Claims (2)
- ウエーハを研削するためにセグメント砥石を環状に配設した研削ホイールであって、
少なくとも厚みが異なる3つの該セグメント砥石を備え、該厚みが異なる3つのセグメント砥石を厚みの小さいセグメント砥石から厚みの大きいセグメント砥石の順に内周をそろえて環状に配設し隣どうしの該セグメント砥石に均等な隙間を備えたことを特徴とする研削ホイール。 - ウエーハを保持する保持面を有する保持テーブルと、該保持テーブルを所定の回転方向に回転させる保持テーブル回転手段と、請求項1記載の研削ホイールを装着して該保持テーブルの回転方向と同一方向に回転させるスピンドルユニットを有し該保持テーブルが保持したウエーハを研削する研削手段と、該研削手段を該保持面に対して垂直方向に移動させる研削送り手段と、該保持テーブルと該研削手段とを相対的に該保持面方向に移動させて保持テーブルが保持したウエーハの中心を該セグメント砥石が通過する位置関係に位置づける位置づけ手段とを備えた研削装置であって、
該位置づけ手段により、該保持テーブルが保持したウエーハの中心を該研削ホイールの内周から最外周までの環状エリア内に位置づけ、
ウエーハの上面を該セグメント砥石が研削する研削加工エリアは、該セグメント砥石の回転軌道でのウエーハの外周から中心までであって、
該セグメント砥石の並び順は、該研削ホイールの回転方向の前方側から後方側に向けてもっとも厚みの小さい該セグメント砥石からもっとも厚みの大きい該セグメント砥石への順に配設されていて、該保持テーブルが保持したウエーハの外周から該セグメント砥石を進入させウエーハを研削することを特徴とする研削装置。
