An approach that aims for zero failures by combining design margin, process control and tests that remove outlier chips, preventing defects from being built in or shipped. Because a car uses thousands of semiconductors, automotive defect rates are managed in ppm (parts per million) with zero as the goal.

Zero defects appears in 1 practice question across 1 topic, including Automotive Semiconductors and Functional Safety.
Answer: C. Targeting zero defects, prevent defects from being built in and escaping at every stage of design, manufacturing and test, and identify the cause of even a single defect to prevent recurrence
Car failures can endanger lives, and a single vehicle uses thousands of semiconductors, so the defect rate per component must be extremely low. Zero defect is a philosophy that targets zero defects and combines design margin, process control and testing that removes outlier chips to prevent defects from being built in and escaping. If even one defect occurs in the field, the root cause is analyzed and used to prevent recurrence. Inspection alone still lets defects slip through, so design and process control are also essential.
