Abstract

<P>PROBLEM TO BE SOLVED: To provide a substrate processing device which prevents leakage of mist-like cleaning liquid to an outside and does not cause entering of particles from the outside. <P>SOLUTION: A fan 9 which rotates integrally with a rotating shaft 4 is fixed to the rotating shaft 4, and air flow in an area near a through hole 5a outside a cover 5 is generated in a direction perpendicular to an extension direction of the rotating shaft 4 in a direction toward a circumferential direction of the rotating shaft 4. Consequently, the mist-like cleaning liquid existing in an area near the through hole 5a outside the cover 5 is guided along the inner wall of a casing 6, and the mist-like cleaning liquid is prevented from leaking outside from the through hole 6a of the casing 6. Furthermore, air which is about to enter from an outside toward the through hole 5a of the cover 5 is also guided toward the circumferential direction of the rotating shaft 4, and prevents particles from entering inside the cover 5. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、半導体ウエハ、液晶表示装置用ガラス基板及びPDP(プラズマディスプレイ)用ガラス基板などの各種基板に対して処理を行う基板処理装置に関する。   The present invention relates to a substrate processing apparatus that performs processing on various substrates such as a semiconductor wafer, a glass substrate for a liquid crystal display device, and a glass substrate for a PDP (plasma display).

液晶ガラス基板等の基板に塵埃などの異物が付着すると、製造工程において液晶分子の配向ムラやシール不良等が発生するため、従来から、液晶表示板の各製造工程の前後で必要に応じて液晶ガラス基板を洗浄するようにしている。この基板洗浄は、基板にシャワー室で洗浄液を吹き付けた後、ブラシ洗浄室において回転ブラシで払拭洗浄し、液切り室で液晶ガラス基板に付着した処理液の液切りを行うようになっている。   If foreign matter such as dust adheres to a substrate such as a liquid crystal glass substrate, liquid crystal molecule alignment unevenness or poor sealing will occur in the manufacturing process. The glass substrate is cleaned. In this substrate cleaning, after a cleaning liquid is sprayed on the substrate in a shower chamber, the substrate is cleaned by wiping with a rotating brush in the brush cleaning chamber, and the processing liquid adhering to the liquid crystal glass substrate is drained in the liquid draining chamber.

このような基板洗浄では、ブラシ洗浄室において、回転ブラシの駆動部(モータ等)は洗浄槽の外部に配設されており、ブラシ回転軸は洗浄槽に設けられた貫通孔から洗浄槽の外部に出され、上記駆動部に連結されているが、ブラシ回転軸を伝って洗浄液が洗浄槽から外部に漏れることを防止するために、例えば、特許文献1に示されるブラシ洗浄装置のように、洗浄槽に設けられた貫通孔の近傍において、回転軸に水切り円板を取り付け、この水切り円板によって、外部への洗浄液の漏れの防止を図っている。
実用新案登録公報第2601663号公報
In such a substrate cleaning, in the brush cleaning chamber, the drive unit (motor, etc.) of the rotating brush is disposed outside the cleaning tank, and the brush rotation shaft is connected to the outside of the cleaning tank through a through hole provided in the cleaning tank. In order to prevent the cleaning liquid from leaking out of the cleaning tank through the brush rotation shaft, for example, as in the brush cleaning device shown in Patent Document 1, In the vicinity of the through hole provided in the cleaning tank, a draining disk is attached to the rotating shaft, and this draining disk prevents leakage of the cleaning liquid to the outside.
Utility Model Registration Gazette No. 2606663

