WebABSTRACT As the gate oxide thickness of a metal- oxide- semiconductor (MOS) transistor shrinks down to below 10nm, there is strong evidence that the carrier mobility in the conduction channel is reduced systematically with gate oxide thickness. WebConsider a Si/SiO 2 n-channel MOSFET with channel length L=1.25 μm, channel carrier mobility μ n =650 cm 2 /V-s, C ox =6.9x10 −8 F/cm 2, and V th =0.65 V. . Determine the oxide thickness tox. Using the square law relation, determine the channel width that would result in saturation drain current ID,sat=4 mA at VGS=5 V for this device.

Web5 Physics of MOSFET and MOSFET Modeling - 90 - For charge balancing, Q S = Q ox = Q dep, where depletion charge Q dep is equal to Qdep = qN Addep.The depletion thickness d dep is equal to d dep = 1/ 2 A S S qN 2 V ε. At inversion, V G = V tn and V S = 2 φF, d dep becomes maximum value. Thus, the The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET), most commonly fabricated by the controlled oxidation of silicon. It has an insulated gate, the voltage of which determines the conductivity of the device.
