Description
図1は、本発明の実施の形態1において準備するSiC半導体を概略的に示す側面図である。図2は、本発明の実施の形態1におけるSiC半導体の洗浄方法を示すフローチャートである。図1および図2を参照して、本発明の一実施の形態のSiC半導体の洗浄方法を説明する。本実施の形態では、SiC半導体として、図1に示すSiC基板2を洗浄する方法を説明する。
図4は、本発明の実施の形態1の変形例における酸化膜の形成に使用可能な装置を概略的に示す模式図である。図4を参照して、変形例のSiC基板の洗浄方法について説明する。変形例におけるSiC基板の洗浄方法は、図3に示すSiC半導体洗浄装置の代わりに図4に示すSiC半導体洗浄装置を用いる点において異なる。
図5は、本発明の実施の形態2におけるSiC半導体を概略的に示す断面図である。図6は、本発明の実施の形態2におけるSiC半導体の洗浄方法を示すフローチャートである。図7は、本発明の実施の形態におけるSiC半導体の洗浄方法の一工程を概略的に示す断面図である。図2、図5〜図7を参照して、本実施の形態におけるSiC半導体の洗浄方法について説明する。本実施の形態では、SiC半導体として、図5に示すように、SiC基板2と、SiC基板2上に形成されたエピタキシャル層120とを含むエピタキシャルウエハ100を洗浄する方法を説明する。
本発明例1のSiC半導体として、図8に示すエピタキシャルウエハ130を洗浄した。なお、図8は、本発明例1、2および比較例1で洗浄するエピタキシャルウエハ130を概略的に示す断面図である。
次に、30ppmの濃度を有するオゾンを含む超純水を25℃に加熱して、図4に示す枚葉式のSiC半導体洗浄装置を用いて、エピタキシャルウエハ130の表面130aに1slmの流量で供給した。このとき、エピタキシャルウエハ100の回転速度は200rpmであった。これにより、エピタキシャルウエハ130の表面130aに酸化膜を形成できる(ステップS2)ことを確認した。
本発明例2は、基本的には本発明例1と同様であったが、酸化膜を形成するステップS2において80ppmのオゾン水を50℃に加熱してエピタキシャルウエハ130の表面130aに供給した点において異なっていた。この場合にも、表面130aに酸化膜が形成されていたことを確認した。また、ステップS3においても、表面130aに形成された酸化膜を除去したことを確認した。
比較例1は、基本的には本発明例1と同様であったが、ステップS2において、20ppmのオゾン水をエピタキシャルウエハ130の表面130aに供給した点において異なっていた。この場合には、表面130aに酸化膜が形成されないことを確認した。このため、比較例1の洗浄後の表面130aは、不純物およびパーティクルがほとんど低減されていなかった。
