    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: 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: Device structures, design structures, and fabrication methods for a metal-oxide-semiconductor field-effect transistor. A gate structure is formed on a top surface of a substrate. First and second trenches are formed in the substrate adjacent to a sidewall of the gate structure. The second trench is formed laterally between the first trench and the first sidewall. First and second epitaxial layers are respectively formed in the first and second trenches. A contact is formed to the first epitaxial layer, which serves as a drain. The second epitaxial layer in the second trench is not contacted so that the second epitaxial layer serves as a ballasting resistor.

    摘要: Disclosed herein are embodiments of non-planar capacitor. The non-planar capacitor can comprise a plurality of fins above a semiconductor substrate. Each fin can comprise at least an insulator section on the semiconductor substrate and a semiconductor section, which has essentially uniform conductivity, stacked above the insulator section. A gate structure can traverse the center portions of the fins. This gate structure can comprise a conformal dielectric layer and a conductor layer (e.g., a blanket or conformal conductor layer) on the dielectric layer. Such a non-planar capacitor can exhibit a first capacitance, which is optionally tunable, between the conductor layer and the fins and a second capacitance between the conductor layer and the semiconductor substrate. Also disclosed herein are method embodiments, which can be used to form such a non-planar capacitor and which are compatible with current state of the art multi-gate non-planar field effect transistor (MUGFET) processing.
