間隔對向配置複數TFT(薄膜電晶體)形成矩陣狀之陣列基 板(TFT基板)、及形成有彩色濾光器或遮光膜等之彩色濾 光器基板(CF基板),於兩基板間封入液晶,並且以含光硬 化性樹脂之密封構件(接著劑將兩基板互相貼合而製 造。此外’該2片基板之貼合係於真空環境下進行,用以 防止不純氣體之混入等。 作為該類使2片基板貼合之裝置,據知有例如專利文獻i ❹ 之基板貼合裝置。專利文獻1之基板貼合裝置具備:真空 腔室,其係以上侧容器及下側容器所構成;上基板搬送治 具,其係用以使上基板移動;第一支持棒,其係用以使上 側容器上下移動;基座板,其係支持該支持棒;及第二支 持棒’其係用以使上基板搬送治具上下移動。 於上述基板貼合裝置,使第一支持棒往下方移動,上側 谷器與下側容器抵接而構成真空腔室,並且使第二支持棒 往下方移動,降下上基板搬送治具,使上基板與下基板對 向配置為特定間隔。其後,進行上基板與下基板之對準貼 135990.doc 200941614 合0 [專利文獻1]曰本特開2007-212572號公報 【發明内容】 [發明所欲解決之問題] 上述專利文獻1之貼合基板製造裝置係將處理室内抽取 • 真空後’進行上基板與下基板之對準,使該等2片基板貼 合。然而’於進行上基板與下基板之對準後,若藉由使基 座板所備有之第二支持棒移動來移動上基板搬送治具,則 ® 唯恐上基板與下基板之位置會相對地偏離。此係由於複數 構件介在基座板至下基板間,配置有下基板之下側容器與 第二支持棒所備有之基座板進行不同之運動所致β如此, 具有良率由於上基板與下基板之相對位置偏離而降低之問 題》 本發明係有鑑於上述事情所完成者,其所欲解決之問題 在於提供一種可提升2片基板之對準精度、提升良率之貼 φ 合基板製造裝置及貼合基板製造方法。 [解決問題之技術手段] 關於本發明之貼合基板製造裝置之特徵為:一面將上基 板與下基板對準一面貼合而製造貼合基板;且包含:基座 ,,其係載置前述下基板;支持棒,其係立設於該基座 部,及上加壓構件,其係可沿著該支持棒上下移動,且可 '、夺前述上基板,n纟使前述上加壓構件下%,以貼合由 ’述上加壓構件所保持之前述上基板與載置於前述基座部 之前述下基板。 135990.doc 200941614 根據上述貼合基板製造裝置,由於保持有上基板之上加 壓構件係由立設於載置有下基板之基座部之支持棒所導引 而上下移動,因此可將介在上基板與下基板間之構件數抑 制在最小限度。藉此,於進行上基板與下基板之對準後至 貼合為止之期間,可防止上基板與下基板之相對位置偏 離。其結果,因而有提升2片基板之對準精度、提升良率 之效果。 於前述上加壓構件及前述基座部之至少任一方,以圍繞 配置前述上基板或前述下基板之區域之方式設置有密封構 件;藉由使前述上加壓構件下降,以於前述密封構件、前 述上加壓構件及前述基座部間形成貼合處理室。 該情况下,由於能以上加壓構件、基座部及密封構件來 構成貼合處理室,因此可減少零件數。其結果,可將裝置 予以小型•輕量化。 進一步包含減壓機構,其係將前述貼合處理室之内部減 壓,藉由該減壓機構將前述貼合處理室減壓時,前述貼合 處理室由前述密封構件所密閉亦可。 該情況下,由於密封構件介裝於上加壓構件與基座部 間’將貼合處理室減壓時,可確實地密閉該貼合處理室。 因此,可4實地將貼合處理室減壓,可製造所需之貼合基 板。 前述基座部亦可包含:下基板吸附裝置,其係、一面吸附 前述下基板之一部分’―面使該下基板移動;及下基板浮 起吸附裝置’其係於藉由該下基板吸附裝置移動前述下基 135990.doc 200941614 板時,使該下基板浮起,並且於前述上基板與前述下基板 之貼合時,可吸附前述下基板之未由前述下基板吸附裝置 所吸附之部分。 該情況下,使上基板與下基板貼合時,可藉由下基板浮 起寻附裝置來使下基板吸附於基座部。因此,可防止下基 板之位置偏離^其結果,可精度良好地使上基板與下基板 貼合。而且,由於不另外需要用以載置下基板之台,因此 可減少介在基座部與下基板間之構件數。再者,若使下基 板吸附於基座部,則下基板吸附裝置及下基板浮起吸附裝 置不會露出於貼合處理室,因此可防止從各裝置所產生之 粒子等流入貼合處理室内。因此’可確保貼合處理室内之 潔淨度。 前述密封構件亦可包+:接合部,其係對於前述基座部 及前述上加壓構件之一方上下移動,構成前述貼合處理室 之壁部’及②、封件’其係設置於前述接合部,抵接於前述 基座部或前述上加壓構件以確保前述貼合處理室之氣密 性。 ’ 該情況下,由於接合部係對於基座部或上加壓構件上下 移動而構成貼合處理室之壁部,因此即使上加壓構件上 升’仍可將貼合處理室保持於㈣狀態。藉此,即使於分 離配置下基板與上基板以增大氣導之狀態仍可將貼合處 理室減壓,其結果可縮短減壓時間。 而且,關於本發明之貼合基板製造方法係於基座部栽置 下基板#由可沿著立設於前述基座部之支持棒上下移動 135990.doc 200941614 之上加壓構件來保持上基板,一面將前述下基板與前述上 基板對準一面貼合而製造貼合基板;且包含以下步稀:第 一下基板移動步驟,其係藉由設置於前述基座部之下基板 吸附裝置一面吸附前述下基板之一部分,一面使該下基板 從前述基座部分離,並且藉由設置於前述基座部之下基板 浮起吸附裝置使前述下基板浮起;上基板移動步驟其係 使前述上加壓構件下降,使前述下基板與前述上基板對向 配置為特定間隔;基板對準步驟,其係藉由前述下基板吸 附裝置使前述下基板移動,進行前述下基板與前述上基板 之對準;上加壓構件上升步驟,其係使前述上加壓構件上 升,將前述下基板與前述上基板配置為離開特定距離;處 理室形成步驟,其係藉由密封構件密閉前述上加壓構件與 前述基座部間,形成收容前述上基板及前述下基板之貼合 處理室;第二下基板移動步驟,其係藉由前述下基板吸附 裝置一面吸附前述下基板之一部分,一面使該下基板抵接 於前述基座部,並且藉由前述下基板浮起吸附裝置吸附前 述下基板之未由前述下基板吸附裝置所吸附之部分;減壓 步驟’其係將前述貼合處理室内減壓;及基板貼合步驟, 其係於密閉前述貼合處理室内之狀態,使前述上加壓構件 下降以貼合前述下基板與前述上基板。 根據上述貼合基板製造方法,由於保持有上基板之上加 壓構件係由立設於載置有下基板之基座部之支持棒所導引 而上下移動,因此可將介在上基板與下基板間之構件數抑 制在最小限度。藉此’於進行上基板與下基板之對準後至 135990.doc •12· 200941614 貼合為止之期間’可防止上基板與下基板之位置關係偏 離。因此’可提升2片基板之對準精度、提升良率。 而且’使上加壓構件上升,將下基板與上基板配置為離 開特疋距離後’對貼合處理室進行減壓,因此可於氣導大 之狀態下減壓。藉此,可縮短減壓時間。 再者,使上基板與下基板貼合時,可藉由下基板浮起吸 . 附裝置來使下基板吸附於基座部。因此,可防止下基板之 位置偏離,可精度良好地使上基板與下基板貼合。而且, 由於不另外需要用以載置下基板之台,因此可減少介在基 座部與下基板間之構件數。再者,若使下基板吸附於基座 部,則下基板吸附裝置及下基板浮起吸附裝置不會露出於 貼合處理室,因此可防止從各裝置所產生之粒子等流入貼 合處理室内。因此,可於確保貼合處理室内之潔淨度之狀 態下’使上基板與下基板貼合。 [發明之效果] 參 由於保持上基板之上加壓構件係由立設於載置有下基板 之基座部之支持棒所導引而上下移動,因此可將介在上基 板與下基板間之構件數抑制在最小限度。 藉此’於進行上基板與下基板之對準後至貼合為止之期 間’可防止上基板與下基板之位置關係偏離。因此,具有 提升2片基板之對準精度、提升良率之效果。 【實施方式】

Description of the Invention: TECHNICAL FIELD The present invention relates to a bonded substrate manufacturing apparatus and a bonded substrate manufacturing method. The present application claims priority based on Japanese Patent Application No. 2007-290912, the entire disclosure of which is incorporated herein. [Prior Art].  