ECE103 (W11) HW #6 Due date 3/10/11 1. A. Consider a Si p-substrate PMOS capacitor (NMOSFET) with N A =10 17 cm -3 , x 0 =10nm, and a metal gate. B. Consider a Si n-substrate NMOS capacitor (PMOSFET) with N D =10 17 cm -3 , x 0 =10nm, and a metal gate. a. For the PMOS, calculate the applied voltage and the electric field (at the Si-SiO 2 interface) to make the silicon surface intrinsic. What is the depletion width in this case? b. With no oxide fixed or mobile charges and no interface traps, calculate
