First, by slicing the cylindrical ingot with a wire saw, a sliced wafer is produced. This wafer is ground or etched to remove curl and warpage.

為了藉由研削而除去捲曲和翹曲，會在晶圓的其中一面的整面形成包含樹脂層的保護構件（例如專利文獻1）。保護構件形成後，透過保護構件藉由卡盤台保持晶圓，並藉由研削磨石研削晶圓的另一面。研削後，從晶圓的其中一面剝離保護構件，反轉晶圓，藉由卡盤台保持晶圓的另一面，並研削晶圓的其中一面。藉此，製造預定的厚度的晶圓。In order to remove curl and warpage by grinding, a protective member including a resin layer is formed on the entire surface of one surface of the wafer (for example, Patent Document 1). After the protective member is formed, the wafer is held by the chuck table through the protective member, and the other side of the wafer is ground by a grinding stone. After grinding, the protective member is peeled off from one side of the wafer, the wafer is reversed, the other side of the wafer is held by the chuck table, and one side of the wafer is ground. Thereby, a wafer with a predetermined thickness is manufactured.

The shelf 511 is installed in such a way that the transfer cassette 51 penetrates from the side of the protective member forming device 2 to the side of the grinding device 3, and is used to take out or put the wafer W into the shelf 511, and includes: the protective member forming device 2 The first opening 512 on the side and the second opening 513 on the side of the grinding device 3. The first transfer robot 21 of the protective member forming apparatus 2 shown in FIG. 1 passes through the first opening 512 to store the wafer W provided with the protective member in the shelf 511 of the delivery cassette 51.

研削裝置3研削晶圓W的正面Wa及背面Wb。研削裝置3具有第2搬送機械臂31。第2搬送機械臂31從圖3所示的交接卡匣51的層架511透過第2開口513取出具備保護構件的晶圓W，載置於研削裝置3的預定位置。研削裝置3具有殼體300，在其Y側的前表面設有容納兩面被研削的晶圓W之裝載埠LP。The grinding device 3 grinds the front Wa and the back Wb of the wafer W. The grinding device 3 has a second transport robot 31. The second transfer robot 31 takes out the wafer W provided with the protective member from the shelf 511 of the delivery cassette 51 shown in FIG. 3 through the second opening 513 and places it on a predetermined position of the grinding device 3. The grinding apparatus 3 has a housing 300, and a load port LP for accommodating wafers W to be ground on both sides is provided on the front surface of the Y side.

在本實施方式中，交接卡匣51、卡匣台座52、第1搬送機械臂21及第2搬送機械臂31是相當於將具備保護構件的晶圓W從保護構件形成裝置2搬送至研削裝置3之第1搬送機構的一例。In the present embodiment, the transfer cassette 51, the cassette base 52, the first transfer robot 21, and the second transfer robot 31 are equivalent to transferring the wafer W provided with the protective member from the protective member forming apparatus 2 to the grinding apparatus 3. An example of the first conveying mechanism.

剝離裝置4是藉由研削裝置3取得被研削的晶圓W，從晶圓W剝離保護構件。使剝離了保護構件的晶圓W回到研削裝置3。The peeling device 4 obtains the ground wafer W by the grinding device 3 and peels the protective member from the wafer W. The wafer W from which the protective member has been peeled is returned to the grinding apparatus 3.

以下說明晶圓製造裝置1的動作。 在晶圓製造裝置1中，首先，保護構件形成裝置2是在晶圓W的背面Wb的整面形成包含樹脂層的保護構件。The operation of the wafer manufacturing apparatus 1 will be described below. In the wafer manufacturing apparatus 1, first, the protective member forming apparatus 2 forms a protective member including a resin layer on the entire surface of the back surface Wb of the wafer W.

如圖4所示，在具有殼體200的保護構件形成裝置2中，首先，第1搬送機械臂21從容納切片晶圓的晶圓W之卡匣23a取出1片晶圓W，搬送至第1支撐台26a。晶圓檢測部27檢測晶圓W的中心位置及方向。之後，晶圓搬送部25從第1支撐台26a搬出晶圓W，交接至保持手段250。在保持手段250，保持台252吸附保持晶圓W的正面Wa。As shown in FIG. 4, in the protective member forming apparatus 2 having the casing 200, first, the first transfer robot 21 takes out one wafer W from the cassette 23a containing the wafer W of the sliced wafer, and transfers it to the first 1 Support 26a. The wafer detection unit 27 detects the center position and direction of the wafer W. After that, the wafer transport unit 25 unloads the wafer W from the first support table 26 a and transfers it to the holding means 250. In the holding means 250, the holding table 252 sucks and holds the front surface Wa of the wafer W.

