図1は、実施形態に係る基板処理システム1(基板処理装置の一例)の概略構成を示す図である。なお、基板処理システム1は、基板処理装置の一例である。以下では、位置関係を明確にするために、互いに直交するX軸、Y軸およびZ軸を規定し、Z軸正方向を鉛直上向き方向とする。
次に、処理ユニット16の構成について、図2を参照しながら説明する。図2は、実施形態に係る処理ユニット16の具体的な構成例を示す模式図である。図2に示すように、処理ユニット16は、チャンバ20と、基板処理部30と、液供給部40と、回収カップ50と、温度センサ60とを備える。
次に処理ユニット16に接続される基板処理システム1の配管構成について、図3を参照しながら説明する。図3は、実施形態に係る基板処理システム1の配管構成を示す模式図である。
次に、基板処理システム1を制御する制御装置4の詳細について、図4を参照しながら説明する。図4は、実施形態に係る制御装置4の概略構成を示すブロック図である。上述したように、制御装置4は、制御部18と記憶部19とを備える。
次に、実施形態に係る制御処理について図6を参照し説明する。図6は、実施形態に係る制御処理を示すフローチャートである。
基板処理システム1(基板処理装置の一例)は、温度センサ60(温度検出部の一例)と、算出部18bと、実行部18dとを備える。温度センサ60は、処理液が吐出されたウェハW(基板の一例)の温度を検出する。算出部18bは、温度センサ60によって検出された温度に基づいたウェハWのエッチング量Dを計算式(所与の計算式)を用いて算出する。実行部18dは、エッチング量Dに基づいて処理液によるウェハWのエッチング処理を実行する。
基板処理システム1は、式(3)に示す指数関数の計算式とは異なる指数関数の式を用いて、エッチング量Dを算出してもよい。指数関数の式は、予備評価データを用いて、ウェハWの温度とエッチング量D’と相関関係から算出された式である。例えば、基板処理システム1は、式(4)に示すアレニウス式を用いてエッチング量Dを算出してもよい。
