Electrostatic discharge protection device and method for manufacturing the same

Abstract

An electrostatic discharge (ESD) protection device for protecting an internal circuitry from being damaged during electrostatic discharge, and a method for manufacturing the ESD protection circuit are provided. The electrostatic discharge (ESD) protection device includes: a gate electrode over a substrate; first and second doping regions provided in the substrate exposed at both sides of the gate electrode, the first and second doping regions having the same conductivity type; a third doping region provided in the second doping region and having an opposite conductivity type to that of the second doping region; and fourth and fifth doping regions spaced apart from the gate electrode and provided in the substrate exposed at both sides of the gate electrode, the fourth and fifth doping regions having the same conductivity type as the first and second doping regions.
