Description
本発明は、多結晶シリコン(Poly−Si)膜を研磨するための化学機械研磨用スラリーおよびこのスラリーの製造方法に関するものである。詳しくは、本発明は、研磨停止層として機能する素子分離膜に比べて、多結晶シリコン膜に対して高い研磨選択性を有し、面内均一性(WIWNU)を改善することを可能にするスラリーを用いて、フラッシュメモリ素子の自己整列された浮遊ゲートの形成に有用な半導体素子の製造方法に関するものである。
半導体デバイスは、高性能、高集積化により512Mおよび1Gビット級のDRAMに代表される超大規模集積回路(ULSI)時代に突入している。デバイス製造の最小加工サイズが段々と小さくなるに伴い、次世代デバイスの製造には、60nmおよび70nmの線幅が適用されるようになっている。
本発明は前記の従来技術の問題点を考慮してなされ、本発明の目的は、前記高い選択性を有する化学機械研磨(CMP)用スラリーを提供することであり、これは、超純水中の金属酸化物研磨粒子と、非イオン性フッ素系界面活性剤および第4級アンモニウム塩基を含む添加剤との混合物を含む。
本発明の一つの態様に従えば、次の成分を含むことを特徴とする多結晶シリコン膜を研磨するためのCMPスラリー組成物;
(a) 金属酸化物;
(b) 第4級アンモニウム塩基、および
(c) 下記式(1)のフッ素系界面活性剤:
以下、本発明をより詳しく説明する。
以下、実施例によって、本発明をより具体的に説明するが、これら実施例は、単に説明の目的で提示するものであって、本発明の保護範囲を限定するものではない。
超純水12299.5gに20重量%TMAH200gを投入した。添加の10分後に、ポリオキシエチレンパーフルオロブチルスルホニルエステル0.5gをそこに投入した。反応器内で、この混合物に20重量%コロイダルシリカ2500gを加えた。得られた混合物を、500rpmで十分に撹はんし、3ミクロンフィルタを使ってろ過し、スラリーを得た。このスラリーを用いて、下記のような条件でウエハを1分間研磨した。研磨の前後でウエハの厚さを測定し、オプティプローブ(Optiprobe)を使って3mmのエッジを除いた98ポイント分析によりウエハの面内均一性(WWNU)を評価した。その結果を下記表1に示す。
・ 研磨パッド: IC1000/Suba IV K groove(Rodel社)
・ 研磨基板: F−Poly、PTEOS、8’’ ブランケットウエハ
・ 研磨条件
― プラテン速度: 70rpm
― ヘッド速度: 70rpm
― 圧力: 3.5psi
― 背圧: 0psi
― 温度: 25℃
― スラリー流量: 200ml/分
(実施例2)
ポリオキシエチレンパーフルオロブチルスルホニルエステルを1.0g投入したことを除き、実施例1と同様の方法でスラリーを得た。スラリーの研磨性能は、実施例1に記載したものと同様の手順に従って評価した。その結果を下記表1に示す。
ポリオキシエチレンパーフルオロブチルスルホニルエステルを1.5g投入したことを除き、実施例1と同様の方法でスラリーを得た。スラリーの研磨性能は、実施例1に記載したものと同様の手順に従って評価した。その結果を下記表1に示す。
TMAHを加えなかった以外は、実施例1と同様の方法でスラリーを得た。スラリーの研磨性能は、実施例1に記載したものと同様の手順に従って評価した。その結果を下記表2に示す。
上記の説明が示すように、本発明は、ディッシングの問題を解決することができ、最適な選択性および優れた面内均一性を有する、多結晶シリコン膜を研磨するためのCMPスラリー組成物を提供する。
