Abstract
【解決手段】 シリコンウェーハ1を300℃以上に加熱して酸素イオンを注入し、シリコンウェーハ1の内部に酸素の高濃度層2を形成する第1の工程と、第1の工程で得られたシリコンウェーハ1を300℃未満に冷却して酸素イオンを注入し、シリコンウェーハ1にアモルファス層3を形成する第2の工程と、第2の工程で得られたシリコンウェーハ1を酸素を5%以上含む混合ガスの雰囲気中で熱処理してBOX層4を形成する第3の工程とを備えるSIMOXウェーハの製造方法において、第3の工程は、熱処理の開始温度を1350℃未満とし、最高温度を1350℃以上に加熱する方法とする。これにより、BOX層4の厚膜化に伴い、SOI層6の表面、及びSOI層6とBOX層4との界面のラフネスの増加及び絶縁耐圧の低下を抑制することができる。
