The structure of nanoscale metal oxide semiconductor field effect transistor (NANO MOSFET) is introduced.Its source and drain regions are made of metal and the channel is made of intrinsic silicon.Such structure can effectively avoid short channel effects.Through solving a set of device equations,we simulate and then analyze the basic characteristics of NANO MOSFET.The results show that the source drain conductance of NANO MOSFET changes dramatically when the gate voltage changes.The characteristics is desirable for digital applications,including memory cells.Simulation results also show that NANO MOSFET can be applied as small signal analog amplifier if properly biased.
