Abstract
【解決手段】研磨パッド1の研磨面1aに、バフ加工等の機械的加工を施して、平坦性を改善し、前記研磨面のうねりが、周期5mm〜200mmであって、最大振幅40μm以下とし、これによって、当該研磨パッド1を用いて研磨されるシリコンウェハ等の被研磨物の平坦度を向上させるようにしている
【選択図】図1
Description
本発明の研磨パッドは、被研磨物の研磨に用いられる研磨パッドであって、前記被研磨物に圧接される研磨面を有し、前記研磨面のうねりが、周期5mm〜200mmであって、最大振幅40μm以下である。
この実施例および従来例では、ニッタ・ハース株式会社製の、シリコン研磨に好適な発泡径が比較的大きな発泡ウレタンパッドであるMHタイプの研磨パッドを使用した。
同図において、横軸は研磨パッドの研磨面上の位置に対応し、ラインL1は実施例1を、ラインL2は従来例1をそれぞれ示している。この研磨面のうねりの測定は、日立造船株式会社製の測定器HSS−1700を用いて行なった。
上述の実施例1および従来例1では、MHタイプの研磨パッドを用いたけれども、この実施例および従来例では、ニッタ・ハース株式会社製の発泡径が比較的小さな発泡ウレタンパッドであるICタイプの研磨パッドを使用した。
次に、実施例2−1、従来例2およびブレークイン後の従来例2の研磨パッドを用いて、8inchのTEOS膜付のシリコンウェハの研磨を、次の条件で行ない研磨レートを評価した。
Claims (3)
- 被研磨物の研磨に用いられる研磨パッドであって、
