Abstract
Description
また、切削装置には、第1の撮像画と第2の撮像画とに基づきグルービング溝に対する切削溝の位置ズレ量を検出する検出部と、検出部が検出した位置ズレ量に基づき割り出し送り手段を制御してグルービング溝の幅の中心と切削溝の幅の中心とを一致させる制御部とを備えることから、グルービング溝の幅の中心に切削ブレードの中心を高精度に位置づけることができ、切削ブレードでグルービング溝の中心を切削することができる。
撮像カメラ21が第2の光を利用して撮像した第2の撮像画とに基づき、例えば第1の撮像画と第2の撮像画とを重ねて、グルービング溝に対する切削溝の位置ズレ量を検出する検出部23と、検出部23が検出した位置ズレ量に基づいて図1に示した割り出し送り手段18を制御する制御部24とが接続されている。制御部24は、CPU及びメモリを少なくとも備え、検出部23によって検出された位置ズレ量を記憶することが可能となっている。
このように、グルービング溝5と切削溝6とを容易に区別して認識できることから、検出部23によって、第1の撮像画100と第2の撮像画101とを重ねてグルービング溝5に対する切削溝6の位置ズレを検出することが可能となり、検出部23が検出した位置ズレ量に基づいて、制御部24が割り出し送り手段18を制御することで、切削ブレード172の位置を調整してグルービング溝5の最外幅L1の中心8と切削溝6の幅L2の中心9とを高精度に一致させることができる。よって、ウエーハWを良好に個々のチップに分割することが可能となる。
