Description

【0001】
【発明の属する技術分野】
この発明は、液晶表示装置用ガラス基板、プラズマディスプレイ用ガラス基板、プリント基板、半導体ウエハ等の基板の表面にエッチング液、現像液等の処理液を供給して基板に対しエッチング処理、現像処理等の処理を行う基板処理装置に関する。
【0002】
【従来の技術】
基板の表面へエッチング液、現像液等の処理液を供給して基板を1枚ずつ処理する枚葉式の基板処理装置において、むらのない均一な基板処理を行うためには、基板表面へ供給する処理液の温度を一定に保つことは勿論のこと、基板の全面にわたって温度を均一に保つ必要がある。すなわち、基板の表面に温度むらが発生すると、基板の表面上の位置によってエッチング、現像等の処理速度に差を生じ、それが処理むらを引き起こす原因となるからである。
【0003】
基板の温度を全面にわたり均一に保って処理むらの発生を防止する手段として、例えば、処理槽内で基板を搬送ローラによって搬送しつつ、基板搬送路の上方に配置されたシャワー部から処理液を基板の表面に向かって吐出する装置において、シャワー部から基板上へ吐出され基板から垂れ落ちる余剰処理液を受けて溜める上面開口の処理液貯留槽を設けた装置構成が提案されている。このような構成により、基板から垂れ落ちて処理液貯留槽内に一時的に貯留された処理液から放出される輻射熱により、基板の温度を均一に調節して、処理むらの原因となる基板面の温度むらの発生を防止するようにしている(例えば、特許文献1参照。)。
【0004】
上記した基板処理装置は、基板を搬送しつつシャワー部から基板の表面へ処理液を吐出して基板表面を処理するものであるが、パドル方式と呼ばれる方式を用いた基板処理装置では、図5に模式的側面図を示すように、基板Wの表面へ処理液を供給して基板Wの表面全体に処理液1を盛ってから、液盛りされた基板Wを、互いに平行に基板搬送路に沿って配列された複数本の搬送ローラ2により支持して移動、例えば直線的に往復移動(水平面内において揺動)させながら、その間にエッチング、現像等の反応を進行させて基板表面の処理が行われる。このパドル式基板処理装置では、基板Wの表面へ供給される処理液の温度は一定に保たれ、その処理液が基板Wの表面全体に盛られるため、液盛り時点において基板Wの温度は全面にわたって均一である。
【0005】
【特許文献1】
特開2002−361159号公報(第3頁、図1)
【0006】
【発明が解決しようとする課題】
ところが、パドル式基板処理装置では、搬送ローラ2の温度が処理液1の温度(例えば40℃)より低いために、液盛りされた基板Wの下面が搬送ローラ2と当接することにより、基板Wおよび処理液の温度が低下する。この場合、基板Wの全面にわたって均一に温度が低下すれば、それほど問題とはならない。ところが、図6に平面図を示すように、液盛りされた基板Wは、通常、複数本の搬送ローラ2によって往復移動させられながら処理が行われる。このとき、基板Wは、基板搬入時や基板反転時に僅かな時間であるが停止状態となる。この基板停止時に、基板Wの、搬送ローラ2と接触している部分は、他の部分より温度が低下することとなる。また、基板Wの、基板搬送方向における両端部の領域は、他の領域に比べて搬送ローラ2と接触している時間が短くなる。このため、基板面上の位置によって温度低下の程度に差を生じ、この結果、基板面上の位置によってエッチング、現像等の処理速度に差を生じて処理むらを引き起こす、といった問題点がある。
【0007】
また、図7に示すように、回転支軸4の両端部に基板Wの左・右両端縁部を支持する両端支持部5を有するとともに回転支軸4の軸線方向に間隔をあけて複数の中間支持部6を有する搬送ローラ3を備えた装置では、両端支持部5および中間支持部6と接触する基板Wの部分における温度が非接触部分における温度に比べて低下する。このため、基板Wを連続的に一方向へ搬送しつつ基板Wの処理を行う場合であっても、両端支持部5および中間支持部6と接触する部分におけるエッチングレートや現像反応速度が遅くなって、処理後の基板には、複数本の線状の処理むらが発生することとなる。
【0008】
この発明は、以上のような事情に鑑みてなされたものであり、パドル方式を採用した基板の処理において、基板の温度を均一に保って処理むらの発生を防止することができる基板処理装置を提供することを目的とする。

【0021】
【発明の実施の形態】
以下、この発明の好適な実施形態について図1ないし図4を参照しながら説明する。
【0022】
