Abstract
Description
実施形態1.研磨粒子、多価金属ホウ酸塩、少なくとも1つの酸化剤、及び溶媒を含む、組成物。
以下の非限定的な例は本発明を説明する。
945mlの蒸留水へ、2.5g(6.19mmol)の硝酸鉄(III)九水和物(Fe(NO3)3 9H2O)、2.5g(40.3mmol)のホウ酸(H3BO3)、40.0g(253.2mmol)の過マンガン酸カリウム(KMnO4)、及び10gのSaint-Gobain製の平均(D50)粒径100nmであるαアルミナ粒子を、撹拌しながら添加することによって、水性研磨用スラリー組成物(S1)を調製した。全成分を合わせた後、スラリーのpHを、1N HNO3でpH2.1に調整した。添加した成分のモル量に応じて、総Fe3+イオン対総ホウ酸イオン(BO3 3-)のモル比は、1:6.5であった。
例2では、研磨粒子としてSaint-Gobain製の平均粒径100nmである1重量%ジルコニアを含むスラリー組成物を調製し、試験した。研磨粒子の種類を変更したこと以外は、ジルコニア研磨粒子を含有するスラリー(S8)は、例1のスラリーS1と同じ成分を含有し、同じ方法で調製された。
例3では、ホウ酸鉄含有スラリーを、アルミナ粒子の量の変化に関して調査した。
例4では、2つの酸化剤を含有するスラリー(S10)のNMRを、1つの酸化剤のみを含有するスラリーS1と比較した。2つのスラリー間の唯一の違いは、追加の酸化剤であった。
様々な濃度のホウ酸鉄及び酸化剤KMnO4を伴うスラリー組成物を比較して、炭化ケイ素のNMRへの影響を調査した。全てのNMR試験を例1と同じ方法で行い、同じベースラインスラリー(1重量%のαアルミナ粒子、4重量%のKMnO4、95重量%の水、及びpH2.1)も含めた。
本開示の例の全ての研磨用スラリーを、Strasbaugh 6EC片面研磨ツールを用いて、軸外4°炭化ケイ素ウェハの材料除去速度に対するそれらの影響について試験した。
研磨は以下の条件下において行った。
2パッケージキット.
2つのパッケージを含むキットを調製する。第1のパッケージは、Fe(NO3)3及び水を含む。キットの第2のパッケージは、アルミナ粒子、KMnO4、ホウ酸、及び水を含む。パッケージ1とパッケージ2とを組み合わせた後、更なる水は添加せず、pHを調整せずに、キットから作製された研磨用組成物(試料S14)が、4重量%のKMnO4、1.25重量%のホウ酸、0.2重量%のアルミナ粒子、及び1.25重量%のFe(NO)3を含有するように、各パッケージ中の成分の量が調整される。得られた研磨用組成物のpHは2.1である。
