  1. MOS Capacitor Picture

  2. MOS Electrostatics Condition is called flatband --- the voltage when this occurs is called flatband This state is the baseline operating case --- a capacitive divider has one free parameter

  3. MOS Electrostatics Depletion Condition --- gate charge is terminated by charged ions in the depletion region Part of this region is often referred to as weak-inversion

  4. MOS Electrostatics Inversion --- further gate charge is terminated by carriers at the silicon--silicon-dioxide interface

  5. MOS Structure Electrostatics

  6. MOS Electrostatics

  7. (k(Vg - VT) - Vs)/UT Qs = ln( 1 + e ) (Y - Vs)/UT Qs = e Depletion (k(Vg - VT) - Vs < 0) Inversion (k(Vg - VT) - Vs > 0) (k(Vg - VT) - Vs)/UT Qs = (k(Vg - VT) - Vs)/UT Qs = e MOS-Capacitor Regions Surface potential moving from depletion to inversion
