- CMP研磨パッドの表面を洗浄する方法であって、
供給源からの強制送気された空気若しくは気体の流れ又はカーテンを、CMP研磨パッド基板の表面上に、真空吸引源の方へ170kPa(24.66psig)~600kPa(87psig)の圧力で吹き付けること、ここで、前記基板の表面に対して垂直に存在する垂直面から6~15°の角度での前記強制送気された空気若しくは気体の吹き付けは、前記基板の表面の幅全体を横切り、且つ前記強制送気された空気若しくは気体の供給源を通過する:一方同時に、
前記CMP研磨パッド表面の表面全体が、前記強制送気された空気若しくは気体に少なくとも1回は曝されるように、平坦なプラテン上に水平に配置された前記CMP研磨パッド基板を水平面に沿って搬送すること:及び
前記強制送気された空気若しくは気体の流れのカーテンが前記CMP研磨パッドの表面と接触するところの点から下流にある表面上の点で前記CMP研磨パッドの表面を真空吸引すること:
を包含する、
上記方法 - 前記強制送気された空気若しくは気体の供給源は、前記基板が前記強制送気された空気若しくは気体の供給源を通って搬送されるときに、前記基板の表面から20mm以下の位置にあり、前記強制送気された空気若しくは気体の流れ又はカーテンは、前記基板が強制送気された空気若しくは気体のカーテンを通って搬送されるときに、前記CMP研磨パッド基板の表面の幅全体を横断するカーテンを含む、請求項1に記載の方法。
- 前記CMP研磨パッドが真空吸引される点の下流の点で、前記CMP研磨パッドの表面をブラッシングすること、一方同時に、強制送気された空気の流れ又はカーテンを基板上に吹き付けること、及び真空吸引すること、をさらに含む、ここで、前記ブラッシングすることは、搬送中に、真空吸引中に、及び吹き付け中に前記CMP研磨パッドの表面にブラシ要素を連続的に接触させること、を含み、
前記ブラシ要素は、前記CMP研磨パッド基板の表面の幅全体を横断し、前記強制送気された空気若しくは気体の前記カーテンと真空吸引源とのそれぞれに平行に配置され、且つ真空吸引源の下流で前記研磨パッド基板に接触する、請求項1に記載の方法。
