If the average defect density is 2.5/cm² what is the yield if the die size is increased to that of an entire 5in wafer? On the average, how many such wafers must be fabricated to give one good die? If the cost of each wafer is £300, and wafer die size is 1 cm² what would be the average cost per good die?
