- 表面に形成された交差する複数の分割予定ラインで区画された各領域にそれぞれデバイスが形成されたウエーハを該分割予定ラインに沿って分割して複数のデバイスチップを形成するウエーハの分割方法であって、
ウエーハに対して透過性を有する波長のレーザビームの集光点をウエーハの内部に位置付けて該分割予定ラインに沿って該レーザビームをウエーハに照射して、ウエーハの内部に該分割予定ラインに沿った改質層を形成するレーザビーム照射ステップと、
該レーザビーム照射ステップを実施する前又は後に、基材と加熱により軟化する粘着層とを有する粘着テープをウエーハに貼着する粘着テープ貼着ステップと、
該粘着テープ貼着ステップを実施した後、該粘着テープを拡張することでウエーハに外力を付与してウエーハを該分割予定ラインに沿って分割して複数のデバイスチップを形成する分割ステップと、
該粘着テープを加熱して該粘着テープの該粘着層を軟化させるとともに該分割ステップで形成された隣接するデバイスチップの間に該粘着層を侵入させ、分割によって生じた分割屑を該粘着層に接着させる分割屑捕獲ステップと、を備え、
前記分割ステップと前記分割屑捕獲ステップとは同時に実施されることを特徴とするウエーハの分割方法。
