Description
本発明の基板を研磨する方法は、ジルコニル化合物と組合せて酸化ケイ素砥粒を含有するケミカルメカニカルポリッシング組成物を使用するが、ここで、このケミカルメカニカルポリッシング組成物は、驚くべきことに、ジルコニル化合物を含まないこと以外は同一の組成物により示される二酸化ケイ素除去速度よりも、著しく(好ましくは、>500%)高い除去速度を有している。
好ましくは、本発明の基板を研磨する方法において、このケミカルメカニカルポリッシング組成物は、腐食防止剤を含まない。
比較実施例ZC1〜ZC2及び実施例Z1〜Z9のケミカルメカニカルポリッシング組成物は、表1にリストされる量の成分を合わせて残りを脱イオン水とし、塩酸により表1にリストされる最終pHまで組成物のpHを調整することによって調製した。次にこのケミカルメカニカルポリッシング組成物のゼータ電位は、Malvern製のZetasizerを用いて測定した。測定ゼータ電位は、表1に提供される。
