Description
このめっき装置によれば、擬似陰極34の電位を調節することで、基板Wの表面に形成される金属膜の膜厚の均一性を改善することができる。
凹凸を、三角形または矩形が連続する鋸歯状、または多数の細い溝を所定の間隔で形成した形状とすることにより、攪拌翼の往復運動によって、多くの渦流を均一に且つ全般的に発生させためっき液の流れを生じさせ、被めっき材の被めっき面に接するめっき液の流れを均一に且つ効果的に作用させることで、被めっき材の被めっき面上に膜厚の均一性が良好なめっき膜を形成できる。
攪拌翼の凹凸が形成された辺を、被めっき材の被めっき面に対向させることにより、攪拌翼の往復運動によって、多くの渦流を被めっき材の被めっき面近傍に均一に且つ全般的に発生させためっき液の流れを生じさせ、被めっき材の被めっき面に接するめっき液の流れを均一に且つ効果的に作用させて、被めっき材の被めっき面上により膜厚の均一性が良好なめっき膜を形成できる。
攪拌機構の攪拌翼を複数とすることにより、攪拌翼の往復運動によって、より多くの渦流を被めっき材の被めっき面近傍に均一に且つ全般的に発生させためっき液の流れを生じさせ、被めっき材の被めっき面に接するめっき液の流れを均一に且つ効果的に作用させることで、被めっき材の被めっき面上により膜厚の均一性が良好なめっき膜を形成できる。
一方、めっき処理後の基板を装着しストッカ164に戻した基板ホルダ160を第2搬送ロボット174aで2基同時に把持し、前記と同様にして、基板脱着台162上に載置する。
Claims (3)
- 内部にめっき液を供給するめっき液供給口を底部に有し内部にめっき液を保持するめっき槽と、
被めっき材を保持し前記めっき槽内のめっき液に浸漬させて鉛直方向に配置するホルダと、
前記めっき槽内のめっき液中に浸漬されて該めっき液を攪拌する攪拌翼を備えた攪拌機構とを有し、
前記攪拌翼は、前記めっき槽の上部から底部に向かって鉛直に延びる板状部材からなり、被めっき材の被めっき面と対向する位置に配置され該被めっき面に平行に横方向に往復運動してめっき液を攪拌するように構成され、
前記攪拌翼の前記被めっき材と対向する辺には、該攪拌翼の往復運動に伴ってめっき液中に渦流を発生させる凹凸が形成されていることを特徴とするめっき装置。 - 前記攪拌翼に形成された凹凸は、三角形または矩形が連続する鋸歯状、または多数の細い溝を所定の間隔で形成した形状であることを特徴とする請求項1記載のめっき装置。
- 前記攪拌機構は、複数の攪拌翼を有することを特徴とする請求項1または2記載のめっき装置。
