The EUV Wafer Defectivity team at ASML focuses on improving wafer quality in advanced lithography systems. In this internship you will help uncover how defects impact system performance. The team uses diagnostic data to trace defect sources and prevent recurring issues. Your work in this internship will combine data analysis and machine learning. This internship offers a hands-on opportunity to contribute to real engineering improvements.
In this internship you will study defectivity metrics and connect them to system performance indicators. You will work with large datasets and explore machine learning methods to identify patterns and root causes. Your insights will support engineers in improving system reliability and performance.
Your main responsibilities will be:
Collect and structure wafer defectivity data and system performance indicators
Analyze defectivity metrics such as size and material composition
Apply statistical analysis to identify trends and correlations
Explore machine learning techniques to detect patterns and root causes
Collaborate with engineers and stakeholders to interpret data insights
Support performance analysis through data-driven recommendations
Present findings clearly to support technical decision-making
This is a master non-thesis internship for 6 months, 5 days per week (3-4 days on-site). The start date of this internship is as of September 2026.
To be suitable for the internship, you:
Are pursuing a master’s degree in data science, physics, materials science, or a related field
Have experience with machine learning and statistical analysis techniques
Are analytical and able to structure complex datasets into clear insights
Communicate clearly in English, both written and verbal
Are proactive, collaborative, and comfortable working with diverse stakeholders
Have experience with MATLAB