薄片載置手段230的夾具部232將由使紫外線穿透的透明材料所組成的薄片F夾持，並與往晶圓W的保持手段250的搬送方向平行地在Y軸方向移動，藉此將薄片F從滾筒部211拉出。薄片F吸附保持於玻璃製的台座220的薄片保持面221。The clamp portion 232 of the sheet mounting means 230 clamps the sheet F composed of a transparent material that transmits ultraviolet rays, and moves in the Y-axis direction parallel to the conveying direction of the holding means 250 to the wafer W, thereby moving the sheet F F is pulled out from the roller part 211. The sheet F is sucked and held on the sheet holding surface 221 of the base 220 made of glass.

之後，樹脂供給手段240藉由使樹脂供給噴嘴241旋轉，將樹脂供給噴嘴241的供給口243定位於台座220的上方。接著，分配器242容納於樹脂槽（未圖示），吸取例如由紫外線硬化樹脂所組成的液狀樹脂（未圖示），並送出至樹脂供給噴嘴241。藉此，從樹脂供給噴嘴241朝向吸附保持於台座220的薄片F滴下預定量的液狀樹脂。After that, the resin supply means 240 rotates the resin supply nozzle 241 to position the supply port 243 of the resin supply nozzle 241 above the base 220. Next, the dispenser 242 is accommodated in a resin tank (not shown), sucks up a liquid resin (not shown) composed of, for example, ultraviolet curable resin, and sends it to the resin supply nozzle 241. Thereby, a predetermined amount of liquid resin is dropped from the resin supply nozzle 241 toward the sheet F sucked and held on the pedestal 220.

擴張手段260是藉由昇降板264將保持手段250的支撐構造251保持。擴張手段260藉由馬達262使滾珠螺桿261旋轉，藉此與昇降板264一同使保持手段250下降。伴隨保持手段250的下降，被吸附保持的晶圓W的背面Wb將吸附保持於台座220的薄片F上的液狀樹脂，以具有預定厚度之方式推開。The expansion means 260 holds the support structure 251 of the holding means 250 by the lifting plate 264. The expansion means 260 rotates the ball screw 261 by the motor 262, thereby lowering the holding means 250 together with the lifting plate 264. Along with the lowering of the holding means 250, the back surface Wb of the sucked and held wafer W pushes away the liquid resin sucked and held on the sheet F of the pedestal 220 so as to have a predetermined thickness.

之後，硬化手段270朝向藉由晶圓W的背面Wb被推開的液狀樹脂，透過台座220照射紫外光。其結果，液狀樹脂硬化，在晶圓W的背面Wb形成由液狀樹脂所組成的預定厚度的樹脂層。After that, the curing means 270 irradiates ultraviolet light through the pedestal 220 toward the liquid resin pushed away by the back surface Wb of the wafer W. As a result, the liquid resin is cured, and a resin layer composed of the liquid resin with a predetermined thickness is formed on the back surface Wb of the wafer W.

之後，晶圓W藉由晶圓搬送部25搬送至第2支撐台26b，藉由薄片切斷器28沿著晶圓W的外形使多餘的薄片F切斷。此時，薄片F的直徑至少大於晶圓W的直徑。 如此，如圖5所示，在晶圓W的背面Wb的整面形成包含樹脂層R及薄片F的保護構件P。保護構件P形成後，第1搬送機械臂21將具備保護構件P的晶圓W以正面Wa朝向上之方式，透過第1開口512容納於交接卡匣51。After that, the wafer W is transported to the second support table 26 b by the wafer transport unit 25, and the excess sheet F is cut along the outer shape of the wafer W by the sheet cutter 28. At this time, the diameter of the sheet F is at least larger than the diameter of the wafer W. In this way, as shown in FIG. 5, the protective member P including the resin layer R and the sheet F is formed on the entire surface of the back surface Wb of the wafer W. After the protective member P is formed, the first transfer robot 21 stores the wafer W provided with the protective member P in the transfer cassette 51 through the first opening 512 with the front side Wa facing upward.

