Description
図1および図3を用いて、本発明の一実施形態に従うシリコンウェーハの片面研磨方法を説明する。本発明の一実施形態では、酸化シリコン膜20がベアなシリコン10の表面に形成されたシリコンウェーハWを研磨ヘッドにより把持し、研磨布が貼付された回転定盤にシリコンウェーハWを回転させながら押圧して、シリコンウェーハWの前記回転定盤側の片面を研磨する。
直径300mm、総厚み775μm(内、自然酸化膜の厚み:1nm)である同種のシリコンウェーハを複数用意し、スウェード素材の研磨布を定盤の表面に設置し、アルカリ研磨液を研磨スラリーとして供給しながら、バッチ式の片面研磨装置を用いて化学機械研磨による仕上げ研磨を行った。なお、研磨ヘッドおよび回転定盤の回転数は同一とし、同方向に回転させた。そして、回転定盤にシリコンウェーハを押圧する際の加圧力(g/cm2)ならびに、研磨ヘッドおよび回転定盤の回転数(rpm)のみを以下の条件で変化させた。すなわち、片面研磨装置100において、研磨ヘッドおよび回転定盤の回転数(rpm)を16,24,43,55とし、それぞれの回転数の下、加圧力(g/cm2)を50,60,100,150,200と変化させた。そして、研磨の取り代からSiO2研磨レートおよびSi研磨レート(nm/s)をそれぞれ求めた。このようにして求めたSiO2研磨レートおよびSi研磨レートから、SiO2/Si研磨レート比を求めた。結果を図7に示す。
予備実験例において用いたシリコンウェーハと同種のシリコンウェーハに対して、下記表1に示す研磨条件により第1研磨工程および第2研磨工程を行った。さらに、第2研磨工程後に、純水による研磨後のシリコンウェーハの洗浄工程を行った。その他の条件は予備実験例と同様にして、100枚のシリコンウェーハの片面研磨を行った。なお、表1中、SiO2/Si研磨レート比を単に「研磨レート比」と記載している。また、第1研磨工程におけるSiO2研磨レートは1nm/minであるため、60秒の研磨により酸化シリコン膜の全てが除去されたと考えてよい。また、第1研磨工程と第2研磨工程とでSiO2/Si研磨レート比は異なるが、第1研磨工程では低加圧且つ高速回転であり、第2研磨工程では高加圧且つ低速回転であるため、両研磨工程におけるSiO2研磨レートは同程度であった。
実施例1における第1研磨工程を行わず、研磨条件を表1に記載のとおりとした以外は、実施例1と同様にして、100枚のシリコンウェーハの片面研磨を行った。
実施例1における第1研磨工程の回転速度を変更してSiO2/Si研磨レート比を0.3とした以外は、実施例1と同様にして、100枚のシリコンウェーハの片面研磨を行った。
実施例1における第1研磨工程の回転速度を変更してSiO2/Si研磨レート比を0.1とした以外は、実施例1と同様にして、100枚のシリコンウェーハの片面研磨を行った。
実施例1および従来例1によるそれぞれのシリコンウェーハの研磨後の表面を、ウェーハ表面検査装置(Surfscan SP2; KLA-Tencor社製)を用いて、DICモード(DIC法による測定モード)により測定した。測定にあたって、凹凸形状の段差状微小欠陥の高さの閾値を3.4nmと設定し、この閾値を超える段差状微小欠陥の個数を求めた。こうして、DIC法により検出される欠陥個数が0個であったシリコンウェーハの枚数を、実施例1と従来例1とで確認した。実施例1では、100枚中93枚で段差状微小欠陥の発生が確認されず、一方、従来例1では、100枚中61枚で段差状微小欠陥の発生が確認されなかった。すなわち、実施例1では段差状欠陥の発生率は7%であり、従来例1では段差状欠陥の発生率は39%であった。実施例2,3についても、欠陥個数が0個であったシリコンウェーハの枚数を実施例1と同様に確認し、段差状欠陥の発生率を求めた。結果を下記の表2に示す。なお、従来例1では第1研磨工程と第2研磨工程の区別はなく一定のSiO2/Si研磨レート比で片面研磨を行ったが、表2中では第1研磨工程の研磨レートとして示す。
