Abstract

The present invention is related to an Electrostatic Discharge protection device. This may be a semiconductor device such as a CMOS transistor, having a snap-back IV characteristic, in order to withstand ESD pulses. The device of the invention comprises an additional doped region, which influences the internal resistance of the substrate whereupon the device is built. This has a positive effect on the snap-back characteristic, putting the snap back trigger voltage and current at a lower value, compared to prior art devices.