しかしながら、上記のブラシ洗浄装置では、ブラシ回転軸を伝って外部へ流れ出す洗浄液を水切り円板で食い止めることはできるが、洗浄槽内でミスト状となった洗浄液が外部に漏れることまでは防止できない。ここで、ミスト状の洗浄液の外部への漏れを防止する方法として、洗浄槽内から外部への排気量を大きくして、洗浄槽に設けられた上記貫通孔を通して外部から洗浄槽内に向かう気流を作ることが考えられるが、洗浄槽内から外部への排気量を大きくするには、用力コストが高くなるという問題がある。また、このように洗浄槽の貫通孔から洗浄槽内に向かう気流を作ると、外部から洗浄槽内へのパーティクルの浸入を招くことになるため、基板製造の歩留まりが低下する虞がある。   However, in the above brush cleaning apparatus, the cleaning liquid flowing out to the outside through the brush rotation shaft can be stopped by the draining disk, but it cannot be prevented until the cleaning liquid in the mist state leaks to the outside. Here, as a method of preventing leakage of the mist-like cleaning liquid to the outside, an air flow from the outside to the inside of the washing tank through the through hole provided in the washing tank by increasing the exhaust amount from the inside of the washing tank to the outside. However, in order to increase the exhaust amount from the inside of the cleaning tank to the outside, there is a problem that the utility cost becomes high. In addition, when the air flow from the through hole of the cleaning tank into the cleaning tank is generated in this way, particles may enter from the outside into the cleaning tank, which may reduce the yield of manufacturing the substrate.

本発明は、上記の問題を解決するためになされたもので、ミスト状となった洗浄液の外部への漏れを防止でき、しかも、外部からのパーティクルの浸入を招くことがない基板処理装置を提供することを目的とするものである。   The present invention has been made to solve the above-described problem, and provides a substrate processing apparatus that can prevent the mist-like cleaning liquid from leaking to the outside and that does not cause intrusion of particles from the outside. It is intended to do.

本発明の実施形態について図面を用いて説明する。図1は、本発明に係る基板処理装置の第1実施形態である基板洗浄装置の概略構成を示す側面図である。本発明に係る基板処理装置の第1実施形態である基板洗浄装置1は、半導体ウェハ、液晶表示装置用ガラス基板及びPDP(プラズマディスプレイ)用ガラス基板などの基板Wに付着した塵埃などの異物を除去するために洗浄を行うものである。基板洗浄装置1は、基板を搬送させつつブラシ洗浄するものであり、基板に洗浄液を供給しながらブラシ洗浄したり、又は洗浄液が付着している基板をブラシ洗浄するものである。   Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing a schematic configuration of a substrate cleaning apparatus which is a first embodiment of a substrate processing apparatus according to the present invention. A substrate cleaning apparatus 1 which is a first embodiment of a substrate processing apparatus according to the present invention removes foreign matters such as dust attached to a substrate W such as a semiconductor wafer, a glass substrate for a liquid crystal display device and a glass substrate for a PDP (plasma display). Cleaning is performed to remove. The substrate cleaning apparatus 1 performs brush cleaning while transporting a substrate, and performs brush cleaning while supplying a cleaning liquid to the substrate or brush cleaning a substrate to which the cleaning liquid is attached.

基板洗浄装置1は、回転しながら基板Wの表面に接触し、基板Wの表面上に付着している異物を除去するロール状のブラシ(回転体)2を有する。なお、このブラシ2による基板Wの洗浄は、ブラシ2が基板Wの表面に接触せず、僅かに離間した状態で高速に回転して、ブラシ2の表面と、基板Wの表面との間に介在する純水や薬液等の洗浄液によって、いわゆるハイドロプレーン現象を利用して行うものであってもよい。   The substrate cleaning apparatus 1 has a roll-shaped brush (rotary body) 2 that contacts the surface of the substrate W while rotating and removes foreign matters adhering to the surface of the substrate W. The cleaning of the substrate W by the brush 2 is performed at a high speed in a state where the brush 2 is not slightly in contact with the surface of the substrate W and is slightly separated, so that the surface of the brush 2 and the surface of the substrate W are between each other. It may be carried out by utilizing a so-called hydroplane phenomenon with an intervening cleaning liquid such as pure water or chemical liquid.

