Description

本発明は、被処理基板を平流し方式で水平方向に搬送する基板搬送装置に関し、特に被処理基板としてFPD(フラットパネルディスプレイ)等に用いる被処理基板を搬送する基板搬送装置に関する。   The present invention relates to a substrate transport apparatus that transports a substrate to be processed in a horizontal direction by a flat flow method, and more particularly to a substrate transport apparatus that transports a substrate to be processed used in an FPD (flat panel display) or the like as a substrate to be processed.

近年、FPD製造におけるレジスト塗布現像処理システムでは、FPD用基板(たとえばガラス基板)の大型化に有利に対応できる現像方式として、コロを水平方向に敷設した搬送路上で基板を搬送しながら現像、リンス、乾燥等の一連の現像処理工程を行うようにした、いわゆる平流し方式が普及している。このような平流し方式は、基板を回転運動させるスピンナ方式と較べて、大型基板の取扱いが簡単であり、ミストの発生ないし基板への再付着が少ない等の利点がある。   In recent years, in resist coating and developing processing systems in FPD manufacturing, development and rinsing are carried out while transporting a substrate on a transport path in which rollers are laid in a horizontal direction as a development method that can advantageously cope with an increase in size of an FPD substrate (for example, a glass substrate) A so-called flat-flow method in which a series of development processing steps such as drying is performed has become widespread. Such a flat flow method has advantages such as easier handling of a large substrate and less occurrence of mist or reattachment to the substrate, compared to a spinner method that rotates the substrate.

前記平流しの搬送方式においては、従来、例えば図9の平面図に示すように丸棒状の搬送コロ201を搬送方向に一定間隔で敷設してなる。各コロ201は、それぞれ一定の太さ(径)を有する剛体(例えばSUS製)のシャフトを有している。各コロ201の両端は、フレーム203に固定された左右一対の軸受204に水平姿勢で回転可能に支持されている。
各コロ201をそれぞれ駆動するための搬送駆動部は、駆動源の電気モータ202と、この電気モータ202の回転駆動力を各コロ201に伝えるための伝動機構とを有する。この伝動機構は、電気モータ202の回転軸に無端ベルト205を介して接続された搬送方向に延びる回転駆動シャフト206と、各コロ201とを作動結合する交差軸型のギア207とで構成されている。
In the above-described flat-flow conveying method, conventionally, for example, as shown in the plan view of FIG. 9, round bar-shaped conveying rollers 201 are laid at regular intervals in the conveying direction. Each roller 201 has a rigid (for example, SUS) shaft having a certain thickness (diameter). Both ends of each roller 201 are rotatably supported in a horizontal posture by a pair of left and right bearings 204 fixed to the frame 203.
The conveyance driving unit for driving each roller 201 includes an electric motor 202 as a driving source and a transmission mechanism for transmitting the rotational driving force of the electric motor 202 to each roller 201. This transmission mechanism is composed of a rotary drive shaft 206 connected to the rotary shaft of the electric motor 202 via an endless belt 205 and extending in the transport direction, and a cross shaft type gear 207 that operatively couples each roller 201. Yes.

この構成において、電気モータ202が駆動すると、前記伝動機構により各コロ201が一方向に回転し、コロ201上の基板Gが搬送されるようになされている。
しかしながら、そのように複数の搬送コロ201を敷設した構成の場合、搬送される基板Gの下面が複数の搬送コロ201によって隠れるため、基板Gを搬送しながら、その下面に対し所定の処理(例えば洗浄、熱処理等)を施すことができず、処理効率が低下するという課題があった。また、使用する搬送コロ201の本数が多いために、コストが嵩むという課題があった。
In this configuration, when the electric motor 202 is driven, each roller 201 is rotated in one direction by the transmission mechanism, and the substrate G on the roller 201 is conveyed.
However, in the case of a configuration in which a plurality of transfer rollers 201 are laid in this manner, the lower surface of the substrate G to be transferred is hidden by the plurality of transfer rollers 201, so that a predetermined treatment (for example, Cleaning, heat treatment, etc.) could not be performed, and there was a problem that processing efficiency decreased. Moreover, since the number of the conveyance rollers 201 to be used is large, there is a problem that the cost increases.

