The method for producing a via comprises: employing a first etching process to partially etch a top film layer in an area that needs to form a via above an electrode, wherein the vertical etching amount achieved by employing the first etching process is less than the thickness of the top film layer; and employing a second etching process for which the vertical etching rate is larger than the lateral etching rate to etch the remaining part in the area that needs to form a via, until the electrode is exposed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for producing a via, a method for producing an array substrate, an array substrate, and a display device","description":"The invention relates to the field of display technologies, and discloses a method for producing a via, a method for producing an array substrate, an array substrate and a display device to prevent a ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9716117","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.
