The thin-film piezoelectric material element includes a surface layer insulating film disposed on side surfaces of the laminated structure part, a first top surface of the upper electrode film and a second top surface of the lower electrode film, and has a first through hole formed on a first top disposed part and a second through hole formed on a second top disposed part. Further, the surface layer insulating film has an upper electrode pad being in directly contact with a first inside exposed surface and a lower electrode pad being in directly contact with a second inside exposed 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, 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-9722169","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.
