Job title: Lithography Process Engineer

1. Process Development and Optimization

Operate, and optimize photolithography equipment, including Canon i-Line Stepper / Canon DUV stepper / Canon Scanner systems.

Hands-on DNS track experience to support lithography process setup, development, optimization, and tool performance improvement activities.

Define, develop, and tune process recipes, including focus, exposure dose, alignment, overlay, and other critical lithography parameters.

Support BCD technology development through process characterization, window expansion, and optimization activities.

Conduct process experiments, collect and analyze data, and implement improvements to enhance process robustness and performance.

Collaborate with R&D, manufacturing, and equipment teams to introduce and qualify new processes or process changes.

2. Process Monitoring and Control

Monitor lithography process performance to ensure consistent output, high yield, and stable operation.

Use DNS track knowledge to support process monitoring, track troubleshooting, and day-to-day manufacturing stability.

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.

Required Qualifications

Bachelor’s degree or higher in Materials Science, Chemical Engineering, Electrical Engineering, Physics, Microelectronics, or a related field.

Experience in Semiconductor Lithography Process Engineering.

Knowledge of BCD process technology.

Hands-on experience with Canon i-Line Stepper or Canon DUV stepper or Canon Scanner 

Understanding of lithography fundamentals, process windows, alignment, overlay, exposure control, and defect mechanisms.

Experience in process monitoring, SPC, troubleshooting, and root-cause analysis.

Ability to work independently and collaboratively in a fast-paced manufacturing environment.

Experience supporting tool qualification, process transfer, or technology ramp-up.

Exposure to inline process integration and yield improvement projects.

Good communication, documentation, and presentation skills.

 Basic DNS track hands-on experience
