Description
図1に示す切削ブレード60は、例えば、電鋳ハブブレードであり、円盤状に形成されたアルミニウム製の基台600と、基台600の外周部に固定した切り刃601とを備える。切り刃601は、図2に示すように、ダイヤモンド砥粒P1と光触媒粒である酸化チタン粒P2とを混在させ、ニッケルメッキの電鋳バインダーB1で固定して形成されている。
図3に示す切削ブレード61は、例えば、外形が環状のワッシャー型のレジンボンドブレードであり、図4に示すように、ダイヤモンド砥粒P1と光触媒粒である酸化チタン粒P2とを混在させ、フェノール樹脂のレジンバインダーB2で成型・固定した切り刃611を外周に備える。
図7に示すように、まず、搬出入手段12により、一枚のウエーハWが、ダイシングテープTを介して環状フレームFに支持された状態で、ウエーハカセット11から仮置き領域13に搬出される。そして、仮置き領域13において、位置合わせ手段14によりウエーハWが所定の位置に位置決めされた後、第一の搬送手段15aがウエーハWを吸着して仮置き領域13からチャックテーブル30の保持面300aへとウエーハWを移動させる。次いで、環状フレームFが固定部32によって固定され、ウエーハWも保持面300a上で吸引されることで、チャックテーブル30によりウエーハWが保持される。
保持工程が終了した後、保持工程でチャックテーブル30に保持されたウエーハWを切削手段6で切削する切削工程を開始する。切削工程においては、図示しない切削送り手段により、チャックテーブル30に保持されたウエーハWが−X方向に送られるとともに、撮像手段170によってウエーハ上面Waが撮像されて切削すべきストリートSの位置が検出される。ストリートSが検出されるのに伴って、切削手段6が図示しない割り出し送り手段によってY軸方向に駆動され、切削すべきストリートSと切削ブレード60とのY軸方向における位置合わせがなされる。
