Learning Objectives

  1. Recognize the significance of metrology in semiconductor manufacturing.
  2. Identify the types and causes of defects.
  3. Classify defects based on the pattern of their occurrence on a wafer.
  4. Recognize the methods used for defect review.
  5. Explain the key parameters required to characterize and control semiconductor manufacturing processes.
A semiconductor wafer with fewer defects, which is detected through semiconductor metrology, shows an increase in chip yield.
