Description
以下、本発明を枚葉式の超音波洗浄装置に適用した場合の第1実施形態について、図1を参照しながら説明する。本実施形態の超音波洗浄装置は、ウエハ(半導体基板)1を回転させる回転ユニット2と、ウエハ1上に薬液(洗浄液またはリンス液等)を吐出する吐出ノズル3と、この吐出ノズル3に薬液を供給する薬液供給ユニット4と、この薬液供給ユニット4内の薬液に含まれる水分の濃度を検出する水分濃度計(水分濃度検出装置)5と、超音波洗浄装置の各部を制御する制御装置6とを備えて構成されている。
図3は、本発明の第2実施形態を示すものである。尚、第1実施形態と同一構成には、同一符号を付している。第2実施形態の超音波洗浄装置は、複数枚のウエハ1を同時に洗浄するバッチ式の超音波洗浄装置である。第2実施形態の超音波洗浄装置は、ウエハカセット(図示しない)に収容された複数枚のウエハ1を洗浄処理する処理槽25と、処理槽25に薬液を循環供給する循環供給ユニット26と、処理槽25内の薬液に含まれる水分の濃度を検出する水分濃度計5と、超音波洗浄装置の各部を制御する制御装置6とを備えて構成されている。
本発明は、上記実施形態にのみ限定されるものではなく、次のように変形または拡張できる。
Claims (3)
- 半導体基板を薬液を用いて洗浄する半導体基板の洗浄装置であって、
前記薬液に含まれる水分の濃度を検出する水分濃度検出装置と、
前記薬液または前記半導体基板に超音波を印加して超音波洗浄を実行する超音波振動子と、
前記水分濃度検出装置により検出された前記水分の濃度が所定値より高くなると水分の濃度が所定値以下である薬液に交換して超音波洗浄を実行させる制御装置とを備えたことを特徴とする半導体基板の洗浄装置。 - 超音波振動子により薬液または半導体基板に超音波を印加しつつ、半導体基板に形成されたホールまたはスペース内に水の表面張力よりも小さい表面張力を有する第1の薬液を浸透させた後前記ホールまたはスペース内の前記第1の薬液を第2の薬液に置換して前記ホールまたはスペース内をリンス、乾燥させ、前記ホールまたはスペース内を超音波洗浄する半導体基板の洗浄方法であって、
水分濃度検出装置により前記薬液に含まれる水分の濃度を検出し、前記検出された水分濃度に基づいて前記超音波振動子をオンオフするまたは前記超音波洗浄の洗浄条件を変えることを特徴とする半導体基板の洗浄方法。 - 前記薬液には、イソプロピルアルコールが含まれていることを特徴とする請求項2記載の半導体基板の洗浄方法。
