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
a. find the yield for both wafers.
b. find the cost per good die for both wafers.
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.
d. assume a fabrication process improves the yield from 0.92 to 0.95. find the defects per area
unit for each version of the technology given a die area of 200 mm2

Which of the following statements is incorrect in relation to processes: while, strictly speaking, at any instant of time, the cpu is running only one process, in the course of 1 second, it may work on several of them, giving the illusion of parallelism a process is just an instance of an executing program, including the current values of the program counter, registers, and variables processes can be created when an operating system is booted, created by the user, or a running process can create children processes there is a master process, which when started can last forever, and is not killable
