ESD protection diode

摘要

The integrated circuit is arranged in a semiconductor body (2) with a connection pad (3) linked to the circuit via a connection line (4). Two lines connect to a respective power supply (VSS, VCC) of the circuit. An element, protecting the circuit from electrostatic discharge, is positioned between the pad and the circuit and is connected to at least one power supply. The element consists of a first conductivity type zone (8) protruding in the body. The element also consists of another zone (9) of a second conductivity type which protrudes in the body, and joins the first zone. The element is connected to at least to one power line or to one pad.