A flat panel display (FPD) such as a liquid crystal display or a plasma display includes a structure in which two substrates are bonded. For example, a liquid crystal display is a matrix substrate (TFT substrate) in which a plurality of TFTs (thin film transistors) are arranged to face each other at a level of several μm, and a color filter substrate on which a color filter or a light shielding film is formed ( In the CF substrate, a liquid crystal is sealed between the two substrates, and a sealing member containing a photocurable resin is used (the adhesive is used to bond the two substrates to each other. The bonding of the two substrates is performed in a vacuum environment, and the like) In order to prevent the incorporation of impure gas, etc., as a device for bonding two substrates, there is known a substrate bonding apparatus of Patent Document 1. The substrate bonding apparatus of Patent Document 1 includes a vacuum chamber. The upper substrate and the lower container are configured; the upper substrate transporting fixture is configured to move the upper substrate; the first support rod is configured to move the upper container up and down; and the base plate supports the support rod And a second support bar for moving the upper substrate transporting fixture up and down. In the substrate bonding apparatus, the first support bar is moved downward, and the upper side bar is abutted against the lower container. The vacuum chamber is opened, and the second support rod is moved downward, and the upper substrate is conveyed to lower the workpiece, so that the upper substrate and the lower substrate are opposed to each other at a specific interval. Thereafter, the alignment between the upper substrate and the lower substrate is performed. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2007-212572 [Drafts of the Invention] [Problems to be Solved by the Invention] The laminated substrate manufacturing apparatus of Patent Document 1 is obtained by extracting a treatment chamber and vacuuming The upper substrate and the lower substrate are aligned to bond the two substrates. However, after the alignment between the upper substrate and the lower substrate, if the upper substrate transporting jig is moved by moving the second support bar provided on the base plate, the position of the upper substrate and the lower substrate is opposed to each other. Deviate from the ground. This is because the plurality of members are disposed between the base plate and the lower substrate, and the bottom plate of the lower substrate and the base plate provided by the second support bar are arranged to perform different movements, so that the yield is due to the upper substrate and The problem that the relative position of the lower substrate is deviated and reduced. The present invention has been made in view of the above, and the problem to be solved is to provide a φ-bonded substrate which can improve the alignment accuracy and improve the yield of two substrates. Device and method of manufacturing a bonded substrate. [Means for Solving the Problem] The laminated substrate manufacturing apparatus of the present invention is characterized in that a bonded substrate is bonded while the upper substrate and the lower substrate are aligned with each other, and a pedestal is mounted thereon. a lower substrate; a support rod erected on the base portion, and an upper pressing member movable up and down along the support rod, and staking the upper substrate to nraw the upper pressing member The lower portion is bonded to the upper substrate held by the pressing member and the lower substrate placed on the base portion. 135990. Doc 200941614 According to the above-described bonded substrate manufacturing apparatus, since the pressing member on the upper substrate is held up and down by the support rod standing on the base portion on which the lower substrate is placed, it can be placed on the upper substrate. The number of members between the lower substrate and the lower substrate is suppressed to a minimum. Thereby, the relative position of the upper substrate and the lower substrate can be prevented from being deviated during the alignment between the upper substrate and the lower substrate and after bonding. As a result, there is an effect of improving the alignment accuracy of the two substrates and improving the yield. At least one of the upper pressing member and the base portion is provided with a sealing member so as to surround a region where the upper substrate or the lower substrate is