Abstract

チョクラルスキー法によって育成されたシリコン単結晶からなるＩＧＢＴ用のシリコン単結晶ウェーハであって、引き上げ速度マージンを拡大することが可能で、ＥＧ処理が必要でなく、ＩＧＢＴ用ウェーハとしての充分な厚さのＤＺ層を有しかつＩＧ能を有するとともに、抵抗率のバラツキが小さく、　前記ウェーハ全面に設けられ表面側にＩＧＢＴ用デバイスの形成されるデバイス領域と、該デバイス領域よりも裏面側に位置しデバイス形成後に除去されるゲッタリング領域とを有し、前記デバイス領域の厚さ方向寸法が１００～２００μｍとされ、結晶径方向全域においてＣＯＰ欠陥および転位クラスタが排除されており、格子間酸素濃度が８．５×１０１７ａｔｏｍｓ／ｃｍ３以下であり、ウェーハ面内における抵抗率のばらつきが５％以下である。