藉由保護構件形成裝置2形成保護構件P後，研削裝置3研削晶圓W的正面Wa。 在如圖6所示的研削裝置3中，首先，第2搬送機械臂31將具備交接卡匣部5內的保護構件P的晶圓W，透過第2開口513取出。第2搬送機械臂31將晶圓W以正面Wa朝向上之方式載置於暫置台32。並且，第1搬送手段313a將晶圓W的正面Wa吸附保持，並搬送至定位於搬出入區域A的卡盤台302。卡盤台302吸附保持在晶圓W的背面Wb形成的保護構件P。藉此，在露出正面Wa的狀態下，晶圓W保持於卡盤台302。After the protective member P is formed by the protective member forming apparatus 2, the grinding apparatus 3 grinds the front surface Wa of the wafer W. In the grinding apparatus 3 shown in FIG. 6, first, the second transfer robot 31 takes out the wafer W provided with the protective member P in the delivery cassette part 5 through the second opening 513. The second transfer robot 31 places the wafer W on the temporary table 32 with the front Wa facing upward. In addition, the first transport means 313a sucks and holds the front surface Wa of the wafer W, and transports it to the chuck table 302 positioned in the carry-out area A. The chuck table 302 sucks and holds the protective member P formed on the back surface Wb of the wafer W. Thereby, the wafer W is held on the chuck table 302 in a state where the front surface Wa is exposed.

接著，保持晶圓W的卡盤台302從搬出入區域A到在加工區域B內設置的研削手段303的研削輪334的下方移動。並且，使卡盤台302旋轉，並一同使具有研削磨石340的研削輪334旋轉。進而，研削進給手段306將研削手段303運送至下方，藉此，旋轉的研削磨石340接觸晶圓W的正面Wa，研削正面Wa。當晶圓W被研削至預定的厚度時，則研削進給手段306使研削手段303上升，並結束研削。Next, the chuck table 302 holding the wafer W moves from the carry-in/out area A to below the grinding wheel 334 of the grinding means 303 provided in the processing area B. Then, the chuck table 302 is rotated, and the grinding wheel 334 having the grinding stone 340 is rotated together. Furthermore, the grinding feeding means 306 conveys the grinding means 303 downward, whereby the rotating grinding stone 340 contacts the front surface Wa of the wafer W and grinds the front surface Wa. When the wafer W is ground to a predetermined thickness, the grinding feed means 306 raises the grinding means 303, and the grinding ends.

研削結束後，卡盤台302移動至搬出入區域A，第2搬送手段313b吸附保持晶圓W的正面Wa，將晶圓W搬送至旋轉清洗單元350。After the grinding is completed, the chuck table 302 moves to the carry-in area A, the second transport means 313b sucks and holds the front Wa of the wafer W, and transports the wafer W to the spin cleaning unit 350.

旋轉清洗單元350具有：配在中央的旋轉台352、從旋轉台352在徑方向延伸的4個邊緣夾具351、使旋轉台352及邊緣夾具351旋轉的旋轉手段354、以及將Z軸方向作為旋轉軸而可旋轉的清洗噴嘴353。4個邊緣夾具351是以例如大致90度的角度間隔安裝於旋轉台352。The rotating cleaning unit 350 has a rotating table 352 arranged in the center, four edge clamps 351 extending in the radial direction from the rotating table 352, a rotating means 354 that rotates the rotating table 352 and the edge clamps 351, and the Z-axis direction as a rotation A cleaning nozzle 353 that can rotate on a shaft. The four edge clamps 351 are mounted on the rotating table 352 at an angular interval of approximately 90 degrees, for example.

在晶圓W的正面Wa的研削後的清洗，旋轉台352吸附保持由第2搬送手段313b所搬送的晶圓W的背面Wb。之後，旋轉手段354使旋轉台352高速旋轉，藉此晶圓W會高速旋轉。並且，從清洗噴嘴353朝向晶圓W的正面Wa噴射清洗水，使正面Wa清洗。In the cleaning after grinding of the front surface Wa of the wafer W, the turntable 352 sucks and holds the back surface Wb of the wafer W conveyed by the second conveying means 313b. After that, the rotating means 354 rotates the rotating table 352 at a high speed, whereby the wafer W is rotated at a high speed. Then, cleaning water is sprayed from the cleaning nozzle 353 toward the front surface Wa of the wafer W to clean the front surface Wa.