前記課題を解決するものとして、本願出願人が特許文献1に開示した加熱モジュールの基板搬送構造がある。図10に、特許文献1に開示された加熱モジュールの構成を斜視図により示す。図10に示す加熱モジュール250においては、被処理基板であるウエハWを平流し搬送するための搬送路部251を備える。   As a solution to the above-described problem, there is a substrate transport structure for a heating module disclosed in Patent Document 1 by the present applicant. In FIG. 10, the structure of the heating module disclosed by patent document 1 is shown with a perspective view. The heating module 250 shown in FIG. 10 includes a transport path 251 for transporting the wafer W, which is a substrate to be processed, in a flat flow.

前記搬送路部251は、水平軸周りに回動し、回動軸が互いに平行となるように前後に配置された一対のプーリ252、253を有し、これら相対向するプーリ252、253の間には、一対のタイミングベルト254、255が掛け回されている。前記一対のタイミングベルト254、255の間には、多数のワイヤ256が並列に設けられている。
前記プーリ252は、モータ257により回転駆動され、それに掛け回されたタイミングベルト254、255が周回軌道に沿って移動し、ワイヤ256上に載置されたウエハWが搬送される構成となされている。
The conveyance path portion 251 has a pair of pulleys 252 and 253 that are rotated around a horizontal axis and arranged in front and back so that the rotation axes are parallel to each other, and between the pulleys 252 and 253 facing each other. A pair of timing belts 254 and 255 are wound around. A large number of wires 256 are provided in parallel between the pair of timing belts 254 and 255.
The pulley 252 is rotationally driven by a motor 257, and the timing belts 254 and 255 wound around the pulley 252 move along a circular path so that the wafer W placed on the wire 256 is conveyed. .

この加熱モジュール250にあっては、平流し搬送しながら加熱処理を行うモジュールであるため、搬送路部251における搬送経路に沿って、ウエハWを冷却する第一の冷却プレート258、ウエハWを加熱する熱板259、熱板259によって加熱されたウエハWを冷却する第二の冷却プレート260が順に設けられている。
したがって、被処理基板でありウエハWを搬送しながら、その下面に対しても熱処理を施すことができ、ウエハWに対する処理を効率的に行うことができる。
Since the heating module 250 is a module that performs heat treatment while carrying a flat flow, the first cooling plate 258 for cooling the wafer W and the wafer W are heated along the transfer path in the transfer path section 251. A hot plate 259 that is heated, and a second cooling plate 260 that cools the wafer W heated by the hot plate 259 are sequentially provided.
Accordingly, while the wafer W, which is the substrate to be processed, is transported, the lower surface thereof can be heat treated, and the wafer W can be processed efficiently.

しかしながら、特許文献1に開示された加熱モジュール250の搬送路部251にあっては、基板処理後の被処理基板を基板搬送アーム(図示せず)に受け渡す際に、タイミングベルト254、255の駆動を一旦停止する必要があり、効率が悪かった。
即ち、被処理基板の搬入出のために搬送路部251の搬送駆動を停止すると、搬送路上にある他の被処理基板に対する処理に影響が生じるため、加熱モジュール250に連続的に被処理基板を投入することができず、スループット向上が望めないという課題があった。
However, in the transport path portion 251 of the heating module 250 disclosed in Patent Document 1, when the substrate to be processed after the substrate processing is transferred to a substrate transport arm (not shown), the timing belts 254 and 255 The drive had to be stopped once, and the efficiency was poor.
That is, if the conveyance drive of the conveyance path unit 251 is stopped for loading and unloading the substrate to be processed, the processing on other substrates to be processed on the conveyance path is affected. There was a problem that it could not be put in and throughput improvement could not be expected.

