Abstract:
The present disclosure relates to a Dual Fin SCR device having two parallel fins on which cathode, anode, n- and p- type triggering taps are selectively doped, wherein one Fin (or group of parallel Fins) comprises anode and n-tap, and other Fin (or group of parallel Fins) comprises cathode and p-tap. As key regions of the proposed SCR (anode and cathode), which carry majority of current after triggering, are placed diagonally, they provide substantial benefit in terms of spreading current and dissipating heat. The proposed SCR ESD protection device helps obtain regenerative feedback between base—collector junctions of two back-to-back bipolar transistors, which enables the proposed SCR to shunt ESD current. The proposed SCR design enables lower trigger and holding voltage for efficient and robust ESD protection. The proposed SCR device/design helps offer a tunable trigger voltage and a holding voltage with highfailure threshold.

Claim (Index 22):
A semiconductor device comprising:\n a first fin configured on a substrate and comprising an anode and a n-tap region, wherein the first fin has a base region of first conductivity type (N-Well), and wherein the anode is of second conductivity type and n-tap region is of the first conductivity type; and a second fin configured on the substrate and parallel to the first fin, wherein the second fin comprises a cathode and a p-tap region, wherein the second fin has base region of the second conductivity type (P-Well), and wherein the cathode is of the first conductivity type and the p-tap region is of the second conductivity type.
