Consider a p-type semiconductor substrate with Na =10^15 cm^-3. A region of heavily p+ doped material is formed by ion implantation as shown in the sketch below.Derive an expression for the built-in voltage under equilibrium conditions.
Overflow occurs when a result is too large to be represented accurately given a word size. Underflow occurs when a result is too small to be represented correctly (for example, a negative result while doing unsigned arithmetic.).
A thermal oxide of thickness 120 nm needs to be grown on a silicon wafer (100) in dry oxygen. If the process integration issue requires having a temperature not higher than 1050 degreeC, determine the time required to obtain the desired thickness.
A meta dyne with a uniform air gap is driven at constant speed with a constant dc voltage applied to the q brushes the stator is unexcited. Determine the current in the two circuit and the voltage between the q brushes. what driving torque will be..
