Description
本発明に係る研磨対象物は、(a)ケイ素-窒素結合を有する材料と、(b)その他の材料と、を含む。
本発明において、研磨用組成物の砥粒として作用する有機酸固定シリカは、シリカに有機酸が固定化されてなるものである(本明細書中、「有機酸固定シリカ」を単に「砥粒」とも称する場合がある)。また、シリカとしては、研磨傷の発生を抑制する観点から、コロイダルシリカを用いることが好ましい。
本発明の研磨用組成物は、各成分を分散するための分散媒を含む。分散媒としては、水;メタノール、エタノール、エチレングリコール等のアルコール類;アセトン等のケトン類等や、これらの混合物などが例示できる。これらのうち、分散媒としては水が好ましい。すなわち、本発明の好ましい形態によると、分散媒は水を含む。本発明のより好ましい形態によると、分散媒は実質的に水からなる。なお、上記の「実質的に」とは、本発明の目的効果が達成され得る限りにおいて、水以外の分散媒が含まれ得ることを意図し、より具体的には、好ましくは90質量%以上100質量%以下の水と0質量%以上10質量%以下の水以外の分散媒とからなり、より好ましくは99質量%以上100質量%以下の水と0質量%以上1質量%以下の水以外の分散媒とからなる。最も好ましくは、分散媒は水である。
本発明では、研磨用組成物に、選択比向上剤を含有させることによって、(b)材料の研磨速度に対する(a)材料の研磨速度の比(選択比)を向上させることができる。
型式:Prominence + ELSD検出器(ELSD-LTII)
カラム:VP-ODS(株式会社島津製作所製)

本発明の研磨用組成物は、酸を含む。酸を含むことにより、窒化ケイ素等の(a)材料の研磨速度がより向上する効果が得られる。
本発明の研磨用組成物は、酸性領域、中性領域、塩基性領域のいずれかに調整されうるが、窒化ケイ素等の(a)材料の研磨速度向上の観点から、酸性領域に調整されていることが好ましい。
本発明の研磨用組成物は、本発明の効果が著しく妨げられない範囲で、酸化剤、錯化剤、防腐剤、防カビ剤等の、研磨用組成物に用いられ得る公知の添加剤を、必要に応じてさらに含んでもよい。
本発明の研磨用組成物の製造方法は、特に制限されず、たとえば、有機酸固定シリカ、選択比向上剤、酸、および必要に応じて他の添加剤を、分散媒(たとえば、水)中で攪拌混合することにより得ることができる。したがって、本発明は、前記有機酸固定シリカ、前記分散媒、前記選択比向上剤、および前記酸を混合することを含む、本発明の研磨用組成物の製造方法を提供する。各成分の詳細は上述した通りである。
上述のように、本発明の研磨用組成物は、(a)ケイ素-窒素結合を有する材料と、(b)その他の材料と、を含む研磨対象物の研磨に好適に用いられる。よって、本発明は、(a)ケイ素-窒素結合を有する材料と、(b)その他の材料と、を含む研磨対象物を、本発明の研磨用組成物で研磨する研磨方法を提供する。また、本発明は、(a)ケイ素-窒素結合を有する材料と、(b)その他の材料と、を含む半導体基板を前記研磨方法で研磨する工程を含む、半導体基板の製造方法を提供する。
本発明によれば、前記(b)材料に対する、前記(a)材料の選択比が、実施例の欄に記載のように、本発明に係る選択比向上剤を含有させない場合と比較して、向上する。
