Why Chip Yields Collapse: The Hidden Cost of Process Complexity

Stopped at a red light, Sean’s thoughts about engine efficiency shift into a meeting about wafer yield, where he reframes yield as a health metric—not just a financial one. He shows how increasing process complexity, not physics or any single tool, multiplies failure chances: even very high per-step success rates collapse into low final yield when you chain thousands of operations. Sean’s prescription is not more controls but fewer steps done intelligently. Using PRIZ Process Functional Modeling—classifying steps as productive, providing, corrective, or metrology—teams can remove compensating operations, lower failure accumulation, and raise overall yield. The future favors companies that systematically simplify rather than pile on complexity.
