capacitor shown in Figure1.The area of the capacitor is
10^4um . At 300 K. ni = 1.5*10^10cm
(a) Is the substrate doping N type or P type? Explain the
reason why?
(b) What is the thickness of the oxide in the MOS
capacitor?
(c) What is the doping concentration of the substrate, Nsub
? To obtain Nsub, guess and solve it iteratively.
(d) What is the value of the capacitance at position C on the
C–V curve shownin Fig.1?
(e) Sketch the energy band diagram of the MOS structure at
positions A, B, C, D, and Eon the C–V curve.
(f) At location B on the C–V curve, What is the band
bending ? Substituting the numerical values and solving
the quadratic equation.
