Description

本発明は、露光等の加工処理される基板を保持するワークステージに係わり、特に、反りが生じているウエハ等の基板(ワーク)を吸着保持することのできるワークステージ、及び該ワークステージを使った露光装置に関する。   The present invention relates to a work stage for holding a substrate to be processed such as exposure, and in particular, a work stage capable of sucking and holding a substrate (work) such as a warped wafer, and the work stage. The present invention relates to an exposure apparatus.

従来、半導体、プリント基板、液晶基板等(以下ワークとも呼ぶ)を製造する工程において、露光等の加工処理を行う際、ワークが位置ずれを起こさないように、ワークを吸着保持するワークステージが使われる。   Conventionally, in the process of manufacturing a semiconductor, a printed circuit board, a liquid crystal substrate, etc. (hereinafter also referred to as a work), a work stage that holds and holds the work is used to prevent the work from being displaced when performing processing such as exposure. Is called.

図8は、従来技術に係るワークを吸着保持するワークステージを備えた露光装置の一例を示す図である。
同図に示すように、この露光装置100は、紫外線を出射する光照射部101、パターンが形成されたマスク102、マスク102を保持するマスクステージ103、レジストが塗布されているウエハやプリント基板等のワーク104を保持するワークステージ105、ワークステージ105上に保持されたワーク104上にマスク102のパターン像を投影する投影レンズ106等から構成される。なお、露光装置100中に、投影レンズ106を備えないものもある。更に、光照射部101は、紫外線を含む光を放射するランプ1011と、ランプ1011からの光を反射するミラー1012を備えている。また、ワークステージ105の表面には、真空吸着溝(または複数の真空吸着孔)1051が形成されている。ワークステージ105には配管1052が接続され、配管1052を介して、真空吸着孔(真空吸着溝)1051に、ワーク104を保持する際には真空が、またワーク104をワークステージ105から取外す際にはエアーが供給される。
FIG. 8 is a view showing an example of an exposure apparatus provided with a work stage for sucking and holding a work according to the prior art.
As shown in the figure, the exposure apparatus 100 includes a light irradiation unit 101 that emits ultraviolet rays, a mask 102 on which a pattern is formed, a mask stage 103 that holds the mask 102, a wafer or a printed circuit board on which a resist is applied, and the like. The workpiece stage 105 that holds the workpiece 104, the projection lens 106 that projects the pattern image of the mask 102 onto the workpiece 104 held on the workpiece stage 105, and the like. Note that some exposure apparatuses 100 do not include the projection lens 106. Further, the light irradiation unit 101 includes a lamp 1011 that emits light including ultraviolet rays, and a mirror 1012 that reflects light from the lamp 1011. A vacuum suction groove (or a plurality of vacuum suction holes) 1051 is formed on the surface of the work stage 105. A pipe 1052 is connected to the work stage 105. When holding the work 104 in the vacuum suction hole (vacuum suction groove) 1051 via the pipe 1052, a vacuum is applied, and when removing the work 104 from the work stage 105. Air is supplied.

この露光装置の動作を以下に簡単に説明する。不図示の搬送手段により、露光装置100のワークステージ105上にプリント基板等のワーク104が置かれる。ワーク104の表面(パターンを形成する側)には、レジストが塗布されている。ワークステージ105の真空吸着孔(真空吸着溝)1051に真空が供給され、ワーク104はワークステージ105上に吸着保持される。ワークステージ105への真空の供給は、露光処理中、ワーク104が移動しないように続けられる。露光処理が終わると、制御部108によって電磁弁107を切り替え、真空吸着孔(真空吸着溝)1051への真空の供給を止めてワーク104の吸着保持を解除し、真空吸着孔(真空吸着溝)1051にエアーを供給し、真空吸着孔(真空吸着溝)1051からはエアーを吹き出させる。これにより、ワーク104はワークステージ105から外れ、不図示の搬送手段により、露光装置100外に搬送される。   The operation of this exposure apparatus will be briefly described below. A workpiece 104 such as a printed circuit board is placed on the workpiece stage 105 of the exposure apparatus 100 by a conveyance unit (not shown). A resist is applied to the surface of the workpiece 104 (pattern forming side). A vacuum is supplied to the vacuum suction hole (vacuum suction groove) 1051 of the work stage 105, and the work 104 is sucked and held on the work stage 105. The supply of vacuum to the work stage 105 is continued so that the work 104 does not move during the exposure process. When the exposure process is completed, the control unit 108 switches the electromagnetic valve 107, stops supplying the vacuum to the vacuum suction hole (vacuum suction groove) 1051, releases the suction holding of the work 104, and vacuum suction hole (vacuum suction groove). Air is supplied to 1051, and air is blown out from the vacuum suction hole (vacuum suction groove) 1051. As a result, the workpiece 104 is detached from the workpiece stage 105, and is conveyed outside the exposure apparatus 100 by a conveying means (not shown).

