Description
前記薬液槽を複数用い、該複数の薬液槽に含まれるSC−2溶液のうち、最後に用いる薬液槽に含まれるSC−2溶液中のHCl濃度を最も低くして前記半導体ウェーハを洗浄することを特徴とする半導体ウェーハの洗浄方法を提供する。
図1に示すフロー図に従って鏡面研磨後の直径300mmボロンドープp型単結晶シリコンウェーハを洗浄した。なお、以下に示す実施例及び比較例において、洗浄は、シリコンウェーハ25枚を1バッチとして処理した。
二段目のSC−2洗浄におけるHCl濃度を0.04質量%に変更したこと以外、実施例1と同様の手順で、シリコンウェーハを洗浄した。
二段目のSC−2洗浄におけるHCl濃度を0.01質量%に変更したこと以外、実施例1と同様の手順で、シリコンウェーハを洗浄した。
二段目のSC−2洗浄におけるHCl濃度を0.01質量%に変更し、H2O2濃度を0.1質量%に変更したこと以外、実施例1と同様の手順で、シリコンウェーハを洗浄した。
図10に示すフロー図に従って実施例1と同様のシリコンウェーハを洗浄した。具体的には、二段目のSC−2洗浄におけるHCl濃度を0.4質量%に変更した(HCl濃度を一段目、二段目共に0.4質量%とした)こと以外、実施例1と同様の手順で、シリコンウェーハを洗浄した。
図13に示すフロー図に従って実施例1と同様のシリコンウェーハを洗浄した。具体的には、二段目のSC−2洗浄を行わない(SC−2槽を一槽のみ用いる)こと以外、実施例1と同様の手順で、シリコンウェーハを洗浄した。
