- 表面に複数のデバイスが分割予定ラインによって形成された略円形状のデバイス形成領域と、該デバイス形成領域を囲繞する外周余剰領域とを有するウェーハの加工方法であって、
ウェーハ表面側に保護テープを貼着し、ウェーハの該デバイス形成領域に対応する裏面側の領域のみを所定厚さ研削して該デバイス形成領域を所望厚さに薄化し、該裏面に凹部を形成するとともに、該外周余剰領域に裏面側に突出する環状凸部を形成する凹部形成工程と、
該凹部形成工程を実施した後に、該環状凸部と該凹部の境界に円形の分割溝を形成し該環状凸部と該凹部を分割する環状凸部分割工程と、
該環状凸部分割工程を実施した後に、ウェーハの裏面の該分割溝の内側全面にダイシングテープを貼着すると共に該保護テープを剥離し該環状凸部を除去する転写工程と、
該転写工程を実施した後に、該デバイス形成領域の分割予定ラインに沿って分割を行うデバイス形成領域分割工程と、からなり、
該転写工程では、ウェーハの裏面に沿って該ダイシングテープがウェーハの裏面の中央から径方向外側に向かって貼着されるウェーハの加工方法。
