How does a bright field tool work and how does a dark field tool work? Explain how does a bright field provide you data? How does a tool determine whether the defect is truly a defect and isolate it from noise? If I have a silicon wafer and put Metal lines on that wafer , walk me through the process steps to go from Silicon to Metal lines? What is your experience with inspection tool sets? Have you personally used them? Whats your experience submitting FA? How do you design a DOE? Why do we use multiple variables to design a DOE instead of one variable?
