ABSTRACT For the first time, we have successfully fabricated gate-all-around twin silicon nanowire transistor (TSNWFET) on bulk Si wafer using self-aligned damascene-gate process. With 10nm diameter nanowire, saturation currents through twin nanowires of 2.64 mA/mum, 1.11 mA/mum for n-channel TSNWFET and p-channel TSNWFET are obtained, respectively. No roll-off of threshold voltages, ~70 mV/dec. of substhreshold swing (SS), and ~20 mV/V of drain induced barrier lowering(DIBL) down to 30 nm gate length are observed for both n-ch and p-ch TSNWFETs

    ABSTRACT: Silicon nanowire (SiNW) silicon-oxide-nitride-oxide-silicon (SONOS) flash memory devices were fabricated and their electrical characteristics were analyzed. Compared to planar SONOS devices, these SiNW SONOS devices have good program/erase (P/E) characteristics and a large threshold voltage () shift of 2.5 V in 1ms using a gate pulse of +14 V. The devices also show excellent immunity to short channel effects (SCEs) due to enhanced gate controllability, which becomes more apparent as the nanowire width decreases. This is attributed to the fully depleted mode operation as the nanowire becomes narrower. 3D TCAD simulations of both devices show that the electric field of the junction area is significantly reduced in the SiNW structure.

    ABSTRACT: Vertically stacked nanowire FETs (NWFETs) with gate-all-around structure are the natural and most advanced extension of FinFETs. At advanced technology nodes, many devices exhibit ambipolar behavior, i.e., the device shows n- and p-type characteristics simultaneously. In this paper, we show that, by engineering of the contacts and by constructing independent double-gate structures, the device polarity can be electrostatically programmed to be either n- or p-type. Such a device enables a compact realization of XOR-based logic functions at the cost of a denser interconnect. To mitigate the added area/routing overhead caused by the additional gate, an approach for designing an efficient regular layout, called Sea-of-Tiles is presented. Then, specific logic synthesis techniques, supporting the higher expressive power provided by this technology, are introduced and used to showcase the performance of the controllable-polarity NWFETs circuits in comparison with traditional CMOS circuits.

    ABSTRACT: Ambipolar transistors with on-line configurability to n-type and p-type polarity are desirable for future integrated circuits. Regular logic tiles have been recognized as an efficient layout fabric for ambipolar devices. In this work, we present a process/design co-optimization approach for designing logic tiles for double-gate silicon nanowire field effect transistors (DG-SiNWFET) technology. A compact Verilog-A model of the device is extracted from TCAD simulations. Cell libraries with different tile configurations are mapped to study the performance of DG-SiNWFET technology at various technology nodes. With an optimal tile size comprising of 6 vertically-stacked nanowires, we observe 1.6x improvement in area, 2x decrease in the leakage power and 1.8x improvement in delay when compared to Si-CMOS.
