Job Description
KEY JOB DUTIES & RESPONSIBILITIES:
1. Process Development & Optimization
- Develop and optimize chemical-mechanical polishingand fine grinding techniques for ZnSe.
- Establish process parameters (abrasive selection pressure speed slurry composition pH control temperature).
- Reduce defects such as surface haze scratches subsurface damage and roughness through process improvements.
2. Production & Quality Control
- Implement statistical process control (SPC) for polishing uniformity.
- Define quality criteria (flatness roughness surface irregularities) based on interferometry.
- Work with the Quality Assurance team to ensure compliance with optical performance standards (ISO 10110 MIL-PRF-13830B).
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.
