With the method, the radiation energy of the ultraviolet rays for cleaning the substrate can be flexibly adjusted. The objectives of efficiently removing the organic matter stick on the surface of the substrate and preventing the static damage to the circuit pattern of the substrate can be achieved. Thus, the quality and the yield of the productions can be promoted."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of cleaning substrate by ultraviolet rays with adjustable radiation energy","description":"The present invention is related with a method of cleaning a substrate by ultraviolet rays with adjustable radiation energy, comprising steps of: providing an ultraviolet ray light (10) and a substrat","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9700921","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.
