Description
はじめに、半導体デバイスの配線の形成方法を図1(a)〜(c)に従って説明する。半導体デバイスの配線は通常、次のようにして形成される。まず、図1(a)に示すように、半導体基板(図示略)の上に設けられてトレンチ11を有する絶縁体層12の上にバリア層13及び導体層14を順次に形成する。その後、化学機械研磨により少なくともトレンチ11の外に位置する導体層14の部分(導体層14の外側部分)及びトレンチ11の外に位置するバリア層13の部分(バリア層13の外側部分)を除去する。その結果、図1(c)に示すように、トレンチ11の中に位置するバリア層13の部分(バリア層13の内側部分)の少なくとも一部及びトレンチ11の中に位置する導体層14の部分(導体層14の内側部分)の少なくとも一部が絶縁体層12の上に残る。こうして絶縁体層12の上に残った導体層14の部分が半導体デバイスの配線として機能することになる。
バリア層13は、導体層14の形成に先立って、絶縁体層12の表面を覆うように絶縁体層12の上に形成される。バリア層13は、例えば、タンタル、タンタル合金又は窒化タンタルから形成される。バリア層13の厚さはトレンチ11の深さよりも小さい。
・ 本実施形態の研磨用組成物は、研磨用組成物1L当たり3g以下の六員環骨格に疎水性官能基を有するトリアゾールを保護膜形成剤として含有している。そのため、保護膜形成剤としてベンゾトリアゾールを含有する従来の研磨用組成物のように保護膜形成剤由来の有機物残渣が異物として研磨後の研磨対象物の表面に多く残存することがない。従って、本実施形態によれば、半導体デバイスの配線を形成するための研磨でより好適に使用可能な研磨用組成物が提供される。
・ 前記実施形態の研磨用組成物には、親水性官能基を持つ六員環骨格を有するトリアゾールを添加してもよい。親水性官能基を持つ六員環骨格を有するトリアゾールを研磨用組成物に添加すると、絶縁体層12及び導体層14を研磨する研磨用組成物の能力が向上する。このトリアゾールの六員環骨格の親水性官能基は、絶縁体層12及び導体層14に対してより高い研磨速度を得るためには、カルボキシル基又はアミノ基であることが好ましく、より好ましくはカルボキシル基である。より具体的には、前記実施形態の研磨用組成物に添加される親水性官能基を持つ六員環骨格を有するトリアゾールは、絶縁体層12及び導体層14に対してより高い研磨速度を得るためには、カルボキシベンゾトリアゾール又はアミノベンゾトリアゾールであることが好ましく、より好ましくはカルボキシベンゾトリアゾールである。
・ 前記実施形態の研磨用組成物は使用前に濃縮原液を希釈することによって調製されてもよい。
トリアゾール、水溶性高分子、過酸化水素(酸化剤)、コロイダルシリカゾル、pH調整剤及びアミノ酸を適宜に混合し、必要に応じて水で希釈することにより実施例1〜26,28〜55、参考例27及び比較例1〜10の研磨用組成物を調製した。各研磨用組成物中のトリアゾール、水溶性高分子、過酸化水素、コロイダルシリカ、pH調整剤及びアミノ酸の詳細並びに各研磨用組成物のpHは表1〜3に示すとおりである。
・ 半導体デバイスの配線を形成するための研磨で使用される前記研磨用組成物。これによれば、半導体デバイスの配線を形成するための研磨でより好適に使用可能な研磨用組成物が提供される。