disposed; and the upper pressing member is lowered to form the sealing member A bonding processing chamber is formed between the upper pressing member and the base portion. In this case, since the bonding processing chamber can be configured by the above pressing member, the base portion, and the sealing member, the number of parts can be reduced. As a result, the device can be reduced in size and weight. Further, the pressure reducing mechanism is configured to reduce the pressure inside the bonding processing chamber, and when the pressure reducing mechanism decompresses the bonding processing chamber, the bonding processing chamber may be sealed by the sealing member. In this case, when the sealing member is interposed between the upper pressing member and the base portion to decompress the bonding processing chamber, the bonding processing chamber can be reliably sealed. Therefore, the bonding processing chamber can be decompressed in a practical manner to manufacture a desired bonding substrate. The base portion may further include: a lower substrate adsorption device that adsorbs one of the lower substrate on one side to move the lower substrate; and a lower substrate floating adsorption device that is attached to the lower substrate adsorption device Move the aforementioned lower base 135990. In the case of the doc 200941614, the lower substrate is floated, and when the upper substrate and the lower substrate are bonded together, the portion of the lower substrate that is not adsorbed by the lower substrate adsorption device can be adsorbed. In this case, when the upper substrate and the lower substrate are bonded together, the lower substrate can be attracted to the base portion by the lower substrate floating the seek device. Therefore, it is possible to prevent the position of the lower substrate from being deviated, and as a result, the upper substrate and the lower substrate can be bonded with high precision. Further, since the stage for placing the lower substrate is not separately required, the number of members interposed between the base portion and the lower substrate can be reduced. Further, when the lower substrate is adsorbed to the base portion, the lower substrate adsorption device and the lower substrate floating adsorption device are not exposed to the bonding processing chamber, so that particles or the like generated from the respective devices can be prevented from flowing into the bonding processing chamber. . Therefore, it is possible to ensure the cleanliness of the processing chamber. The sealing member may include a joint portion that moves up and down one of the base portion and the upper pressing member, and the wall portion 'and the second member that constitutes the bonding processing chamber are provided in the foregoing The joint portion abuts against the base portion or the upper pressing member to ensure airtightness of the bonding processing chamber. In this case, since the joint portion moves up and down with respect to the base portion or the upper pressing member to constitute the wall portion of the bonding processing chamber, the bonding processing chamber can be held in the (four) state even if the upper pressing member is raised. Thereby, even if the substrate and the upper substrate are separated from each other to increase the air conduction state, the bonding processing chamber can be decompressed, and as a result, the decompression time can be shortened. Further, the method for manufacturing a bonded substrate according to the present invention is that the substrate is placed on the base portion. The substrate # is movable up and down along a support bar that is erected on the base portion. Doc 200941614 The upper pressing member holds the upper substrate, and the lower substrate is bonded to the upper substrate to form a bonded substrate; and the following steps are performed: a first lower substrate moving step, which is set by The substrate adsorbing device adsorbs one of the lower substrates on the lower surface of the base portion, and