    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 portion of a device layer of a semiconductor-on-insulator substrate is patterned to form a device region. A well of a first conductivity type is formed in the epitaxial layer and the device region. A doped region of a second conductivity type is formed in the well and defines a junction with a portion of the well. The epitaxial layer includes an exterior sidewall spaced from an exterior sidewall of the device region. Another portion of the device layer may be patterned to form fins for fin-type field-effect transistors.

    摘要: An integrated circuit having a CML driver including a driver biasing network. A first output pad and a second output pad are connected to a voltage pad. A first driver is connected to the first output pad and the voltage pad. A second driver is connected to the second output pad and the voltage pad. A first ESD circuit is connected to the voltage pad, the first output pad, and the first driver. A second ESD circuit is connected to the voltage pad, the second output pad, and the second driver. The first ESD circuit biases the first driver toward a voltage of the voltage pad when an ESD event occurs at the first output pad, and the second ESD circuit biases the second driver toward the voltage of the voltage pad when an ESD event occurs at the second output pad.

    摘要: Device structures, design structures, and fabrication methods for a drain-extended metal-oxide-semiconductor (DEMOS) transistor. A first well of a first conductivity type and a second well of a second conductivity type are formed in a device region. The first and second wells are juxtaposed to define a p-n junction. A first doped region of the first conductivity type and a doped region of the second conductivity type are in the first well. The first doped region of the first conductivity type is separated from the second well by a first portion of the first well. The doped region of the second conductivity type is separated from the second well by a second portion of the first well. A second doped region of the first conductivity type, which is in the second well, is separated by a portion of the second well from the first and second portions of the first well.

    摘要: Methods for responding to an electrostatic discharge (ESD) event on a voltage rail, ESD protection circuits, and design structures for an ESD protection circuit. An RC network of the ESD protection circuit includes a capacitor coupled to a field effect transistor at a node. The node of the RC network is coupled with an input of the inverter. The field-effect transistor is coupled with an output of the inverter. In response to an ESD event, a trigger signal is supplied from the RC network to the input of the inverter, which drives a clamp device to discharge current from the ESD event from the voltage rail. An RC time constant of the RC network is increased in response to the ESD event to sustain the discharge of the current by the clamp device.

    摘要: A semiconductor circuit for electric overstress (EOS) protection is provided. The semiconductor circuit employs an electrostatic discharge (ESD) protection circuit, which has a resistor-capacitor (RC) time-delay network connected to a discharge capacitor. An electronic component that has voltage snapback property or a diodic behavior is connected to alter the logic state of the gate of the discharge transistor under an EOS event. Particularly, the electronic component is configured to turn on the gate of the discharge capacitor throughout the duration of an electrical overstress (EOS) condition as well as throughout the duration of an ESD event. A design structure may be employed to design or manufacture a semiconductor circuit that provides protection against an EOS condition without time limitation, i.e., without being limited by the time constant of the RC time delay network for EOS events that last longer than 1 microsecond.
