ASML US brings together the most creative minds in science and technology to develop lithography machines that are key to producing faster, cheaper, more energy-efficient microchips. We design, develop, integrate, market and service these advanced machines, which enable our customers - the world’s leading chipmakers - to reduce the size and increase the functionality of their microchips, which in turn leads to smaller, more powerful consumer electronics. Our headquarters are in Veldhoven, the Netherlands, and we have 18 office locations around the United States including main offices in Chandler Arizona, San Jose and San Diego California, Wilton Connecticut, and Hillsboro Oregon. Having joined the ASML family in 2016, HMI has become an integral part of our holistic lithography portfolio with innovative e-beam inspections solutions.

Job Mission

The mission of the job is to overcome the challenges of semiconductor metrology and inspection. As an Electron Optics Engineer, you will play a key role in concept design and evaluation of e-beam metrology and inspection systems.

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. Business demands may require ASML to proceed with applicants who are immediately eligible to access controlled technology.”

Job Description

Make conceptual electron optical design of scanning electron microscope for next generation e-beam metrology and inspection systems.
Simulate electron optical properties and performances of electron optics systems, and optimize design to meet system performance requirements. This includes simulation of electron source and electron optics column. Make detailed simulation and design reports.
Define requirements for electronic modules controlling the electron optics system based on simulation.
Design control methods for electron optical component.
Evaluate electronic and mechanical tolerance of electron optics system.
Develop new ideas to overcome design bottlenecks limiting the electron optical performance of the system.
Provide support to system integration team in troubleshooting for root causes.
Provide support to application engineers in developing new applications, live demonstration and result analysis.
Designing experiments for evaluating electron optics performance in system platform. Analyze data and characterize resolution, probe current, distortion, and other optical characteristics.
Provide input to system specification, system error budget and interfaces.


Master’s degree or PhD in physics, applied physics or engineering.