使清洗水的噴射停止後，藉由旋轉手段354維持晶圓W的高速旋轉，藉此使晶圓W乾燥。此時，亦可從未圖示的空氣用噴嘴向晶圓W噴射高壓空氣。乾燥結束後，解除旋轉台352對晶圓W的吸附，成為僅將晶圓W載置於旋轉台352的狀態。使該晶圓W被搬送至剝離裝置4。After stopping the spray of the washing water, the high-speed rotation of the wafer W is maintained by the rotation means 354, thereby drying the wafer W. At this time, high-pressure air may be injected to the wafer W from an air nozzle (not shown). After the drying is completed, the suction of the wafer W by the turntable 352 is released, and only the wafer W is placed on the turntable 352. The wafer W is transferred to the peeling device 4.

如圖7所示，剝離裝置4保持晶圓W，並具備用來搬送的保持手段42。保持手段42具備：吸附保持晶圓W的保持墊421、支撐保持墊421的臂部420、支撐臂部420並在Z軸方向來回移動的Z軸方向移動手段413、支撐Z軸方向移動手段413的可動板429、及使可動板429在X軸方向來回移動的X軸方向移動手段412。As shown in FIG. 7, the peeling apparatus 4 holds the wafer W, and is equipped with the holding means 42 for conveyance. The holding means 42 includes a holding pad 421 for sucking and holding the wafer W, an arm portion 420 that supports the holding pad 421, a Z-axis direction moving device 413 that supports the arm portion 420 and moving back and forth in the Z-axis direction, and a supporting Z-axis direction moving device 413 The movable plate 429 and the X-axis direction moving means 412 that move the movable plate 429 back and forth in the X-axis direction.

保持手段42是相當於第2搬送機構及第3搬送裝置的一例，其中第2搬送機構將具備保護構件P的晶圓W從研削裝置3搬送至剝離裝置4，第3搬送裝置則將剝離了保護構件P的晶圓W從剝離裝置4搬送至研削裝置3。The holding means 42 is equivalent to an example of the second transfer mechanism and the third transfer device. The second transfer mechanism transfers the wafer W provided with the protective member P from the grinding device 3 to the peeling device 4, and the third transfer device peels it off. The wafer W of the protective member P is transported from the peeling device 4 to the grinding device 3.

在剝離裝置4中，首先，保持手段42的保持墊421藉由X軸方向移動手段412及Z軸方向移動手段413，移動至相鄰剝離裝置4的圖6所示之研削裝置3的旋轉清洗單元350。並且，保持墊421將載置於旋轉清洗單元350的晶圓W的正面Wa吸附保持。In the peeling device 4, first, the holding pad 421 of the holding means 42 is moved by the X-axis direction moving means 412 and the Z-axis direction moving means 413 to the rotary cleaning of the grinding device 3 shown in FIG. 6 adjacent to the peeling device 4 Unit 350. In addition, the holding pad 421 sucks and holds the front surface Wa of the wafer W placed on the spin cleaning unit 350.

之後，保持手段42以正面Wa為上側之方式，將晶圓W載置於保持台441上。保持台441吸附保持晶圓W，以Z軸方向作為旋轉軸而可旋轉。並且，保持台441及外側部分剝離手段443在多處（例如8處）從晶圓W的背面Wb僅剝離圖5所示之晶圓W的保護構件P的外側部分。此剝離後，解除保持台441對晶圓W的吸附。After that, the holding means 42 places the wafer W on the holding table 441 with the front surface Wa on the upper side. The holding table 441 sucks and holds the wafer W, and is rotatable with the Z-axis direction as a rotation axis. In addition, the holding table 441 and the outer part peeling means 443 peel only the outer part of the protective member P of the wafer W shown in FIG. 5 from the back surface Wb of the wafer W at a plurality of places (for example, 8 places). After peeling, the suction of the wafer W by the holding table 441 is released.

接著，保持手段42將保持台441上的晶圓W藉由保持墊421吸附，搬送至晶圓W的整體剝離手段43的上方的位置，並固定在此位置。Next, the holding means 42 sucks the wafer W on the holding table 441 by the holding pad 421, transports it to a position above the whole peeling means 43 of the wafer W, and fixes it at this position.

