    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: RC-trigger circuits for a semiconductor controlled rectifier (SCR), methods of providing electrostatic discharge (ESD) protection, and design structures for a RC-trigger circuit. The RC-trigger circuit is coupled to an input/output (I/O) signal pad by an isolation diode and is coupled to a power supply voltage by a power supply diode. Under normal operating conditions, the isolation diode is reverse biased, isolating the RC-trigger circuit from the input/output (I/O) pad, and the power supply diode is forward biased so that the RC-trigger circuit is supplied with power. The isolation diode may become forward biased during ESD events while the chip is unpowered, causing the RC-trigger circuit to trigger an SCR configured protect the signal pad from ESD into a conductive state. The power supply diode may become reverse biased during the ESD event, which isolates the power supply rail from the ESD voltage pulse.

    摘要: Protection circuits, design structures, and methods for isolating the gate and gate dielectric of a field-effect transistor from electrostatic discharge (ESD). A protection field-effect transistor is located between a protected field-effect transistor and a voltage rail. Under normal operating conditions, the protection field-effect transistor is saturated so that the protected field-effect transistor is coupled to the voltage rail. The protection field-effect transistor may be driven into a cutoff condition in response to an ESD event while the chip is unpowered, which increases the series resistance of an ESD current path between the gate of the protected field-effect transistor and the voltage rail. The voltage drop across the protection field-effect transistor may reduce the ESD stress on the gate dielectric of the protected field-effect transistor. Alternatively, the gate and source of an existing field-effect transistor are selectively coupled provide ESD isolation to the protected field-effect transistor.

    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.