separates the lower substrate from the base portion, and the lower substrate is suspended by the substrate floating device disposed under the base portion. Floating; the upper substrate moving step of lowering the upper pressing member to face the lower substrate and the upper substrate at a specific interval; and the substrate aligning step of the lower substrate by the lower substrate adsorbing device Moving, performing alignment of the lower substrate and the upper substrate; and an upper pressing member ascending step of raising the upper pressing member to dispose the lower substrate and the upper substrate at a specific distance; and processing a chamber forming step Separating the upper pressing member from the base portion by a sealing member to form a fitting for accommodating the upper substrate and the lower substrate a second lower substrate moving step of abutting the lower substrate against the base portion while the lower substrate adsorbing device adsorbs one of the lower substrates, and the lower substrate floating adsorption device a portion of the lower substrate that is not adsorbed by the lower substrate adsorption device; a depressurization step of decompressing the bonding chamber; and a substrate bonding step of sealing the bonding chamber The upper pressing member is lowered to bond the lower substrate and the upper substrate. According to the method of manufacturing a bonded substrate, since the pressing member on the upper substrate is held up and down by the support rod standing on the base portion on which the lower substrate is placed, the upper substrate and the lower substrate can be placed. The number of members between the substrates is suppressed to a minimum. By this, the alignment between the upper substrate and the lower substrate is performed until 135990. Doc •12· 200941614 The period until the bonding can prevent the positional relationship between the upper substrate and the lower substrate from deviating. Therefore, the alignment accuracy of the two substrates can be improved and the yield can be improved. Further, when the upper pressing member is raised and the lower substrate and the upper substrate are disposed apart from each other, the bonding processing chamber is depressurized, so that the pressure can be reduced in a state where the air conduction is large. Thereby, the decompression time can be shortened. Furthermore, when the upper substrate and the lower substrate are bonded together, the lower substrate can be floated and sucked up.  A device is attached to adsorb the lower substrate to the base portion. Therefore, the positional deviation of the lower substrate can be prevented, and the upper substrate and the lower substrate can be bonded with high precision. Further, since the stage for placing the lower substrate is not separately required, the number of members interposed between the base portion and the lower substrate can be reduced. Further, when the lower substrate is adsorbed to the base portion, the lower substrate adsorption device and the lower substrate floating adsorption device are not exposed to the bonding processing chamber, so that particles or the like generated from the respective devices can be prevented from flowing into the bonding processing chamber. . Therefore, the upper substrate and the lower substrate can be bonded together while ensuring the cleanliness in the bonding processing chamber. [Effects of the Invention] Since the pressing member on the upper substrate is held up and down by the support rod standing on the base portion on which the lower substrate is placed, it can be interposed between the upper substrate and the lower substrate. The number of components is suppressed to a minimum. Thereby, the positional relationship between the upper substrate and the lower substrate can be prevented from deviating from the positional relationship between the upper substrate and the lower substrate. Therefore, it has the effect of improving the alignment accuracy of the two substrates and improving the yield.