図1に示すように2本の回転軸2,3の間で基板搬送方向(X軸方向)に相対向するタイミングプーリ4、5間には、タイミングベルト6、7(第一無端駆動部材)が掛け回されている。即ち、基板搬送路の左右両側において、タイミングベルト6,7は、タイミングプーリ4,5の回転によって周回軌道に沿って移動するように設けられている。尚、タイミングプーリ4,5の回転方向は、タイミングベルト6,7の上面部が基板搬送方向に移動する方向となされている。
また、基板搬送方向に沿って平行に設けられた前記一対のタイミングベルト6,7間には、線状部材である多数のロッド部材8がY軸方向に並列に架設されている。尚、このロッド部材8は、弾性を有する部材、例えばカーボンファイバーにより形成され、その直径は例えば10mmとなされている。
基板Gは、搬送方向に移動する前記タイミングベルト6,7及びロッド部材8上で搬送されるが、タイミングベルト6、7上に基板Gの左右両側縁部が載置され、基板Gの中央部は前記ロッド部材8によって支持されるようになされている。
As shown in FIG. 1, the timing belts 6 and 7 (first endless driving member) are disposed between the timing pulleys 4 and 5 facing each other in the substrate transport direction (X-axis direction) between the two rotating shafts 2 and 3. Is hung around. In other words, the timing belts 6 and 7 are provided on both the left and right sides of the substrate transport path so as to move along the circular path by the rotation of the timing pulleys 4 and 5. Note that the rotation direction of the timing pulleys 4 and 5 is the direction in which the upper surface portions of the timing belts 6 and 7 move in the substrate transport direction.
Further, between the pair of timing belts 6 and 7 provided in parallel along the substrate transport direction, a large number of rod members 8 which are linear members are laid in parallel in the Y-axis direction. The rod member 8 is formed of an elastic member, such as carbon fiber, and has a diameter of, for example, 10 mm.
The substrate G is transported on the timing belts 6 and 7 and the rod member 8 that move in the transport direction. The left and right side edges of the substrate G are placed on the timing belts 6 and 7, and the central portion of the substrate G is placed. Is supported by the rod member 8.

また、タイミングプーリ4,5の間に張架されたタイミングベルト6,7(基板Gを支持する部分の裏側)には、図1に示すように複数のアイドラプーリ12(支持滑車)が回転自在に設けられ、下方に撓むことのないようになされている。
また、一方の回転軸3は駆動軸となるため、図2、図3に示すようにカップリング13を介して駆動部であるモータ14が連結されている。即ち、モータ14により回転軸3が回転駆動され、タイミングプーリ5が回転することによってタイミングベルト6,7が一方向に周回移動するようになされている。
Further, a plurality of idler pulleys 12 (support pulleys) are freely rotatable on the timing belts 6 and 7 (back side of the portion supporting the substrate G) stretched between the timing pulleys 4 and 5 as shown in FIG. It is made so as not to bend downward.
Moreover, since one rotating shaft 3 becomes a drive shaft, as shown in FIG. 2, FIG. 3, the motor 14 which is a drive part is connected via the coupling 13. As shown in FIG. In other words, the rotation shaft 3 is driven to rotate by the motor 14, and the timing pulley 5 rotates so that the timing belts 6 and 7 move in one direction.

また、この基板搬送装置1にあっては、タイミングベルト上に基板Gの側縁部が載置されると共に、基板Gの中央部はロッド部材8により支持されるため、従来のコロ部材のように多数敷設する必要がなく、ロッド部材8間に所定の間隔を空けて配置することができる。その結果、図4に示すように搬送される基板Gの上下方向に基板処理に必要なスペースSを確保することができる。
例えば、この基板搬送装置1を基板洗浄装置に適用する場合、図5に示すように基板Gが載置されるタイミングベルト6(7)の裏側を支持するアイドラプーリ15a(支持滑車)の間に、タイミングベルト6(7)の周回軌道を変換するアイドラプーリ15b(変換滑車)が配置される。このアイドラプーリ15bによりタイミングベルト6(7)が下方に凹状に屈曲する迂回路(区間)が形成され、基板洗浄のためのクリーニングローラ16を基板上下に対配置した構造とすることができる。
したがって、基板Gを安定して搬送しながら、その上下面に対し効率的にクリーニングローラ16によるクリーニング処理を施すことができる。
Moreover, in this board | substrate conveyance apparatus 1, since the side edge part of the board | substrate G is mounted on a timing belt and the center part of the board | substrate G is supported by the rod member 8, it is like the conventional roller member. It is not necessary to lay a large number on the rod member 8 and the rod members 8 can be arranged with a predetermined interval. As a result, as shown in FIG. 4, a space S necessary for substrate processing can be secured in the vertical direction of the substrate G being transferred.
For example, when this substrate transport apparatus 1 is applied to a substrate cleaning apparatus, as shown in FIG. 5, between idler pulleys 15a (support pulleys) that support the back side of the timing belt 6 (7) on which the substrate G is placed. An idler pulley 15b (conversion pulley) that converts the orbit of the timing belt 6 (7) is disposed. By this idler pulley 15b, a detour (section) in which the timing belt 6 (7) is bent concavely downward is formed, and a cleaning roller 16 for cleaning the substrate can be arranged in a pair above and below the substrate.
Therefore, the cleaning process by the cleaning roller 16 can be efficiently performed on the upper and lower surfaces of the substrate G while stably transporting the substrate G.

