Description
したがって、従来のようにレジスト塗布装置40内のウェハWの回転数を制御するために、塗布現像処理システム1内にテスト用ウェハを流してレジスト膜の膜厚を測定する必要がない。そのため、製品用ウェハのフォトリソグラフィー処理を行うシステムを停止させる必要をなくして、ウェハの所定の処理を円滑に行うことができ、ウェハの生産性を向上させることができる。
また、このようなウェハW上のパターンの高さHの測定は、ウェハW毎に行うことができる。これにより、レジスト塗布装置40内のウェハWの回転数の補正の精度が次第に向上し、フォトリソグラフィー処理が行われた後のウェハW上に形成されるパターンの精度が向上する。
また制御部130における制御についても、上記実施の形態においてはウェハWの回転数のみを制御するようにしていたが、これに限らずウェハWの回転時間、又は回転加速度のうち、いずれか1つを制御してもよい。またこれらの回転数、回転時間、回転加速度のうち、いずれか2つ又は3つを同時に制御するようにしてもよい。
