A testing method of a strip width of a scribing slot is also disclosed. Graphics of the field oxide region simulating the LOCOS structure are provided on two sides of the isolated line, the step is artificially generated, a polysilicon gate graphic on a small size source region formed by photolithography can be displayed through online testing of the strip width or online displaying and checking of the strip width, thus a practical situation of the die can be known, an abnormity of the strip width and morphology of the polysilicon gate caused by a reflection of a substrate can be found instantly."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Structure and method for testing strip width of scribing slot","description":"A testing structure of a strip width of a scribing slot is provided, the structure includes a first isolated line (232) and a second isolated line (234) which are perpendicular to each other, the test","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9778577","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.
