The disclosure also relates to display glass substrates containing the depletion layer made by the disclosed process. In addition, the disclosure relates to methods of making thin-film transistors (“TFTs”) on these display glass substrates by depositing a Si layer directly on the chemically treated surface of the glass substrate, and annealing the Si layer to form polycrystalline silicon."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for forming a glass substrate with a depleted surface layer and polycrystalline-silicon TFT built thereon","description":"There is disclosed a method for chemically treating a display glass substrate by treating at least one surface of the glass substrate with a heated solution containing HCl to form a depletion layer at","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9722084","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.
