Microelectric Circuit Design
Consider a poly-silicon wire of diameter 5 microns and length 1000 microns. The
electron mobility in the wire is 1350 cm^2/V-sec and the electron concentration in the poly-silicon is 10^15/cm3 .Assume the electron mobility is constant for all questions below .

a. What is the resistance of the wire?

b. How short do you need to make the wire to cut the resistance in half?

c. Would you increase or decrease the electron concentration to reduce the resistance?

d. How much would you change the electron concentration to cut the resistance in half?

e. Would you increase or decrease the diameter of the wire to decrease the resistance?

f. How much would you change the diameter of the wire to cut the resistance in half?

g. What is the resistivity of the wire? conductivity?

h. Using the original dimensions of the wire, how much current can you pass through the wire until a 5V signal is degraded 5% or more?