一般に、露光等の処理を行うワークには、ウエハやガラス基板、やや厚いプリント基板、薄くて柔らかいフイルム状基板等様々な種類がある。また、例えば、CVD工程やエッチング工程を繰り返すうちに反りや変形を生じるものもある。最近は用途によっては、ガラス基板の上にシリコンウエハを貼り付けたり、サファイヤ基板上に窒化ガリウムを貼り付けたりした特殊な基板も使用されるようになってきている。このように、材質の異なる2枚の基板を貼り合わせたワークは、各材質の熱膨張係数の違いから反りが発生しやすい。ワークステージは、上記のような様々な材質や変形しているワークを吸着保持するために、真空吸着溝(孔)の形状や真空吸着方法が、種々提案されている。以下その一例について説明する。   In general, there are various types of workpieces for processing such as exposure, such as a wafer, a glass substrate, a slightly thick printed substrate, and a thin and soft film substrate. Further, for example, there are some that warp or deform while repeating a CVD process or an etching process. Recently, a special substrate in which a silicon wafer is attached on a glass substrate or gallium nitride is attached on a sapphire substrate has been used depending on applications. In this way, a workpiece in which two substrates of different materials are bonded together is likely to warp due to the difference in thermal expansion coefficient of each material. Various types of vacuum suction grooves (holes) and vacuum suction methods have been proposed for the work stage in order to suck and hold various materials as described above and deformed workpieces. One example will be described below.

特許文献1に記載されたステージ装置は、真空を供給する孔と、その孔から放射状に延びる複数の真空吸着溝を備えており、このように構成することにより、薄くて軟らかいフレキシブルな基板を、空気だまりを発生させずに吸着保持することができるものである。
また、特許文献2に記載されたワークテーブルは、ワークを吸着保持する多孔質プレートを、周縁部空気室に連通する周縁部領域と、中央部空気室に連通する中央部領域とに区分しており、例えば、周縁部領域から中央部領域へ順番に真空を供給することにより、反りが生じた薄手のワークを吸着保持することができるものである。
The stage apparatus described in Patent Document 1 includes a hole for supplying a vacuum and a plurality of vacuum suction grooves extending radially from the hole. By configuring in this way, a thin and soft flexible substrate can be obtained. It can be adsorbed and held without generating air pockets.
Further, the work table described in Patent Document 2 divides the porous plate that adsorbs and holds the work into a peripheral region that communicates with the peripheral air chamber and a central region that communicates with the central air chamber. For example, by supplying a vacuum in order from the peripheral area to the central area, a thin work having warpage can be sucked and held.

本件発明者等は、反りが生じたウエハを、反りを矯正して全面で吸着保持できるワークステージについて鋭意検討した。反りを生じたウエハは、例えば、図9(a)に示すように、椀形に反っており、φ120mmのウエハ201において、周辺部2011は中央部2012に対して1mmまたはそれ以上反っている。また、ウエハによっては、図9(b)に示すように、周辺部2021が波状に変形しているものもある。このような反りが生じているウエハ202を吸着保持するために、例えば、特許文献1や特許文献2に記載されているようなワークステージ用いて実験したが、全面を吸着保持することはできなかった。なお、これらの図では、分かり易いように、ワーク反り量は誇張して示されている。以下に、全面吸着が困難である理由について説明する。   The inventors of the present invention diligently studied a work stage that can correct and warp a warped wafer over the entire surface. For example, as shown in FIG. 9A, the warped wafer is warped in a bowl shape. In the wafer 201 having a diameter of 120 mm, the peripheral portion 2011 is warped by 1 mm or more with respect to the central portion 2012. Also, depending on the wafer, as shown in FIG. 9B, the peripheral portion 2021 may be deformed in a wave shape. In order to suck and hold the wafer 202 with such warpage, for example, an experiment was performed using a work stage as described in Patent Document 1 or Patent Document 2, but the entire surface cannot be sucked and held. It was. In these drawings, the amount of workpiece warpage is exaggerated for easy understanding. The reason why the entire surface adsorption is difficult will be described below.

