Zener diode breakdown voltage is controlled by doping levels in a doped area of an N-type well. One or more diodes connected in series between the SCR circuit and the input/output terminal of the device advantageously raises the snapback voltage of the SCR circuit. The use of nitride spacers between doped regions instead of gate oxide technology significantly reduces unwanted leakage currents."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electrostatic discharge protection device structures and methods of manufacture","description":"An ESD protection device comprising an SCR-type circuit including a PNP transistor and NPN transistor incorporates a Zener diode which permits the circuit to operate at comparatively low trigger volta","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9704849","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.
