Description
ブランケット層研磨実験により証明されているとおり望ましいルテニウム除去速度及び銅に対するルテニウムの選択性を発揮する多くの有望な化学的機械的研磨組成物は、種々のパターン付け基板(即ち、ルテニウム及び銅の両方の表面特徴を有する基板)により発揮されるデバイス構成を異ならせるための強力な研磨性能を発揮することができない。ルテニウム及び銅を含む基板の化学的機械的研磨中に生成する副産物には銅イオンが包含されているものと考えられている。更に、これらの銅イオンが次亜塩素酸ナトリウムオキシダントの分解をもたらすとも考えられている。驚くべきことに、本発明の方法に使用される次亜塩素酸ナトリウムオキシダントを含有する化学的機械的研磨スラリー組成物が、ルテニウム及び銅の両方の表面特徴を有する種々の異なるデバイス構成にわたって強力な研磨特性を発揮することが見出された。
化学的機械的研磨スラリー組成物
試験した化学的機械的研磨スラリー組成物は、表1に記載される。化学的機械的研磨スラリー組成物Aは比較配合物であって、本発明の範囲に含まれない。化学的機械的研磨スラリー組成物は、水酸化カリウム(KOH)を用いて表1に注記されるpHに調整した。
研磨実験は、表1に記載された化学的機械的研磨スラリー組成物(CMPC)を用いて、銅(Cu)、オルトケイ酸テトラエチル(TEOS)、Black Diamond(登録商標)SiCOH膜(BD)及び物理気相成長ルテニウム(RuPVD)ブランケットウェーハに実施した。本研磨実験は、1psi(6.89kPa)ダウンフォース、300ml/分の化学的機械的研磨スラリー組成物流量、93rpmのプラテン速度及び87rpmのキャリア速度下で、SP2310サブパッド及び1010溝パターンの付いたVisionPad(商標)VP3100ポリウレタン研磨パッド(Rohm and Haas Electronic Materials CMP Inc.から販売されている)を用いる、ISRM検出システムを取り付けたApplied Materials, Inc. Reflexion LK(登録商標)300mm研磨機を用いて実施した。Kinik(登録商標)32P−3FNダイヤモンドパッドコンディショナー(Kinik Companyから販売されている)を使用することにより、研磨パッドをコンディショニングした。研磨パッドは、7.0lb(3.18kg)のダウンフォースを用いて20分間コンディショナーで慣らし運転した。研磨パッドは、6lb(2.72kg)のダウンフォースで研磨パッドの中心から2.0〜13.7インチまで10掃引/分での研磨中に、更にその場でコンディショニングした。表2に報告されたCu及びRuPVD除去速度は、Jordan Valley JVX−5200T計測ツールを用いて求めた。表2に報告されたTEOS及びBD除去速度は、KLA−Tencor FX200計測ツールを用いて研磨の前後の膜厚を測定することにより求めた。研磨試験の結果を表2に示す。
