The shift thyristor has a laminated structure including semiconductor layers, and is provided to a mesa formed separately from the light emitting thyristors and the transfer diodes. The shift thyristor includes a first metal layer continuously provided to straddle the mesa, and a second metal layer, which is arranged in an upper layer than the first metal layer, and includes a first part and a second part arranged to be opposed to the first part across the mesa. The first part and the second part of the second metal layer are each electrically connected to the first metal layer in a region that does not overlap the mesa in a plan view."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor light emitting device having a shift thyrister with a laminated structure, exposure head, and image forming apparatus","description":"Provided is a semiconductor light emitting device including nodes each connected to a gate of a shift thyristor and a gate of a light emitting thyristor and transfer diodes arranged to connect the nod","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11275322","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.
