3. Tooling & Equipment Management

Maintain and optimize lapping and polishing equipment (single/double-sided polishers planetary systems).
Evaluate new tools pads slurries and coatings to enhance performance.
Develop predictive maintenance programs to ensure equipment reliability.

4. Defect Analysis & Root Cause Investigation

Perform failure analysis using optical microscopy interferometry and SEM.
Address process deviations and propose corrective actions to minimize yield loss.
Optimize edge rounding stress-relief polishing and surface conditioning techniques.

5. Process Automation & Efficiency Improvements

Implement automation and Industry 4.0 technologies for real-time process monitoring.
Develop standard work procedures and automation scripts for consistent polishing outcomes.

6. Environmental & Safety Compliance

Ensure handling of ZnSe follows EPA OSHA and material safety regulations.
Develop waste management protocols for slurry disposal and recycling.
Conduct risk assessments (FMEA HAZOP) for chemical exposure and process hazards.