Doc 17 200941614 A step portion 73 is formed between the lower surface of the upper pressing member 15 corresponding to the position of the support rod 13 (the both side portions 72 in the short side direction) and the other positions. The two sides Τ»卩72 are formed such that, for the base portion 11, the step portion η is located far away. At a position closer to the base portion u than the side portions 72, a holding surface 75 for holding the upper substrate W2 is formed. The peripheral portion of the holding surface is formed on the outer side of the concave portion 51 of the base portion 11 as viewed from the top.

When the upper substrate 2 to the bonded substrate manufacturing apparatus 1 is delivered from another device (not shown), the holding pin 79 is lowered, and the upper substrate W2 can be collected from the robot arm (not shown). After the upper substrate|2 is received, the holding pin 79 is raised and the electrostatic chuck head 77 is activated, whereby the upper substrate W2 can be held on the holding surface 75.

A camera arrangement portion 82 that penetrates the through hole of the upper pressing member 15 is formed. In summary, the camera 80 is mounted in the camera arrangement unit 82, and the camera 8 transmits the alignment marks M1 and m of the lower substrate W1 and the upper substrate W2 through the imaging unit _ to detect the deviation of the alignment marks ΜΙ and M2. Moreover, there is a control unit (not shown) which is photographed by the camera 8 135 135990. The doc • 18· 200941614 results are based on indicating the amount of movement in the horizontal plane for the first mobile device 31. (Operation) Next, the procedure for manufacturing the bonded substrate by the bonded substrate manufacturing apparatus ι will be described with reference to Figs. 4 to 9 . Further, Fig. 4 to Fig. 1G are explanatory views showing a process of manufacturing a bonded substrate by using a bonded substrate manufacturing apparatus; and Fig. 4 is a flow chart showing a process of manufacturing a bonded substrate. Further, each (four) number described later corresponds to the step number of Fig. 11. First, as shown in Fig. 4, the pressing member 15 is held in the state of the highest position on the bonded substrate manufacturing apparatus 1A. In step S, in this state, the robot substrate is carried into the lower substrate W1, and the specific loading method of the lower substrate is shown after the step. In step S2, the robot arm (not shown) is transported, and the lower substrate wi is placed above the base portion u. Here, the lift pin 45 is raised to float the lower substrate W1 from the robot arm. The robot arm is retracted from the chamber 17 in step S3'. In step S4, the lift pin 45 is lowered, and the lower substrate W1 is placed on the upper surface 23 of the base portion 11. In step S5, the lower substrate W1 is adsorbed to the drive table 25 by exhausting from the exhaust pipe 29, and the second moving device 32 provided on the base portion η is driven in step S6' to move the drive table 25 upward. Air is supplied to the air cushion 35 substantially simultaneously with step S6 in step S7', and air is ejected from the air hole 38 toward the lower substrate W1. As a result, the lower substrate|丨 is made up of 135990. Doc •19- 200941614 The drive table 25 is lifted up to the center of the center, and the peripheral portion of the lower substrate wi is lifted by the gas extraction action. In this manner, the lower substrate W1 is maintained in a horizontal state (first lower substrate moving step). At this time, the lower substrate is ejected from the upper surface 23 of the base portion 11 by several tens of μm. In step S8, the robot arm (not shown) is conveyed, and the upper substrate W2' is disposed below the holding surface 75 of the upper pressing member 丨5. The holding pin 79 is lowered in step S9' to adsorb the upper substrate W2. In step S10, the robot arm is retracted from the chamber 17. In step S11, the holding pin 79 is raised. In step S12', the electrostatic chuck portion 77 is made to function, and the upper substrate %2 is attracted to the holding surface 75. Fig. 5 is an explanatory diagram when the above step S12 is completed. Further, the steps of the steps S1 to S5 for loading the lower substrate W1 and the steps for moving the upper substrate W2 for the steps S8 to S12 may be preceded. Here, since the upper substrate W2 is dropped from the adsorption pin 57, the influence of the falling of the upper substrate W2 and the lower substrate W1 can be prevented by the first loading of the upper substrate W2. In particular, in the case of manufacturing a liquid crystal panel, since the liquid crystal is coated on the upper substrate W1, it is preferable to carry in the upper substrate W2 first. Next, in step S13, as shown in FIG. 6, the drive shaft 65 is driven while the lower substrate W1 is horizontal, and the upper pressing member 15 is lowered toward the base portion 11 (lower substrate W1) (upper substrate moving step) . At this time, the shaft portion 67 rotates in accordance with an instruction from the driving source 66, and the shaft portion 67 is thereby lowered. Since the upper