An investigation of single- and multi-finger nMOSFETs for the output pin ESD protection in integrated circuits
This work is referring to the nMOSFET singer-finger, multi-finger structures under the Electro-Static Discharge (ESD) zapping, and to evaluate the current distribution situations. By using the TCAD and HSpice, because of the internal parasitic resistance differences in each one finger, which can cause non-uniform turned on. Meanwhile, with different interior parasitic capacitor on each nMOSFET type, which will be inflected the device high-current-injection behavior.
