Vertical junctions are formed between the polysilicon and the exposed substrate at the trench edges such that during a thermal cycle, the doped polysilicon will out-diffuse doping elements into the adjacent single crystal silicon advantageously forming a diode extension having desirable properties."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of manufacturing devices having vertical junction edge","description":"Techniques for forming devices, such as transistors, having vertical junction edges.
