The piezoelectric-material film includes a size larger than the upper electrode film, a riser end-surface and step-surface formed on a top-surface of the upper electrode film side. The riser end-surface connects smoothly with a peripheral end-surface of the upper electrode film and vertically intersects with the top-surface. The step-surface intersects vertically with the riser end-surface."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Thin-film piezoelectric-material element, method of manufacturing the same, head gimbal assembly and hard disk drive","description":"A thin-film piezoelectric-material element includes a laminated structure part having a lower electrode film, a piezoelectric-material film laminated on the lower electrode film and an upper electrode","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11289641","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.
