Internship - Droplet Generation Research

ASML • San Diego, CA

7d

About The Position

ASML US, LP develops lithography machines that enable the production of advanced microchips. This internship is on a source research team working on technologies for next-generation, high-power extreme ultraviolet (EUV) light sources based on laser-produced plasma. The role focuses on molten tin droplet generation, a key part of the EUV process: producing stable droplets at high rates, speeds, and positional accuracy to fuel the plasma and synchronize the light source.

The intern will work across physics, engineering, and materials science to investigate droplet-generator technology. The work includes identifying scientific learning objectives, designing and conducting experiments, demonstrating system performance, analyzing test results, troubleshooting test-bench subsystems, and communicating findings to engineering and product development teams. The position calls for curiosity, innovation, strong experimental skills, and the ability to work independently and collaboratively in an early-stage research environment.

Requirements

• Ongoing PhD or MS degree in Materials Science, Physics, Chemical Engineering, Mechanical Engineering, or an equivalent field.
• Deep understanding of scientific methods for designing and executing research experiments with limited oversight is highly desired.
• Experience designing a DOE and building experimental test setups, including setup layout, design, rapid prototyping, metrology selection, troubleshooting, and upgrades, is highly desired.
• Ability to clearly and logically communicate ideas and knowledge to varied audiences.
• Demonstrated ability to manage and lead a research project involving multiple stakeholders and constraints.
• Demonstrated ability to work effectively as part of a team and lead investigation and research efforts.

Nice To Haves

• Coursework related to data analytics, acoustics, fluid flow, and high-strength materials.
• Experience with microfluidics, particularly liquid jet breakup and droplet coalescence; piezoelectricity; and/or acoustics.
• Experience with high-pressure applications such as water jet cutting, jet breakup, and nozzle design.
• Experience in ceramics, including design and fabrication of ceramic components.
• Experience with droplet formation, sprays, common-rail diesel, and/or injectors.
• Experience with ultrasonic cleaning and chemical cleaning or etching.
• Experience collecting and analyzing experimental data and developing data-analysis tools.
• Familiarity with MATLAB or Python and data acquisition systems such as NI LabVIEW.

Responsibilities

• Identify scientific learning objectives and design corresponding experiments to advance the EUV generation process.
• Demonstrate system-wide performance targets aligned with the future technology roadmap.
• Develop and execute system and subsystem performance tests, analyze results, and extract actionable knowledge from sub-module to full-system levels.
• Troubleshoot tin delivery subsystems, ultra-high-vacuum systems, and optical modules on test benches to improve understanding of droplet-generation fundamentals.
• Document research findings and communicate knowledge to engineering and product development teams to guide product improvement and new product releases.
• Work independently and in teams toward objectives involving new knowledge, new capabilities, or characterization of existing performance.
• Perform other duties as assigned or required.