図1は、第1の発明の1実施形態を示し、基板処理装置の概略構成の1例を示す模式図である。この基板処理装置は、例えば基板のエッチング処理を行うための装置であって、互いに平行に基板搬送路に沿って配列された複数本の搬送ローラ10を備えており、これら複数本の搬送ローラ10により、基板Wが支持されて直線的に往復移動(水平面内において揺動)させられるようになっている。基板搬送路の一端側には、基板搬送路の直上位置に、下端面にスリット状吐出口が形設された液供給ノズル12が配設されている。また、基板搬送路の下方には、エッチング液を回収するための液回収槽14が配設されている。
【0022】
液供給ノズル12には、液供給用配管16が連通接続されており、液供給用配管16は、エッチング液18が貯留された液貯留槽20に流路接続されている。液供給用配管16には、送液用ポンプ22が介挿設置されており、また、フィルタ24および開閉制御弁26がそれぞれ介挿されている。そして、開閉制御弁26を開くことにより、液貯留槽20内からエッチング液18がポンプ22によって液供給用配管16を通り液供給ノズル12へ供給され、液供給ノズル12のスリット状吐出口からエッチング液がカーテン状に吐出されて、液供給ノズル12の直下を通過する基板Wの表面全体にエッチング液が盛られる。また、液回収槽14の底部には、回収用配管28が連通接続されており、回収用配管28の先端出口は、液貯留槽20内に配置されている。
【0023】
液貯留槽20には、その底部に一端口が連通接続され他端口が液貯留槽20内に配置された液循環用配管30が付設されている。この液循環用配管30には、液循環用ポンプ32が介挿設置されており、また、ヒータ34が介挿されている。そして、液貯留槽20に貯留されたエッチング液18を、液循環用配管30を通して循環させることにより、エッチング液は、ヒータ34の内部を流通する際に加温され、コントローラ(図示せず)によってヒータ34を制御することにより、液貯留槽20内のエッチング液18の温度が一定温度、例えば40℃に調節されるようになっている。なお、液貯留槽20内のエッチング液18を一定温度に調節して保持する手段は、図示例の構成のものに限らない。
【0024】
各搬送ローラ10は、正・逆方向にそれぞれ回転可能であり、基板の処理中においては、基板搬入時や基板反転時の僅かな時間を除いて常時回転駆動している。各搬送ローラ10の直下には、液溜め容器36がそれぞれ配設されている。各液溜め容器36には、液供給用配管16からフィルタ24と開閉制御弁26との間で分岐した分岐配管38がそれぞれ連通接続されている。そして、基板の処理中においては、液貯留槽20内から一定温度に調節されたエッチング液が液供給用配管16および分岐配管38を通り各液溜め容器36内へ連続してそれぞれ供給され、各液溜め容器36内からエッチング液がそれぞれ溢れ出ている状態とされる。液溜め容器36内から溢れ出たエッチング液は、液回収槽14内に流下し、液回収槽14内から回収用配管28を通って液貯留槽20内に戻される。
【0025】
液溜め容器36は、図2に斜視図を示すように、その内部に貯留されたエッチング液中に搬送ローラ10の周面の一部がその全長にわたって浸漬されるような形状および大きさを有している。なお、図示例の装置では、搬送ローラ10ごとに液溜め容器36を設けているが、複数本の搬送ローラ10ごとに大き目の液溜め容器を設けて、1つの液溜め容器内に貯留されたエッチング液中に複数本の搬送ローラ10を浸漬させるようにしてもよいし、また、大型の液溜め容器を設けて、1つの液溜め容器内に貯留されたエッチング液中に全部の搬送ローラ10を浸漬させるようにしてもよい。
【0026】
上記した構成を備えた基板処理装置を使用して基板をエッチング処理するときは、各液溜め容器36内に貯留された一定温度のエッチング液中に各搬送ローラ10の周面の一部がそれぞれ浸漬されるとともに、その状態で各搬送ローラ10が常時それぞれ回転することにより、基板W上に盛られたエッチング液と同等の温度に各搬送ローラ10の周面全体がそれぞれ加温される。このため、液盛りされた基板Wが搬送ローラ10と接触しても、基板Wおよびその表面全体に盛られたエッチング液の温度が低下することはない。したがって、基板Wの温度は全面にわたって均一となり、温度むらが発生することがないので、基板Wの表面全体にわたってエッチングレートが均一となり、処理むらを生じる恐れがない。
【0027】
次に、図3は、第2の発明の実施形態を示し、基板処理装置の搬送ローラ付近を示す斜視図である。この実施形態では、搬送ローラ10の近傍に吐出口が配置された吐出ノズル40を設けている。装置の全体構成は、図1に示した装置と同様であるが、液溜め容器36を設置せずに、液供給用配管16から分岐した分岐配管38を吐出ノズル40に連通接続する。
