內部中，形成有具有固定面101的安裝洞100，其中馬達托架26固定於固定面101。在固定面101上，形成有使軸240貫穿的貫穿孔102，在軸貫穿孔102的周圍有使第1螺絲6螺合的第1內螺紋103，以及使第2螺絲7螺合的第2內螺紋104。A shaft 240 is connected to the front end of the motor 24. A mounting hole 100 having a fixing surface 101 is formed inside the device base 10 shown in this embodiment, and the motor bracket 26 is fixed to the fixing surface 101. The fixing surface 101 is formed with a through-hole 102 through which the shaft 240 is penetrated, and around the shaft through-hole 102 are a first internal screw thread 103 for screwing the first screw 6 and a second screw thread for screwing the second screw 7内 Thread 104.
如圖3所示，傳動手段25是由連接至旋轉軸21的從動皮帶輪250，透過馬達托架26連接至馬達24的驅動皮帶輪251，以及纏繞在從動皮帶輪250和驅動皮帶輪251上的皮帶252所構成。馬達24的軸240的上端連接有驅動皮帶輪251。當馬達24使驅動皮帶輪251驅動時，皮帶252使從動皮帶輪250跟隨動作以將旋轉力傳動至旋轉軸21，並且能夠使保持台20和旋轉軸21一起旋轉。作為將旋轉力傳動至旋轉軸21的傳動手段25，並不限定為本實施方式所示的皮帶傳動機構的構成，也可以藉由齒輪傳動機構來構成傳動手段25。As shown in FIG. 3, the transmission means 25 is a driven pulley 250 connected to the rotation shaft 21, a driving pulley 251 connected to the motor 24 through a motor bracket 26, and a belt wound around the driven pulley 250 and the driving pulley 251. 252. A drive pulley 251 is connected to an upper end of a shaft 240 of the motor 24. When the motor 24 drives the driving pulley 251, the belt 252 causes the driven pulley 250 to follow the action to transmit the rotational force to the rotation shaft 21, and can rotate the holding table 20 and the rotation shaft 21 together. The transmission means 25 that transmits the rotational force to the rotating shaft 21 is not limited to the configuration of the belt transmission mechanism shown in this embodiment, and the transmission means 25 may be configured by a gear transmission mechanism.
馬達托架26是形成為例如矩形板狀，具備使馬達24的軸240貫穿的貫穿孔260，以及形成在貫穿孔260周圍的多個（例如2個）的第1插入孔261和多個（例如2個）的第2插入孔262。第1插入孔261是對應於圖2所示第1內螺紋103的位置。此外，第2插入孔262是對應第2內螺紋104的位置。The motor bracket 26 is formed in a rectangular plate shape, for example, and includes a through hole 260 through which the shaft 240 of the motor 24 passes, and a plurality of (for example, two) first insertion holes 261 and a plurality of (for example, two) formed around the through hole 260. For example, two) second insertion holes 262. The first insertion hole 261 is a position corresponding to the first internal thread 103 shown in FIG. 2. The second insertion hole 262 is a position corresponding to the second female screw 104.
在此，當透過馬達托架26將馬達24安裝在裝置基台10之內部時，使軸240貫穿馬達托架26的貫穿孔260和軸貫穿孔102以從裝置基台10的上表面突出，並且使馬達托架26抵接固定面101。在此狀態下，藉由將第1螺絲6從第1插入孔261插入且螺合至第1內螺紋103，將馬達托架26固定在固定面101上。當將馬達24從固定面101卸除時，進行上述安裝動作的逆向動作即可。Here, when the motor 24 is mounted inside the device base 10 through the motor bracket 26, the shaft 240 is passed through the through hole 260 and the shaft through hole 102 of the motor bracket 26 to protrude from the upper surface of the device base 10. Then, the motor bracket 26 is brought into contact with the fixing surface 101. In this state, the motor bracket 26 is fixed to the fixing surface 101 by inserting and screwing the first screw 6 from the first insertion hole 261 to the first internal thread 103. When the motor 24 is detached from the fixing surface 101, the reverse operation of the mounting operation described above may be performed.
冷卻套27是形成為例如U字形，在其內側具有開口270。冷卻套27的端部27a、27b上分別形成有使第2螺絲7插入的插入孔271。插入孔271的位置是對應於馬達托架26的第2插入孔262的位置。本實施方式所示冷卻套27，因為由U字形所組成，能夠防止馬達24接觸冷卻套27的側面。另外，冷卻套27只要是能夠圍繞馬達24的形狀即可，並不特別限定為U字形，也可以是例如ㄈ字形。The cooling jacket 27 is formed in a U-shape, for example, and has an opening 270 on the inside thereof. Insertion holes 271 through which the second screws 7 are inserted are formed in the end portions 27a and 27b of the cooling jacket 27, respectively. The position of the insertion hole 271 corresponds to the position of the second insertion hole 262 of the motor bracket 26. Since the cooling jacket 27 shown in this embodiment is formed of a U-shape, it is possible to prevent the motor 24 from contacting the side surface of the cooling jacket 27. The cooling jacket 27 is not limited to a U-shape as long as it has a shape capable of surrounding the motor 24, and may be, for example, a U-shape.
