Webis the fermi potential of the body which increases with the decrease in temperature. Ni is the carrier concentration of intrinsic silicon, NA is the substrate doping concentration and KT/q=v t is the temperature dependant potential. γ represents the body effect parameter, q the charge of an electron and εox is the permittivity of oxide WebUniform Body Doping When the source/body junction is reverse-biased, there are two quasi-Fermi levels (Efn and Efp) which are separated by qVsb. An NMOSFET reaches threshold of inversion when Ec is close to Efn, not Efp. This requires the band-bending to be 2φB + Vsb, not 2φB.