【0028】
このような構成を備えた装置では、一定温度に調節されたエッチング液が吐出ノズル40へ供給され、吐出ノズル40の吐出口から常時回転している搬送ローラ10の周面へ一定温度のエッチング液が吐出されることにより、基板W上に盛られたエッチング液と同等の温度に搬送ローラ10の周面全体が加温されることとなる。このため、液盛りされた基板Wが搬送ローラ10と接触しても、基板Wおよびその表面全体に盛られたエッチング液の温度が低下することがなくなり、基板Wの温度は全面にわたって均一となる。したがって、エッチングレートが基板Wの表面全体にわたって均一となり、処理むらの発生が防止される。なお、吐出ノズル40から搬送ローラ10の周面へ吐出されて搬送ローラ10の周面から垂れ落ちたエッチング液は、液回収槽14内に流下し、液回収槽14内から回収用配管28を通って液貯留槽20内に戻される。
【0029】
また、図4は、第3の発明の実施形態を示し、基板処理装置の搬送ローラを、一部破断した状態で示す斜視図である。この搬送ローラ42は、その内部に液体通路44が形成されている。また、搬送ローラ42の左・右の各回転支軸46a、46bの軸心部にも、液体通路44に連通する液体通路(図示せず)がそれぞれ形成されている。そして、一方の回転支軸46aは、ロータリジョイント48aに接続され、回転支軸46aの液体通路は、ロータリジョイント48aを介して、加温用液体、例えば温水の供給装置(図示せず)に接続された温水供給管50に流路接続されている。また、他方の回転支軸46bは、ロータリジョイント48bに接続され、回転支軸46bの液体通路は、ロータリジョイント48bを介して排水管52に流路接続され、排水管52は、温水供給装置に流路接続されている。
【0030】
このような構成の搬送ローラ42を備えた基板処理装置では、温水供給装置から一定温度、例えば40℃に調節された温水が、温水供給管50を通って搬送ローラ42の内部の液体通路44へ供給され、液体通路44内に温水が流されることにより、基板W上に盛られたエッチング液と同等の温度に搬送ローラ42の全体が加温される。そして、液体通路44内を流れる間に熱交換によって温度が低下した温水は、液体通路44内から排出されて、排水管52を通り温水供給装置へ戻され、加温されて循環使用される。このように、搬送ローラ42がその内部から加温されることにより、液盛りされた基板Wが搬送ローラ42と接触しても、基板Wおよびその表面全体に盛られたエッチング液の温度が低下することがなくなり、基板Wの温度は全面にわたって均一となる。したがって、エッチングレートが基板Wの表面全体にわたって均一となり、処理むらが発生することがない。
【0031】
なお、上記した実施形態では、エッチング処理を行う基板処理装置を例にとって説明したが、それ以外の基板処理装置、例えば現像処理を行う基板処理装置についてもこの発明は適用し得る。
【0032】
【発明の効果】
請求項1ないし請求項3に係る発明の基板処理装置を使用すると、パドル方式での基板の処理において、基板の温度を全面にわたって均一に保つことができ、このため、基板の温度むらに起因する処理むらの発生を防止することができる。
【0033】
そして、請求項1および請求項2に係る各発明の装置では、搬送ローラの周面全体を、基板上に盛られた処理液と同等の温度に確実に加温することができる。
【0034】
また、請求項3に係る発明の装置では、搬送ローラ全体を、基板上に盛られた処理液と同等の温度に確実に加温することができる。
【0035】
請求項4に係る発明の装置では、基板の表面へ供給される処理液と同じ処理液を加温用液体として使用することができる。

BACKGROUND OF THE INVENTION
The present invention supplies an etching solution, a developing solution, etc. to the surface of a substrate such as a glass substrate for a liquid crystal display device, a glass substrate for a plasma display, a printed substrate, a semiconductor wafer, etc. the process relating to the line power sale board processor.