従来技術に係る図10(a)のワークステージ301の断面図に示すように、放射状に延びる複数の真空吸着溝3011を備えたワークステージ301を用いた場合は、真空吸着溝3011に真空を供給しても、空気がウエハ302の反っている周辺部3021から真空吸着溝3011に向かって流れ込み、真空吸着溝3011の真空吸着圧が低下し、ウエハ302を吸着することができなかった。   As shown in the sectional view of the work stage 301 in FIG. 10A according to the prior art, when a work stage 301 having a plurality of radially extending vacuum suction grooves 3011 is used, a vacuum is supplied to the vacuum suction grooves 3011. Even so, air flows from the peripheral portion 3021 where the wafer 302 is warped toward the vacuum suction groove 3011, the vacuum suction pressure of the vacuum suction groove 3011 is lowered, and the wafer 302 cannot be sucked.

また、従来技術に係る図10(b)のワークステージ303の断面図に示すように、表面に多数の真空吸着孔3031を備えたワークステージ303を用いた場合は、ウエハ304の中央部3041は、接しているワークステージ303の中央部の真空吸着孔3031には吸着されるが、やはり、空気がウエハ304の反っている周辺部3042から真空吸着孔3031に流れ込むので、それ以上は真空吸着圧が低下し、ウエハ304全面を吸着保持することができなかった。   Further, as shown in the cross-sectional view of the work stage 303 in FIG. 10B according to the prior art, when the work stage 303 having a large number of vacuum suction holes 3031 on the surface is used, the central portion 3041 of the wafer 304 is However, since air flows into the vacuum suction hole 3031 from the peripheral part 3042 of the wafer 304 which is warped, the vacuum suction pressure is more than that. As a result, the entire surface of the wafer 304 could not be sucked and held.

また、従来技術に係る図11(a)、(b)のワークステージの断面図及び平面図に示すように、リング状の真空吸着溝を、ワークステージ401の中央部から第1の真空吸着溝4011、第2の真空吸着溝4012、第3の真空吸着溝4013・・・を複数形成し、内側の真空吸着溝から順番に、第1の真空吸着溝4011、第2の真空吸着溝4012、第3の真空吸着溝4013・・・に真空を供給するようにした。しかし、同図に示すように、ウエハ402のワークステージ401に近い部分4021が吸着され、そこから外側に向かって吸着されていく傾向にはあるものの、吸着されている部分の反対側が逆にワークステージ401から離れてしまい、そこからリークして真空吸着圧が低下し、やはりウエハ402全面を吸着保持をすることができなかった。   Further, as shown in the sectional views and plan views of the work stage of FIGS. 11A and 11B according to the prior art, the ring-shaped vacuum suction groove is formed from the center of the work stage 401 to the first vacuum suction groove. 4011, a second vacuum suction groove 4012, a third vacuum suction groove 4013..., And in order from the inner vacuum suction groove, the first vacuum suction groove 4011, the second vacuum suction groove 4012, A vacuum is supplied to the third vacuum suction grooves 4013. However, as shown in the figure, although the portion 4021 of the wafer 402 close to the work stage 401 tends to be attracted and then attracted toward the outside, the opposite side of the attracted portion is reversed to the workpiece. The wafer was separated from the stage 401, leaked from the stage 401, and the vacuum suction pressure decreased, and the entire surface of the wafer 402 could not be sucked and held.

本発明の目的は、上記の従来技術の問題点に鑑みて、真空吸着により基板(ワーク)を吸着保持するワークステージにおいて、椀形の反りが生じている基板(ワーク)であっても、その反りを矯正して基板(ワーク)全面を吸着保持することのできるワークステージ及び該ワークステージを用いた露光装置を提供することにある。   The object of the present invention is to solve the above-mentioned problems of the prior art, even in the case of a substrate (work) having a bowl-shaped warp in a work stage that holds the substrate (work) by vacuum suction. An object of the present invention is to provide a work stage capable of correcting and warping the entire surface of a substrate (work) and an exposure apparatus using the work stage.

