(A) Answer the following questions based on the C-V curve for an MOS capacitor shown in Figure 1. The area of the capacitor is 10+ m². At 300 K.(100) ₁ = 1.5×10¹0 cm-³ (a) is the substrate doping N type or P type? (10), Explain the reason why? (10) (b) What is the thickness of the oxide in the MOS capacitor? (20) (c) What is the doping concentration of the substrate, Nub? (20) To obtain Nub, guess and solve it iteratively. (d) What is the value of the capacitance at position C on the C-V curve shown in Fig. 1? (10) (e) Sketch the energy band diagram of the MOS structure at positions A, B, C, D, and E on the C-V curve. (10) (f) At location B on the C-V curve, What is the band bending, , ? (20) Substituting the numerical values and solving the quadratic equation, you can obtain the answer.