如圖4所示，在冷卻套27的內部形成有使冷卻水8流通的冷卻水路272。在冷卻套27的端部27a側的冷卻水路272連接有供給管28，其中供給管28從冷卻水循環裝置5將經調節至預定溫度的冷卻水8供給至冷卻水路272。此外，在冷卻套27的端部27b側的冷卻水路272，連接有從冷卻水路272將冷卻水8排出的排水管29。當從冷卻水循環裝置5通過供給管28使冷卻水8流入冷卻水路272內時，冷卻水8沿著冷卻水路272流去，從排水管29排出。當被排出的冷卻水8流入冷卻水循環裝置5時，再次被調節到預定溫度後被送往供給管28。這種冷卻套27是以冷卻水8不斷地在冷卻水路272內循環的方式所構成。As shown in FIG. 4, a cooling water passage 272 through which the cooling water 8 flows is formed inside the cooling jacket 27. A supply pipe 28 is connected to the cooling water passage 272 on the end 27 a side of the cooling jacket 27, and the supply pipe 28 supplies the cooling water 8 adjusted to a predetermined temperature from the cooling water circulation device 5 to the cooling water passage 272. Further, a drain pipe 29 that discharges the cooling water 8 from the cooling water passage 272 is connected to the cooling water passage 272 on the end portion 27 b side of the cooling jacket 27. When the cooling water 8 flows into the cooling water path 272 from the cooling water circulation device 5 through the supply pipe 28, the cooling water 8 flows along the cooling water path 272 and is discharged from the drain pipe 29. When the discharged cooling water 8 flows into the cooling water circulation device 5, it is adjusted to a predetermined temperature again and sent to the supply pipe 28. The cooling jacket 27 is configured such that the cooling water 8 is continuously circulated in the cooling water passage 272.
當冷卻套27安裝至馬達托架26時，如圖5所示，使冷卻套27的插入孔271與馬達托架26的第2插入孔262一致，並使冷卻套27接觸馬達托架26的下表面。隨後，將第2螺絲7插入至插入孔271和第2插入孔262，並藉由螺合以緊固至圖2所示裝置基台10的第2內螺紋104，以將冷卻套27固定在馬達托架26上。藉此，將馬達24定位在開口270，並使馬達24的側面成為以冷卻套27圍繞的狀態。當將冷卻套27從馬達托架26卸除時，僅藉由將第2螺絲7從插入孔271和第2插入孔262卸除，就能夠容易地將冷卻套27從馬達托架26卸除。此外，在冷卻套27，藉由U字形的內側面接觸圓柱狀馬達24的外側面，能夠將馬達托架26冷卻並且將馬達24冷卻。When the cooling jacket 27 is attached to the motor bracket 26, as shown in FIG. 5, the insertion hole 271 of the cooling jacket 27 is aligned with the second insertion hole 262 of the motor bracket 26, and the cooling jacket 27 contacts the motor bracket 26. lower surface. Subsequently, the second screw 7 is inserted into the insertion hole 271 and the second insertion hole 262, and is screwed to the second internal thread 104 of the device base 10 shown in FIG. 2 to fix the cooling jacket 27 on the Motor bracket 26. Thereby, the motor 24 is positioned in the opening 270, and the side surface of the motor 24 is in a state surrounded by the cooling jacket 27. When the cooling jacket 27 is removed from the motor bracket 26, the cooling jacket 27 can be easily removed from the motor bracket 26 only by removing the second screw 7 from the insertion hole 271 and the second insertion hole 262. . In addition, in the cooling jacket 27, the U-shaped inner surface contacts the outer surface of the cylindrical motor 24, so that the motor bracket 26 can be cooled and the motor 24 can be cooled.
