摘要：An ESD clamping device comprises a plurality of fingers each comprising asource region of first conductivity type formed in a substrate of second conductivity type,a drain region of said first conductivity type formed in the substrate, and a gate formed
over the substrate and between the source and drain regions. At least one of the fingerseach has an ESD implantation region formed in the substrate and partially underlying thedrain region of the finger, the ESD implantation region being a heavily doped region ofsaid second conductivity type. Furthermore, at least one of the fingers has a gateextension portion projecting from the gate and demarcating an additional region in atleast the drain region of the finger, the additional region of said second conductivity typebeing electrically connected to at least one of the gate and the substrate of each of thefingers.
