The high-k gate dielectric layer is in contact with the base of the gate conductor and is present on the sidewalls of the gate conductor for a dimension that is less than ¼ the gate structure's height. The semiconductor structure also includes source regions and drain regions present in the semiconductor substrate on opposing sides of the gate structure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of removing high-K dielectric layer on sidewalls of gate structure","description":"A semiconductor structure, and method of forming a semiconductor structure, that includes a gate structure on a semiconductor substrate, in which the gate structure includes a gate conductor and a hig","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8481389","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.
