The controller determines the posture of the transparent rectangular substrate with respect to the default posture using a time difference between a time point at which a first light of the two different lights is not transmitted through an edge of the transparent rectangular substrate and a time point at which a second light of the two different lights is not transmitted through the edge of the transparent rectangular substrate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Substrate treatment apparatus","description":"A substrate treatment apparatus includes a transport part to transport a transparent rectangular substrate, a substrate support part to support the substrate, light generators to irradiate two differe","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11534859","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
