Description
前記流量調整手段は、前記循環ラインに設けられた電動流量調整弁であるのが望ましい。
図1は、第1の実施形態に係る基板処理システムの概略構成図である。この基板処理システムは、洗浄液供給装置1と、循環ライン21と、複数の分岐管22a,22bと、循環制御ユニット3と、複数の洗浄液供給ユニット4と、そのそれぞれと対応する複数の基板洗浄ユニット5と、制御部6とを備えている。
次に説明する第2の実施形態は、基板洗浄ユニット5のメンテナンス性を向上させるものである。
次に説明する第3の実施形態は、洗浄液供給装置1と循環ライン21との接続を変えることなく、循環ライン21内を純水で置換できるようにするものである。図1Aに示すように、1つの洗浄液供給装置1に複数の基板処理装置100が接続され得る。基板処理装置100をメンテナンスする際、基板処理装置100内の配管などに残っている洗浄液を純水で置換する必要がある。図1Aに示すような基板処理システムの場合、ある1つの基板処理装置100をメンテナンスするために、洗浄液供給装置1から洗浄液ではなく純水を基板処理装置100に供給しなければならない。そうすると、循環ライン21に純水が流れることになるので、メンテナンス対象でない基板処理装置100にも洗浄液を供給できなくなるため使用を停止せざるを得ない。
