Description
図1は、基板処理装置10の一例を示す断面図である。本実施例における基板処理装置10は、例えば容量結合型平行平板プラズマエッチング装置である。基板処理装置10は、例えば表面が陽極酸化処理されたアルミニウムによって形成され、内部に略円筒形状の空間が形成されたチャンバ1を有する。チャンバ1は保安接地されている。チャンバ1は、チャンバ1の内側壁によって形成された略円筒形状の空間の中心軸が、図1に示すZ軸に一致するように配置されている。
図2は、チャンバ1および載置台2の位置関係の一例を模式的に示す図である。図3は、図2に示したチャンバ1のA−A断面の一例を模式的に示す図である。図4は、図2に示したチャンバ1のB−B断面の一例を模式的に示す図である。図3および図4に示したチャンバ1のC−C断面が図2に示された断面図に対応している。
ここで、デポの付着量と温度との関係について説明する。図5は、絶縁性部材45の下面におけるデポの付着量と温度との関係の実験結果の一例を示す図である。本実施例における基板処理装置10では、絶縁性部材45の内部に図示しない第1のヒータが設けられており、チャンバ1の側壁であって静電チャック6の位置と同程度の高さから上方の位置に図示しない第2のヒータが設けられている。また、図5〜図8において、「60/60℃」等は、「第1のヒータの温度/第2のヒータの温度」を表している。
なお、開示の技術は、上記した実施例に限定されるものではなく、その要旨の範囲内で数々の変形が可能である。
