Silicon-on-insulator body-coupled gated diode for electrostatic discharge (esd) and analog applications

摘要

A body and dual gate coupled diode for silicon-on-insulator (SOI) technology is disclosed. The body and dual gate coupled diode is formed from a SOI field-effect transistor (FET) structure. The source of the SOI FET structure forms the first terminal of the diode. The drain of the SOI FET structure forms the second terminal of the diode. The SOI FET structure includes two gates, which are tied to the body of the SOI FET structure. An SOI circuit comprising at least one body and dual gate coupled diode formed from the SOI FET structure provides electrostatic discharge (ESD) protection.
