Internship - Droplet Generation Research

ASML • San Diego, CA

6d

About The Position

ASML US, LP develops lithography machines that enable leading chipmakers to produce smaller, more powerful microchips. Its research team develops technologies for next-generation high-power extreme ultraviolet (EUV) light sources based on laser-produced plasma. A key part of EUV generation is producing stable molten tin droplets at high rates, speeds, and positional accuracy. The intern will work across physics, engineering, and materials science to help define the droplet generator architecture for future EUV sources. The role calls for curiosity, innovation, strong technical understanding, and an experimental mindset to measure complex phenomena and better understand and control tin droplet behavior.

The intern will identify scientific learning objectives and design experiments, demonstrate system performance against future technology targets, test and troubleshoot systems and subsystems, analyze results, and communicate findings to engineering and product development teams. Work may be independent or collaborative and may involve tin delivery subsystems, ultra-high-vacuum systems, and optical modules on test benches.

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.
• Ability to clearly and logically communicate ideas and knowledge to various 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.
• Ability to work under deadlines.

Nice To Haves

• Coursework related to data analytics, acoustics, fluid flow, and high-strength materials.
• Experience designing a DOE and building experimental test setups, including setup layout, design, rapid prototyping, metrology selection, troubleshooting, and upgrades.
• Experience with microfluidics, 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 and the design and fabrication of ceramic components.
• Experience with droplet formation, sprays, common-rail diesel systems, and/or injectors.
• Experience with ultrasonic cleaning and chemical cleaning or etching.
• Experience with experimental data collection and analysis, including development of data-analysis tools.
• Familiarity with MATLAB or Python and data acquisition systems such as NI LabVIEW.

Responsibilities

• Identify key scientific learning objectives and design experiments that advance the EUV generation process.
• Demonstrate system-wide performance targets to support the future technology roadmap.
• Develop and execute system and subsystem performance tests, analyze test results, and extract actionable knowledge from submodule 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 findings and communicate knowledge to engineering and product development teams to guide product improvement and release of new product nodes.
• Work independently and collaboratively to deliver research, demonstrate capabilities, or characterize existing performance.
• Perform other duties as assigned or required.
