- 格子状に形成された複数の分割予定ラインによって区画された表面側の領域にそれぞれデバイスが形成された板状の被加工物を切削ブレードで切削する被加工物の切削方法であって、
ダイアタッチフィルムとダイシングテープとが積層された積層テープの該ダイアタッチフィルムを該被加工物の裏面に貼着するとともに、該ダイシングテープの外周部を環状フレームに貼着し、フレームユニットを形成するフレームユニット形成ステップと、
該被加工物を、該積層テープを介して切削装置のチャックテーブルで保持する保持ステップと、
該チャックテーブルと該切削ブレードとを、回転する該切削ブレードの下端が移動する方向と該チャックテーブルの移動方向とが一致するように相対的に移動させ、該切削ブレードを該被加工物に切り込ませることにより、該ダイアタッチフィルムを残して該被加工物を切断する切削溝を該分割予定ラインに沿って形成する第1切削ステップと、
該第1切削ステップを実施した後、該チャックテーブルと該切削ブレードとを、回転する該切削ブレードの下端が移動する方向と該チャックテーブルの移動方向とが逆方向になるように相対的に移動させ、該切削溝の底で露出した該ダイアタッチフィルムを該切削ブレードで切断する第2切削ステップと、を備えることを特徴とする被加工物の切削方法。 - 該第1切削ステップで、該切削ブレードが該ダイアタッチフィルムに切り込む深さは5μm以下であることを特徴とする請求項1記載の被加工物の切削方法。
