Such a pedestal structure (which can be referred to herein as a footing flare pedestal structure) mitigates, and in some embodiments, entirely eliminates, the exposure of the embedded electrically conductive structure during the patterning of metal-containing layers formed atop the embedded electrically conductive structure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Footing flare pedestal structure","description":"Re-depositing of metal-containing particles of an embedded electrically conductive structure onto sidewalls of an overlying metal-containing structure is alleviated in the present application by provi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11302639","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.
