Claims (2)
- 被加工物を保持する保持テーブルと、該保持テーブルに保持された被加工物を研削する研削手段と、該研削手段を被加工物に対して接近又は離反する方向に移動する研削手段送り機構とを備えた研削装置であって、
前記研削手段は、
該保持テーブルに保持された被加工物に対峙する多数の細孔を有する多孔質パッドと、
該多孔質パッドの上方に設けられた内部にゲル状スラリーを格納するゲル状スラリー格納部と、
該多孔質パッドと被加工物の間に水を供給する水供給手段とを具備し、
該多孔質パッドは少なくとも外周部に超砥粒を含み、
該多孔質パッドの細孔径はゲル状スラリーに含まれる超砥粒の粒子径より大きいことを特徴とする研削装置。 - 請求項1記載の研削装置を用いて被加工物の研削を行う研削方法であって、
前記研削手段送り機構により前記多孔質パッドを前記保持テーブルに保持された被加工物に接近する方向に研削送りし、該多孔質パッドを被加工物へ押圧して被加工物の粗研削を行った後に、
該多孔質パッドの被加工物への押圧力を弱めて、該多孔質パッドから流出するゲル状スラリーで被加工物の仕上げ研削を行う、
ことを特徴とする研削方法。