ブラシ2は、ブラシ2を回転させるための駆動源であるモータ3に連結された回転軸4に取り付けられている。ブラシ2及び基板Wは、洗浄時における洗浄液の周囲への飛散を防止するためにカバー(カバー部材)5に覆われている。回転軸4は、カバー5の両側部に設けられている貫通孔5aを貫通してカバー5の外側まで突出され、軸受部41が図略の支持部材に支持されている。   The brush 2 is attached to a rotating shaft 4 connected to a motor 3 that is a drive source for rotating the brush 2. The brush 2 and the substrate W are covered with a cover (cover member) 5 in order to prevent the cleaning liquid from scattering around the cleaning. The rotary shaft 4 passes through through holes 5a provided on both sides of the cover 5 and protrudes to the outside of the cover 5, and the bearing portion 41 is supported by a support member (not shown).

カバー5の外側は、更にケーシング(ケース部材)6で覆われている。このケーシング6の両側部には、カバー5から突出している回転軸4を貫通させる貫通孔6aが設けられている。このケーシング6の外側における貫通孔6aの周囲は、外部カバー7によって更に覆われている。この外部カバー7の両側部にも、ケーシング6から突出される回転軸4を貫通させる貫通孔7aが設けられている。この外部カバー7の外側において、外部カバー7から突出された回転軸4とモータ3とが連結されている。また、ケーシング6側面の上部には、ケーシング6内の空気を外部に排出するための排気口6bが設けられている。   The outside of the cover 5 is further covered with a casing (case member) 6. On both sides of the casing 6, there are provided through holes 6 a through which the rotating shaft 4 protruding from the cover 5 passes. The periphery of the through hole 6 a outside the casing 6 is further covered with an external cover 7. Both sides of the outer cover 7 are also provided with through holes 7 a through which the rotary shaft 4 protruding from the casing 6 passes. On the outside of the outer cover 7, the rotating shaft 4 protruding from the outer cover 7 and the motor 3 are connected. Further, an exhaust port 6b for discharging the air in the casing 6 to the outside is provided at the upper part of the side surface of the casing 6.

カバー5の外側における各貫通孔5aの近傍には、貫通孔5aを通して回転軸4を伝ってカバー5内部から洗浄液が外部に漏れることを防止するための水切板8が、回転軸4の周面に取り付けられている。この水切板8は、回転軸4と一体的に回転する。さらに、この水切板8よりも外部寄りであって、ケーシング6の内部領域の貫通孔6a近傍には、回転軸4の周面に、回転軸4と一体的に回転するファン(気流発生部材)9が取り付けられている。ファン9は、カバー5の両側部の回転軸4にそれぞれ取り付けられている。   In the vicinity of each through-hole 5 a on the outside of the cover 5, a draining plate 8 for preventing the cleaning liquid from leaking from the inside of the cover 5 through the rotary shaft 4 through the through-hole 5 a is provided on the peripheral surface of the rotary shaft 4. Is attached. The draining plate 8 rotates integrally with the rotating shaft 4. Furthermore, a fan (airflow generating member) that rotates integrally with the rotating shaft 4 on the peripheral surface of the rotating shaft 4 in the vicinity of the through hole 6a in the inner region of the casing 6 and closer to the outside than the draining plate 8. 9 is attached. The fans 9 are respectively attached to the rotary shafts 4 on both sides of the cover 5.

ファン9の構成を説明する。図2はファン9の正面図、図3はファン9の側面図、図4はファン9の斜視図である。図2、図3に示すように、ファン9は、正面視で中心部に開口部91を有する。開口部91の内側には、回転軸4が貫通し、内壁が回転軸4の周面に当接して状態で固定される固定部92が設けられている。また、ファン9は、2つの環状部材931,932を有している。この環状部材931,932は、回転軸4の外周面に直交する姿勢とされている。   The configuration of the fan 9 will be described. 2 is a front view of the fan 9, FIG. 3 is a side view of the fan 9, and FIG. 4 is a perspective view of the fan 9. As shown in FIGS. 2 and 3, the fan 9 has an opening 91 at the center thereof when viewed from the front. Inside the opening 91, there is provided a fixing portion 92 through which the rotating shaft 4 passes and the inner wall is fixed in contact with the peripheral surface of the rotating shaft 4. The fan 9 has two annular members 931 and 932. The annular members 931 and 932 are in a posture orthogonal to the outer peripheral surface of the rotating shaft 4.

