发明名称 Fin thyristor-based semiconductor device
摘要 A semiconductor device having a thyristor-based device and a pass device exhibits characteristics that may include, for example, resistance to short channel effects that occur when conventional MOSFET devices are scaled smaller in connection with advancing technology. According to an example embodiment of the present invention, the semiconductor device includes a pass device having a channel in a fin portion over a semiconductor substrate, and a thyristor device coupled to the pass device. The fin has a top portion and a side portion and extends over the semiconductor substrate. The pass device includes source/drain regions separated by the channel and a gate facing and capacitively coupled to the side portion of the fin that includes the channel. The thyristor device includes anode and cathode end portions, each end portion having base and emitter regions, where one of the emitter regions is coupled to one of the source/drain regions of the pass device. The gate of the pass device is further adapted to switch the pass device between a blocking state and a conducting state via the capacitive coupling and form a conductive path between the source/drain regions. A control port is capacitively coupled to the base region of the end portion of the thyristor that is coupled to the source/drain region of the pass gate and is adapted to facilitate switching of the thyristor between blocking and conducting states.
