- 複数のデバイスが形成されたデバイス領域と該デバイス領域の周囲を囲む外周余剰領域とを表面側に有する円盤状の被加工物の裏面側を、円環状のホイール基台と該ホイール基台の一面側に環状に配置された砥石部とを有する研削ホイールの該砥石部で研削する被加工物の研削方法であって、
該被加工物の該表面側を保護部材で覆う表面保護ステップと、
第1の回転軸の周りで回転可能な円盤状のチャックテーブルで、該被加工物の該表面側を吸引して保持する保持ステップと、
該保持ステップの後、第2の回転軸の下端部に装着され、該チャックテーブルの直径よりも小さな直径を有し、且つ、該チャックテーブルの上方に配置された該研削ホイールを該第2の回転軸の周りで回転させ、且つ、該研削ホイールのうち該チャックテーブルの外周部側の上方に位置する第1部分の底部が該チャックテーブルの中心部側の上方に位置する第2部分の底部よりも高くなる様に、該第1の回転軸に対して該第2の回転軸を傾けた状態で、該研削ホイールと該チャックテーブルとが該第1の回転軸に平行な方向に沿って互いに近づく様に両者を相対的に移動させることにより、該被加工物の厚さ方向で該デバイス領域に対応する該被加工物の該裏面側の中央部を研削して、研削が施された円形の被研削部と該被研削部の周囲を囲み且つ研削が施されていないリング状補強部と、で構成される円盤状の凹部を該裏面側に形成する傾斜研削ステップと、
該傾斜研削ステップの後、該第2の回転軸が該第1の回転軸と平行になる様に該第2の回転軸の傾きを徐々に変化させながら該裏面側を研削する、傾き変化及び研削ステップと、を備えることを特徴とする研削方法。 - 該傾き変化及び研削ステップの後に、該研削ホイールの該第2の回転軸と該チャックテーブルの該第1の回転軸とを平行にした状態で、該研削ホイールと該チャックテーブルとが該第1の回転軸に平行な方向に沿って互いに近づく様に両者を相対的に移動させることで該被研削部を研削する、通常研削ステップを更に備えることを特徴とする請求項1記載の研削方法。
