Abstract :
The use of a substrate pump to achieve uniform npn protection in a multi-finger NMOS is reported for advanced CMOS technologies with silicide. The novel feature of this device technique is the implementation of a floating guardring to effectively pump the local substrate of the protection NMOS. SPICE simulations are presented to illustrate the device concept as well as the device design optimization.
