Description
単結晶シリコンの基板ウェーハの提供、
基板ウェーハ上での酸化物層の生成、
基板ウェーハの裏側で、およびエッジ領域の表面上で、酸化物層を部分的に除去してその範囲を制限する、基板ウェーハの非対称的両側研磨、
基板ウェーハの表側でのCMP、
基板ウェーハの表側への単結晶シリコンのエピタキシャル層の堆積、および、
基板ウェーハからの酸化物層の除去、
というステップを含む。
CVD反応装置内で、直径300mmで表側が{100}方位である単結晶シリコンの基板ウェーハに、酸化物層を十分にコーティングした。その後、基板ウェーハに、まず、(硬い(材料をより多く除去する)研磨布を表側で使用し、柔らかい(材料をより少なく除去する)研磨布を裏側で使用する)DSPによる研磨を行ない、次に、CMPによる表側の研磨を行なって、基板ウェーハを洗浄した。
実施例からの特性を有する、さらに別の単結晶シリコンの基板ウェーハに、実施例と同様に単結晶シリコンのエピタキシャル層をコーティングした。しかしながら、酸化物層の生成は省略された。これを省略したことは、結果として生じた半導体ウェーハのエッジ形状に明らかな悪影響を与え、対応する表側ベースの平均ZDDの値は-120nm/mm2、対応するESFQRmaxは23nmであった。
Claims (4)

前記エピタキシャル層の表面を16個のセクタに分割し、エッジ除外部が1mmである状態での、前記半導体ウェーハの平均化された表側ベースのZDDが、-30nm/mm2以上0nm/mm2以下であり、
前記エッジ除外部が1mmであり、72個のセクタの各々の長さが30mmである状態での、前記半導体ウェーハのESFQRmaxが、10nm以下である、単結晶シリコンの半導体ウェーハ。 - 前記結晶方位は{100}方位である、請求項1に記載の単結晶シリコンの半導体ウェーハ。
- 前記結晶方位は{110}方位である、請求項1または2に記載の単結晶シリコンの半導体ウェーハ。
