ASML US is looking to solve the problem of designing, developing, integrating, marketing, and servicing advanced lithography machines that are key to producing faster, cheaper, and more energy-efficient microchips. This specific role focuses on assisting with the design, testing, development, and troubleshooting of next-generation optical and opto-mechanical metrology sub-systems for the creation and control of EUV radiation.

Requirements

  • Optical design and tolerancing using CodeV or equivalent SW package.
  • Physical optics modeling with FRED or equivalent SW package.
  • Optical sensors alignment experience using diverse alignment strategy and tools like optical collimators, mechanical gaging and interferometers.
  • Optical sensor metrology test design and build.
  • Expertise with diverse optical technologies and devices: polarization devices, relays, objectives, light sources, fibers, camera and detectors.

Responsibilities

  • Perform Optical design, optical tolerancing and modeling with CodeV and/or Zemax.
  • Physical Optics Simulation (wave propagation, partial coherence calculation and other optical effects) in Matlab, FRED and CodeV or other suitable design tools.
  • Perform Polarization optics error budgeting and polarization modeling.
  • Building and aligning complex sensors using diverse mechanical, collimation and interferometry subsystems.
  • Test stand design and build: concept, error budget, realization.
  • Optical sensors Hardware build and debugging.

Other

  • The internships are expected to be 12 weeks in length and on-site at the San Diego campus for the summer of 2026.
  • Candidate must be in process of acceptance through the GEM Fellowship
  • Must be willing to work in a clean room environment, wearing coveralls, hoods, booties, safety glasses and gloves for entire duration of shift.
