Abstract
Description
前記サセプタの上面に前記ウェーハを載置するための凹形状のザグリが形成されており、
前記ザグリは、前記ウェーハの外周部が接触して支持される外周支持部と、前記外周支持部の内側に位置して前記ウェーハと接触しない中央部とを有しており、
前記外周支持部は、前記中央部に向けて水平方向に対して5°より大きく10°より小さい角度で下がるように傾斜していることを特徴とする。
以下、本発明の第1実施形態を説明する。先ず、図1を参照してエピタキシャルウェーハ製造装置を説明する。図1の枚葉式のエピタキシャルウェーハ製造装置1は、1枚のシリコン単結晶基板W(以下ウェーハWという)に対してその表面上にシリコン単結晶膜を気相成長させる装置である。
次に、本発明の第2実施形態を上記第1実施形態と異なる部分を中心に説明する。本実施形態ではサセプタの構造が第1実施形態と異なっており、それ以外は第1実施形態と同じである。
外周支持部の傾斜角が6°、9°のサセプタを用いた場合の影響度はそれぞれ42%、18%であった。また、エピタキシャルウェーハの外周部にはスリップ転位は発生しなかった。
外周支持部の傾斜角が1°、3°、5°のサセプタを用いた場合の影響度はそれぞれ98%、78%、52%であった。また、エピタキシャルウェーハの外周部にはスリップ転位は発生しなかった。
外周支持部の傾斜角が10°のサセプタを用いた場合の影響度は17%であったが、エピタキシャルウェーハの外周部にスリップ転位が発生した。
