- Provide rapid technical response to process excursions, equipment alarms, overlay defects, critical dimension (CD) shifts, and production interruptions.
- Lead structured root cause investigations and implement effective corrective and preventive actions.
- Drive improvements in tool uptime, throughput, capability, overlay performance, and process stability.
- Monitor and improve lithography process performance through statistical process control (SPC), defect analysis, and data-driven decision making.
- Support recipe optimization, process qualification activities, and continuous improvement initiatives focused on yield, cycle time, quality, and cost reduction.
What you'll need
- Bachelor's Degree in Engineering, Physics, Materials Science, Chemistry, Electrical Engineering, Mechanical Engineering, or a related technical field.
- Knowledge of semiconductor lithography processes, materials, and equipment.
- Understanding of exposure, alignment, overlay, focus, dose control, and critical dimension management.
- Strong troubleshooting and root cause analysis skills.
- Statistical analysis, process control, and data interpretation capabilities.
- Experience with yield improvement and defect reduction methodologies.
Nice to have
- 3+ years of semiconductor manufacturing experience.
- Experience supporting lithography, process engineering, equipment engineering, yield engineering, or manufacturing engineering functions.
- Experience with photolithography processes, exposure systems, track tools, and/or advanced patterning technologies.
- Experience with statistical process control (SPC), data analysis, and structured problem solving.
- Experience working in a high-volume manufacturing environment.