また、本発明に係る基板搬送装置1にあっては、前記のように基板Gに対し所定の処理(熱処理、洗浄処理等)を行った後に、基板Gを搬送アーム(図示せず)に受け渡すための機構を有する。具体的には、図1に示すように、この基板搬送装置1の後端部(基板搬送路の後端部)において、タイミングベルト6,7の間に配置された基板受け渡し機構20を備える。この基板受け渡し機構20について、さらに図6の平面図、及び図7の側面図を用いて説明する。   In the substrate transfer apparatus 1 according to the present invention, the substrate G is received by a transfer arm (not shown) after performing predetermined processing (heat treatment, cleaning process, etc.) on the substrate G as described above. Has a mechanism for passing. Specifically, as shown in FIG. 1, a substrate transfer mechanism 20 disposed between the timing belts 6 and 7 is provided at the rear end portion (the rear end portion of the substrate transfer path) of the substrate transfer apparatus 1. The substrate delivery mechanism 20 will be further described with reference to the plan view of FIG. 6 and the side view of FIG.

基板受け渡し機構20は、回転軸3において前記一対のタイミングプーリ5の間に設けられ、タイミングプーリ5の回転と同期して軸周りに回転する複数(図では3つ)のタイミングプーリ21(第三滑車部材)を備える。さらに、タイミングプーリ21よりも上流側において基板搬送方向に沿って各タイミングプーリ21と相対向して設けられ、回転軸3と平行な回転軸24によって回転自在に設けられた複数のタイミングプーリ22(第四滑車部材)を備える。前記回転軸24は、軸受23に軸支されている。   The substrate transfer mechanism 20 is provided between the pair of timing pulleys 5 on the rotary shaft 3 and is rotated around the shaft in synchronization with the rotation of the timing pulley 5 (three in the figure) 21 (third). A pulley member). Further, a plurality of timing pulleys 22 (provided to face each timing pulley 21 along the substrate conveyance direction on the upstream side of the timing pulley 21 and rotatably provided by a rotation shaft 24 parallel to the rotation shaft 3 ( A fourth pulley member). The rotary shaft 24 is pivotally supported by the bearing 23.

前記対配置されたタイミングプーリ21、22間には、それぞれタイミングベルト25(第二無端駆動部材)が掛け回され、タイミングプーリ21、22の回転によって、周回軌道に沿って移動するようになされている。
ここで、回転軸3に設けられたタイミングプーリ21の回転駆動は、モータ14の駆動によってなされるため、基板Gが載置されるタイミングベルト6,7の周回移動と共に、タイミングベルト25も同期して周回移動するようになされている。
尚、タイミングプーリ21、22は、タイミングプーリ4,5よりも小径であり、それに掛け回されたタイミングベルト25がロッド部材8に干渉しないようになされている。
A timing belt 25 (second endless drive member) is wound between the paired timing pulleys 21 and 22, and is moved along a circular path by the rotation of the timing pulleys 21 and 22. Yes.
Here, since the rotation of the timing pulley 21 provided on the rotating shaft 3 is driven by the motor 14, the timing belt 25 is synchronized with the circumferential movement of the timing belts 6 and 7 on which the substrate G is placed. To move around.
The timing pulleys 21 and 22 are smaller in diameter than the timing pulleys 4 and 5, and the timing belt 25 wound around the timing pulleys 21 and 22 does not interfere with the rod member 8.

