Abstract:
1. A method of manufacturing a semiconductor device having a semiconductor substrate, the method comprising: forming a fin having a top portion and a side portion extending over the semiconductor substrate; forming a pass device comprising a channel between source/drain regions, wherein the fin includes 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; forming a thyristor having anode and cathode end portions, each end portion including an emitter region and an adjacent base region, the adjacent-base regions being coupled to each other and located between the emitter regions, one of the emitter regions being coupled to one of the source/drain regions of the pass device; forming at least one control port proximate to at least one of the adjacent-base regions; wherein forming the thyristor comprises: wherein the forming of the pass device includes forming a polysilicon layer over the fin to form source/drain contact regions.