整體剝離手段43包含：把持部431，以及使把持部431沿著X軸方向移動的移動構件432。把持部431把持在晶圓W的保護構件P 之-X側被剝離的外側部分。在這狀態下，移動構件432使把持部431在+X側移動。因為晶圓W的位置被固定，藉由把持保護構件P的把持部431的移動，如圖8所示，從晶圓W的背面Wb使保護構件P剝離。被剝離的保護構件P落下於圖7所示的盒體479。The whole peeling means 43 includes a grip portion 431 and a moving member 432 that moves the grip portion 431 in the X-axis direction. The gripping portion 431 grips the outer portion of the protective member P of the wafer W that is peeled off on the −X side. In this state, the moving member 432 moves the grip 431 to the +X side. Because the position of the wafer W is fixed, the movement of the grip 431 that grips the protection member P causes the protection member P to be peeled off from the back surface Wb of the wafer W as shown in FIG. 8. The peeled protective member P falls on the box body 479 shown in FIG. 7.

另外，剝離裝置4具備用來清洗晶圓W的外周部分之外周清洗裝置6。保持手段42將剝離了保護構件P的晶圓W搬送至外周清洗裝置6。In addition, the peeling device 4 includes an outer peripheral cleaning device 6 for cleaning the outer peripheral portion of the wafer W. The holding means 42 transports the wafer W from which the protective member P has been peeled to the peripheral cleaning device 6.

如圖9（a）所示，保持手段42將藉由保持墊421吸附保持的晶圓W以正面Wa朝向上之方式，載置於外周清洗裝置6的保持台63上。保持台63吸附保持晶圓W的背面Wb。As shown in FIG. 9( a ), the holding means 42 places the wafer W sucked and held by the holding pad 421 on the holding table 63 of the peripheral cleaning device 6 with the front side Wa facing upward. The holding table 63 sucks and holds the back surface Wb of the wafer W.

保持台63被支撐於沿著導軌65可移動的可動塊體64。導軌65的+X側的端部配有清洗盒體67。另外，導軌65是藉由設在-X側的端部之傾斜手段66，構成為可在箭頭C方向傾斜。The holding table 63 is supported by a movable block 64 that is movable along the guide rail 65. A cleaning box 67 is provided at the end of the guide rail 65 on the +X side. In addition, the guide rail 65 is configured to be tiltable in the arrow C direction by the tilting means 66 provided at the end on the -X side.

保持台63保持晶圓W後，支撐保持台63之可動塊體64沿著導軌65在+X方向移動。這個結果如圖9（b）所示，晶圓W的外周部分會通過設在清洗盒體67之晶圓進入口671，被上下一對的海綿672夾持。這種狀態下，保持台63會旋轉並且同時從清洗水噴嘴673相對於海綿672噴出水。藉此，晶圓W的外周部分藉由海綿672清洗。After the holding table 63 holds the wafer W, the movable block 64 supporting the holding table 63 moves in the +X direction along the guide rail 65. This result is shown in FIG. 9(b). The outer peripheral portion of the wafer W passes through the wafer inlet 671 provided in the cleaning box 67 and is clamped by the upper and lower pair of sponges 672. In this state, the holding table 63 rotates and simultaneously sprays water from the washing water nozzle 673 relative to the sponge 672. Thereby, the outer peripheral portion of the wafer W is cleaned by the sponge 672.

從清洗水噴嘴673供給並在海綿672吸收的清洗水，是從海綿672滲出落下並滯留在清洗盒體67內。為了排出此水，傾斜手段66如圖9（c）所示，使導軌65在清洗盒體67下降的方向上傾斜。這種結果，清洗盒體67所滯留的清洗水從設在清洗盒體67的+X方向側之排水口674被排出。另外，充滿於清洗盒體67的清洗水的水蒸氣藉由設在清洗盒體67的+X方向側之氣液分離裝置675，被分離為氣體和水。被分離的水從排水口674被排出，氣體從排氣口676被排出。The washing water supplied from the washing water nozzle 673 and absorbed in the sponge 672 oozes and drops from the sponge 672 and stays in the washing box 67. In order to discharge this water, the tilting means 66 tilts the guide rail 65 in the direction in which the washing box 67 descends as shown in FIG. 9(c). As a result, the washing water retained in the washing box 67 is discharged from the drain port 674 provided on the +X direction side of the washing box 67. In addition, the water vapor of the washing water filled in the washing box 67 is separated into gas and water by a gas-liquid separator 675 provided on the +X direction side of the washing box 67. The separated water is discharged from the drain 674, and the gas is discharged from the exhaust 676.

