    摘要: An ESD protection power clamp for suppressing ESD events. A clamping transistor having power source connections connected across the power supply terminals of an integrated circuit is connected to clamp the voltage during an ESD event. An RC timing circuit defines a time interval where ESD voltage for triggering the FET out of conduction. An inverter circuit connects the RC and timing circuit to the clamping FET. A dynamic feedback transistor is connected in series with one stage of the inverter and the power supply. During an ESD event, the feedback transistor delays the time for disabling the FET transistor, providing increased immunity against mistriggering of the clamping transistor, and forces the circuit to reset following the mistrigger event.

    摘要: Device structures, design structures, and fabrication methods for passive devices that may be used as electrostatic discharge protection devices in fin-type field-effect transistor integrated circuit technologies. A device region is formed in a trench and is coupled with a handle wafer of a semiconductor-on-insulator substrate. The device region extends through a buried insulator layer of the semiconductor-on-insulator substrate toward a top surface of a device layer of the semiconductor-on-insulator substrate. The device region is comprised of lightly-doped semiconductor material. The device structure further includes a doped region formed in the device region and that defines a junction. A portion of the device region is laterally positioned between the doped region and the buried insulator layer of the semiconductor-on-insulator substrate. Another region of the device layer may be patterned to form fins for fin-type field-effect transistors.

    摘要: Disclosed are embodiments of a self-protected electrostatic discharge field effect transistor (SPESDFET). In the SPESDFET embodiments, a resistance region is positioned laterally between two discrete sections of a deep source/drain region: a first section that is adjacent to the channel region and a second section that is contacted. The second section of the deep source/drain region is silicided, but the first section adjacent to the channel region and the resistance region are non-silicided. Additionally, the gate structure can be either silicided or non-silicided. With such a configuration, the disclosed SPESDFET provides robust ESD protection without consuming additional area and without altering the basic FET design (e.g., without increasing the distance between the deep source/drain regions and the channel region). Also disclosed are embodiments of integrated circuit that incorporates the SPESDFET as an input/output (I/O) pad driver and method embodiments for forming the SPESDFET and the integrated circuit.

    摘要: An electronic discharge (ESD) protection circuit for protecting an integrated circuit chip from an ESD event. The ESD protection circuit includes a stack of BigFETs, a BigFET gate driver for driving the gates of the BigFETs and a triggering the BigFET gate driver to drive the gates of the BigFETs in response to an ESD event. The BigFET gate driver includes gate pull-up circuitry for pulling up the gate of a lower one of the BigFETs. The gate pull-up circuitry is configured so as to obviate the need for a diffusion contact between the stacked BigFETs, resulting in a significant savings in terms of the chip area needed to implement the ESD protection circuit.
