Abstract
An ESD (Electro-Static Discharge) protection circuit includes a semiconductor substrate having an active region and field regions, isolating films formed in the field regions, a gate insulating film formed on the active region, and a gate electrode formed on the gate insulating film, first and second heavily doped impurity regions formed in a surface of the semiconductor substrate at sides of the gate electrode, a plurality of dummy gate electrodes formed on the second heavily doped impurity region and offset from the gate electrode, insulating sidewalls formed at the sides of the gate electrode and at sides of each of the dummy gate electrodes, and salicide films formed on a surface of the gate electrode, on surfaces of each of the dummy gate electrodes and on a surface of the first heavily doped impurity region.