晶圓W的外周部分的清洗結束後，導軌65回到水平，並且可動塊體64以晶圓W的整體從清洗盒體67移出之方式在-X方向移動。之後，解除保持台63對晶圓W的吸附，圖7所示的剝離裝置4的保持手段42是藉由保持墊421吸附保持在保持台63上的晶圓W。並且，保持手段42將晶圓W搬送至圖6所示之研削裝置3，並在該旋轉清洗單元350的旋轉台352，以正面Wa朝向上之方式載置晶圓W。After the cleaning of the outer peripheral portion of the wafer W is completed, the guide rail 65 returns to the horizontal, and the movable block 64 moves in the −X direction in such a manner that the entire wafer W is removed from the cleaning box 67. After that, the suction of the wafer W by the holding table 63 is released, and the holding means 42 of the peeling device 4 shown in FIG. 7 sucks and holds the wafer W on the holding table 63 by the holding pad 421. In addition, the holding means 42 transports the wafer W to the grinding apparatus 3 shown in FIG. 6, and the wafer W is placed on the turntable 352 of the rotary cleaning unit 350 with the front Wa facing upward.

當在旋轉台352載置晶圓W時，第2搬送機械臂31將旋轉台352上的晶圓W吸附保持，反轉，並以背面Wb朝向上之方式將晶圓W載置於暫置台32。 再者，亦可為：第2搬送機械臂31在旋轉台352的上方待機，剝離裝置4的保持手段42將晶圓W交接至第2搬送機械臂31，吸引保持，反轉，並以背面Wb朝向上之方式將晶圓W載置於暫置台32。When the wafer W is placed on the turntable 352, the second transfer robot 31 sucks and holds the wafer W on the turntable 352, reverses it, and places the wafer W on the temporary table with the back side Wb facing upward. 32. Furthermore, the second transfer robot 31 may stand by above the turntable 352, and the holding means 42 of the peeling device 4 transfers the wafer W to the second transfer robot 31, sucks, holds, reverses, and returns The wafer W is placed on the temporary stage 32 with Wb facing upward.

之後，第1搬送手段313a將晶圓W的背面Wb吸附保持，並搬送至定位於搬出入區域A的卡盤台302。卡盤台302以露出晶圓W的背面Wb之方式將晶圓W的正面Wa吸附保持。After that, the first transport means 313a sucks and holds the back surface Wb of the wafer W, and transports it to the chuck table 302 positioned in the carry-in area A. The chuck table 302 sucks and holds the front surface Wa of the wafer W so that the back surface Wb of the wafer W is exposed.

接著，保持晶圓W的卡盤台302在研削輪334的下方移動，使卡盤台302及研削輪334旋轉並一同使包含研削輪334的研削手段303下降。藉此，與研削輪334一同旋轉的研削磨石340接觸晶圓W的背面Wb，使背面Wb被研削。當晶圓W研削至預定的厚度時結束研削。Next, the chuck table 302 holding the wafer W is moved below the grinding wheel 334, the chuck table 302 and the grinding wheel 334 are rotated, and the grinding means 303 including the grinding wheel 334 is lowered together. Thereby, the grinding stone 340 rotating together with the grinding wheel 334 contacts the back surface Wb of the wafer W, and the back surface Wb is ground. The grinding ends when the wafer W is ground to a predetermined thickness.

研削結束後，卡盤台302移動至搬出入區域A，解除晶圓W的吸附。並且，第2搬送手段313b吸附保持晶圓W的背面Wb，將晶圓W搬送至旋轉清洗單元350。After the grinding is completed, the chuck table 302 moves to the carry-in/out area A, and the suction of the wafer W is released. Then, the second conveying means 313 b sucks and holds the back surface Wb of the wafer W, and conveys the wafer W to the spin cleaning unit 350.

