Description
気孔率(%)=(1−(多孔質層130の密度)÷3.2))x100
により求めることができる。
0は、多孔質層130の上面134を覆うと共に、上面134に形成された開放気孔130aの内部に浸入し、開放気孔130a内の多孔質層130の表面に接着する。これにより、多孔質層130と樹脂系塗料150との間の接着面積を大きくすることができる。従って、いわゆるアンカー効果によって、研磨パッド108を剥離する際に樹脂系塗料150が多孔質層130から剥がれることを防止することができる。従って、従来技術と異なり、硬い研磨テーブルの表面を粗くするための機械加工を行う必要がない。また、機械加工と比較して、大きな接着面積を得るために研磨テーブルの支持面の平面度を大きく低下させることもない。
面積を得るために研磨テーブルの支持面の平面度を大きく低下させることもない。
1.基板を研磨するための研磨パッドを支持する支持面を有する研磨テーブルであって、多孔質層と非多孔質層との積層体を備えており、
多孔質層は開放気孔が開口する表面を有しており、開放気孔内に樹脂系塗料が含まれており、
樹脂系塗料が、支持面の少なくとも一部を形成する、研磨テーブル。
2.樹脂系塗料が、多孔質層の表面の全体を覆うように配置される、1に記載の研磨テーブル。
3.多孔質層における、開放気孔の外側の表面が露出されており、支持面は、外側の表面及び樹脂系塗料によって形成される、1に記載の研磨テーブル。
4.多孔質層は、セラミック材料を含む、1〜3のいずれかに記載の研磨テーブル。
5.非多孔質層は、研磨テーブル内に冷却液を通すための流路を含んでおり、流路は、多孔質層と非多孔質層との接合面から離れた位置に形成されている、1〜4のいずれかに記載の研磨テーブル。
6.基板を研磨する研磨装置であって、1〜5のいずれかに記載の研磨テーブルを備える、研磨装置。