固定部92及び環状部材931,932は、その一部が切断された形状とされ、図2の矢印b方向に若干拡げることが可能とされている。固定部92には、ネジ締結部921が設けられており、このネジ締結部921のネジ922を締め付けることによって、ファン9を回転軸4に対して移動不可能な状態で固定することができ、また、ネジ922の締め付けを緩めることによって、ファン9を回転軸4に対して移動可能な状態とすることができるようになっている。   The fixed portion 92 and the annular members 931 and 932 are partially cut off, and can be slightly expanded in the direction of the arrow b in FIG. The fixing portion 92 is provided with a screw fastening portion 921, and by fastening the screw 922 of the screw fastening portion 921, the fan 9 can be fixed in a state where it cannot move with respect to the rotating shaft 4, In addition, the fan 9 can be moved with respect to the rotating shaft 4 by loosening the screw 922.

環状部材931の開口部91は、回転軸4の径よりも大きい径とされている。これにより、回転軸4(固定部92)の周面と開口部91の内縁との間の隙間から、回転軸4の長さ方向におけるファン9の中心部に向かって(固定部92方向)、空気を入り込ませるようになっている。一方、環状部材932には、固定部92のみが設けられ、この固定部92の内壁が回転軸4の周面に密着するようになっている。環状部材932は、回転軸4を貫通させるための孔を有しているが、開口部91は有していない。回転軸4にファン9を取り付けた状態(ネジ締結部921のネジ922を締め付けた状態)では、環状部材931は開口部91により回転軸4の周面との間に隙間が生じ、環状部材932及び固定部92の内壁は回転軸4の周面に密着する。   The opening 91 of the annular member 931 has a diameter larger than the diameter of the rotating shaft 4. Thereby, from the gap between the peripheral surface of the rotating shaft 4 (fixed portion 92) and the inner edge of the opening 91 toward the central portion of the fan 9 in the length direction of the rotating shaft 4 (fixed portion 92 direction), It is designed to let air in. On the other hand, the annular member 932 is provided with only the fixing portion 92, and the inner wall of the fixing portion 92 is in close contact with the peripheral surface of the rotating shaft 4. The annular member 932 has a hole for allowing the rotary shaft 4 to pass therethrough, but does not have the opening 91. In a state where the fan 9 is attached to the rotating shaft 4 (a state where the screw 922 of the screw fastening portion 921 is tightened), a gap is generated between the annular member 931 and the peripheral surface of the rotating shaft 4 by the opening 91, and the annular member 932 is formed. The inner wall of the fixed portion 92 is in close contact with the peripheral surface of the rotating shaft 4.

環状部材931,932の間には、複数の羽根部材94が設けられている。羽根部材94は、回転軸4の長さ方向における各端部が環状部材931又は環状部材932に取り付けられ、また、図2に示すように環状部材931,932の縁部から固定部の外縁にかけて設けられている。この羽根部材94は、図2に示すように、環状部材931,932に対する取り付け角度αが、ファン9が回転軸4と共に図2に示す矢印a方向に回転した場合に、回転軸4の周面に直交する方向であって、回転軸4からその周囲方向に向かう空気流を発生させることが可能な角度に設定されている。   A plurality of blade members 94 are provided between the annular members 931 and 932. Each end of the blade member 94 in the length direction of the rotary shaft 4 is attached to the annular member 931 or the annular member 932, and from the edge of the annular members 931 and 932 to the outer edge of the fixed portion as shown in FIG. Is provided. As shown in FIG. 2, the blade member 94 has a peripheral surface of the rotating shaft 4 when the mounting angle α with respect to the annular members 931 and 932 rotates in the direction of arrow a shown in FIG. The angle is set to an angle at which the airflow from the rotating shaft 4 toward the peripheral direction can be generated.

