• Perform routine process qualifications, tool matching, SPC monitoring, and defect analysis.

• Troubleshoot process excursions, identify root causes, and implement effective corrective and preventive actions.

• Work closely with equipment engineers to ensure tool readiness, uptime, and process stability.

3. Data Analysis and Problem Solving

• Analyze process, metrology, and defect data to identify trends, risks, and improvement opportunities.

• Lead or support root-cause analysis for process-related issues and yield loss.

• Use data-driven methods to improve process stability, throughput, and overall manufacturing performance.

• Provide technical recommendations based on experimental results and production data.

4. Documentation and Reporting

• Maintain accurate records of process parameters, experiments, qualifications, and results.

• Prepare technical reports, summaries, and presentations for engineering reviews and management updates.

• Update process specifications, operating procedures, and control plans as required.

• Ensure proper documentation of process changes and lessons learned.

5. Cross-Functional Collaboration

• Work closely with cross-functional teams including R&D, production, quality, equipment, and integration.

• Support shift engineers and technicians as needed to resolve process or tool-related issues.

• Participate in technical discussions, problem-solving meetings, and improvement initiatives.

• Contribute to smooth process integration and technology transfer activities.

6. Continuous Improvement

• Identify and lead continuous improvement initiatives to improve yield, efficiency, quality, and cycle time.

• Explore opportunities for process automation and smarter process control.

• Support lean manufacturing and operational excellence initiatives in the lithography area.

• Drive standardization and best practice sharing across tools and teams.
