Assume a 25 cm diameter wafer has a cost of $550, contains 80 dies, and has 0.04 defects/cm2 .

a) Compute the yield for this wafer.

b) Compute the cost per die for this wafer.

c) If the number of dies per wafer is increased by 10% and the defects per area unit increases by 15%, find the die area and yield.