かかる構成でなるファン9は、開口部91を有する環状部材931側を、カバー5に対向させた状態で、回転軸4に取り付けられている。このファン9が回転軸4と一体的に回転駆動されることによって、カバー5の外側における貫通孔5a近傍の気流を、回転軸4の延びる方向に直交する方向であって、回転軸4の周囲方向に向かう方向に発生するようになっている。   The fan 9 having such a configuration is attached to the rotary shaft 4 with the annular member 931 side having the opening 91 facing the cover 5. When the fan 9 is rotationally driven integrally with the rotary shaft 4, the airflow in the vicinity of the through hole 5 a on the outside of the cover 5 is in a direction orthogonal to the direction in which the rotary shaft 4 extends, and around the rotary shaft 4. It is generated in the direction toward the direction.

上記構成でなる基板洗浄装置1におけるファン9の作用を、従来の基板洗浄装置と比較して説明する。図5は、従来の基板洗浄装置の概略構成を示す側面図である。図5に示す従来の基板洗浄装置100には、ファン9は配設されておらず、カバー5の外側における貫通孔5a近傍、及びケーシング6の外側における貫通孔6a近傍に水切板8が設けられた構成である。   The operation of the fan 9 in the substrate cleaning apparatus 1 configured as described above will be described in comparison with a conventional substrate cleaning apparatus. FIG. 5 is a side view showing a schematic configuration of a conventional substrate cleaning apparatus. In the conventional substrate cleaning apparatus 100 shown in FIG. 5, the fan 9 is not provided, and a draining plate 8 is provided in the vicinity of the through hole 5 a on the outside of the cover 5 and in the vicinity of the through hole 6 a on the outside of the casing 6. It is a configuration.

本発明に係る基板洗浄装置1によって、ブラシ2及び回転軸4を回転させて基板Wを洗浄する場合、まず、この基板Wの洗浄時にカバー5内から回転軸4を伝って漏れ出す洗浄液は、水切板8によって、それよりも外側への漏れが食い止められる。   When cleaning the substrate W by rotating the brush 2 and the rotary shaft 4 by the substrate cleaning apparatus 1 according to the present invention, first, the cleaning liquid leaking from the cover 5 through the rotary shaft 4 when cleaning the substrate W is: The drain plate 8 prevents leakage to the outside.

また、ブラシ2の回転時にミスト状となった洗浄液は、カバー5の貫通孔5aを通ってカバー5の外部に漏れ出すが、ファン9が回転軸4と共に回転しているので、ケーシング6内部におけるファン9の周囲では、回転軸4からその周囲方向に向かう空気流、すなわち、ケーシング6の内壁に沿って流れる空気流が発生している。そのため、ミスト状の洗浄液は、環状部材931の開口部91からファン9の内部に入り込み、羽根部材94により、ケーシング6の内壁に沿って、回転軸4及びケーシング6の貫通孔6aの周囲に向かう方向(図1の矢印f方向)に案内される。   Further, the cleaning liquid that has become mist during the rotation of the brush 2 leaks to the outside of the cover 5 through the through-hole 5a of the cover 5, but the fan 9 rotates together with the rotating shaft 4, so Around the fan 9, an air flow from the rotating shaft 4 toward the peripheral direction, that is, an air flow flowing along the inner wall of the casing 6 is generated. Therefore, the mist-like cleaning liquid enters the inside of the fan 9 from the opening 91 of the annular member 931, and moves toward the periphery of the rotary shaft 4 and the through hole 6 a of the casing 6 along the inner wall of the casing 6 by the blade member 94. It is guided in the direction (arrow f direction in FIG. 1).