また、前記複数のタイミングベルト25の表面には、図示するようにベルト表面に対し(即ち周回移動方向に対し)直交方向に延びる棒状の基板支持部材26が、基板搬送方向に沿って所定間隔毎に立設されている。
これら複数の基板支持部材26は、図7に示すように、その先端の回転部材27(回転体)上で基板Gを支持するものであり、前記回転部材27は、タイミングベルト6、7における基板搬送高さよりも突出し、所定高さ寸法h高くなるように設けられている。
前記回転部材27は、具体的には基板支持部材26の棒体26aの先端に回転自在に設けられたボールベアリング(球体)からなる。
Further, on the surfaces of the plurality of timing belts 25, rod-like substrate support members 26 extending in a direction orthogonal to the belt surfaces (that is, with respect to the circumferential movement direction) as shown in the figure are arranged at predetermined intervals along the substrate transport direction. Is erected.
As shown in FIG. 7, the plurality of substrate support members 26 support the substrate G on a rotating member 27 (rotating body) at the tip thereof, and the rotating member 27 is a substrate in the timing belts 6 and 7. It is provided so as to protrude from the conveying height and to be higher by a predetermined height dimension h.
Specifically, the rotating member 27 is composed of a ball bearing (spherical body) rotatably provided at the tip of the rod body 26a of the substrate support member 26.

タイミングベルト25に対し基板支持部材26を取り付ける構造としては、例えば図8(a)に示すように、先端に回転体27が設けられた棒体26aを、タイミングベルト25に一体形成されたボス28に(例えばエンザートを介して)ねじ込むことにより固定し、設けることができる。
あるいは、図8(b)に示すように、棒体26aのねじ切りされた先端26bを、タイミングベルト25を貫通させて、タイミングベルト25の裏側からナット29により固定してもよい。
またあるいは、図8(c)に示すようにタイミングベルト25(図では正面からの断面)を一対の板部材30、31により上下から挟み込み、螺子32により固定してもよい。この場合、ベルト表側の板部材30上に棒体26aが一体形成されていることが望ましい。
As a structure for attaching the substrate support member 26 to the timing belt 25, for example, as shown in FIG. 8A, a boss 28 integrally formed with the timing belt 25 is provided with a rod body 26 a provided with a rotating body 27 at the tip. It can be fixed and provided by screwing (for example, through an enzant).
Alternatively, as shown in FIG. 8B, the threaded tip 26 b of the rod body 26 a may be passed through the timing belt 25 and fixed with a nut 29 from the back side of the timing belt 25.
Alternatively, as shown in FIG. 8C, the timing belt 25 (in the drawing, a cross section from the front) may be sandwiched from above and below by a pair of plate members 30 and 31 and fixed by screws 32. In this case, it is desirable that the rod body 26a is integrally formed on the plate member 30 on the belt front side.

このようにタイミングベルト25に対し、基板支持部材26は搬送方向に沿って所定間隔毎に設けられており、タイミングベルト25の周回移動と共に(ベルトに対し)直立した状態で移動するようになされている。尚、タイミングベルト6,7間に架設されたロッド部材8と、タイミングベルト25上の基板支持部材26とは、それぞれが干渉しないよう配置されている。
このように構成されることにより、基板支持部材26の先端の回転体27もまた周回軌道に沿って移動し、図7に示すように、タイミングベルト6,7から基板受け渡し機構20に基板Gが受け渡される区間においては、前記基板支持部材26(先端の回転体27)によって上りエスカレータのようにタイミングベルト6,7の高さから徐々に上昇軌道となる基板搬送路が形成される。
In this way, the substrate support member 26 is provided at predetermined intervals along the conveyance direction with respect to the timing belt 25, and moves in an upright state (with respect to the belt) as the timing belt 25 rotates. Yes. The rod member 8 installed between the timing belts 6 and 7 and the substrate support member 26 on the timing belt 25 are arranged so as not to interfere with each other.
With this configuration, the rotating body 27 at the tip of the substrate support member 26 also moves along the circular path, and the substrate G is transferred from the timing belts 6 and 7 to the substrate delivery mechanism 20 as shown in FIG. In the section to be transferred, a substrate transport path that gradually rises from the height of the timing belts 6 and 7 is formed by the substrate support member 26 (rotary body 27 at the front end) like an ascending escalator.

