The intensity of the roughness-related second signal is captured with a plurality of pixels. The intensity captured by each pixel is compared with the intensities captured by neighboring pixels. It is defined whether or not the pixel is contained in an abnormal zone. The standard deviation of the intensity values captured by the pixels of the abnormal zone is extracted, and the size of the void-type defect associated with the abnormal zone is determined from the extracted standard deviation. A new device may be used for carrying out such a method."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for detecting defects and associated device","description":"A method for determining the size of a void-type defect in a top side of a structure comprising a top layer placed on a substrate, the defect being located in the top layer, includes introducing the s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10509214","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.
