Process & Device Support
- Partner with process and device engineers to support fabrication of III-V photonics devices.
- Optimize lithography performance for critical parameters such as:
- Linewidth (CD) control
- Overlay accuracy
- Defectivity reduction
- Support new product introductions (NPI) and technology transfers.
Continuous Improvement
- Drive initiatives to improve yield, tool throughput, and cost efficiency.
- Lead projects to reduce variation and improve pattern fidelity for optical device structures.
- Implement equipment upgrades, recipe improvements, and automation enhancements.
Installation & Qualification
- Support installation, bring-up, and qualification of new lithography tools and upgrades.
- Collaborate with OEM vendors (e.g., ASML, Canon, Nikon, TEL) on tool performance and issue resolution.
- Execute tool matching and cross-fab standardization where applicable.
Preventive Maintenance & Calibration
- Develop and refine PM procedures to ensure tool precision and stability.
- Ensure proper calibration of optical systems, alignment stages, and exposure settings.
- Maintain compliance with cleanroom and EHS standards.
Data Analysis & Problem Solving
- Analyze SPC data, fault logs, and yield metrics to identify trends and root causes.
- Use structured problem-solving tools (RCA, 8D, DOE) to resolve recurring issues.
- Leverage data analysis tools (JMP, Python, Excel) to drive decision-making.
Cross-functional Collaboration
- Work closely with process engineering, quality, manufacturing, and maintenance teams.
- Support cross-functional yield improvement initiatives and failure analysis efforts.
Required Qualifications
