The structure and process of the Zener diode are compatible with Gate-Last high-k FET structures and processes. Lateral separation of diode and transistor structures is provided by modified STI masking. No additional photolithography steps are required. In some embodiments, the non-junction face of the uppermost diode terminal is silicided with nickel to additionally perform as a copper diffusion barrier."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Zener diode structure and process","description":"A vertically stacked, planar junction Zener diode is concurrently formed with epitaxially grown FET raised S/D terminals.
