The present invention relates to a device for electrostatic discharge
protection (ESD). According to an embodiment of the present invention, a
device for electrostatic discharge protection comprises a semiconductor
substrate, a plurality of field oxide films formed in predetermined
regions on the semiconductor substrate, a gate formed in a predetermined
region on the semiconductor substrate between the field oxide films, a
well pick-up region formed in a predetermined region on the semiconductor
substrate between the field oxide films, a source formed in a
predetermined region on the semiconductor substrate between the field
oxide film and the gate, a drain drift region formed in a predetermined
region on the semiconductor substrate between the gate and the field
oxide film, a drain active region of a concentration higher than that of
the drain drift region, the drain active region being formed in the drain
drift region, and an oxide film formed on the semiconductor substrate on
a boundary of the drain drift region and the drain active region.
Accordingly, the current concentrated on the surface of the device can be
uniformly distributed over the entire device.