[0002]
[Prior art]
In a single-wafer type substrate processing apparatus that supplies a processing solution such as an etching solution or a developing solution to the surface of the substrate and processes the substrates one by one, in order to perform uniform substrate processing without unevenness, supply the substrate surface. In addition to keeping the temperature of the processing solution to be constant, it is necessary to keep the temperature uniform over the entire surface of the substrate. That is, if temperature unevenness occurs on the surface of the substrate, the processing speed such as etching and development varies depending on the position on the surface of the substrate, which causes processing unevenness.
[0003]
As a means for preventing the occurrence of processing unevenness by keeping the temperature of the substrate uniform over the entire surface, for example, while the substrate is transported by a transport roller in the processing tank, the processing liquid is supplied from the shower unit disposed above the substrate transport path. In an apparatus for discharging toward the surface of a substrate, an apparatus configuration has been proposed in which a processing liquid storage tank having an upper surface opening for receiving and storing surplus processing liquid discharged from the shower unit onto the substrate and dripping from the substrate has been proposed. With such a configuration, the substrate surface that causes processing unevenness by uniformly adjusting the temperature of the substrate by the radiant heat released from the processing liquid dripping from the substrate and temporarily stored in the processing liquid storage tank. The temperature unevenness is prevented from occurring (see, for example, Patent Document 1).
[0004]
The substrate processing apparatus described above is for processing the substrate surface by discharging the processing liquid from the shower unit to the surface of the substrate while transporting the substrate. In the substrate processing apparatus using a system called a paddle system, FIG. As shown in the schematic side view, after supplying the processing liquid to the surface of the substrate W and depositing the processing liquid 1 on the entire surface of the substrate W, the stacked substrates W are parallel to each other on the substrate transport path. The substrate surface is processed by supporting a plurality of transport rollers 2 arranged along, for example, reciprocating linearly (oscillating in a horizontal plane) while advancing reactions such as etching and development. Done. In this paddle type substrate processing apparatus, the temperature of the processing liquid supplied to the surface of the substrate W is kept constant, and the processing liquid is deposited on the entire surface of the substrate W. Uniform over.
[0005]
[Patent Document 1]
JP 2002-361159 A (3rd page, FIG. 1)
[0006]
[Problems to be solved by the invention]
However, in the paddle type substrate processing apparatus, since the temperature of the transport roller 2 is lower than the temperature of the processing liquid 1 (for example, 40 ° C.), the bottom surface of the liquid-filled substrate W comes into contact with the transport roller 2, thereby In addition, the temperature of the treatment liquid decreases. In this case, if the temperature is lowered uniformly over the entire surface of the substrate W, there will be no problem. However, as shown in the plan view of FIG. 6, the liquid-filled substrate W is usually processed while being reciprocated by a plurality of transport rollers 2. At this time, the substrate W is in a stopped state for a short time when the substrate is carried in or when the substrate is reversed. When the substrate is stopped, the temperature of the portion of the substrate W that is in contact with the transport roller 2 is lower than that of the other portions. In addition, the region of both ends of the substrate W in the substrate transport direction is shorter in contact with the transport roller 2 than the other regions. For this reason, there is a problem in that the degree of temperature drop varies depending on the position on the substrate surface, and as a result, the processing speed such as etching and development varies depending on the position on the substrate surface, thereby causing uneven processing.
[0007]
Further, as shown in FIG. 7, both end portions of the rotation support shaft 4 have both end support portions 5 that support the left and right edge portions of the substrate W, and a plurality of the support shafts 4 are spaced apart in the axial direction of the rotation support shaft 4. In the apparatus including the transport roller 3 having the intermediate support portion 6, the temperature at the both-end support portion 5 and the portion of the substrate W in contact with the intermediate support portion 6 is lower than the temperature at the non-contact portion. For this reason, even in the case where the substrate W is processed while continuously transporting the substrate W in one direction, the etching rate and the development reaction speed in the portion in contact with the both-end support part 5 and the intermediate support part 6 are slow. Thus, a plurality of linear processing irregularities occur on the substrate after processing.
[0008]
The present invention has been made in view of the circumstances as described above, in the processing of substrates employing the paddle method, board processing where Ru can be prevented the occurrence of processing unevenness while maintaining the temperature of the substrate uniform An object is to provide an apparatus.
[0009]
[Means for Solving the Problems]