本発明は、上記の課題を解決するために、次のような手段を採用した。
第1の手段は、真空吸着によりワークを吸着保持するワークステージにおいて、ワークを吸着保持するワークステージの表面に、第1の配管に接続された複数の真空吸着孔からなる真空吸着孔列を放射状に複数列配置した第1の真空吸着孔群と、上記第1の真空吸着孔群に挟まれる領域に形成され、第2の配管に接続された第2の真空吸着孔群と、上記ワークを吸着保持する際に、上記第1の配管から上記第1の真空吸着孔群に真空を供給し、次に、上記第2の配管から上記第2の真空吸着孔群に真空を供給する制御部と、を備えたことを特徴とするワークステージである。
第2の手段は、光を出射する光出射部と、パターンが形成されたマスクを保持するマスクステージと、上記マスクに形成されたパターンが転写されるワークを保持するワークステージとを備える露光装置において、上記ワークステージは、前記第1の手段に記載のワークステージであることを特徴とする露光装置である。

An embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a sectional view showing a schematic configuration of an exposure apparatus provided with a work stage according to the invention of this embodiment. In the following description, the work stage used in the exposure apparatus is described as an example. However, any apparatus other than the exposure apparatus can be used as long as it is an apparatus that holds and processes a work (substrate). Work stage can be applied.
As shown in FIG. 1, the exposure apparatus 1 includes a light irradiation unit 2 that emits ultraviolet rays, a mask 3 on which a pattern is formed, a mask stage 4 that holds the mask 3, a wafer on which a resist is applied, a printed board, and the like. The workpiece stage 6 that holds the workpiece 5, the projection lens 7 that projects the pattern image of the mask 3 onto the workpiece 5 held on the workpiece stage 6, and the like. Some exposure apparatuses 1 do not include the projection lens 7. The light irradiation unit 2 includes a lamp 21 that emits light including ultraviolet rays, and a mirror 22 that reflects light from the lamp 21. Further, vacuum suction hole groups 61 and 62 are formed on the surface of the work stage 6.

ワークステージ6には第1の真空配管71及び第2の真空配管72が接続され、制御部9から第1の電磁弁81及び第2の電磁弁82を制御することによって第1の真空配管71及び第2の真空配管72を介して、真空吸着孔に、ワーク5を保持する際には真空が、またワーク5をワークステージ6から取外す際にはエアーが供給される。ワークステージ6への真空の供給機構について詳述すると、第1の真空配管71には第1の電磁弁81が、第2の真空配管72には第2の電磁弁82が取り付けられている。第1の電磁弁81と第2の電磁弁82は、それぞれ制御部9に接続されており、制御部9からの動作信号により動作する。第1の真空配管71と第2の真空配管72には独立して真空が供給されるように構成されており、第1の電磁弁81が動作すると第1の真空配管71に真空が供給され、第2の電磁弁82が動作すると第2の真空配管72に真空が供給される。   A first vacuum pipe 71 and a second vacuum pipe 72 are connected to the work stage 6, and the first vacuum pipe 71 is controlled by controlling the first electromagnetic valve 81 and the second electromagnetic valve 82 from the controller 9. The vacuum suction hole is supplied with a vacuum when the work 5 is held, and when the work 5 is removed from the work stage 6, air is supplied via the second vacuum pipe 72. The mechanism for supplying vacuum to the work stage 6 will be described in detail. The first electromagnetic valve 81 is attached to the first vacuum pipe 71, and the second electromagnetic valve 82 is attached to the second vacuum pipe 72. The first electromagnetic valve 81 and the second electromagnetic valve 82 are each connected to the control unit 9 and operate according to an operation signal from the control unit 9.

As shown in FIG. 2, the work stage 6 includes a first vacuum suction hole group 61 and a second vacuum suction hole group 62. The first vacuum suction hole group 61 is formed by arranging a plurality of vacuum suction hole rows in which a plurality of vacuum suction holes X are arranged from the central portion toward the peripheral portion (outside) of the work stage 6 in a radial manner ( Indicated in the figure by X). In the figure, the first vacuum suction hole groups 61 are arranged in a straight line, but may be meandering (curved) or arranged in a zigzag form within a certain range. The second vacuum suction hole group 62 is formed in a region sandwiched between the first vacuum suction hole group 61 (indicated by Y in the figure). In the present embodiment, the diameter of each vacuum suction hole is φ1 mm, and the number thereof is 10 vacuum suction holes X of the first vacuum suction hole group 61 and vacuum suction holes of the second vacuum suction hole group 62. Y is 19. All the vacuum suction holes X of the first vacuum suction hole group 61 are connected to the first vacuum pipe 71, and all the vacuum suction holes Y of the second vacuum suction hole group 62 are connected to the second vacuum pipe 72. Is done. The vacuum for workpiece adsorption is supplied to the first vacuum pipe 71 and the second vacuum pipe 72 independently.