したがって、タイミングベルト6,7によって搬送されてきた基板Gは、基板受け渡し機構20に差し掛かると、基板支持部材26によって、基板先端から徐々に上方に持ち上げられ、最終的には図7に示すように基板全体が複数の基板支持部材26の先端の回転体27によって支持される。   Accordingly, when the substrate G transported by the timing belts 6 and 7 reaches the substrate transfer mechanism 20, it is gradually lifted upward from the front end of the substrate by the substrate support member 26, and finally, as shown in FIG. The entire substrate is supported by the rotating body 27 at the tip of the plurality of substrate support members 26.

尚、タイミングベルト6,7の表面には、凸状に形成され、その側面で基板Gの後端角部を支持するガイド部35(ガイド部材)が設けられている。このため、基板Gが基板支持部材26によって上方に持ち上げられる際に、ガイド部35が基板後端部を支持し、基板Gが後方に滑らないようにして、確実に基板Gを基板受け渡し機構20上に移動させることができる。
また、前記したようにタイミングベルト6,7の裏側に設けられたアイドラプーリ12のうち、図7に示すようにタイミングベルト6,7から基板受け渡し機構20に基板Gが受け渡される区間に設けられたアイドラプーリ12aは、他より高い位置に配置されている。この配置によりアイドラプーリ12aに掛かったタイミングベルト6,7は山なりとなって、上りエスカレータ状の搬送路がより滑らかに形成され、タイミングベルト6,7に載置されていた基板Gを、基板受け渡し機構20上に移動し易くすることができる。
Note that the surface of the timing belts 6 and 7 is provided with a guide portion 35 (guide member) which is formed in a convex shape and supports the rear end corner portion of the substrate G on its side surface. For this reason, when the substrate G is lifted upward by the substrate support member 26, the guide portion 35 supports the rear end portion of the substrate, prevents the substrate G from sliding backward, and reliably transfers the substrate G to the substrate transfer mechanism 20. Can be moved up.
Further, as described above, the idler pulley 12 provided on the back side of the timing belts 6 and 7 is provided in a section where the substrate G is delivered from the timing belts 6 and 7 to the substrate delivery mechanism 20 as shown in FIG. The idler pulley 12a is arranged at a higher position than the others. With this arrangement, the timing belts 6 and 7 hung on the idler pulley 12a are crested, and the ascending escalator-like conveyance path is formed more smoothly, and the substrate G placed on the timing belts 6 and 7 is replaced with the substrate It can be easily moved on the delivery mechanism 20.

また、図7に示すように基板受け渡し機構20の下流側端部において、基板支持部材26によって支持された基板Gの先端部に当接し、基板Gの移動を停止するためのストッパ部材36(基板受け部材)が設けられている。このストッパ部材36は例えばチャンバ内壁37等に設けられている。
前記したように、基板支持部材26の先端はボールベアリング構造の回転体27であるため、基板Gの移動がストッパ部材36によって停止されても、基板支持部材26は基板Gの下面を周回軌道に沿って滑らかに移動する。また、基板Gの振動も抑制される。
したがって、タイミングベルト6,7の周回移動を停止することなく、所定の基板処理が完了した基板Gは基板受け渡し機構20の所定位置に保持され、この状態で搬送アーム(図示せず)に基板Gが受け渡される。
Further, as shown in FIG. 7, a stopper member 36 (a substrate for stopping the movement of the substrate G by contacting the tip end portion of the substrate G supported by the substrate support member 26 at the downstream end portion of the substrate delivery mechanism 20. Receiving member). The stopper member 36 is provided on the chamber inner wall 37, for example.
As described above, since the tip of the substrate support member 26 is the rotating body 27 having the ball bearing structure, even if the movement of the substrate G is stopped by the stopper member 36, the substrate support member 26 uses the lower surface of the substrate G as a circular orbit. Move along smoothly. Further, the vibration of the substrate G is also suppressed.
Accordingly, the substrate G that has been subjected to the predetermined substrate processing is held at a predetermined position of the substrate transfer mechanism 20 without stopping the circular movement of the timing belts 6 and 7, and in this state, the substrate G is held on the transfer arm (not shown). Is passed.

