The gate electrode includes a capping pattern and a work function pattern that are sequentially stacked on the plurality of semiconductor patterns. The capping pattern includes a first metal nitride layer including a first metal element, and a second metal nitride layer including a second metal element whose work function is greater than a work function of the first metal element. The first metal nitride layer is disposed between the second metal nitride layer and the plurality of semiconductor patterns. The first metal nitride layer is thinner than the second metal nitride layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device","description":"A semiconductor device includes a plurality of semiconductor patterns that are sequentially stacked and spaced apart from each other on a substrate, and a gate electrode on the plurality of semiconduc","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11296078","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.
