Patent ID: 7135745

Claim:
A semiconductor device comprising: a fin having a top portion and a side portion and extending over a semiconductor substrate and further including two side wall portions extending from the substrate and the top portion between the two side wall portions and wherein the fin is a thin silicon fin having a width between the two side wall portions of between about 5 nanometers and 15 nanometers; a pass device comprising a channel between source/drain regions, the fin including at least a portion of the channel, the pass device further comprising a gate facing and capacitively coupled to a side portion of the fin that includes the channel and facing both of the side wall portions of the portion of the fin that includes the channel, the gate being adapted to switch the channel between a blocking state and a conducting state for passing current between the source/drain regions in response to a voltage applied thereto; a thyristor having anode and cathode end portions, each end portion including an emitter region and an adjacent base region, the base regions being coupled between the emitter regions, one of the emitter regions being coupled to one of the source/drain regions of the pass device; and a control port capacitively coupled to one of the base regions and adapted to facilitate switching of the thyristor between blocking and conducting states.
