    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.

    摘要： An electrostatic discharge protection device, methods of fabricating an electrostatic discharge protection device, and design structures for an electrostatic discharge protection device. A drain of a first field-effect transistor and a diffusion resistor of higher electrical resistance may be formed as different portions of a doped region. The diffusion resistor, which is directly coupled with the drain of the first field-effect transistor, may be defined using an isolation region of dielectric material disposed in the doped region and selective silicide formation. The electrostatic discharge protection device may also include a second field-effect transistor having a drain as a portion the doped region that is directly coupled with the diffusion resistor and indirectly coupled by the diffusion resistor with the drain of the first field-effect transistor.
