📋 Solution:
Semiconductor Yield Loss
Clarifying Questions:
• Is yield loss occurring across all fabs or specific lines?
• Has there been any recent change in equipment or materials?
Solution:
I would structure this around production process stability, supply inputs, and capital investment trade-offs.
- Production process stability
• Analyze defect rates across each stage of fabrication.
• Identify bottlenecks or process variability.
• Benchmark yields against historical and industry levels.
- Supply and material inputs
• Assess quality consistency of raw materials.
• Evaluate supplier changes or cost-driven substitutions.
• Identify contamination or handling risks.
- Capital investment and technology
• Evaluate need for equipment upgrades.
• Assess automation and process control technology gaps.
• Model ROI of yield improvement initiatives.
