This is the first study to successfully achieve record DNA sensitivity (sub-ƒM) by self-aligned, maskless, dual-channel, and metal-gate-based thin-film transistor nano-wire FET. Both novel device architecture (dual-channel) and optimization of integration processes (microcrystalline silicon and self-aligned sidewall sub-50 nm critical dimension) of nano-wire FET enhance the sensitivity to biological...
A full-fledged surface potential based compact model for cylindrical gate transistors replete with physical effects such as polysilicon gate depletion, mobility degradation, quantum mechanical effects, short channel effects, leakage currents, and parasitic resistances and capacitances etc. is presented. For the first time we present calibration results of such a model to a cylindrical gate technology...
A novel transistor design which utilizes positive feedback to achieve steep switching behavior is proposed and demonstrated. The feedback (FB) FET exhibits very low subthreshold swing (~2 mV/dec) and high ION/IOFF ratio (~108) to allow for significant reductions in gate voltage swing (to below 0.5V). It is a new candidate to replace the MOSFET for future low-power electronic devices.
