Description
図1は、本発明に係る熱処理装置1の構成を示す縦断面図である。図1の熱処理装置1は、基板として円板形状の半導体ウェハーWに対してフラッシュ光照射を行うことによってその半導体ウェハーWを加熱するフラッシュランプアニール装置である。処理対象となる半導体ウェハーWのサイズは特に限定されるものではないが、例えばφ300mmやφ450mmである(本実施形態ではφ300mm)。熱処理装置1に搬入される前の半導体ウェハーWには不純物が注入されており、熱処理装置1による加熱処理によって注入された不純物の活性化処理が実行される。なお、図1および以降の各図においては、理解容易のため、必要に応じて各部の寸法や数を誇張または簡略化して描いている。
次に、本発明の第2実施形態について説明する。第2実施形態の熱処理装置1の全体構成は第1実施形態と概ね同じである。また、第2実施形態の熱処理装置1における半導体ウェハーWの処理手順も第1実施形態と同様である。第2実施形態が第1実施形態と相違するのは、空気逃し機構の形態である。
次に、本発明の第3実施形態について説明する。第3実施形態の熱処理装置1の全体構成は第1実施形態と概ね同じである。また、第3実施形態の熱処理装置1における半導体ウェハーWの処理手順も第1実施形態と同様である。第3実施形態が第1実施形態と相違するのは、空気逃し機構の形態である。
次に、本発明の第4実施形態について説明する。第4実施形態の熱処理装置1の全体構成は第1実施形態と概ね同じである。また、第4実施形態の熱処理装置1における半導体ウェハーWの処理手順も第1実施形態と同様である。第4実施形態においては、より強い光拡散効果を得るために、上側チャンバー窓63の上面に複数の光拡散板を積層して設けている。
以上、本発明の実施の形態について説明したが、この発明はその趣旨を逸脱しない限りにおいて上述したもの以外に種々の変更を行うことが可能である。例えば、第1実施形態においては、光拡散板90の下面を擦りガラスとしていたが、これに代えて或いはこれに加えて、上側チャンバー窓63の上面を擦りガラスとするようにしても良い。上側チャンバー窓63の上面を擦りガラスとする場合、光拡散板90が載置される領域のみを擦りガラスとする。このようにしても、上側チャンバー窓63に、光拡散板90と上側チャンバー窓63との接触面に滞留する空気を逃がす空気逃がし機構が設けられていることとなり、第1実施形態と同様の効果を得ることができる。
