The metal pillars are to be electrically connected to a first conductive trace portion and a second conductive trace portion formed on a printed circuit board where the first conductive trace portion and the second conductive trace portion are electrically isolated from each other and physically separated by a separation of a first distance. The current sense resistor is formed in a portion of the metal layer spanning the separation between the first and second metal trace portions, the first and second conductive trace portions forming terminals of the current sense resistor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Metal-on passivation resistor for current sensing in a chip-scale package","description":"A current sense resistor integrated with an integrated circuit die where the integrated circuit die is housed in a chip-scale semiconductor package includes a metal layer formed over a passivation lay","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8531004","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.
