An upper canopy is provided along the upper edge of an opening portion on the mini-environment side to block down flow along the opening portion. The upper canopy provides a space in which inert gas supplied through a supply port provided in the pod flows into the mini-environment through the opening of the pod after circulating inside the pod. The down flow has no effect in this space, and the entrance of down flow into the pod can be prevented."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"EFEM system and lid opening/closing method","description":"An object is to prevent down flow gas from entering into a pod in an open state in an EFEM system.
