Key Responsibilities
Process Optimisation
- Take ownership of assigned semiconductor processes, including diffusion, metallisation, and thermal treatment.
- Optimise and stabilise process parameters for high-yield, repeatable manufacturing.
- Develop and refine process recipes using data-driven experimentation.
Performance & Data Management
- Monitor Statistical Process Control (SPC) metrics, reporting yield and performance trends.
- Investigate process anomalies with structured methodologies (e.g., 8D, A3).
- Conduct post-mortems on yield loss, linking data with technical fixes.
Analysis & Troubleshooting
- Collaborate with Quality, Operations, and Maintenance to resolve complex issues.
- Identify continuous improvement opportunities via Lean Six Sigma principles.
Documentation & Communication
