Description
ある量のAirvolV−107が、エアプロダクトインク(Air Products Inc.)から購入された。ポリビニルアルコールが、以下のように溶解された。すなわち、180gのポリビニルアルコールV−107および600グラムの水道水。混合物は混合され、すべてのポリビニルアルコールが溶解するまで、約100℃に加熱された。
本発明の他の部分は、ブラシの外表面からブリストルを破かずに、本発明の洗浄ブラシを型から効率的に取り外すことができるように、PVCブラシ型を準備する方法である。PVCブラシ型にPVAを注入する前に、テトラヒドロフラン(THF)およびパラフィンの好ましい混合物を、PVC型に加えることにより、PVAが顕著には上に固着しないコーティングが創出されることが判明している。記述された方法によって準備されたPVC型を使用する製造が完了する際に、手作業でブラシを型から容易に取り外すことができる。
このデータの裏づけのない例は、化学機械平坦化プロセスに続いて、銅金属層を有するウェハを洗浄することを記述する。ウェハは、洗浄システムの第1のブラシボックスに導入されることが可能である。第1のブラシボックスにおいて、洗浄化学物質は、ブラシのベースコアと互いにかみ合うコア多孔性パッド材料上の鋳型から形成されるブラシを経て、ウェハに加えることができる。第1のブラシボックスにおいてブラシを経て加えられた洗浄化学物質は、基板表面上の銅材料を水溶性形態に制御して変換する。銅材料は、ウェハの表面から制御された量の銅を除去するために、水溶性形態に変換される。ウェハは、第1のブラシボックスから第2のブラシボックスに移動させることができる。第2のブラシボックスにおいて、第2の洗浄化学物質が、ウェハの表面を洗浄し、かつブラシの銅を洗浄するために、第2のブラシボックスのブラシを経てウェハの表面に加えられることが可能である。第2の洗浄化学物質は、第1のブラシボックスの洗浄化学物質と同じ化学組成を含むことが可能である。ブラシを経て加えられる第2の洗浄化学物質の目的は、ウェハ表面から洗浄された可能性があるブラシの銅および他の材料を洗浄することである。第2の洗浄化学物質は、約3秒から約10秒の間、ブラシを経て加えられることが可能である。次に、ウェハは、第2の洗浄化学物質をウェハ表面およびブラシから除去するために、第2のブラシボックスのブラシを経て水を流すことによって、脱イオン(DI)水で濯ぐことができる。ウェハ表面は、約20秒から約40秒の間、濯がれることが好ましい。第2のブラシボックスにおける動作後、ウェハは、スピン、濯ぎ、および乾燥(SRD)部に移送されることが可能であり、その後、ウェハは、後の処理のために出力部に貯蔵されることが可能である。
このデータの裏づけのない例では、ブラシ基板と互いにかみ合うコア多孔性パッド材料上に鋳造されたブラシは、酸化物表面の制御された層を除去して、親水性表面を維持するために、エッチング剤と共に使用される。
このデータの裏づけのない例では、ブラシ基板と互いにかみ合う多孔性パッド材料を有するブラシが、マイクロプロセッサまたは動的ランダムアクセスメモリデバイスなどの集積回路を製造するプロセスの洗浄ステップにおいて使用される。
このデータの裏づけのない例は、コアブラシ上の鋳型を、どのように作製して、流体フィッティングおよび機械駆動フィッティングに結合することが可能であるかを示す。本発明の洗浄ブラシを製造する第1のステップとして、PVC型が提供される。型は、PVCパイプ、コア、およびPVCパイプの上にはめ込まれるエンドキャップからなる。PVCパイプは、標準的な円筒PVCパイプとすることができ、ブリストルを形成するための複数の適切なサイズの穴が、パイプ壁を通して穴開けされている。ブリストルホールの密度は、完成ブラシのブリストル密度と整合するように、1平方インチ当たり約70個である。エンドキャップは、パイプの各端部にはめ込まれるように提供され、それにより、型が充填されるとき、PVA材料が各端部から流れ出るのを防止する手段を提供する。コアが提供され、PVCパイプの中空円筒内部内の中心位置においてはめ込まれ、完成ブラシの中空内径を創出する。次に、プラスチックラップが、PVAがブリストルホールから流れ出るのを阻止するために、型の回りに加えられる。次に、エンドキャップが、パイプの下端部に配置され、型は、PVA混合物で充填される。