pressing member 15 is supported by the shaft portion 67, it is simultaneously lowered. Further, since the support rod 13 is inserted into the guide guides 83 at the four corners of the upper pressing member 15, the upper pressing member 15 is lowered as it is in the horizontal state. Then, make up 135990. Doc • 20· 200941614 The pressing member 15 is lowered to a specific interval between the lower substrate W and the upper substrate W2. In step S14, as shown in FIG. 7, when the lower substrate W1 and the upper substrate arm 2 are at a certain interval (a few hundred μm), the camera 8 is operated, and the alignment marks M1 of the lower substrate W1 and the upper substrate W2 are The M2 is shot in focus. Then, the lower substrate W1 is moved in the horizontal direction to align the marks respectively.  Consistent (substrate alignment step). At this time, based on the amount of deviation of the alignment marks, the first moving means 31 is driven to move the drive table 25 in the horizontal direction to move the lower substrate W1 to an appropriate position. Further, when the alignment between the lower substrate W1 and the upper substrate W2 is performed, the holding surface 75 abuts against the joint portion 57 of the sealing member 55. In short, the chamber 17 that is hermetically sealed by the base portion 11, the upper pressing member 15, and the sealing member 55 is formed (process chamber forming step). Specifically, if the upper pressing member 15 presses the joint portion 57, Then, the joint portion 57 presses the tube 56 and the release valve (not shown) is connected to the tube 56. Therefore, the tube 56 is contracted while the internal pressure is kept constant. By this, it is possible to prevent breakage of the official member 56 while maintaining the sealed state of the upper pressing member 15 and the engaging portion 57. In step S15, as shown in FIG. 8, if the alignment of the lower substrate W1 and the upper substrate W2 is completed, 'the driving stage 25 of the lower substrate W1 is lowered, and the air supply of the air cushion 35 is stopped', the lower substrate wi is lowered to the base portion. u above 23. Then, the air is vented from the air cushion 35, and the lower substrate W1 is attracted to the upper surface 23 so that the position does not deviate (the second lower substrate moving step). Thereafter, the upper pressing member 15 is slightly moved upward (the upper pressing member is raised step). ). Thus, the distance between the lower substrate W1 and the upper substrate W2 is increased in comparison with the alignment. This is for the cavity to be carried out 135990. Doc •21· 200941614 During vacuum extraction in chamber 17, 'increase air conduction' shortens the vacuum extraction time and reliably vents air between substrates W1 and W2. Therefore, even when the upper pressing member 15 is slightly moved upward, the holding surface 75 is surely abutted against the engaging portion 57. Specifically, in contrast to the above, in a state where the internal pressure is kept constant, the tube 56 is expanded, and the sealed state of the upper pressing member 15 and the joint portion 57 can be maintained. In general, the position of the upper surface 58 of the engaging portion 57 is adjusted by adjusting the air pressure of the tube 56 of the sealing member 55. Moreover, even if the joint portion 57 is lifted and lowered, the airtightness in the chamber 17 is maintained by the seal member 61. Further, the upper pressing member 15 may be raised and then the lower substrate W1 may be lowered to the upper surface 23 of the base portion 11. Further, the processing chamber forming step may be performed after the step of raising the upper pressing member. The vacuum pump 49 is caused to evacuate the inside of the chamber 17 from the exhaust port 47 in step S16' (decompression step, and then the chamber 17 is kept in a vacuum state (about 0-4 Pa or less). In the step S17' chamber After the vacuum extraction in 17 is completed, the upper pressing member 15 is lowered again. In step S18, as shown in Fig. 9, the lower substrate W1 and the upper substrate W2 are bonded together (substrate bonding step). The weight of the pressing member 15 is pressed by the two substrates W1, W2. Here, the loading unit 69 is disposed between the front end portion 68 of the shaft portion 67 and the both side portions 72 of the upper pressing member 15. When the load applied to the two substrates W1 and W2 is detected, the substrate is adjusted to be bonded to the appropriate load. In step S19, as shown in FIG. 10, if the bonding between the lower substrate W1 and the upper substrate W2 is completed, the upper substrate is added. The pressing member 15 is raised. At this time, the bonding substrate W3 135990 is made. Doc -22- 200941614 is disposed on the base portion 11. In short, the function of the electrostatic chuck portion 77 of the upper pressing member 15 is released, and the upper substrate W2 is separated from the upper pressing member 15". In step S20, the lifting pin 45 of the base portion 11 is raised to make the fitting. The substrate W3 rises from the upper surface 23. In step S21', between the bonded substrate W3 