An improved sensitivity capacitive fingerprint sensor has a capacitive sensor array including multiple sensor cells and electrically conductive, through-chip vias extending from connection points for sensor cell circuitry to a back side of the capacitive sensor array, a chip including active detection circuitry and electrical connection points, the electrical connection points being respectively connected to corresponding ones of the sensor cell circuitry connection points, and a cover plate, disposed above the sensor cells at a spacing of less than 25 μm."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of making a capacitive sensor","description":"A method of creating an improved sensitivity capacitive fingerprint sensor involves forming vias from a first side of a sensor chip having an array of capacitive sensors, making the vias electrically ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8499434","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.
