Description
(1)研磨パッドの表面に砥粒を含有する研磨液を供給し、シリコンウェーハに対し前記研磨パッドを相対的に摺動させることで、シリコンウェーハの表面を研磨するシリコンウェーハの研磨方法であって、前記研磨液に含有する砥粒の数が、2×10 13 〜5×1013個/cm3 であることを特徴とするシリコンウェーハの研磨方法。
直径が300mmであるシリコンウェーハに対して、最終研磨工程の仕上げ研磨として、ポリウレタン製の研磨パッドの表面に砥粒を含有する研磨液を供給し、シリコンウェーハに対し前記研磨パッドを相対的に摺動させることで、シリコンウェーハ表面の研磨を行った。
評価用サンプル1〜6の各サンプルにおける、研磨に用いられた研磨液の条件(シリコンに対する研磨レート、含有成分)及び砥粒の条件(数、平均粒径、種類)を、表1に示す。また、各評価用サンプルについて3枚のウェーハを作製した。
上記で作製した各評価用サンプルについて、(1)PIDの個数、及び(2)ウェーハ表面の平坦度について評価を行った。なお、評価については、3枚の評価用サンプルを用意し、平均値を算出することで評価を行っている。
各評価用サンプルについて、KLAテンコール社製の「Surfscan SP2」を用いてウェーハ表面上に存在するサイズが35nm以上の欠陥の個数を計測し、Surfscan SP2により検出される欠陥のうちLPD−Nに分類される欠陥をPIDとして、PID個数の計測を行った。得られたPIDの個数は、直径300mmウェーハ換算、すなわち直径300mmウェーハの表面上における個数とし、次の基準に従って、すなわち、個数が3個以下を○、個数が3個超え10個以下を△、個数が10個超えを×として、PID個数の評価を行った。この結果を、表1に示す。
また、各サンプルについての、研磨液中の砥粒の数と発生したPID欠陥の数との関係を示したグラフを図3に示す。
各サンプルについてKLAテンコール社製の「WaferSight」を用いて、ウェーハ表面の平坦度を計測し、次の基準に従って、すなわち、平坦度が60nm以下を○、平坦度が60nm超えを×として、ウェーハ表面の平坦度の評価を行った。この結果を、表1に示す。
