- 表面側に格子状に設定された複数の分割予定ラインによって区画された複数の領域の各々にデバイスが形成された被加工物を、各分割予定ラインに沿って個々のデバイスチップに分割して該被加工物から複数のデバイスチップを製造する方法であって、
該被加工物に吸収される波長を有する第1のレーザービームを該被加工物の外部から該表面側へ照射して、各デバイスチップの仕上がり厚さに相当する深さよりも深い穴を該複数の分割予定ラインが交差する交差部に形成する穴形成ステップと、
該被加工物の該表面側を保護部材で覆う表面保護ステップと、
該被加工物を透過する波長を有する第2のレーザービームの集光点を該仕上がり厚さに相当する深さよりも該被加工物の裏面側に位置する該被加工物の内部に位置付けた状態で、各分割予定ラインに沿って該裏面側から該第2のレーザービームを照射して、該第2のレーザービームが照射されていない領域に比べて強度が低い領域を該被加工物の内部に形成する内部加工ステップと、
該被加工物が該仕上がり厚さとなるまで該被加工物の該裏面側を研削すると共に、該被加工物を複数のデバイスチップに分割する裏面側研削ステップと、を備え、
該穴形成ステップでは、該穴として、該表面から該裏面まで貫通しない非貫通穴を形成することを特徴とする複数のデバイスチップを製造する方法。
