The alignment device further includes a light receiving unit disposed on a side corresponding to the surface of the substrate and configured to receive light that is emitted from the first lighting unit and then passes through a region outside the substrate and to receive light that is emitted from the second lighting unit and then reflected from the at least one mark. The position of the substrate is determined based on a result of light reception by the light receiving unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Position determining device, position determining method, lithographic apparatus, and method for manufacturing object","description":"A position determining device includes a first lighting unit configured to emit light to an edge portion of a rotating substrate and a second lighting unit configured to emit light to at least one mar","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9841299","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.
