Description
図1は、本発明の実施の形態1に係るバックグラインド装置を示す平面図である。表面保護テープが貼付けられたウエハ1がウエハカセット2にセットされ、搬送ロボット3によりアライメント機構4まで搬送される。次に、アライメント機構4によりウエハセンタリングが行われ、ウエハ1は搬送アーム5によりウエハ受け渡し部6まで搬送される。次に、研削処理ステージ7が紙面反時計回りに回転され、ウエハ1は1軸研削ステージ8まで移動される。1軸研削ステージ8において第1及び第2研削工程が行われる。
実施の形態2では第1研削工程の後に未研削領域18の幅を測定し、その測定した値を元に第2研削工程における第1の砥石の位置を決定する。その他の工程は実施の形態1と同様である。
