Description
チョクラルスキー法によりボロンドープ単結晶シリコンを育成し、(001)面が基板主表面となる口径200mmのウェーハを用意した。酸素イオン注入を基板温度550℃、加速電圧180keV、総注入ドーズ量4×1017cm−2にて行った。まず、本発明の実施例として、注入を4回に分割し、各分割を1×1017cm−2のドーズ量とした。ウェーハには、<110>方向外周に、方位をしめすノッチが形成されているが、各分割の注入線束の射影と<110>方向とのなす角度、φを、90度ずつ回転させた。各分割の注入中、当該角度φは一定とした。基板表面の法線と各分割の注入線束とのなす角度θは15度とした。同様の手順で、角度θを10〜16度まで1度ずつ変更させ、部分SOIを作製した。さらに、注入を2回に分割し、分割毎に角度φを180度間隔で変更、3回に分割し、分割毎に角度φを120度間隔で変更し、部分SOIを作製した。比較例として、分割なしの注入など表1に示した条件での注入も実施した。これらのウェハを熱処理炉に投入し、以下の2条件で熱処理を行った。
条件B:温度1350℃、雰囲気アルゴン+0.5%酸素、処理時間4時間
に続いて、それぞれ
温度1350℃、雰囲気アルゴン+70%酸素、処理時間3時間
作製された部分SOIウェハは表面酸化層をフッ酸で除去した後、分光エリプソメトリを用いて、SOI部分の表面シリコン層、埋め込み酸化層の厚さを測定した。その結果、各サンプル間に大きな違いはなく、熱処理条件によって、
条件A:表面シリコン層の厚さ=340nm、埋め込み酸化層厚さ=85nm
条件B:表面シリコン層の厚さ=175nm、埋め込み酸化層厚さ=105nm
であった。
