摘要： An electrostatic discharge (ESD) MOS transistor including a plurality of interleaved fingers, where the MOS transistor is formed in an I/O periphery of and integrated circuit (IC) for providing ESD protection for the IC. The MOS transistor includes a P-substrate and a Pwell disposed over the P-substrate. The plurality of interleaved fingers each include an N+ source region, an N+ drain region, and a gate region formed over a channel region disposed between the source and drain regions. Each source and drain includes a row of contacts that is shared by an adjacent finger, wherein each contact hole in each contact row has a distance to the gate region defined under minimum design rules for core functional elements of the IC. The Pwell forms a common parasitic bipolar junction transistor base for contemporaneously triggering each finger of the MOS transistor during an ESD event.

摘要： A silicon-on-insulator (SOI) electrostatic discharge (ESD) protection device that can protect very sensitive thin gate oxides by limiting the power dissipation during the ESD event, which is best achieved by reducing the voltage drop across the active (protection) device during an ESD event. In one embodiment, the invention provides very low triggering and holding voltages. Furthermore, the SOI protection device of the present invention has low impedance and low power dissipation characteristics that reduce voltage build-up, and accordingly, enable designers to fabricate more area efficient protection device