図4、図5、及び図6を使用して、本発明のワークステージの動作について説明する。図4(a)〜図4(c)は図3(a)の場合に相当し、図5(a)〜図5(c)は図3(b)の場合に相当する。なお、これらの図では、分かり易いように、ワーク反り量は誇張して示されている。また、図6はワークステージ6を上から見た図であり、ワーク5が吸着されていく様子を模式的に示したものである。   The operation of the work stage according to the present invention will be described with reference to FIGS. 4, 5, and 6. 4 (a) to 4 (c) correspond to the case of FIG. 3 (a), and FIGS. 5 (a) to 5 (c) correspond to the case of FIG. 3 (b). In these drawings, the amount of workpiece warpage is exaggerated for easy understanding. FIG. 6 is a view of the work stage 6 as viewed from above, and schematically shows a state in which the work 5 is attracted.

まず、図4(a)に示すように、ワークステージ6に、反りが発生しているワーク(ウエハ等)5が、不図示の搬送機構により搬送され、載置される。図1に示した制御部9が第1の電磁弁81を動作させ、第1の真空配管71にワーク吸着用の真空を供給する。第1の真空吸着孔群71の真空吸着孔Xに真空が供給される。ワーク5は椀形に反っており、その中央部かその周辺でワークステージ6と接している。そのため、ワーク5はワークステージ6の中央に設けた第1の真空吸着孔群61の真空吸着孔Xにより吸着される。   First, as shown in FIG. 4A, a workpiece (wafer or the like) 5 in which a warp is generated is transferred to and placed on the workpiece stage 6 by a transfer mechanism (not shown). The control unit 9 shown in FIG. 1 operates the first electromagnetic valve 81 to supply a vacuum for workpiece adsorption to the first vacuum pipe 71. A vacuum is supplied to the vacuum suction holes X of the first vacuum suction hole group 71. The work 5 is warped in a bowl shape and is in contact with the work stage 6 at the center or the periphery thereof. Therefore, the work 5 is sucked by the vacuum suction hole X of the first vacuum suction hole group 61 provided in the center of the work stage 6.

次に、図4(b)に示すように、第1の真空吸着孔群61は、放射状に3列形成されているので、反っているワーク5は、その3列の中でワーク5とワークステージ6との間隔が最も狭い列のワークステージ6の中央部(内側)の真空吸着孔Xに引かれて吸着される。すると、今度は、その列の外側にある真空吸着孔Xとワーク5との間隔が狭くなり、その真空吸着孔Xに引かれて吸着される(図6の矢印(1)に対応)。他の列の真空吸着孔Xは、この段階では、ワーク5を吸着できず、リークを生じている。しかし、ワークステージ6に形成されている真空吸着孔X(Y)は径がφ1mmと小さく、また真空吸着孔X(Y)の個数も少ないので、第1の真空配管71に供給する真空の圧力が上がってしまう(大気圧に近づいてしまう)ほどの大量の空気は流れ込まない。   Next, as shown in FIG. 4B, since the first vacuum suction hole group 61 is formed in three rows in a radial pattern, the warped workpiece 5 is the workpiece 5 and the workpiece in the three rows. It is attracted to the vacuum suction hole X in the central portion (inner side) of the work stages 6 in the row having the narrowest distance from the stage 6. Then, this time, the space between the vacuum suction hole X outside the row and the work 5 is narrowed, and the vacuum suction hole X is pulled and sucked (corresponding to the arrow (1) in FIG. 6). The vacuum suction holes X in the other rows cannot leak the workpiece 5 at this stage, causing a leak. However, since the vacuum suction hole X (Y) formed in the work stage 6 has a small diameter of φ1 mm and the number of vacuum suction holes X (Y) is small, the pressure of the vacuum supplied to the first vacuum pipe 71 is reduced. A large amount of air will not flow in so as to rise (approaching atmospheric pressure).

