Abstract
Description
この基板処理装置では、処理室からの排気は共通の排気管により排気導入室へと導かれ、排気導入室を介して個別排気管へと分岐するが、排気導入室は連通孔を介して各個別排気管と接続されており、排気導入室内に設けられた連通孔を有する回転部材が回動することにより個別排気管のうちのいずれか一つと連通する連通孔を開放し、排気連通室と個別排気管を連通させる様になっている。また、各個別排気管は、排気連通室との連通口とは別に開放口を有しており、回転部材と一緒に回動する遮断部材により、排気連通室と連通している個別排気管の開放口を閉塞するとともに、排気連通室と連通していない個別排気管の開放口を開放し、開放した開放口から空気を導入して集合排気管へ外気を供給することにより、他の処理室内の排気圧が大きく変動することを防止している。