これにより、カバー5の貫通孔5aから漏れ出してきたミスト状の洗浄液は、ケーシング6の貫通孔6aに向かうことなく、ケーシング6の内壁に沿って貫通孔6aの上方又は下方に向かうことになる。そのため、ケーシング6内部から排気口6bを通って外部に空気を排出する排気量が小さくても、当該ミスト状の洗浄液を排気口6bから効率よくケーシング6の外部に排出でき、また、貫通孔6aから外部に漏れ出すことも防止できる。   As a result, the mist-like cleaning liquid that has leaked from the through-hole 5a of the cover 5 does not go to the through-hole 6a of the casing 6 but goes to the upper or lower side of the through-hole 6a along the inner wall of the casing 6. . For this reason, even if the exhaust amount of the air discharged from the inside of the casing 6 through the exhaust port 6b to the outside is small, the mist-like cleaning liquid can be efficiently discharged from the exhaust port 6b to the outside of the casing 6, and the through hole 6a. Leakage from the outside can also be prevented.

また、排気口6bからの排気量が少ないと、ケーシング6の貫通孔6aから流入する空気量gが少なくなり、外部からパーティクルが浸入し難くなる。さらに、ファン9によって生成される上記空気流によって、この貫通孔6aを通って外部から浸入してきた空気は、図1に示す矢印f方向に案内されるため、外部から流入してきたパーティクルを、カバー5の貫通孔5aからカバー5内に浸入することを防止することができる。   In addition, when the exhaust amount from the exhaust port 6b is small, the amount of air g flowing from the through hole 6a of the casing 6 is small, and it is difficult for particles to enter from the outside. Furthermore, since the air that has entered from the outside through the through-hole 6a by the air flow generated by the fan 9 is guided in the direction of the arrow f shown in FIG. 1, the particles flowing from the outside are covered. 5 can be prevented from entering the cover 5 from the through hole 5a.

これに対して、従来の基板洗浄装置100は、図5に示すように、ファン9が無いため、ケーシング6内において、本発明に係る基板洗浄装置1のような上記空気流の生成ができない。そのため、カバー5から漏れ出してきたミスト状の洗浄液が、ケーシング6の貫通孔6aから外部に漏れることを防止するには、ケーシング6の排気口6bから外部に排出する排気量を大きくして、貫通孔6aケーシング6内に流入する外部からの空気流hの流量を大きくしてやらなければならないが、この場合、排気口6bからの排気量を大きくするための用力コストが大きくなってしまう。また、上記空気流hにより、外部からパーティクルが浸入しやすい環境を作ってしまうことになる。本発明に係る基板洗浄装置1は、このような大きな用力コストを要しない点、及び、外部からパーティクルが浸入しやすい環境を作らない点において、従来の基板洗浄装置100に対して有利な効果を奏する。   On the other hand, as shown in FIG. 5, the conventional substrate cleaning apparatus 100 does not have the fan 9, and thus cannot generate the air flow in the casing 6 like the substrate cleaning apparatus 1 according to the present invention. Therefore, in order to prevent the mist-like cleaning liquid leaking from the cover 5 from leaking to the outside through the through hole 6a of the casing 6, the exhaust amount discharged to the outside from the exhaust port 6b of the casing 6 is increased, Although the flow rate of the external air flow h flowing into the through hole 6a casing 6 has to be increased, in this case, the cost of utility for increasing the exhaust amount from the exhaust port 6b increases. Further, the air flow h creates an environment in which particles are likely to enter from the outside. The substrate cleaning apparatus 1 according to the present invention has advantageous effects over the conventional substrate cleaning apparatus 100 in that it does not require such a large utility cost and does not create an environment in which particles are likely to enter from the outside. Play.