以上のように、本発明に係る実施の形態によれば、タイミングベルト6,7によって搬送されてきた基板Gを基板受け渡し機構20により受け取り、基板支持部材26の回転体27上で支持することにより、タイミングベルト6,7の周回移動を継続した状態で、基板受け渡し機構20上の所定位置において基板Gを保持することができる。
したがって、基板搬送装置1において、基板搬送を停止することなく搬送アームへの基板Gの受け渡しが可能となり、基板搬送装置1における他の基板処理に影響を与えないため、スループットを向上することができる。
As described above, according to the embodiment of the present invention, the substrate G transported by the timing belts 6 and 7 is received by the substrate transfer mechanism 20 and supported on the rotating body 27 of the substrate support member 26. The substrate G can be held at a predetermined position on the substrate transfer mechanism 20 in a state where the circular movement of the timing belts 6 and 7 is continued.
Therefore, in the substrate transfer apparatus 1, the substrate G can be transferred to the transfer arm without stopping the substrate transfer, and other substrate processing in the substrate transfer apparatus 1 is not affected, so that the throughput can be improved. .

尚、前記実施の形態においては、基板支持部材26の先端に設けられる回転体として、ボール部材を例に説明したが、それに限定されず、滑車形状の回転体でもよい。
また、基板支持部材26は棒体の形状に限定されるものではなく、基板Gに当接する回転体を回転自在に保持することができれば、他の形状であってもよい。
また、線状部材として、例えばカーボンファイバーからなるロッド部材8を示したが、本発明の基板搬送装置にあっては、それに限定されず、線状部材として弾性を有するワイヤ部材(SUS等により形成)を用いてもよい。
また、無端駆動部材としてタイミングベルト6,7、21を用いたが、それに限定されず、無端駆動部材としてチェーンを用いてもよい。
In the above-described embodiment, the ball member is described as an example of the rotating body provided at the tip of the substrate support member 26. However, the rotating body is not limited to this and may be a pulley-shaped rotating body.
Further, the substrate support member 26 is not limited to the shape of a rod body, and may have other shapes as long as the rotating body that contacts the substrate G can be rotatably held.
Further, the rod member 8 made of, for example, carbon fiber is shown as the linear member. However, the substrate transport apparatus of the present invention is not limited to this, and the linear member is made of an elastic wire member (SUS or the like). ) May be used.
Further, although the timing belts 6, 7, and 21 are used as the endless driving member, the present invention is not limited thereto, and a chain may be used as the endless driving member.

また、前記実施の形態においては、基板受け渡し機構を基板搬送装置1(基板搬送路)の後端部に設け、基板Gに対し所定の処理(熱処理、洗浄処理等)を行った後に、基板Gを搬送アーム(図示せず)に受け渡すものとした。
しかしながら、本発明に係る基板搬送装置においては、その構成に限定されず、基板受け渡し機構を基板搬送装置1(基板搬送路)の前端部に設け、搬送アーム(図示せず)から基板Gを受け取って所定位置に支持し、所定のタイミングでタイミングベルト6,7上に受け渡すように構成してもよい。その場合、基板支持部材26によって支持された基板Gの先端部に当接し、基板Gの移動を停止するためのストッパ部材36(基板受け部材)を基板先端に対して進退移動させ、基板Gの移動を制御することが望ましい。
また、この基板受け渡し機構は、基板搬送装置1(基板搬送路)の前端部と後端部のいずれか一方、或いは、その両方に設けられる構成であってもよい。