and the upper surface 23 of the base portion 11, a robot arm is inserted, and the bonded substrate W3 is delivered from the lift pin 45 to the robot arm. Then, the robot arm transports the bonded substrate W3 to another device not shown, and the processing is completed. In the present embodiment, the bonded substrate manufacturing apparatus 10' for manufacturing the bonded substrate W3 is formed by aligning the upper substrate W2 and the lower substrate W1 on one surface, and the base portion 11 is mounted thereon. a lower substrate W1; a support rod 13' is erected on the base portion; and an upper pressing member 15 which is movable up and down along the support rod 13 and configured to hold the upper substrate W2; The upper pressing member 15 is lowered 'to fit the upper substrate 2 and the lower substrate W1. Therefore, the holding member 15 on the upper substrate W2 is held up and down by the support rod 13 which is erected on the base portion of the lower substrate. In summary, the number of components between the upper substrate 2 and the lower substrate is minimized. Thereby, the relative positional deviation between the upper substrate 2 and the lower substrate can be prevented during the alignment of the upper substrate 琛2 and the lower substrate 丨 to the bonding. Therefore, the alignment accuracy and the improvement of the yield of the two substrates W1 and 12 can be improved. Further, in the laminated substrate manufacturing apparatus 1 of the present embodiment, the base portion 11 is disposed around the lower substrate. The area is provided with a sealing member 55, by lowering the upper pressing member 〖5 to seal the member Η, upper 135990. Doc • 23· 200941614 A chamber 17 is formed between the pressurizing member 15 and the base portion 11. Therefore, the cavity 17' can be formed by the above pressing member 15, the base portion 11, and the sealing member 55, and the number of parts can be reduced. Therefore, the device can be made small and lightweight. Further, the laminated substrate manufacturing apparatus 1 of the present embodiment further includes a vacuum pump 49 for decompressing the inside of the chamber 17; when the chamber 17 is decompressed by the vacuum pump 49, the chamber 17 is sealed. The member 55 is sealed. Thus, when the sealing member 55 is interposed between the upper pressing member 15 and the base portion 11 to decompress the chamber 17, the chamber 17 can be reliably sealed. Therefore, the chamber 17 can be reliably decompressed, and the desired bonded substrate W3 can be manufactured. Further, the base portion 11 is provided with a driving table 25 that moves one side of the lower substrate W1 while moving the lower substrate wi, and a gas cylinder 35 that is moved by the driving table 25 to move the lower substrate W1. When the lower substrate W1 is floated' and the upper substrate W2 is bonded to the lower substrate W1, the lower substrate W1 can be adsorbed. Therefore, when the upper substrate W2 and the lower substrate W1 are bonded together, the lower substrate W1 can be adsorbed to the base portion 11 by the gas cylinder 35. Therefore, it is possible to prevent the positional deviation of the substrate boundary 1 from being caused, and it is possible to accurately bond the upper substrate W2 and the lower substrate W1. Further, since the stage for placing the lower substrate W1 is not separately required, the number of parts interposed between the base portion 11 and the lower substrate W1 can be reduced. Further, when the lower substrate W1 is adsorbed to the base portion, the drive table 25 and the air cushion 35 are not exposed to the chamber 17, and therefore it is possible to prevent particles or the like generated from the respective devices from flowing into the chamber 17. Therefore, the cleanliness in the chamber 17 can be ensured. 135990. Doc • 24-200941614 Then, the sealing member 55 includes a joint portion 57 that moves up and down with respect to the base portion 11 to form a wall portion of the chamber 17, and a seal member 52 that is provided at the joint portion 57 to abut The upper pressing member 15 is used to ensure the airtightness of the chamber 17. Therefore, the joint portion 57 moves up and down with respect to the base portion 11 to constitute the wall portion of the chamber 17, and even if the upper pressing member 15 rises, the sealed chamber 17 can be constructed. Thereby, even if the substrate W1 and the upper substrate Jia 2 are separated and disposed to increase the state of the air conduction, the inside of the chamber 17 can be decompressed, and the decompression time can be shortened. Further, other aspects of the sealing member 55 of the present embodiment are shown in Fig. 12. As shown in Fig. 12, the sealing member 255 is provided in the recess 51, and includes an air supply portion 256 formed below the recess portion 51 and a joint portion 57 disposed above the air supply portion 256. By changing the air pressure of the air supply unit 256, the joint portion 57 can move up and down along the side surface 60 of the recess 51, and can follow the movement of the upper pressing member 15, and the upper surface 58 of the joint portion 57 is closer