Based on the above technical solution, light incident from a lower surface of the first medium layer is able to be totally reflected or scattered by the upper surface of the first medium layer, so that most of light cannot reach a logic or storage area on the front of the security chip, thereby achieving the purpose of resisting a laser attack."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Security chip, security chip production method and electronic device","description":"A security chip includes: a first medium layer; a second medium layer disposed on the first medium layer, where the first medium layer is an optically denser medium relative to the second medium layer","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11462490","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.
