Preferably, the stack structure includes a first semiconductor layer on the fin-shaped structure and a second semiconductor layer on the first semiconductor layer and the first semiconductor layer and the second semiconductor layer include different materials."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for fabricating semiconductor device","description":"A method for fabricating a semiconductor device includes the steps of first forming a fin-shaped structure on a substrate, forming a dielectric layer surrounding the fin-shaped structure, performing a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11462441","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.
