SYSTEM AND METHOD FOR ESD PROTECTION

摘要

An integrated circuit ESD protection system comprises: a local power supply bus, a local ground bus, a first local ESD clamp, and ESD ground bus disposed between local power supply and ground busses and coupled to the local power supply bus through the first local ESD clamp, and coupled to the local ground bus through the second ESD clamp. The local power supply bus, the local ground bus, the first ESD clamp, the second ESD clamp and the ESD ground bus are disposed on a substrate. A reduced capacitance bonding pad is disposed on the substrate. A shunting ggNMOS ESD structure triggered by a divider circuit comprises a gate boosting structure disposed in an n-well that is coupled to the bonding pad.