to the upper surface of the base portion 11 Located above. Further, a seal 52 that seals between the upper pressing member 15 is provided on the upper surface 58 of the joint portion 57. Further, between the side surface 59 of the joint portion 57 and the side surface 60 of the recess portion 51 of the base portion 11, two seal members 6 1 for sealing therebetween are provided. A space portion 263 between the seal members 61 and 61 is connected to a communication pipe (not shown) that communicates with the outside (atmosphere). Thereby, the pressure load on the seal 61 can be alleviated. Further, on the side opposite to the seal member 61, a seal member 262 for blocking the air supply portion 256 from the outside (atmosphere) is provided. Thereby, the sealing member 255 can obtain substantially the same operational effects as the above-described sealing member 55. (Second embodiment) 135990. Doc -25- 200941614 Next, a bonded substrate manufacturing apparatus according to a second embodiment of the present invention will be described based on Fig. 13 . The present embodiment is different from the first embodiment only in the configuration of the sealing member, and the same reference numerals are given to the same portions, and the detailed description is omitted. Figure 13 is a structural view of a sealing member. As shown in FIG. 13, the sealing member ι55 is provided on the side of the upper pressing member 15. Specifically, a recess 1515 is formed in the holding surface 75 of the upper pressing member 15. The concave portion ι51 is formed at a position substantially opposite to the concave portion 51 of the first embodiment. A sealing member 155 is provided in the recess 151. The sealing member 155 includes a spring 156' disposed at the bottom of the recess 151, and a joint portion 157 disposed above the spring 156. The contraction portion 157 is moved up and down by the contraction of the spring 156. Further, a seal member 164 is provided on the front end surface 162 of the joint portion 157. Further, a side seal 161 is provided between the side surface 159 of the joint portion 157 and the side surface 160 of the recess portion 151. A stopper 165 is erected from the side surface 160 of the recess 151 toward the side surface 159 of the joint portion 157 so that the joint portion 157 does not fall from the recess portion 151. Thereby, the chamber 17 can be constituted by the base portion u, the upper pressing member 15, and the sealing member 155. (Operation) Before the substrate is bonded (in the initial state of the device), the joint portion 157 is suspended downward by the biasing force and the weight of the spring 156, and is engaged by the stopper π. When the upper pressing member 15 is lowered in order to bond the substrates, the upper substrate W2 is simultaneously lowered. As a result, the sealing member 164 of the engaging portion 157 abuts against the upper surface 23 of the base portion 1 1 , and the base portion 11 , the upper pressing member 15 and the sealing member 155 constitute the chamber 17 . Thereafter, if the upper pressing member 15 is further lowered, 135990. Doc • 26- 200941614 The spring 156 is contracted, and the joint portion 157 is housed in the recess 151. Thereafter, even if the upper pressing member 15 is slightly raised and lowered, the biasing force of the spring 156 acts to hold the sealing member 164 in contact with the upper surface 23 of the base portion 11. Therefore, when the substrates W1 and W2 are bonded together, the chamber I7 can be reliably formed, and the desired bonded substrate W3 can be manufactured. Further, in order to take the upper substrate W2 and the bonded substrate W3 from the chamber 17 by the robot arm, the sealing member 155 is disposed so as not to interfere. Further, if the joint portion 157 can be moved downward only by its own weight, the sealing member 155 may not be provided with the projecting 156. In this case, since the raising and lowering mechanism of the joint portion 157 is not required, the number of parts can be reduced, and as a result, the apparatus can be manufactured without cost. Further, when the substrate is picked up and lowered, the robot arm is picked up and lowered, so that the upper pressing member 15 rises to the extent that the joint portion 157 does not hinder. In addition, the technical scope of the present invention is not limited to the above-described embodiments, and various modifications are possible in the above-described embodiments without departing from the scope of the present invention. In other words, the specific shape, configuration, and the like of the embodiment may be changed as appropriate. For example, in the present embodiment, a tube or a spring is used to move the joint portion up and down. However, an actuator or the like may be used. Further, in the present embodiment, the case where the camera is attached to the upper pressing member is described, but the base portion may be provided. [Industrial Applicability] A bonded substrate manufacturing apparatus and a bonded substrate manufacturing method capable of improving the alignment accuracy of two substrates and improving the yield can be provided. 135990.
