2(a) Is the substrate doping N type or P type ?
2(b) Derive the equation which can be used to calculate the capacitance related to the state of MOS structure at position A.
2(c) What is the thickness of the oxide in the MOS capacitor ?
2(d) What is the doping concentration of the substrate (Nsub) ?
Just describe the equation which can be used to calculate Nsub by using the values of Vfb and Vt from the C-V curve in Fig.1.
2(e) What is the value of the capacitance at position C on the curve in Fig.1.
2(f) Sketch the energy-band diagram of the MOS structure at positions A, B, C, D, and E on the C-V curve. (Apply the concept of the intrinsic Fermi Level (Ei)).
