Assume a 15 cm diameter wafer has a cost of 12, contains 84 dies, and has 0.020 defects/cm2 . Assume a 20 cm diameter wafer has a cost of 15, contains 100 dies, and has 0.031 defects/cm2. Find the yield for both wafers. Find the cost per die for both wafers. If the number of dies per wafer is increased by 10% and the defects per area unit increases by 15%, fi nd the die area and yield

Air undergoes a constant pressure cooling process with no moisture added or removed. the air originally exists at 45 °c, 150 kpa and 35 % relative humidity. it is cooled until the temperature reaches 29 oc. determine (a) the relative humidity of the cooled air. (b) the dew point temperature of the cooled air in °c. (c) the heat removed during the cooling process in kj/kg. use the psychrometric chart to check your answers (this part will not be graded; however, it will you get comfortable using the psychrometric chart)
