Abstract: A semiconductor device and a method for forming such are provided, the device including: a substrate, a plurality of parallel active semiconductor patterns that extend through a drain-side region and a source-side region, a metal drain contact in the drain-side region, an active gate pattern, a first dummy gate pattern, and a second dummy gate pattern that all extend across the active semiconductor patterns, and a metal interconnect structure located in a region between the first and the second dummy gate patterns. The active semiconductor patterns are doped with a dopant in portions exposed by the dummy gates in dummy gate regions that include the gate cut regions of the first and second dummy gate patterns. The metal interconnect structure connects each of a second subset of the active semiconductor patterns to a respective at least one of a first subset of the active semiconductor patterns.

Abstract: The disclosed technology generally relates to electrostatic discharge protection devices that protect circuits from transient electrical events and more particularly to low-voltage triggered silicon-controlled rectifier devices implemented using a bulk fin field-effect transistor technology. In one aspect, an electrostatic discharge protection device comprises a low-voltage triggered silicon-controlled rectifier having an embedded grounded-gate n-channel metal oxide semiconductor structure implemented as a bulk fin field-effect transistor having a plurality of fin structures. The fin structures direct current from an avalanche zone to a gate formed over the fin structure. The electrostatic discharge protection device has a higher trigger current and a lower leakage current than a similar device having a planar embedded grounded-gate n-channel metal oxide semiconductor structure because the current flow is restricted by the fin structures.
