Internship

About the Role

ASML is seeking a summer intern with a background in Materials Science, Chemistry, Physics, Mechanical Engineering, Electrical Engineering, Software/Data Science, or a related technical field to join the MDU (Module Delivery Unit) Defectivity Group in Wilton, Connecticut. The MDU Defectivity Group supports the development of controlled environments within advanced lithography systems, focusing on particle and molecular contamination. This internship offers an opportunity to contribute to the understanding and control of contamination at small scales, working alongside experienced engineers and multidisciplinary teams.

Key Responsibilities

As an intern within the MDU Defectivity Group, you may contribute in one or more of the following technical areas:

• Materials Science / Materials Engineering / Nanotechnology: material characterization, surface interactions, contamination, and material compatibility.
• Tribology: wear, friction, particle generation, and evaluation of coatings and materials.
• Physics: plasma, electrostatics, particle behavior, and material compatibility.
• Mechanical Engineering: small-particle behavior in gas flows and high-vacuum environments.
• Software / Data Analysis: data processing, statistical analysis, image processing, and particle-adder detection.
• Electrical Engineering: development of test equipment, instrumentation, automation, and scripting using tools such as Python or MATLAB.
• Chemistry: vacuum-compatible cleaning methods, contamination removal, coatings, surface treatments, and material characterization.

You will:

• Participate in the development and evaluation of lithography system functions, components, tooling, and test equipment.
• Collaborate with engineers, Architects, the Defectivity Delivery team lead, factory engineers, and other technical experts to develop concepts, perform engineering analyses, design experiments, build and test prototypes, and analyze experimental/system data.
• Design and execute experiments supporting defectivity and contamination-control projects.
• Analyze experimental and system data and translate results into practical engineering recommendations.
• Investigate technical problems using structured root cause analysis and scientific methods.
• Support development and characterization of materials, components, processes, tooling, or test equipment.
• Document technical work through clear test plans, analysis, and engineering reports.
• Present conclusions and recommendations based on scientific evidence to audiences with varying technical backgrounds.
• Collaborate effectively across disciplines, including mechanical, electrical, software, physics, chemistry, materials, and systems engineering.
• Work under the guidance of ASML Architects, Defectivity Delivery team lead, and senior engineering mentors supporting the development of advanced lithography equipment.

This position is located on-site in Wilton, CT and requires onsite presence. Must be available for 12 weeks for sessions starting 6/2/2027 or 6/14/2027.
