Claims (1)
- 交差する複数の分割予定ラインが設定されたウエーハの加工方法であって、
表面チッピングを抑えることができる程度の細粒径の砥粒を含有した切削ブレードをウエーハの表面から該分割予定ラインに沿って切り込ませ、ウエーハの厚みの半分より浅く仕上げ厚みに至らない深さの複数の溝を形成する溝形成ステップと、
該溝形成ステップを実施した後、ウエーハの表面に保護テープを貼着する保護テープ貼着ステップと、
該保護テープ貼着ステップを実施した後、該保護テープを介してウエーハをチャックテーブルで保持する保持ステップと、
該保持ステップを実施した後、ウエーハに対して透過性を有する波長のレーザービームの集光点をウエーハ内部の該仕上げ厚みより裏面側に位置付けて、該レーザービームをウエーハの裏面に向かって該分割予定ラインに沿って照射して、ウエーハ内部に該分割予定ラインに沿う改質層を形成するとともに該改質層から伸長して該溝に達し該分割予定ラインに沿うクラック層を形成するレーザー加工ステップと、
該レーザー加工ステップを実施した後、ウエーハの裏面を研削手段で研削して該仕上げ厚みへと薄化するとともに該改質層を除去し、ウエーハを該分割予定ラインに沿ってチップに分割する研削ステップと、
を備えたことを特徴とするウエーハの加工方法。
