Abstract
【解決手段】酸素析出物層4を有するシリコンウェーハ1であって、該ウェーハの表面から酸素析出物層4に至るまでのDZ層5の深さを2〜10μm、かつ該酸素析出物層4の酸素析出物密度を5×107個/cm3以上とする。

Description
(1)酸素析出物層を有するシリコンウェーハであって、該ウェーハの表面から酸素析出物層に至るまでのDZ層の深さが2〜10μmであり、該酸素析出物層の酸素析出物密度が5×107個/cm3以上であることを特徴とするシリコンウェーハ。
かくして得られたウェーハに対して、表面にスピンコートにより均一にNi汚染を塗布したのち、900℃×30minの熱処理で拡散させ、その後、ウェーハ表層をHF溶液にて回収し、
誘導結合プラズマ質量分析(ICP-MS)にて測定し、残存汚染量を調査した。さらに、汚染度を評価するため、MOS酸化膜耐圧法(Gate Oxide Integrity(GOI)法)にてGOI良品率を測定した。GOI法は、ウェ−ハに熱酸化処理を施した後、電極を形成してウェ−ハにMOSを作製し、このMOSに電気的ストレスを与え、あらかじめ設定しておいた判定値による良品率や、酸化膜絶縁破壊に至るまでに該酸化膜に注入された総電荷量から該酸化膜の膜質を判定し、熱酸化処理前のウェ−ハの Light Point Defect (LPD)、加工欠陥、汚染度等を相対的に評価するものである。ここでは、表面にNiスピンコートした後、900℃×30minの熱処理を行い、その後、電極面積を作製し、GOI良品率を測定した。
この汚染についての評価結果を、表1に併記する。