図6は、ファン9と円盤状部材の排気静圧を比較するグラフを示した図である。上記基板洗浄装置1のように、回転軸4にファン9を設けた場合は、単に円盤状部材(羽根部材94を有しない部材、例えば、上記水切板8等)を回転軸4に設けた場合と比較すると、図6に示すように、ファン9又は円盤状部材とカバー5の外壁との距離が所定距離(例えば、15mm)以内であれば、ファン9を回転軸4に取り付けた方が、円盤状部材を取り付けた場合よりも排気静圧が高くなり、ファン9によって生成される気流の影響で排気抵抗が大きくなる。これにより、ファン9を回転軸4に取り付けることによって、ケーシング6内から排気口6bを通して外部に排出する排気量を低減することが可能となる。ファン9の回転軸4への取り付け位置を、カバー5の外壁に近い位置に設定すれば、静圧向上に効果的である。また、カバー5の組み立て誤差や設計上の都合等により、カバー5の外壁とファン9との距離を小さくすることができない場合であっても、上記構成でなるファン9を用いることで、若干は静圧を向上させることが可能となる。   FIG. 6 is a diagram showing a graph comparing the exhaust static pressure of the fan 9 and the disk-shaped member. When the fan 9 is provided on the rotating shaft 4 as in the substrate cleaning apparatus 1, a disk-like member (a member not having the blade member 94 such as the draining plate 8) is simply provided on the rotating shaft 4. 6, if the distance between the fan 9 or the disk-shaped member and the outer wall of the cover 5 is within a predetermined distance (for example, 15 mm), as shown in FIG. The exhaust static pressure becomes higher than when a disk-shaped member is attached, and the exhaust resistance increases due to the influence of the airflow generated by the fan 9. Thereby, by attaching the fan 9 to the rotating shaft 4, it becomes possible to reduce the exhaust amount discharged | emitted outside from the inside of the casing 6 through the exhaust port 6b. Setting the attachment position of the fan 9 to the rotating shaft 4 to a position close to the outer wall of the cover 5 is effective in improving the static pressure. Further, even if the distance between the outer wall of the cover 5 and the fan 9 cannot be reduced due to the assembly error of the cover 5 or the design convenience, the use of the fan 9 having the above-described configuration slightly increases It becomes possible to improve static pressure.

本発明に係る基板洗浄装置1の第2実施形態を説明する。図7は、本発明に係る基板処理装置の第2実施形態に係る基板洗浄装置の概略構成を示す側面図である。この第2実施形態に係る基板洗浄装置10は、ファン9が、ケーシング6の外側における貫通孔6aの近傍であって外部カバー7の内部に回転軸4に取り付けられている。この第2実施形態に係る基板洗浄装置10のファン9は、開口部91を有する環状部材931を外側方向(カバー5及びケーシング6とは反対側方向)に向けて取り付けられる。すなわち、環状部材931の開口部91が外部カバー7の貫通孔7aに対向する状態で、ファン9が回転軸4に取り付けられている。   A second embodiment of the substrate cleaning apparatus 1 according to the present invention will be described. FIG. 7 is a side view showing a schematic configuration of the substrate cleaning apparatus according to the second embodiment of the substrate processing apparatus of the present invention. In the substrate cleaning apparatus 10 according to the second embodiment, the fan 9 is attached to the rotary shaft 4 in the vicinity of the through hole 6 a on the outside of the casing 6 and inside the outer cover 7. The fan 9 of the substrate cleaning apparatus 10 according to the second embodiment is attached with an annular member 931 having an opening 91 facing outward (a direction opposite to the cover 5 and the casing 6). That is, the fan 9 is attached to the rotating shaft 4 with the opening 91 of the annular member 931 facing the through hole 7 a of the outer cover 7.

