Description
図3に示すように、硬質基板2の表面2aとウェーハ1の表面1aとを対面させ、図4に示すように、硬質基板2の上にウェーハ1を貼着する。硬質基板2は、ウェーハ1の裏面1bの研削時にウェーハ1を支持できる程度の硬度を有し、かつ、屈曲性があって研削後の剥離が容易である材料、例えばポリエチレンテレフタレート(PET)を使用する。
樹脂3が固化した後、硬質基板2に固定されたウェーハ1の裏面1bを研削する。裏面1bの研削には、例えば図6に示す研削装置4を使用することができる。この研削装置4は、被加工物を保持して回転可能なチャックテーブル5と、チャックテーブル5に保持された被加工物を研削加工する研削手段6と、研削手段6を鉛直方向に研削送りする研削送り手段7とを備えている。