やがて、図4(c)に示すように、反ったワーク5は、第1の真空吸着孔群71の1列により吸着される(図6の矢印(1)に対応)。この状態を、図2のB−B断面図で見ると、図5(a)に示すようになる。   Eventually, as shown in FIG. 4C, the warped work 5 is sucked by one row of the first vacuum suction hole group 71 (corresponding to the arrow (1) in FIG. 6). When this state is seen in the BB sectional view of FIG. 2, it becomes as shown in FIG.

次に、図5(a)に示す状態で、制御部9は第2の電磁弁82を動作させ、第2の真空配管72にワーク吸着用の真空を供給すると、第2の真空吸着孔群62に真空が供給される。第2の真空配管72に真空を供給するタイミングは、第1の真空配管71に真空を供給してから第2の真空配管72に真空を供給するまでの時間(数秒から数十秒)であり、タイマーで設定しても良いし、ワーク5が第1の真空吸着孔群61の1列に吸着されると、第1の真空配管71に供給する真空の圧力が変動する(圧力が多少下がる)ので、その変動を真空センサにより検出し、第2の真空配管72に供給するようにしてもよい。   Next, in the state shown in FIG. 5A, when the control unit 9 operates the second electromagnetic valve 82 and supplies a vacuum for workpiece suction to the second vacuum pipe 72, the second vacuum suction hole group. A vacuum is supplied to 62. The timing for supplying the vacuum to the second vacuum pipe 72 is the time from supplying the vacuum to the first vacuum pipe 71 to supplying the vacuum to the second vacuum pipe 72 (several seconds to several tens of seconds). The pressure may be set by a timer, or when the work 5 is sucked into one row of the first vacuum suction hole group 61, the pressure of the vacuum supplied to the first vacuum pipe 71 fluctuates (the pressure slightly decreases). Therefore, the fluctuation may be detected by a vacuum sensor and supplied to the second vacuum pipe 72.

次に、図5(b)に示すように、ワーク5は、第1の真空吸着孔群61の1列により吸着されているので、ワーク5を吸着している真空吸着孔Xの列の隣にある、第2の真空吸着孔群62の真空吸着孔Yとワーク5の間隔は狭くなっている。そのため、ワーク5はこの第2の真空吸着孔群62の真空吸着孔Yに引かれて吸着される(図6の矢印(2)に対応)。ワーク5が、第1の真空吸着孔群61の隣にある第2の真空吸着孔群62の真空吸着孔Yに吸着されると、第2の真空吸着孔群62において、さらにその周方向に隣りの真空吸着孔Yや径方向(外側)の隣りの真空吸着孔Yにワーク5は吸着されていく(図6の矢印(3)に対応)。   Next, as shown in FIG. 5B, since the workpieces 5 are adsorbed by one row of the first vacuum suction hole group 61, next to the row of the vacuum suction holes X that suck the workpieces 5. The distance between the vacuum suction hole Y of the second vacuum suction hole group 62 and the work 5 is narrow. Therefore, the work 5 is attracted by being attracted by the vacuum suction hole Y of the second vacuum suction hole group 62 (corresponding to the arrow (2) in FIG. 6). When the work 5 is adsorbed by the vacuum suction hole Y of the second vacuum suction hole group 62 adjacent to the first vacuum suction hole group 61, the workpiece 5 is further moved in the circumferential direction in the second vacuum suction hole group 62. The workpiece 5 is sucked into the adjacent vacuum suction hole Y or the adjacent vacuum suction hole Y in the radial direction (outside) (corresponding to the arrow (3) in FIG. 6).

