Abstract
An electrostatic discharge (ESD) protection device includes a substrate; a source region of a first conductivity type in the substrate; a drain region of the first conductivity type in the substrate; a gate electrode overlying the substrate between the source region and the drain region; and a core pocket doping region of the second conductivity type within the drain region. The core pocket doping region does not overlap with an edge of the drain region.
