The inclined protrusion may include: a tapered protrusion and a multi-stepped protrusion formed on the boundary surface of the metal layer according to an interval between the metal layer bonded to the ceramic base and a neighboring metal layer, wherein a multi-stepped protrusion having an inclination angle within a predetermined angle range with respect to the ceramic base may be formed on the boundary surface of the metal layer where stress is concentrated, such as the short edge, apex, corner, and the like, and a tapered protrusion may be formed on a remaining portion of the boundary surface of the metal layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ceramic substrate and manufacturing method therefor","description":"A ceramic substrate is provided in which an inclined protrusion is formed on boundary surface of a metal layer bonded to a ceramic base so as to increase bonding strength; and a manufacturing method t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11291113","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.
