Internship - Imaging Physics R&D

ASML is hiring an Internship - Imaging Physics R&D in San Jose, CA, USA. Posted November 11, 2026. Applications close November 25, 2026. Checked against the employer's posting on November 12, 2026.

Introduction 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.

The Imaging Physics R&D team is based in San Jose, dedicated to imaging-related multi-physics research topics including photomask, projection optics, photoresist, etc.

We strive to provide the best computational lithography solutions to our customers with accurate and fast optimization algorithms on photomask design, scanner configuration, and scanner dynamic control.

The Imaging Physics R&D team also works closely with our headquarters in the system and module design of ASML’s next generation scanners. Roles and Responsibilities As a Imaging Physics R&D Intern, you will support research and development activities focused on advanced photomask modeling and computational lithography technologies.