在晶圓W的背面Wb的研削後的清洗中，4個邊緣夾具351把持晶圓W的外周部分。之後，旋轉手段354使旋轉台352高速旋轉。藉此，安裝於旋轉台352的邊緣夾具351、及把持於邊緣夾具351的晶圓W亦高速旋轉。並且，從清洗噴嘴353朝向晶圓W的背面Wb噴射清洗水，並一同從旋轉台352的中央朝向晶圓W的正面Wa，向上噴射清洗水。藉此，一同清洗晶圓W的正面Wa及背面Wb。In the cleaning after grinding of the back surface Wb of the wafer W, the four edge clamps 351 grip the outer peripheral portion of the wafer W. After that, the rotating means 354 rotates the rotating table 352 at a high speed. Thereby, the edge clamp 351 installed on the rotating table 352 and the wafer W held by the edge clamp 351 are also rotated at a high speed. Then, the cleaning water is sprayed from the cleaning nozzle 353 toward the back surface Wb of the wafer W, and the cleaning water is sprayed upward from the center of the turntable 352 toward the front surface Wa of the wafer W. Thereby, the front Wa and back Wb of the wafer W are cleaned together.

使清洗水的噴射停止後，藉由旋轉手段354維持晶圓W的高速旋轉，藉此使晶圓W乾燥。乾燥結束後，藉由邊緣夾具351使晶圓W的把持解除，成為僅將晶圓W載置於旋轉台352的狀態。第2搬送機械臂31保持此晶圓，並容納於圖1所示的裝載埠LP。如此，使晶圓W的正面Wa及背面Wb的兩面研削，除去開始捲曲及翹曲等變形要素，獲得具有預定厚度的晶圓W。After stopping the spray of the washing water, the high-speed rotation of the wafer W is maintained by the rotation means 354, thereby drying the wafer W. After the drying is completed, the grip of the wafer W is released by the edge clamp 351, and only the wafer W is placed on the turntable 352. The second transfer robot 31 holds the wafer and is accommodated in the load port LP shown in FIG. 1. In this way, both the front surface Wa and the back surface Wb of the wafer W are ground to remove deformation elements such as initial curling and warping, and a wafer W having a predetermined thickness is obtained.

如以上所述，在晶圓製造裝置1中，藉由第1搬送機械臂21、交接卡匣部5及第2搬送機械臂31，可將具備保護構件P的晶圓W從保護構件形成裝置2搬送至研削裝置3。進而，藉由剝離裝置4的保持手段42，可將正面Wa被研削並在背面Wb具備保護構件P的晶圓W從研削裝置3搬送至剝離裝置4。並且，藉由保持手段42，可將剝離了保護構件P的晶圓W從剝離裝置4搬送至研削裝置3。As described above, in the wafer manufacturing apparatus 1, the first transfer robot 21, the delivery cassette section 5, and the second transfer robot 31 can transfer the wafer W provided with the protective member P from the protective member forming device 2Transfer to grinding device 3. Furthermore, by the holding means 42 of the peeling device 4, the wafer W whose front Wa is ground and provided with the protective member P on the back Wb can be transported from the grinding device 3 to the peeling device 4. In addition, by the holding means 42, the wafer W from which the protective member P has been peeled can be transported from the peeling device 4 to the grinding device 3.

如此，在晶圓製造裝置1中，在保護構件形成裝置2與研削裝置3之間、及研削裝置3與剝離裝置4之間的晶圓W搬送，不必有操作員的介入。此結果，可減少晶圓W的製造步驟中操作員的作業工時。In this way, in the wafer manufacturing apparatus 1, the transfer of the wafer W between the protective member forming apparatus 2 and the grinding apparatus 3 and between the grinding apparatus 3 and the peeling apparatus 4 does not require the intervention of an operator. As a result, it is possible to reduce the working hours of the operator in the manufacturing step of the wafer W.

另外，在晶圓製造裝置1中，剝離裝置4包含外周清洗裝置6，進而，保持手段42在剝離裝置4與外周清洗裝置6之間搬送晶圓W。藉此，在剝離裝置4與外周清洗裝置6之間的晶圓W的搬送，因為不必有操作員的介入，故可進一步減少作業員的作業工時。In addition, in the wafer manufacturing apparatus 1, the peeling device 4 includes the outer peripheral cleaning device 6, and further, the holding means 42 transports the wafer W between the peeling device 4 and the outer peripheral cleaning device 6. Thereby, since the transfer of the wafer W between the peeling device 4 and the peripheral cleaning device 6 does not require the intervention of an operator, it is possible to further reduce the working hours of the operator.

