Abstract
A monitoring system is for a sealing apparatus that seals a substrate treatment apparatus by a housing and fills a space sealed by the housing with a predetermined gas atmosphere. The monitoring system includes: a laser sensor for a region, which a person can enter in a space between the housing and the substrate treatment apparatus, as a detection region; and a controller that outputs a control signal to the substrate treatment apparatus or the sealing apparatus based on a detection result by the laser sensor or outputs a notification signal based on the detection result.