上記のようにして回転軸4に取り付けられたファン9は、外部カバー7の貫通孔7aから外部空気が浸入してくると、図7に示す方向に向かう空気流iを発生させる。この基板洗浄装置10の場合、ファン9がケーシング6の外側で回転軸4と一体的に回転し、ケーシング6外側における貫通孔6a近傍の空気を、ケーシング6の外壁に沿って回転軸4の周囲に向かわせる気流を発生させるので、ケーシング6の外側における貫通孔6a近傍において、ケーシング6の外壁に沿って流れるエアカーテンが生成される。そのため、外部カバー7の貫通孔7aを通って浸入してきた外部空気を、上記エアカーテンによって、空気流iとしてケーシング6の外壁に沿って案内できるので、ケーシング6内部に入り込む外部空気流jの量を低減でき、ケーシング6内に入り込むパーティクルの量を低減できる。また、ケーシング6の貫通孔6aを通ってケーシング6の外部に向かおうとするミスト状の洗浄液は、その進行が上記エアカーテンに遮られるため、ケーシング6から外部へのミスト状洗浄液の漏れを低減することができる。   The fan 9 attached to the rotating shaft 4 as described above generates an air flow i in the direction shown in FIG. 7 when external air enters from the through hole 7a of the external cover 7. In the case of this substrate cleaning apparatus 10, the fan 9 rotates integrally with the rotary shaft 4 outside the casing 6, and the air in the vicinity of the through hole 6 a outside the casing 6 is moved around the rotary shaft 4 along the outer wall of the casing 6. An air curtain that flows along the outer wall of the casing 6 is generated in the vicinity of the through hole 6 a on the outside of the casing 6. Therefore, since the external air that has entered through the through hole 7a of the external cover 7 can be guided along the outer wall of the casing 6 as the air flow i by the air curtain, the amount of the external air flow j that enters the inside of the casing 6 And the amount of particles entering the casing 6 can be reduced. In addition, the mist-like cleaning liquid that is going to the outside of the casing 6 through the through-hole 6a of the casing 6 is blocked by the air curtain so that the leakage of the mist-like cleaning liquid from the casing 6 to the outside is reduced. can do.

なお、本発明は上記実施の形態の構成に限られず種々の変形が可能である。例えば、上記各実施形態では、回転軸4及びブラシ2が水平方向に延びるようにして設けられているが、回転軸4及びブラシ2を傾斜させた姿勢で設けるようにしてもよい。すなわち、回転軸4の一方端側の高さと、他方端側の高さとを異ならせてもよい。これによれば、基板Wに対して供給された洗浄液を、上記傾斜によって一定方向(基板Wの低い方)に流れるように案内できるので、基板Wの表面全域における均一な洗浄液の供給、及び円滑な洗浄液の排除が可能となる。この場合、傾斜姿勢となっている回転軸4及びブラシ2の下方側となる端部付近にミスト状洗浄液が集まりやすくなるが、上述したファン9による空気流の案内により、外部へのミスト状洗浄液の漏れを低減できるため、シール性を向上させることができる。   The present invention is not limited to the configuration of the above embodiment, and various modifications can be made. For example, in each of the above embodiments, the rotation shaft 4 and the brush 2 are provided so as to extend in the horizontal direction, but the rotation shaft 4 and the brush 2 may be provided in an inclined posture. That is, the height on the one end side of the rotation shaft 4 may be different from the height on the other end side. According to this, the cleaning liquid supplied to the substrate W can be guided so as to flow in a certain direction (the lower side of the substrate W) by the inclination, so that the cleaning liquid can be supplied uniformly over the entire surface of the substrate W and smoothly Can be eliminated. In this case, the mist-like cleaning liquid tends to gather near the rotating shaft 4 and the lower end of the brush 2 in the inclined posture, but the mist-like cleaning liquid to the outside is guided by the air flow guidance by the fan 9 described above. Therefore, sealing performance can be improved.

また、上記実施形態では、ブラシ2をロールブラシとしているが、ブラシ2を片持ちのディスクブラシからなるものとしてもよい。   In the above embodiment, the brush 2 is a roll brush, but the brush 2 may be a cantilever disk brush.