另外，在本晶圓製造裝置1中，以在X方向排列之方式配置有保護構件形成裝置2、研削裝置3、及剝離裝置4，故晶圓的搬送方向單純化。因此，可將晶圓W搬送簡單化。In addition, in the wafer manufacturing apparatus 1 of the present invention, the protective member forming device 2, the grinding device 3, and the peeling device 4 are arranged so as to be aligned in the X direction, so that the conveying direction of the wafer is simplified. Therefore, the transfer of the wafer W can be simplified.

另外，在本晶圓製造裝置1中，研削裝置3含有旋轉清洗單元350，且保持手段42從旋轉台352將晶圓W搬送至剝離裝置4。因此，因為可在將保護構件P剝離前清洗晶圓W，故可藉由剝離裝置4適當實施保護構件P的剝離。In addition, in this wafer manufacturing apparatus 1, the grinding apparatus 3 includes a rotating cleaning unit 350, and the holding means 42 transports the wafer W from the rotating table 352 to the peeling apparatus 4. Therefore, since the wafer W can be cleaned before the protective member P is peeled off, the peeling device 4 can appropriately perform the peeling of the protective member P.

再者，在本實施方式中，如圖3所示，交接卡匣部5的交接卡匣51具備：保護構件形成裝置2側的第1開口512、及研削裝置3側的第2開口513，第1搬送機械臂21及第2搬送機械臂31透過該些開口相對於層架511將晶圓W送出搬入。Furthermore, in this embodiment, as shown in FIG. 3, the transfer cassette 51 of the transfer cassette portion 5 includes a first opening 512 on the side of the protective member forming device 2 and a second opening 513 on the side of the grinding device 3. The first transfer robot 21 and the second transfer robot 31 transport the wafer W into and out of the shelf 511 through these openings.

晶圓製造裝置1可具備圖10所示的交接卡匣部5a及控制手段7來代替這種交接卡匣部5。交接卡匣部5a在交接卡匣部5的構成中，在交接卡匣51及卡匣台座52之間具備使交接卡匣51繞Z軸周圍旋轉的旋轉器53。控制手段7控制旋轉器53，使交接卡匣51旋轉。The wafer manufacturing apparatus 1 may include the transfer cassette part 5a and the control means 7 shown in FIG. 10 instead of such a transfer cassette part 5. The delivery cassette part 5a has a rotator 53 between the delivery cassette 51 and the cassette base 52 in the configuration of the delivery cassette part 5 to rotate the delivery cassette 51 around the Z axis. The control means 7 controls the rotator 53 to rotate the transfer cassette 51.

在此構成中，因為交接卡匣51可旋轉，可將第1開口512或第2開口513朝向Y側。藉此，操作員無須透過保護構件形成裝置2或研削裝置3，亦可從交接卡匣部5的正表面（Y側）直接將晶圓W拔出。這種結果，舉例而言，操作員在保護構件形成裝置2或研削裝置3故障的情況，無須進入這些的裝置內，而可安全回收晶圓W。 另外，操作員確認在保護構件形成裝置2形成之保護構件P的狀態後，能夠放回交接卡匣51，往研削裝置3搬送並進行研削加工。如此形成之保護構件P的確認，是在將供給液狀樹脂的液狀樹脂槽交換時等所進行，在液狀樹脂槽的交換後直接確認形成的保護構件P是否有氣泡進入，若有氣泡進入的話則不可回到交接卡匣51，故可防止研削不良。In this configuration, since the transfer cassette 51 can be rotated, the first opening 512 or the second opening 513 can be directed toward the Y side. Thereby, the operator can directly pull out the wafer W from the front surface (Y side) of the delivery cassette portion 5 without going through the protective member forming device 2 or the grinding device 3. As a result, for example, when the protective member forming device 2 or the grinding device 3 fails, the operator does not need to enter these devices, and the wafer W can be safely recovered. In addition, after confirming the state of the protective member P formed by the protective member forming apparatus 2, the operator can put back the delivery cassette 51, transport it to the grinding apparatus 3, and perform grinding processing. The confirmation of the protective member P formed in this way is performed when the liquid resin tank supplied with the liquid resin is exchanged. After the liquid resin tank is exchanged, it is directly confirmed whether the formed protective member P has air bubbles. If you enter, you cannot return to the transfer cassette 51, so it can prevent poor grinding.
