Abstract
A method of fabricating a salicide layer in an electrostatic discharge protection device. On a MOS transistor having a gate, a source region and a drain region, a salicide block layer is formed. The salicide layer is patterned to remaining covering the drain region only, and leaving the source region and other portions of the substrate exposed. The anti-reflection coating layer is then removed to expose the gate. A salicide layer is formed on the exposed source region, the gate and other exposed portion of the substrate, while the drain region is free from the salicide layer for being covered with the salicide block layer.
