The first material layer and the second material layer are selected such that a selective deposition process of a metal material provides a metal material portion only on the second material layer, while no deposition occurs on the first material layer or isolated islands of the metal material are formed on the first material layer. Any residual metal material can be removed from the bevel and the back side by a wet etch to reduce or prevent metal contamination from the deposited metal material."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of selectively depositing floating gate material in a memory device","description":"Undesirable metal contamination from a selective metal deposition process can be minimized or eliminated by employing a first material layer on a bevel and a back side of a substrate, while providing ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9768270","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.
