Description
第1シークエンスSE1の後、ウェット剥離工程の第2シークエンスSE2が実行される。第2シークエンスSE2は、第2剥離工程S6、第2リンス工程S7及び第2乾燥工程S8を含む。
第2シークエンスSE2の後、ウェット剥離工程の第3シークエンスSE3が実行される。第3シークエンスSE2は、第3剥離工程S9、第3リンス工程S10及び第3乾燥工程S11を含む。
以上のウェット剥離工程が終わった後、設計に従って金属配線膜上に絶縁膜が成膜される(S12)。
リンス液(例示:超純水)が基板の表面に供給される。図9の例では、基板の表面に対してリンス液が供給される期間の長さが11秒、基板の裏面に対してバックリンス液が供給される期間の長さが16秒である。この第7動作は、図8における第1リンス工程S4に対応する。ウェハ上に残った剥離された堆積物や薬液をウェハ外に完全に振り切るためには、この動作における中速回転の持続時間は10秒以上に設定されることが望ましい。
25℃:デポ物残りポイント数14
35℃:デポ物残りポイント数4
45℃:デポ物残りポイント数7
薬液の温度が25℃に設定された場合に比べて35℃または45℃に設定された場合の方が洗浄効果が高い。特に薬液の温度が35℃付近に設定されることが望ましい。
