Introduction to the job

The EUV source team in San Diego operates in a fast-paced, uniquely innovative and challenging environment to create and productize novel solutions to support an aggressive commercialization plan for the EUV technology within ASML.The Droplet Generation System Function is responsible for creating a steady stream of micron-scale droplets of molten tin injected into a vacuum vessel at a rate of tens of thousands per second, which generate EUV light when hit by infrared laser pulses.The functional team is fully responsible for development of the droplet generator, for integration and functional testing of the modules and sub-components, and for overall integration of the module within the system.

The complexity of the droplet generation requirements and corresponding organizational challenges put exciting demands on the Droplet Generation Staff Scientist , who will be working within a multidisciplinary team mastering complex engineering activities of significant technical depth related to multiple phases of the product development, including technology pathfinding, theoretical and experimental feasibility studies, design and development activities, integration and validation testing, problem solving and troubleshooting. Ideal candidates will be incredibly organized, have a strong knowledge of applied physics, metrology, controls, and experiment design, hands-on knowledge of diverse vacuum and gas pressurized equipment,and have a genuine desire to push the boundaries of these technologies forward.

This position requires access to controlled technology, as defined in the Export Administration Regulations (15 C.F.R. § 730, et seq.). Qualified candidates must be legally authorized to access such controlled technology prior to beginning work. These questions assist the Company in determining whether an individual qualifies for the position.Business demands may require ASML to proceed with candidates who are immediately eligible to access controlled technology.

Role and responsibilities

  • Guide development of high-level architecture for the formation of tin droplets in the EUV source, as well as metrology systems for measuring the performance of the system, in order to improve the EUV generation process; improve droplet formation models via experimental validation; build and maintain model improvement roadmaps.
  • Provide input to technology roadmaps and identify key scientific learning objectives and define corresponding experimental design to arrive at design guidelines, performance requirements and procedures for product development and engineering design.
  • Identification of key scientific learning objectives and corresponding experimental design which will further the technological progress of the Droplet Generation process.
  • Develop and execute module, sub-module and integrated system performance tests, analyze test results and extract actionable knowledge from sub-module to full-system levels.
  • Troubleshoot and isolate equipment problems in laboratory and integration testing, assist in analyzing, diagnosing, and troubleshooting problems in the factory and at customer sites remotely and in person.
  • Document learning and communicate knowledge to engineering and product development teams to guide product improvement and release of new product nodes.
  • Work independently and in teams to deliver on a stated objective, whether it be the pursuit of new knowledge, the demonstration of a new capability, or the characterization of existing performance.
  • Perform other duties as assigned.

Education and experience

  • Requires PhD degree in a STEM field with a minimum of 3 years of research and development experience; MS degree with equivalent experience will be considered.
  • Experience with semiconductor capital equipment development is a strong plus.
  • Deep understanding of scientific research methods and strong scientific curiosity.
  • Hands-on experience with complex system design and build, including rapid prototyping, characterization and troubleshooting, and system-level demonstrations.
  • Extensive experience with experimental data analysis and development of data analysis tools with, for instance, MATLAB or Python and data acquisition systems such as NI LabVIEW.
  • Familiarity with gas flow systems, particularly flow through long narrow tubes and flow-restricting geometry, vacuum systems design and operation.


Working at the cutting edge of tech, you’ll always have new challenges and new problems to solve – and working together is the only way to do that. You won’t work in a silo. Instead, you’ll be part of a creative, dynamic work environment where you’ll collaborate with supportive colleagues. There is always space for creative and unique points of view.
