Abstract:
A electrostatic discharge (ESD) device with a salicide layer isolated by a shallow trench isolation, comprising:a P type substrate; an N well, formed in the P type substrate; a shallow trench isolation, formed in the N well; a gate structure, on the P type substrate other than the N well, wherein the gate structure has a first side and a second side, and the first side is near to N well; a source region, formed in the P type substrate at the second side of the gate structure; a first drain region at the first side of the gate structure, formed in the P type substrate and crossing an edge of the N well; a second drain region, formed in the N well, wherein the second drain region is isolated from the first drain region by the shallow trench isolation; and a salicide layer, formed on the gate, the source region, the first and the second drain regions.
