About the Role

This is a summer internship in the Defectivity Group, analyzing particle and molecular contamination, material compatibility, and cleaning methods for lithography systems. The internship offers direct mentoring from architects and senior engineers, focusing on contamination control at the nanometer scale inside EUV-class lithography systems. The intern scope is broad and multidisciplinary. This is an on-site role in Wilton, CT.

Key Responsibilities

• Contribute to the development and evaluation of lithography system functions, components, tooling, and test equipment.
• Work on projects that may involve systems incorporating robotics, mechatronics, precision mechanics, vacuum technology, and opto-mechanical components.
• Consider engineering specifications, system performance, lifetime, failure modes, root cause analysis, statistical analysis, measurement-system capability, and defectivity (particle) performance.
• 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.

Areas of Contribution (Potential)

• Materials Science / Materials Engineering / Nanotechnology: material characterization, surface interactions, contamination, and material compatibility.
