• Architect control strategies utilizing SPC, FDC, APC, and advanced analytics.
• Establish equipment standards, chamber matching strategies, and process control methodologies.
• Lead technical reviews, risk assessments, and technology transfer activities.

Operational Excellence

• Own module KPIs including:
  • Tool Availability , COUP
  • Yield , Defectivity
  • Lot Holds , Cycle Time
  • Cost Reduction
• Drive systematic reduction of chronic tool and process issues through structured root-cause analysis.
• Lead recovery efforts for high-impact manufacturing excursions.
• Implement sustainable corrective and preventive actions that prevent recurrence.

Strategic Planning & Capital Management

• Develop business cases supporting capital investments, upgrades, and productivity projects.
• Influence equipment selection, supplier strategy, and technology roadmaps.
• Assess future manufacturing needs and identify capacity, capability, and reliability gaps.
• Provide recommendations balancing risk, cost, and operational impact.

Cross-Functional Leadership
