Description
まず、本発明に係る熱処理装置について説明する。図1は、本発明に係る熱処理装置100を示す平面図であり、図2はその正面図である。熱処理装置100は基板として円板形状の半導体ウェハーWにフラッシュ光を照射し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。熱処理装置100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100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。また、図1~図3の各図においては、それらの方向関係を明確にするためZ軸方向を鉛直方向とし、XY平面を水平面とするXYZ直交座標系を付している。
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100の構成および半導体ウェハーWの処理手順は第1実施形態と同様である。第2実施形態においては、ダミーウェハーの管理形態が第1実施形態と異なる。
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2実施形態は、ダミーウェハーの熱処理を行う場合のみならず、ダミーウェハーの非加熱処理を行う場合にも適用することができる。非加熱処理とは、ダミーウェハーに対する熱処理を行わずに、インデクサ部101と熱処理部160との間にてダミーウェハーの搬送のみを行う処理である。このような非加熱処理は、例えば、搬送機構38のティーチング作業を行った後に、教示内容通りの位置にダミーウェハーを搬送できているか否かを確認するために行われる。熱処理の回数を重ねて劣化が進行したダミーウェハーには反りが生じている場合があり、非加熱処理であってもそのようなダミーウェハーを搬送機構38によって搬送しようとすると搬送トラブルとなることがある。ダミーウェハーの非加熱処理に第2実施形態を適用すれば、ダミーウェハーの変形に起因した搬送トラブルを未然に防止することができる。
