Claims (2)
- 表面に分割予定ラインによって区画され複数のデバイスが形成されたウエーハの裏面からウエーハを構成する基板に対して透過性波長のレーザ光線を照射させ基板の内部で集光させ分割予定ラインに沿って基板の内部に改質層を形成するレーザ加工装置に用いて、該レーザ光線が集光され該改質層を形成に寄与しないレーザ光線が該改質層からデバイスに影響を与える漏れ光を検査する検査用ウエーハであって、
検査用基板と、該検査用基板の表面全面に所定の厚みで形成した下地層と、該下地層に積層させた金属箔とから構成され、
該下地層は、デバイスに影響を与える漏れ光のみを該金属箔で検出可能な厚みに形成された検査用ウエーハ。 - 請求項1記載の検査用ウエーハの使用方法であって、
該検査用ウエーハの裏面から該検査用基板に対して透過性波長のレーザ光線を照射させ該検査用基板の内部で集光させた集光点を該検査用ウエーハの面方向で直線に移動させ一直線の改質層を形成する改質層形成工程と、
該改質層形成工程の後、該検査用ウエーハの該金属箔を撮像し、該金属箔の表面に表れる金属箔変形が起きた最大幅を測定する幅測定工程と、
該幅測定工程で測定した金属箔変形の最大幅が分割予定ラインの幅内となるようにレーザ光線を調整する調整工程と、を備える検査用ウエーハの使用方法。