図5(c)に示すように、ワーク5は、反りが矯正されながら順次周方向に吸着され、最初はワーク5が吸着されていなかった第1の真空吸着孔群61の真空吸着孔列にまで達する。すると、現段階では、ワーク5は第2の真空吸着孔群62により吸着されているので、ワーク5と第1の真空吸着孔群61の真空吸着孔列との間隔は狭くなっており、ワーク5は第1の真空吸着孔群61の真空吸着孔列により吸着される(図6の矢印(4)に対応)。ワーク5が第1の真空吸着孔群61の真空吸着孔列Xに吸着されると、ワーク5はさらにその隣りにある第2の真空吸着孔群62の真空吸着孔Yによりワークステージ6の周方向と径方向に順次吸着されていく(図6の矢印(5)に対応)。そして、最後に、ワーク5は反りが矯正されてワークステージ6全面で吸着保持される(図6の矢印(7)に対応)。   As shown in FIG. 5C, the workpieces 5 are sequentially sucked in the circumferential direction while warping is corrected, and the workpieces 5 are first placed in the vacuum suction hole rows of the first vacuum suction hole group 61 in which the workpieces 5 are not sucked. Reach up to. Then, at the present stage, since the work 5 is sucked by the second vacuum suction hole group 62, the interval between the work 5 and the vacuum suction hole row of the first vacuum suction hole group 61 is narrowed. 5 is adsorbed by the vacuum suction hole array of the first vacuum suction hole group 61 (corresponding to the arrow (4) in FIG. 6). When the work 5 is sucked by the vacuum suction hole row X of the first vacuum suction hole group 61, the work 5 is further surrounded by the vacuum suction hole Y of the second vacuum suction hole group 62 adjacent thereto. Adsorbed sequentially in the direction and the radial direction (corresponding to the arrow (5) in FIG. 6). Finally, the work 5 is warped and is held by suction on the entire surface of the work stage 6 (corresponding to the arrow (7) in FIG. 6).

本件発明者等は、本実施形態の発明に係るワークステージを用いて、実際に、ワークとして、周辺部が中央部に対して1mm程度反るとともに周辺部が波状に変形している10枚のφ120mmのウエハを使用したところ、10枚全てのウエハが、ワークステージにより全面で吸着保持できることを確認した。   The inventors of the present invention, using the work stage according to the invention of the present embodiment, actually, as the work, the peripheral portion is warped about 1 mm with respect to the central portion, and the peripheral portion is deformed in a wavy shape When a φ120 mm wafer was used, it was confirmed that all 10 wafers could be sucked and held on the entire surface by the work stage.

図7は、第2の実施形態の発明に係るワークステージの構成を示す平面図である。
同図に示すように、このワークステージ6は、第1の実施形態のワークステージ6においては第1の真空吸着孔群61が放射状に3列形成されていたのに対して、放射状に4列形成した点で相違する。本実施形態のワークステージ6においても、第1の実施形態のワークステージ6と同様に機能させることができる。
FIG. 7 is a plan view showing the configuration of the work stage according to the invention of the second embodiment.
As shown in the figure, this work stage 6 has four rows in the radial direction, whereas the first vacuum suction hole group 61 is formed in three rows in the work stage 6 of the first embodiment. It differs in the point formed. The work stage 6 of the present embodiment can also function in the same manner as the work stage 6 of the first embodiment.

上記の各実施形態の発明に係るワークステージの要点をまとめると以下のとおりである。第1に、ワークステージ6の表面に形成する真空吸着手段61、62は、溝ではなく孔にする。このことにより、リークによる真空吸着圧力の低下を防ぐことができる。第2に、放射状に形成する第1の真空吸着孔群61の真空吸着孔Xの周方向の隣に形成する真空吸着孔は、第2の真空吸着孔群62の真空吸着孔Yとする。なお、第2の真空吸着孔群62の真空吸着孔Yの周方向隣には、第2の真空吸着孔群62の真空吸着孔Yがあっても良い。このことにより、椀形に反ったワーク5を、まず1ケ所(または1列)径方向に吸着し、次に周方向に吸着していく。したがって、ワーク5は徐々に反りが矯正され、ワークステージ6全面に吸着される。   The main points of the work stage according to the invention of each of the above embodiments are summarized as follows. First, the vacuum suction means 61 and 62 formed on the surface of the work stage 6 are holes instead of grooves. This can prevent a decrease in the vacuum adsorption pressure due to leakage. Secondly, the vacuum suction hole formed next to the circumferential direction of the vacuum suction hole X of the first vacuum suction hole group 61 formed radially is the vacuum suction hole Y of the second vacuum suction hole group 62. In addition, the vacuum suction hole Y of the second vacuum suction hole group 62 may be adjacent to the second vacuum suction hole group 62 in the circumferential direction of the vacuum suction hole Y. As a result, the workpiece 5 warped in a bowl shape is first sucked in one (or one row) radial direction and then sucked in the circumferential direction. Accordingly, the workpiece 5 is gradually warped and is attracted to the entire surface of the workpiece stage 6.