接著，說明關於圖1所示加工裝置1的操作例。晶圓W為圓形板狀的工件之一例示，並不特別限定材質等。當研削加工晶圓W時，以受到未圖示之吸引源的作用之保持面20a吸引保持晶圓W，並使保持台20移動至加工手段3的下方。隨後，驅動馬達24以藉由傳動手段25將旋轉力傳動至旋轉軸21，並使保持台20在預定方向上旋轉。加工手段3藉由使主轉30旋轉，一邊使研削輪35在預定方向上旋轉，一邊藉由昇降手段4使加工手段3在接近保持台20之保持面20a的方向下降，且以邊旋轉邊下降的研削磨石36一邊推壓晶圓W一邊研削加工達到預定的厚度為止。Next, an operation example of the processing device 1 shown in FIG. 1 will be described. The wafer W is an example of a circular plate-like workpiece, and the material and the like are not particularly limited. When grinding and processing the wafer W, the holding wafer 20 is attracted by the holding surface 20 a which is subjected to an attraction source (not shown), and the holding table 20 is moved below the processing means 3. Subsequently, the driving motor 24 transmits a rotational force to the rotation shaft 21 by the transmission means 25 and rotates the holding table 20 in a predetermined direction. The processing means 3 rotates the main rotation 30, while rotating the grinding wheel 35 in a predetermined direction, and the lifting means 4 lowers the processing means 3 in a direction close to the holding surface 20a of the holding table 20, and rotates while rotating The falling grinding stone 36 is pressed until the wafer W is pressed to a predetermined thickness.
在晶圓W的研削中，因為持續使保持台20旋轉，馬達24會發熱。因此，如圖4所示， 藉由冷卻水循環裝置5不斷地使冷卻水8在冷卻套27的冷卻水路272上流通，以冷卻馬達24。也就是說，藉由在冷卻水路272內循環的冷卻水8的冷卻作用不斷地冷卻馬達24的周圍，移除馬達24的熱度，並且使得熱影響不會波及保持台20。另外，使用例如純水作為冷卻水8。During the grinding of the wafer W, since the holding table 20 is continuously rotated, the motor 24 generates heat. Therefore, as shown in FIG. 4, the cooling water circulation device 5 continuously circulates the cooling water 8 on the cooling water path 272 of the cooling jacket 27 to cool the motor 24. That is, the periphery of the motor 24 is continuously cooled by the cooling effect of the cooling water 8 circulating in the cooling water path 272, and the heat of the motor 24 is removed, so that the thermal influence does not affect the holding table 20. As the cooling water 8, for example, pure water is used.
如此一來，本發明的加工裝置1具備保持晶圓W的保持手段2，以及加工晶圓W的加工手段3，保持手段2具備：保持晶圓W的保持台20，使保持台20的中心繞軸旋轉的旋轉軸21，旋轉自如地支撐旋轉軸21並被裝置基台10所支撐的保持基座22，透過板狀的馬達托架26配設於保持基座22或裝置基台10且為旋轉軸21之旋轉動力源的馬達24，將馬達24的旋轉力傳動至旋轉軸21的傳動手段25，以及冷卻馬達托架26的冷卻套27；因為冷卻套27具備接觸馬達托架26且在內部使冷卻水8流通的冷卻水路272，所以不用將馬達24和馬達托架26一起從例如裝置基台10卸除，而能夠容易地對馬達托架26進行冷卻套27的裝卸。藉此，不進行皮帶252之皮帶張力的調整，而能夠交換及追加冷卻套27，並能夠縮短作業時間。此外，即使在傳動手段25為由齒輪傳動機構所組成的情況下，也不需調整齒輪的咬合，並能夠縮短作業時間。As described above, the processing device 1 of the present invention includes a holding means 2 for holding the wafer W and a processing means 3 for processing the wafer W. The holding means 2 includes a holding table 20 holding the wafer W and a center of the holding table 20. The rotating shaft 21 that rotates around the shaft supports the holding base 22 rotatably supporting the rotating shaft 21 and is supported by the device base 10. The plate-shaped motor bracket 26 is disposed on the holding base 22 or the device base 10 and The motor 24 is a rotation power source of the rotation shaft 21, a transmission means 25 for transmitting the rotation force of the motor 24 to the rotation shaft 21, and a cooling jacket 27 for cooling the motor bracket 26; The cooling water path 272 that circulates the cooling water 8 inside, so that the motor bracket 26 can be easily attached and detached to the motor bracket 26 without removing the motor 24 and the motor bracket 26 from, for example, the device base 10. Thereby, without adjusting the belt tension of the belt 252, the cooling jacket 27 can be replaced and added, and the work time can be shortened. In addition, even in a case where the transmission means 25 is composed of a gear transmission mechanism, it is not necessary to adjust the meshing of the gears, and the working time can be shortened.
上述實施方式所示的加工裝置1，雖作為研削裝置來說明，但並不限定於此構成，也可以是具備作為保持台20之旋轉驅動源的馬達24，且有使發熱的馬達24以冷卻套27冷卻必要的加工裝置。從而，本發明也能夠適用於例如研磨裝置等。Although the processing device 1 described in the above embodiment is described as a grinding device, it is not limited to this configuration, and it may be provided with a motor 24 as a rotation drive source of the holding table 20 and a motor 24 for generating heat for cooling The sleeve 27 cools the necessary processing equipment. Therefore, the present invention can also be applied to, for example, a polishing apparatus.
