Abstract
An electrostatic discharge (ESD) device includes a gate structure, disposed on a substrate. A drain doped region of a first conductive type is in the substrate, adjacent to a first side of the gate structure, wherein the drain doped region has a first impurity concentration. A first doped region of the first conductive type is disposed within the drain doped region and being at least distant from the gate structure by a distance. The first doped region has a second impurity concentration lower than the first impurity concentration.
